bimmertech said:the middle number is the aspect ratio. it is a percentage of how wide the tire is, pretty much says how tall the sidewall is. 275 is max i would go on a 9in wheel. anything else will hang over the edge and look gay. what kind of wheels do you have?
they are 17x9, and i wouldn't get 265...just get a set of 275/40/17 kuhmo ecsta supras....my buddy had em on his 98 gt and loved emSynned said:I have 03 cobras i'm pretty sure that they are 17x9.5. Should I go with like 265/45/17
I dont want that tall of a tire cause i dont want decreased acceleration lol.

yea bimmer seems to know his **** about suspension/tires and such because i get the feeling hes into auto-x type racing....right on man!!!bimmertech said:
that seems to be the norm on 17x9's. although ford puts 255's on a 17x9(95 cobra r's) 275's on the 03/04 cobra, and 265's on a 18x9.5(00 cobra r). as with all factory stuff there is always room for improvement.
wordSeventyMach1 said:BTW, you can't base the sidewall height strictly on the "middle number". Depending on the width of the tires compared, a "higher" number doesn't always indicate a "taller" tire. As bimmer mentioned previously, it is a percentage. Hope that will help in your decision.
