my brother has a 01 gmc with factory 20's and he wants a 2/4 drop he has 275/55/20 tires will they rub with the drop if so what size tires will he need? so he wont have no rub issues thanks in advance

 

I have a 2/4 drop with 275/45/20's and they dont rub. Yours are a little taller but shouldnt rub.

 

when i had 275/55 they did rub. 275/45 dont.

 

I had 275/55 on a 3/5 drop and had rubbing issues up front. switched to 275/ 45 and no issued unless I am going very fast with a huge dip in the road. I think if you went to a 255 or a bit smaller this would eliminate the the rubbing as mine was just at the edge so it was more of a width issue.

 

+1 on the 275/45s they wont rub. I'm gonna go to 255/50s when I put new tires on my truck and hope everything clears.
