Those tire will look very lowrider in my opinion.
The rears (295/35/18)will be 1.05 inches shorter than stock and the fronts (255/35/18_will be 2.15 inches shorter than stock.
That will affect speedometer, final drive gear ratio and top speed. It will also look out of proportion with the front tire having such a short profile.
Did you research the tire height before choosing this size tire?
2006 Mustang GT Prem Vert
Kenne Bell 2.4 w/Intercooler @ 10 PSI
Level 10 Stage II transmission
Billett 3300 RPM Stall speed from Level 10
Ah! Research. Could you define that for me kopfjager, `cause I don't want to look it up. [sm=icon_rofl.gif]
Sorry, I couldn't help myself...
Ok, I could, but I'm having too much fun with the smileys today.
Seriously though, the Michelin Pilot Sport PS2's come in 255/40 and 275/40 sizes. That's what you had in mind, no. But the 255/40s are going to be 1 1/4" shorter than stock 235/50s...so you have a significant speedo error (5%), and possibly (I hear) problems with your antilock brakes acting up. Scratch that--the difference between the stock and 255/40s might cause a problem, but the difference between 255/40s and 275/40s is about 1/2" in height, so that may not be enough to freak out the antilock processor.
Actually, you guys seem to be comparing apples to oranges. If the stockers are 235/55 17's as they were on mine. You can go to a 255/45 18 as I did and all your speedo etc. will be the same as the actual circumference of the tire will stay the same. Just go to tirerack.com and look at revolutions per mile for your tire sizes in question and make sure they are similar or you will have those issues. And of course a programmer will solve the speedo issue if you decide on a different circumference. Dunno about the antilocks though.
As far as the rubbing goes, I haven't had a rub yet, but then again, 255's are a mile away from 315's, so you're on your own there.
