I've got 17x9 04 Cobra rims all around on my 96 Cobra. I currently have 275/40/17 Hankook tires all around. I'm needing 2 new tires. I'm gonna go with Nitto 555's, I'm just not sure on the sizes. I'd really like a narrower tire up from to help with handling. I can buy 2 275/40's and then decide where to put them. I like this idea because I can rotate and also they are almost the same diameter as stock so my speedometer won't be thrown off. However, I'm really considering 255/40's up front with a 275 or 285/40 out back. If I did this, I'd just buy the 2 fronts now, use the 275 Hankooks, then when the time came get the rear's (really thinking 285, but they'll be a little taller than stock so not sure how that'll effect me). It's a daily driver, I only see the track 2-3 times a year so I'm mainly going for daily performance. Any suggestions on which setup? Any downsides to going 285/40 on the rear? How will the shorter tire up front look with a taller one out back? Thanks!
