sube151 · 05-11-2001, 07:57 AM

Guys/Gals,

I have the 17" gold wrx wheels and need to know if I can run a 215/40/17 instead of
a 215/45/17.

Will it rub, is it bad???? Pros...cons??

Help me please

The 40 series will be smaller diameter, so less chance of rubbing with the 40.

However, smaller tire = greater speedometer and odometer error. (45 is just about the same as stock - a 40 will make your speedo read about 4.4% too fast) There is also a little less sidewall to absorb impacts, so a slightly greater chance of dinging a wheel.

Upsides can be a little better response from the tire, and a little improvement in acceleration from the gearing change. (Tires are gears too)

In the future please post this kind of thing in the appropriate forum, no problems getting help there

Kelly,

Thank you very much for your detailed answer. Very sorry about posting here

I just had to make a quick decession.

Do you think the tire will look to thin on the WRX(sidewall)?
