Hey guys, I have complete my rear wide body conversion and need some help on tires. Can I run a tire size 265/35/18 on a 18x8.5 56mm rim and 325/30/19 rear tire on a 19x12 rim 59mm with no issues?

Thanks

I did widebody rear only. On the front I put 275/35ZR18 tires on 18X9.5 +57 wheels and on the back I have 345/30ZR19 tires on 19X12 +59 wheels with no problems.

Shouldn't have any problems with the wheel/tire sizes you are considering.

If you are planning on adding big brakes (Z06/GS/etc) in the future, check with the wheel manufacturer to determine if there will be any clearance issues.

If you don't mind me asking where did you get the wide body kit?

Thanks! I am looking to do just the rears too, did you have any issues? Any advice before I start looking down this road?

They are all original GM parts, no fitment issues at all. You will need bigger wheels on the rear.

As a reference, the stock Grand Sport and Z06 tires and rims are as follows:
front - 18 x 9.5, 40 offset rim / 275/35-18 tire
rear - 19 x 12, 59 offset rim / 325/30-19 tire

Did you install it yourself?

Laid Back11

Yes, I did it in my garage. It took 1 1/2 hrs to remove the old panels and 2 hrs to install the new ones.

Awesome! I had heard the rear was fairly easy to do.
