    Power running boards and 26" rims?

    I think I read something on here years ago about problems with 26" rims on escalade's with power running boards but I can't seem to find anything now. So, are we able to safely ride on 26" rims without rubbing or do we need to make any modifications? Also, does anyone know what the safe offset/backspace is for 26x10 rims?

    Thanks in advance.

    30 to 35 offset. There are Allen bolts you can loosen to slide the boards for clearance.

    Mine still rub like hell on the running boards. I'll check that out about the Allen bolts though.......

    Thanks prosseda.

    If there would be any rubbing, where would it usually take place? Front or rear?

    What are the problems in running a lower offset like around +10-15mm?

    My factory 22 rubbed the inner fenders on mine when I picked it up.

    They rub in the front when you turn the wheel. It actually ended up rubbing some of the running board off.

    The lower offset makes the arc the tire pivots on longer. So then the tire can rub with even less steering angle. If a 30 offset just clears the inner fender, imagine a 15 trying to compress your tire that extra 15mm by using your inner fender. A properly inflated tire doesn't even compress that much with the weight of the vehicle on it. So you would end up with the complete force of your power steering pushing on your fender.

    The size of rims I'm looking at only comes in a 26x10 with a +25mm offset. 305/30 tires. I was playing around measuring earlier and am pretty confident I will have rubbing issues with the running boards. Will I have issues with the inner fenders? If so, is there anything I can do to prevent it?

    I know a sawzall will work for that! I had 35" tires on my H3t and I ran into the problem of them rubbing the inner fender. I took a sawzall to them and fixed the problem. I know my stock 22's are close to rubbing when I lock the steering to the right. But if you get the right size tire and offset, there should be no issues. If the new tires sit taller than the stocks, they will rub when you make a sharp enough turn.

    Guess I'll find out once I get the rims mounted...I can live without turning the wheel all the way, but having the running boards hit on a light turns is a different story.

    The power running boards are adjustable to move back. I'm not sure if they were on all years, but I just picked up my 2012 and the dealer moved the power boards back for me so the 26s wouldn't rub. I'm running 295 width tires though and I have a 2/3 drop and it doesn't rub at all. Only when I crank it in reverse it will rub on the plastic inner fender wall. When I had my Denali it rubbed there too with the same set up, but after a couple months it stopped because the tired rubbed away the plastic. I haven't had any problems with it regarding the running boards though.
