275/45/20. Found some for cheap but not sure if they rub or not with it being lowered 4/6.

 

Perfect size for a 4/6, I had them on mine and numerous others run these as well.

 

Think personally its a bit big...is it a crew cab?

i ran 275/40r20

 

i would personally go with the 275/40. when the suspension settles a 45 series will probably rub. just my .02c

 

Are you running stock 20's or aftermarket?

 

Mine rub in the front if I hit a decent dip in the road. They do not rub at all lock to lock though... my next set will be 275/40/20's

 

On my nnbs 4/6 dropped with 275 45s it dont rub at all

 

i ran that size for a year or so. they work really good the only time i had an issue was at high speeds if you hit a dip in the rad my front tires did bottom out. i just changed a couple of weeks ago to a 275/40/20 good looking tire size and no rub

 

It's just a reg cab. Those 45's I found for cheap sold 15 mins before I got there. But that works cause I'll prolly go with the 40's everyone likes.
