9 inches, a 275 width tire is safe but there are some people who have gone with 285s.


Edit: found an old thread on this

If you mean the Brembo wheels, they are 9 inches wide and you can put a maximum 275/40R19 on them!

Hey Wrext, i see in your profile you have 275/40R/19's all around. How is that working for you?

I actually got them on about a week ago, so not a heck of a lot of feedback yet, but I can tell you that they do look a bit bigger and they grip a hell of a lot better than the PZero's did! Keep in mind we are at 5-10 degrees up here right now (Celsius).

The widest is a 255/45R18. I'm assuming its an 8 inch wheel here. There's not really much else out there would work on that size wheel. You are gaining nearly an inch in width, so going to a stickier tire than stock should show big improvements!

Most tire manufacturers list a 275/40R19 requiring a minimum 9 inch wheel, so while it will work on an 8.5, no one that really knows what they are doing is going to recommend it. I see a ton of warranty claims come through that could have been avoided if the retailer had just matched the proper tire to the car/driver. Many things can go wrong out on the road, why add to the chance that something will?

Really the widest you should go on an 8.5 rim is a 255/40R19. Go with a better (stickier?) tire for your needs, don't mask a cheaper tire by going wider in the wrong size for your wheel. A Michelin Supersport in a 255/40R19 will kick the crap out of the stock 245/45 Pzero Nero product for ultimate grip as it's not compromising grip for all-season performance.

This info is on any tire manufacturers website for those interested.

Edit - Always make sure your load and speed rating are correct when changes tires/sizes!

I agree. I just replaced the stock 18" wheels and 235X50X18 Pirelli PZERO Nero tires with a lighter Ford OEM wheel and Michelin 235X50X18 Pilot Super Sports. The improvement in grip is "dramatic" - the Pirelli's had 7000 miles on them of "routine" driving. More grip and less road noise. I think really good tires is probably the best "performance upgrade" you can do for a new Mustang.
