265/70/17 Duratrac's rubbing...

So i recently got a set of 265/70/17 duratrac's mounted on some Ion rims, I thought they were gonna fit no problem but it seems im having some rubbing issues on the passenger side mud flap
Anyone else had this issue?

 

Same tires on sport stockers...no rubbin!

 

What backspacing do those ION wheels have? That sucks...I want to get some. Hopefully my 2.5" lift will fix that.

 

most people take the front flaps off when going up to 265/75 16s or 265/70 17s

i had to

 

I think the backspacing is 4.5? not 100% sure though. It looks like its just a little trim to take care of it

 

My 265/75/16 Duratracs rubbed a bit on my front mud flaps. Easy fix...take them off! Looks better without the fronts IMO anyways.

 

Haha yea im gonna try and trim the nub on the inside and see if that fixes it if not looks like they will be going, id like to try and keep em though

 

I'm running 265/70/17 (originals were 265/65/17 Dunlops) and have no rubbing issues on stock rims with 3" lift.

 

not even on the mud flaps??? my tires ate my mudflaps... so if you plan on offroading ditch em or the tires will for you

 

Same problem here. My rims got 4.5 bs and i was still rubbing on the mudflaps. Easy solution tho, take 'em off! Or lift it, that should help too.

 

I took the mudflaps off and all is good, i still want to run a set im gonna look at som aftermarket ones of trim the stockers down and holesaw out the problem spots

 

I have 265/70-17 REVO's on my truck, and even before my lift they didn't rub...not even close. Must be the 4.5 backspacing that's making the difference. Must be time for some 5100's

 

I wonder if the .85 setting would be enough or even the 1.5 should level it out without doing anything to the ass end
