I’ve recently installed a 2.5 inch lift and 255-75-17 tires.
So I cobbled together this 14 inch tall block to drive up and test suspension flex and tire clearance.



This is pretty much full stuff. Tire isn’t quite hitting the plastic but there isn’t much more room.

Do you have extended bump stops? When I did this with my 265/70r16 duratracs they were catching on the inside of the rear fender flare where it tucks into the wheel well with one hockey puck. I cut off about a half inch of the flare inside the wheel well and it seems to clear the tire but it’s darn close.

I have two hockey pucks per side.
I didn’t look to see if the bump stops were touching but I don’t think they were.
I kinda think I should have gone with three pucks per side.
