Front Wheels are 19x8.5 w/+20 offset and rear are 19x10 w/+19 offset.

 

Do not check the OEM tire width for a 8.5-inch wheel. Do not check the tire forum and see what width members are running on a 10-inch wheel.
Do not use a tire calculator to compare the OEM tire heights to your set-up.
Do not check the overall tire height to insure proper operation of VDC.

Let someone do it for your.

 

loll ^ exactly wat i woulda done

 

I would go with 245/35 and 295/30

BUT

With that rear offset Your rears would probably rub if lowered, so you would have to probably go with a 285 or 275.

245/35 and 275/35 would work but your rears might be stretched a little more than the front.

 

I'd say 245/35 and a 285/35. And with that tire size and offset, you can easily sport a 1" drop (fenders rolled) and -1 camber.
