Need some help / advice so I don't screw this up... Going to buy some ADV 5.0 Track Specs, need to make sure everything is correct...

Tires - Tires seem to dictate what rims you can use, and what I've settled on is some Vredsteins. Comared to stock, here's what comes up...

=====STOCK==== Diam Width Sidewall
Front 275 40 20 28.7 10.8 4.3
Rear 315 35 20 28.7 12.4 4.3

=====NEW==== Diam Width Sidewall
Front 265 35 22 29.3 10.4 3.6
Rear 315 30 22 29.4 12.4 3.7

Will having a slight .1 inch difference between front and rear diameter cause issues with the AWD and traction control?????

The overall diameter is an extra .6/.7 inches taller than stock, which I like with the 22's since the extra sidewall will protect the tims better. But, how much will this throw off my speedo? Can it be corrected by the dealer? Will this totally screw up performance?

Next question: Can I put on 22x10 for the front and 22x12 in the rear since the tires will be wider than the rims? Is .4 cutting it too close?

Last question, I'm familiar with dealing with offset as my "other" vehicle is a heavily modified Jeep Rubicon 4 dr, but do you guys deal with offset? If so, what is standard / stock offset and what would be the cooresponding offset if I wanted to use these rim dimensions and go to the new wheel dimensions listed above?

THANK YOU FOR SPENDING THE TIME TO HELP!
