17's on an R/T

nerox · Post by **nerox** » Sun Jan 30, 2011 1:16 pm

i have an '01 R/T (BUX) with standard silverstones and normal 195/50/16 tyres.

my wheels and tyres are in poor condition and rather than paying loads to get them refurbed and new tyres i'm looking at getting some fresh wheels - 17"s

as far as my research shows 215/40/17 is close as makes no difference to exactly the same size as standard 195/50/16 regards the diameter of the tyre.

i have the car lowered 35mm on SPAX springs with stock struts. i'm looking into BC coilovers eventually but not yet.

just checking that 215/40/17s won't foul on the spring rest or anything else due to the increased width of the tyre and i wont need fenders rolled?

and also ... what offset do i shop for? the guy in my local wheel shop says anything between 35 and 45.

the wheels i am looking at specifically are 38 offset and 7.5 wide

i'd just like to check this is accurate with you guys who know better than him ... and me!

You would have no issues with that set up. The tires would clear the struts perfectly and would not have any contact with your front fenders.

i've found a guy who can wheel refurb pretty cheap so i think im gonna keep my standards for now.

the problem is that the standar tyre size of 195/50/16 has poor selection of tyres.

205/45/16 and 205/50/16 are also expensive however ... 205/55/16 have a MASSIVE collection and much better prices.

will fitting 4 of these 205/55/16 cause any problems on standard r/t rims ?

Won't cause issues with your rims, it will however likely cause issues with suspension interference however. As well, your speedometer will not read correctly at all...

oh i see, yeah i forgot about the speedo issue.

its annoying because the tyres in standard size 195/50/16 are a lot more expensive than slightly different sizes in the same brand.

and also i'd like to go a bit wider on the tyre in hope of more grip

what about going for 205/50/16.

the calculator says it has only 10mm difference in diameter to standard and "at 70mph your speedo will read 71.16mph"

I'm running 205/55/16s
Stock struts with eibach springs.
No clearance issues.
Never have checked my speedometer though...can't imagine it's off by that much.

With the 205/55, your speedo is off by over 5%.

205/50 would work ok.

Interesting... O.o
I may or may not be worried about this.
