I have a 2005 gmc that is having a brake issue (abs maybe) that is going to the dealer this week. I am wondering if I will have a problem since I am running the h2's & 285's. Are they going to cause problems even though I have ran for 12 months but this problem just started? Has anyone has had problems with the dealers on warranty work over wheel/tire modifications ????? thanks.

Depends on the dealer! I just went thru 1800$ in front end repairs and I run 285's I was told that they might send an inspector but if they did my dealer was going to let me know and I was going to take the truck home and swap tires back to the oem's what is your truck doing?? Z

read my posting today in "drivetrain" section. thanks...
