Default HPtuners gear/tire wizard issue
Trying to auto scale a gen iv Suburban for 35" tires... but on the gear tire wizard it's showing a final drive of 1.00 and a tire size of 6.12. All of my Gen 4 suv stock tunes are showing the same, where the trucks are showing up normal.

Are you running the latest software update? One of the previous version had some errors with that.

Yes, that was my first step. 3.6 didn't fix it.

I would contact support to see what they can do.

Put in 6.6938 for tire size and it should get you close.

Contacted support but no word from them yet. I tried to put 7.00 in for tire size and it said it was invalid. I just manually added 9%- for now
