I have a 3" levelling kit and i want to put 35x12.5x17 on my 2003 SRW diesel quad cab will i have enough clearance? I read some where i may need another inch clearance.

 

Can't give you a definite answer, but I suspect you will need more lift. I have the 2003 2500 SLT Quad Cab 4x4 with a 4.5 inch lift and 35x12.5x18 tires. On sharp turns, the front wheels rub & cracked the cowling under the front bumper by the wheel well. I trimmed off the cowling & haven't had a problem since. I think the front tires also come very close to the back part of the wheel well on sharp turns. Not sure if you could trim off enough cowling to make clearance in the front & I'd be a little concerned about the wheel well clearance on the back side of the wheel.

Like I said, not a definitive answer, but at least you know what the extra 1.5 inches does for me....

 

i have a 2003 1500 that clears 315 BFG All Terrains with out a lift.
