Wheel rub on Chevy express with 33" tires

You may be able to find out with your VIN # as well. If your local dealership is cool they can probably give you the full detail using that.

Or just slap it all together and let’er eat?

Welcome.

I reprogrammed the computer for the tire size with a Hypertech speedometer calibrator.

The low rpm in 6th will also be impacted by the trans gear. I assume you could find out through a dealer with the VIN. Edit: I see Whit commented on the dealer as well.
