Trying to look at a wheel and tire combo and trying to figure out if I can run a 305/50VR20 tire at all 4 corners without having any issues of rubbing. The wheels will probably be a 20x9.5". Also planning to go with the hotchkis tvs system. If this size won't work, what other sizes could I run to still have a fairly beefy tire under the truck? Keep in mind that I need a size that the BFG KDWS comes in.

 

305 is 12" that might be a little to wide for the front

 

Is that hotchkis kit gonna lower it ??

 

How much is it going to be lowered?

I don't think you would be happy running the 305's on the front - they will stick out and I think you would also have many clearance problems. You could get away with it on the back, but I'm not sure how well they will work on a lowered truck, considering this tire is 2" taller than stock (assuming you have 2wd)

After much research, my plans are to run:
Front: BFG KDW 265/50/20 20x8.5 w/6" backspace
Rear: BFG KDW 295/45/20 20x10 w/7" backspace.

This combo will work nicely with 2/4 drop or as stock. If you wanted a 4/6 drop, a 7.5" BS in the rear would be preferable.
