2011 Mustang Tire & Wheel Clearance Question

I'm planning on getting some 2010 GT-500 wheels in 9.5 x 18 (front & rear). I was thinking of getting 285/40/18 size tires. Will this tire & wheel combo cause clearance issues with the fender or suspension system? I'm not planning on lowering the Mustang. Will I need spacers? Thanks for the replies in advance!

Do you know the offset? I have forgestar f14 18x10 rims with 42 offset and I can run 285/40r18 all around with no spacers. I just ordered another set of wheels 18x11 and will be running 315/30r18 on those. Csamsh is running 18x11rims on his Mustang and is the one that got me thinking of doing the same. Any way it comes down to the off set of the GT 500 rims

ha! treed.

Anyway- on a 9.5" wheel I'd be more comfortable with a 265/40/18.

2002 C5 Z51. MCS 2WNR TT2 coilovers, 18x11 Forgestars, 315's, yada yada. Built Z06 T56. Bolt ons. Coming soon to a CAM event near you.

2013 F150 6.2L. 9mpg.

I don't know how much the GT 500 wheels cost, but for a bigger tire look at forgestars and get 18x10.

Those wheels are $165 a piece and come originally on the 2010 GT500 convertible. They OE Tire Size is 255/45/18 front and 285/35/18 rear.

Having said that, 285 is absolutely OK, as FORD put those on from the factory. I have those as my winter set (although 255/45/18 all around)

285/35/18 is 657 mm in diameter
255/45/18 is 687 mm in diameter
285/40/18 is 685 mm in diameter

No spacers needed. If you want 285/40 all around you want to look closely up front for rubbing. I would go with the OE sizes, as those won't give you any issues.

Thanks! - All good information! I don't know what the off-set is of the GT500 wheels. The reason I picked 285/40/18 is because the change in the speedometer is negligible (.75 to 1 mph difference) between the stock OE tires (235/50/18) and the bigger tires. If the OE tire up front for the 2010 GT500 is 255/45/18...there will probably be clearance problems with a 285/40/18. (my thoughts).

When i look at my fronts (slightly lowered .75") there should be room for wider tires. Some folks are running 275's up front... so it might be worth a try, if you don't want to go staggered..
At least those rims clear the 4piston Brembo's....

I don't think I'll have clearance problems with my brakes. They're the standard brakes, not Brembos. I would like to have the same size tires all the way around so that I can rotate them as necessary. I'll have to check on the 275's! Thanks for the feedback!
