You read on these forums people with 22"s that have 305/45R22 tires... some rub some dont and people say if you have the correct offset you are fine, so what exactly is the correct offset??

If you rub with the 305/45 series, just go down to the 285/45 series tire. You should have the installer check before taking your Escalade off the rack. Make the adjustments (fender cutting, plastic trimming). Then go ahead with your proper setting for the tires not to rub and it's a done deal. OBS lades have bigger wheel wells than the 02+ models though. The 07 look like they have an even smaller wheel well. Wonder if you can roll the rear windows down all the way now?

Offset is the distance from the mounting face of the wheel (the side that touches the brake drum/rotor) to the centerline of the rim/tire. For most autos & light truck wheels the centerline of the tire is inboard of the mounting face. The offset positions the tire in the wheel well of the vehicle. So a different offset moves the tire in or out.

You don't want to use an offset different than what the manufacturer specifies. The vehicle is set up based on the design offset. Bearing loading/life is affected. Steering and stability during braking is affected. Translated - void warranty and potential liability in an accident if you use a different offset than the design offset.

I guess im confused here... So what does the escalade specify as the correct offset?

The GM offset for most of the 6 bolt on 5.5" BC, including the Escalade, is 31mm inset or 1.22". There are some Chevy & GMC trucks that use 41mm, but the Escalade is listed at 31mm.
