Wheel/Tire fitment question? Look here first ya n00b! :)

Post by Mopar_Korean » Wed Feb 17, 2010 4:05 pm

So Im growing tired of people asking what tire/wheels will fit on their neons. As Im sure some of you know I work at Discount Tire/America Tire, here is our fitment guide for normal neons and SRT-4s straight from Delta 3 clearance. :lol: Of course anyone is welcome to add additional sizes. I will try to keep this post updated on tire and wheel fitment to reduce the number of new posts created asking about wheels and tires.

Here are some guidelines:

Do you have SRT-4 Struts on your non-SRT-4 and want to know what tire will fit?

Look at the SRT chart. Any tire a SRT can fit you can fit. The SRT and non SRT share the same suspension design aside from the spring perches being higher on the SRT strut resulting in a shorter coil spring.

Thoes with coil overs can get away with a taller tire as we have no extruding spring perches to worry about.

-Want to put 17" SRT wheels on your non SRT neon without changing to SRT struts?

You'll need to buy 205/40/17 or 205/45/17 tires. OEM 205/50/17 is to tall and will hit the string perches. A 205/40/17 or 205/45/17 tire is not recommended by any manufacture to be put on a 6' wide wheel. (will they still fit? Yes. Have people had any issues? Not that I know of. Is the tire under an excessive amount of stress being on a narrower rim? Again I cant be for sure but Im sure the tire manufactures are just protecting their asses from being sued.) The only 17" tire I found that IS recommended to be put on a 6' wide wheel is the 195/45/17 Yokohama S. Drive. They are $90 each on Tirerack.com.

Want to put 15" or 16" wheels on a SRT-4?

Any 15 or 16 inch tire that fits on the non srt neon will fit on the SRT4. As along as the user has found a 15 or 16 inch wheel that will clear the front calipers. As I recall there are some 15 or 16 inch Rotas and Kosei K1 wheels that will fit the SRT-4 Neon. I cannot confirm this as I dont own an SRT4.

Want to put 19's on your Neon?

I have 19 x 8 on my car with an offset of 38 if i'm correct. I have coilovers and did a little grinding to the front so I could turn the wheel better. I had a body shop cut and roll my front and just cut the lip on the rear. - Neonon19s

This doesn't cover EVERY tire and wheel combo out there. Its just to get you in the ballpark of fitment. For example some 16'' and 15'' wheels fit an SRT4 but its not listed. Thats because DTC wont show smaller then stock wheel sizes. However any 15" or 16" tire that fits a normal neon should fit an SRT4.

WOW thanks for this im shopping for new rims right now , and this will help out alot, it does give you the choice to punch in say a 19x8.5 does it. and give a tire and offset, i dont knmow if you can get a 19x 7.5 rim

Great info man, thanks :thumbup:

One thing you will want to change though...
Mopar_Korean wrote:However any 15" or 16" tire that fits a normal neon should fit an SRT4.
In the rear, yes. But the caliper is too large in the front to clear most 15". There are a few out there that do, but not many.

Unless you did mean "tire" figuring that someone already has wheels that fit.
If I could just figure out how to meld the Outback and the Neon into one car...

I dont know if your asking me if I can manually put in a wheel size and see if it will fit. I know there are a few people who put 19 and even 20 on their neons before. I can try it at work tomorrow and see? No fitment chart or site I have come across even lists a 19" wheel that will fit a neon let alone offset. Either way Im sure your going to have to run a low offset wheel to even keep the tire from hitting the inner fender/unibody. But this places your tire tread out of the fenders. So your going to have to stretch a tire or run a large amount of camber to get the tread back under the fenders.

Hopefully some mod can sticky this and I can continue to add info to the initial post. My goal is to cut down on "What tire will fit?" or "what offset do I need?" posts that clutter this section of the forum. :banghead:

I also plan on adding some info about tires, lug nuts, and a few other things to educate some people. Theres a lot to think about when getting a set or wheels and tires that many people dont realize. I just want to make sure everyone is safe. No one needs a wheel off.

This is only partially correct.

The aspect ratio has a lot to do with the recommended wheel width.

Yes this is true but the most common aspect ratios that a neon driver will use ranges from 40 to 55. All of which would work on a SRT wheel as the chart above verifies.

I looked it over a couple times and can't find where the chart verifies that.

If you look at any tire manufacuter that makes a 205/40 tire you will see that the minimum recommended wheel width is 7".

When I said look at the chart I just meant that the most common aspects ratios for the average neon driver is going to range from 40-55. I didnt mean it to apply with the 205 section width.

And when I stated that the 205 section width is the ideal size for the 6" SRT rim, I meant that this is what the factory uses. Also that this width will work on non-SRT neons that are still using non-SRT suspensions but want to fit SRT 17" wheels. There are many users that have 205-40-17 tires on their non-SRT neons with non-SRT struts. It seems that, in theory, you can also fit 205-45-17 tires on SRT wheels with Non-SRT struts and not rub the spring perches. However I have yet to see one post confirming this. When I do I will change the initial post. Im not saying you should run a 205-40-17 tire on a 6" wheel or that its a good idea, but if someone wants the wheels to fit, without spacers, and without SRT struts/coilovers/Blues, then its really the only option.

