Tire Question

Post by boostalot717 » Mon Jun 27, 2011 10:08 am

I am no wheel and tire expert by any means. I read the sticky above and it says that a 205 will fit on a 17" +40 offset wheel. But I recall others running wider tires. Here is what I am looking to get and hopefully someone can say if it will fit with stock struts. 17x7.5 +40 offset with a 225/40/17 tire. Sorry for the stupid question don't know much about putting bigger wheels on a car.

You need to know what the width of the wheel is, not the offset, to determine how wide a tire you can safely install. Aspect ratio will also affect how wide you can go.
If I could just figure out how to meld the Outback and the Neon into one car...

Wheel is 7.5" wide so a 225/40 would fit safely. I am just unsure it would clear the struts and the tension rods in the rear.

If I remember correctly someone was running a 225/50 on a 16" rim. So seemingly I should be able to run the same width tire on a 17" rim with a shorter sidewall.

I run a 225/40/17 hooiser on a 17x7.7 +40 offset wheel

A 7.5" wheel with the same offset as stock (+40) would add 3/4" of width to both sides compared to stock. Measure the widest part of your stock wheel/tire assembly to the struts and tension struts, and see how much width you can play with. Off the top of my head I would bet that it won't work, but you can check for yourself.

A 225 width tire is 9" wide in theory, though they are usually closer to 8" in reality. For example, my 215 Kumho XS are only around 7.75" as measured by hand, yet 215mm converts to 8.45" (quite a difference). Having said that, use the first numbers I gave above and measure for clearance. Height fitment issues can be addressed with a thinner sidewall tire, but width clearance, unless using wheel spacers, is non adjustable. You can gain clearance with a lower offset, but with the risk of fender clearance issues.
