I have a 2007 with completly stock hieght, suspension and wheels. I read that changing the width of the tires will effect the VSA.
Any truth to that? What size tires can I go with if I am looking for a wider contack patch? I do not want to change anything from stock except the tire width.
Any recommendation on tires? I have no intension of doing track days.

 

Just do a 255 in the rear. That's as wide as you can go. Fronts leave at 215. If these sizes are ok on the CR I would expect them to be fine on an 06+ Ap2.

 

i run 245/40 on 17x9+45 all around & dont have a problem
i have friends who run 255/40 square on 17x9+45 or 17x10 & vsa hasnt been an issue for all of them
& yes these are all on 06+ years

 

I have an 07 as well and run 225/45 f and 255/40 r...no issues here

 

Thanks for the feedback.

 

225/255 street
VSA on no issues
255 square track
VSA off

 

Tire width should not be an issue. The problem comes with tire diameter. front and rear tires have to be close in diameter, otherwise the different tire revolution speeds will confuse the VSA system.

 

I see . So going to an 18"wheel would be a problem?

 

It will not be a problem if the TIRE DIAMETER is kept consistent, meaning that the tires must be sized properly. e.g., 255/35/18 and 255/40/17 have the same diameter.
