325/30/21 tires and "4WD overheat" issue

[ardg12]

Hello Everyone,

I have aftermarket Signature wheels on the H, with 20/21 setup. Time came for change in rear tires and now I had this issue as I was driving home from the tire shop.....

Prior set up on the rear was 325/25/21, no 4wd issues, and overall the car drove great.

I decided to try 325/30/21 Michelin P....the car was skidding, the EPS keep blinking on the dash....then on the highway I got the 4WD overheat issue. I had never seen this before....

Any recommenations? I know the tire shop overinflated te tires a bit to 3.0 PSI, so I am going to bring that down a bit, but I dont think that is the problem....

1” to large diameter in the rear. I’d like to see pictures honestly. What is the size of the front tires?

Did you ever figure out the issue and the solution?