Technically the won't fit. Physicall they will.
Danteneon wrote:They won't be stretched, the will be bowed in somewhat. The tread of the tire will be out more than the rim. But since you can't run a 50 series tire, that's you best option.


Sorry for the confusion.

I got ya.

Yeah, they will fit and a lot of people have done it. Doesn't mean I would do it.

Also, there are a bunch of people that run 205/45/17s successfully.

Regarding the '205 on a 6" ' discussion, I have to disagree that it is the "ideal" size. A 205mm wide tire is over 8" wide. That's an inch of tire bulge on each side of the wheel. I run a 205 on my stock 15x6's and love them, but the fitment is unconventional to say the least. I personally hate tires that barely fit a wheel, looks better with some bulge. :)

Im kinda lost with the last few sentences. You love 205s on your 15x6" wheel, you hate tires that barley fit a wheel, but you like bulge? Am I missing something?

Remember folks. When a tire company says 205mm they measure from the outer edge of one sidewall to the inner edge of the opposing sidewall, after the tire is mounted to a test rim.
Rim Width Range

Because tires have flexible sidewalls, a single tire size will fit on a variety of rim widths. A tire's rim width range identifies the narrowest to the widest rim widths that the tire is designed to fit. The width of the rim will influence the width of the tire. A tire mounted on a narrow rim would be "narrower" than if the same size tire was mounted on a wide rim. NOTE: Because the overall diameter of a steel belted radial is determined by the steel belts, there is little, if any, change to the overall diameter of the tire due to differences in rim width.

The industry rule of thumb is that for every 1/2" change in rim width, the tire's section width will correspondingly change by approximately 2/10".

For example: a tire in the P205/60R15 size is measured on a 6.0" wide wheel and this size tire has an approved rim width range from 5.5" to 7.5" wide. The tire has a section width of 8.23" (209mm) when mounted on a 6.0" wide wheel. If that tire were mounted on all of the rims within its range, the tire's approximate section width would change.

Because of the different wheel widths used in the above example, there is a 8/10" projected difference in tire section width when comparing a tire mounted on the narrowest rim to the widest rim within its range. This may affect fenderwell and frame clearances when selecting optional aftermarket wheel and tire packages

Additionally, some vehicle manufacturers and tire companies have permitted rim widths that are not within the tire's original approved rim width range. For example: BMW has combined 235/40R17 sized tires on 17x7.5" rims (which are 0.5" less than the narrowest 8.0" wide rim listed for the size) on certain M3 models; and Chevrolet has combined P255/50R16 sized tires on optional 16x9.5" rims (which are 0.5" wider than the 9.0" wide rim now listed for the size) on certain Corvette models. While these applications have received the approval of the vehicle and tire manufacturers, staying within the approved rim width range helps assure that the tire's internal stresses are within its design parameters.


Section Width

A tire's section width (also called "cross section width") is the measurement of the tire's width from its inner sidewall to its outer sidewall (excluding any protective ribs, decorations or raised letters) at the widest point. This measurement is made without any load placed upon the tire and after the tire has been properly mounted on its industry assigned measuring rim and has been inflated and reset to its test pressure after 24 hours.

Because a tire's section width is influenced by the width of the rim upon which the tire is mounted, the correct industry assigned measuring rim width for the tire size being measured must be used.

The width of a tire mounted on a narrow rim would be "narrower" than if the same tire was mounted on a wide rim. NOTE: because the overall diameter of a steel belted radial is determined by the steel belts, there is little, if any, change to the overall diameter of the tire due to differences in rim width.


Again I will state that when I said 205 is the ideal width for a 6" wheel I was talking exclusively for the 17" SRT wheel and a neon application, the fact the Dodge did it from the factory, and Im sure you would have some traction issues if you used a narrower tire. There is NO other option for people who want to run 17" SRT wheels on their non-SRT suspension. No company I know of makes a 195 or 185 section width that will fit a 17" wheel. So a 205 is your only choice. Plain and simple.

*Edit* I take that last statement back. The only tire I found that is designed to work on a 6" wide wheel with a 17" diameter and that will still fit on a non-SRT suspension is a 195/45/17 Yokohama S. Drive. It has a overall diameter of 23.9". A 205/40/17 tire has roughly 23.5" OD and a 205/45/17 has roughly 24.3 OD. Both of which have been proven to fit on a non-SRT suspension neon. So if a user wants a correct tire they need to fork over $90 a tire to have "correct" fitment.

I meant barely fits as in it is almost the exact size of the wheel. Makes the setup look cheap IMO. I guess I could have worded that a bit better.

And the reason the SRT comes with a 205 is just that, because there are no smaller width tires widely available for a 17" wheel. It doesn't bulge as much because BFG probably measured the tire's rated width differently than the next company. This happens with a lot of tire companies, sometimes intentionally, like with the Falken Azenis. The best way to measure a tire is with a good ol tape measure. Using manufacturer specs to determine fitment is plain ignorant.

