Howdy again<p>I was driving my car on a track today and my stock tyres really sucked. So, is it just about the tyres or the size too? <p>I have pirelli p7 205/55/16 <p>Can i put like 225/45/16 tyres on the stock 16" rims?<p>cheers
It's probably a combination of the type of tyre and its size.<p>225/45R16 would give you a different rolling radius from the stock size. If you want to go with 225 then you'll need to use 225/50R16. But if you put that on the stock rims then there'll be a noticeable tire bulge. The bulge is fine for day to day driving, but I'm not sure how well they'll do on the track.
Either way, our stockies suck big time. I took mine (MichelinMX4, 205, 17") to the auto-cross track the other weekend and it was sliding back and forth, left and right all the way. Wheel spin, steer torque, understeer - you name it, I got it. I was able to come first in last 5 (out of 40 cars mind you). At least I beat Acura RSX for almost 20 secs and an M3 for .5

the stock 16 x 6.5 will accept several sizes but to keep within the stock rolling diameter,(highly recommended) I'd stick to the 205 55 16 or go to a 225 50 16. if you like tire to fender gap a 205 40 16 will also fit.
its not so much the rim size... i know lots of people who run 16 inch rims for track because of the weight saving... but more your tires.<p>stock P7s, just dont cut it on the track. if you want to do well, make sure you get some good track tires or road legal semi slicks.
