i don't think that 265 is the recommended size, cobras came with 245's i think 255's r the ideal strate wall size.yes 265 is the reccomended size for an 9" wide rim. 265/35 will clear fine with no rubbing
trust me 265's are reccomended for a 9" wide rim. check out AM and it will even tell you that. you can put 275's but if the car is lowered it will most likely rub. go with 265's thats what im going withok well im not positive, but i know ford put 245's on 9in rims on some recent mustang.
id defenataly go wider in the front, 235 is starting to strech the tire. 245 or 255 would be better. u also my want to look for somthing a little bit bigger as well, like at least 295ok i dont have alot of power to spin them i just want a nice lookin tire tire rack said that 235/45/17 for the front will work and i was thinkin 275/40/17 for the rear
