My 2019 Bullitt has different size front and rear tires

First of all this must be a commonly known situation, but I couldn't find any thing on the forum search about it. My 2019 Bullitt has 255-40 ZR 19 front and 275-40 ZR 19 rears. What is the advantage to this? Are the wheels different sizes as well? Could I put the same size tires on all 4 wheels when it comes time for replacement? With the expensive rubber this car requires, I'd like to have the additional tire mileage that I might get from tire rotation. Other than an occasional track run, this car will be driven on roads in the U.S.

I'm pretty sure they have been doing that on the performance pack cars for a few years.

And I am not sure, but I think the wheels are 19x9.5 on all four corners. This should be listed in the literature somewhere, maybe on your window sticker; worst case, you can pull off a front and rear wheel and check the stamping on the back.

If so, yes you can run the same tires all around . . . if you want to save some money you could use the 255's all around but you'll lose some traction in the back; or 275's all around would be preferred for road track. Some tires are also available in 265/40 so that would be another choice (relatively limited options from as I recall)

The wider rear tires are for better traction. 275's on all four corners shouldn't be a problem though.

unfortunately this does not list the wheel widths, which is what you need to know for tire sizing/fitment . . . the fall-back approach to find out the width, is to take the wheel off the car and look at the back of it

Yeah totally normal. You have the same staggered setup as a performance package GT just with the old school Heritage style wheels. You get to have better traction with this setup, if you ever tried launching a base spec Mustang GT, you would appreciate the staggered tires.

As others have stated this is 100% normal and nothing to worry about. It is actually preffered setup for performance cars. My wife family never understands because like you they want to rotate and change tires less often. I didn't buy the car to save money on gas, tires, and things like that I bought the car to have fun. I tell people if they car about gas mileage, tire cost/low life of tires, and things like that they may be looking at the wrong car to buy. haha

Congrats on your Bullitt though and hope you enjoy the car and it sees some road miles and not all garage time like many specialty Mustangs and cars go to live. I am a full believer of driving the cars I buy and not saving them for the next owner. haha

thanks Pete -- now that we know that, we can answer the earlier question --

yes, you can put the same tires on all four corners, but it will be a little weird since the front and rear wheels are different; and tire rotation will be limited because you really don't want the 9.5" wheels on the front . . . if the tires are not directional, you can rotate the tires side-to-side, but not front-to-back

personally I think tire rotation is over-rated anyway; there is no law of man or nature that says you have to replace all 4 tires at the same time; you can just replace in pairs when they wear out

Thanks for the info. Although the car is on stands now, in Wisconsin, my intention is to drive it. I think I'll stay with the current setup as far as wheels go. Thanks for all the kind responses, but I fell in love with Mustangs late in life and have a lot to learn!
