...just curious...are you sure that the wheels are staggered (rear wheels are wider than front)? Perhaps all the tires are the same size because the wheels are also all the same size.

:worthless:

I havent measured them but they look different with different offsets...two are more concave when you look at them from street side.

lol...will try to get some tomorrow.....

275 40 on the rear is fine. It's sized accordingly and depending on the *tire brand*, should be speced to fit the 10.5. It WILL look a lil stretched...but for all intents and purposes, the sizing is fine

the tires actually are 275 45 20...

they are NOT factory if the tires on the rear wheels look fine. they would be a small tire for that wide wheel.

Truth.

Stock wheels are staggered in size.

I had 275/45/R20 on all four 9.5" wide rims (non staggered) without any major issues (except minor speedo and odometer difference from stock rotating diameter). Extra side wall was nice around city roads!