I understand now. Its kinda hard to see another persons perspective by just reading some text on the internet. :lol:

How companies measure tires is a crap shoot. The best way to make any of their measurement info useful is to compare tires within the same company. Its the same as their UTQG ratings. There is no slandered from company to company. A Goodyear tire with a UTQG rating of 500 is completely different from a BFG tire with a UTQG of 500.

Thats why I feel tire info gets so messed up and confusing after awhile. :banghead:

Also the SRT-4 already has traction issues from the factory with its 205 tires. Image the traction problems they would have if they had 195/45/17 tires on a 250ftlbs torque steering monster!

Very true, the 205 was definitely small for the application. Should have had 225's on it from the factory with a 7" wheel IMO.

Yeah I know about the UTGQ stuff too, comparing them within the same company is indeed much more accurate.

so the best tire size to use on a non-srt neon for 17" rims like the SRT rims would be 205/45/17

but when i was reading another thread it said if you are running tokico blues and (i guess eibach spring) 205/50/17 would fit
did i read that right......

Tokico struts aren't physically different than stockers, they're just performance valved, come with sway bar tabs, and are painted blue. Lowering springs also have nothing to do with tire fitment (unless we're talking about a 3+ inch drop). So forget that info asap.

Speeder. There is only one tire that is recommended that will clear the non-SRT struts (OEM, Blues, or KYB) and fit a 6" wide wheel. That one tire is the Yokohama S. Drive in 195/45/17.

And no, Blues with Eibach springs should not be able to fit 205/50/17's. So you were misinformed. Read the very first post, after the second red sentence.

Ok after reading this sticky I have one question. Can my 205-55-17's fit on my 2002 Dodge neon SXT if I swap my struts for SRT4 struts? I jsut realized a couple days ago when i swapped my lowering springs for SRT4 springs on my non-SRT4 struts that they are rubbing the spring perch. And will I have any problems fitting SRT4 struts on my SXT?

The SRT4 struts will bolt right up to a non SRT4 neon. But Im having a hard time understanding the rest of the question. You took your non-srt lowering springs off your non-srt4 struts and installed srt springs on the non-srt struts?

Either way 205-55-17s will not fit with srt struts on the car regardless of the spring. And they will not fit with non-SRT struts. Springs dont affect the fitment of tires. Its the struts (more specifically the spring perches) that effect the choice of tires.

Yeah I forget to put some info in on that post. When I changed my springs, I also changed from 205-45-17 to 205-55-17 because the 45 is too thin, I don't like it that much. But what I read at the top was the SRT struts have a higher spring perch? is that correct? If that's true then 205-55-17 should fit with srt4 struts right? My tires are rubbing the non srt4 struts but barely. Otherwise im buying wheel spacers and pushing my tires away from the struts so they can fit. A 5mm wheel spacer should do the trick.

Ok so after reading this entire thread, I just have one question regarding the SRT4 wheels 17x6 45offset w/ 205-50-R17's - wouldn't wheel spacers (such as a 12.7mm (1/2") or maybe a little bigger like a 15mm) simply fix the rubbing of the spring perch problem for those using stock SXT suspension? It would sure be cheaper than upgrading to SRT4 struts or downgrading on tire size (205-40 / 195-45 vs. 205-50 which is still such a slim tire). I completely agree with y'all that Chrys. Daim. should of made the wheels 17x7 at a minimum. It isn't the safest idea, in terms of their corporation, to push an 8" tire on a 6" wide wheel when the recommended wheel width for a 205mm tire is 7-8" width.

Not exactly... recommended wheel width is figured not only by tire width but also how tall the sidewall is. As the sidewall gets taller the wheel width recommendation goes wider.

The SRT came with g-Force T/A KDW 205/50/17 tires. The specs for that tire in that size shows that it's recommended for a wheel width between 5.5" and 7.5" The OEM wheels are 6" so that's within spec for that tire.

To compare apples to apples lets look at the same tire, g-Force T/A KDW, but this time in a 205/40/17 size which is what would be needed to keep the speedo correct on a regular Neon. The spec for that tire shows it's recommended for a wheel width between 7" and 8"... the SRT wheel is 6" thus potentially unsafe according to the tire manufacture. This is all due to the tire side wall not being as tall.

On a SRT wheel, if you were to use a tire that was safe you'd have to run a narrower tire so you'd have to step down to a 195/45/17 which isn't exactly a normal tire size. The only tire found on Tire Rack in that size is a Yokohama S.drive and the spec for that tire show's it's recommended for a wheel width of 6" to 7.5" Again, SRT wheel is 6" so it's within the spec, thus safe.

If you run the standard SRT tire size on a regular Neon your speedo will be off by 5.9% too slow. When you're doing 60mph, you're speedo will be reading 56.5mph, a difference of 3.5mph. Since it's a percentage that gap will also widen the faster you go. At 80mph your speedo would show 75.28mph, a difference of 4.72mph.

The stock SRT wheel is also a +45mm offset, not +35mm. The SRT ACR (BBS) wheels are +40MM.

Your speedo will be off by 9.291%. When you're physically doing 60mph, your speedo will read about 54.8mph. That difference will get larger the fast you're going.
