I think I've been reinforced on my Grabber UHP decision here...now to decide what size. Thanks for all the input guys, any more is also appreciated.

 

I don't think that you will be disappointed with the UHP's. I seriously hope that General continues to carry this tire, cause this is the best tire that I've run also, and while I've only had mine for a few months now, this will the next tire I buy again if they are still available.

 

i will be buying these again.

 

what is the widest tire i can run on a 20x8.5 rim with a 4/6 drop on a 03 silvy...front and rear without any rubbing?

 

I'd limit yourself to 265's in the rear and 245's in the front.

 

we would have to know about the back spacing on that rim too, im not very versed when it comes to this stuff but it seems like if you dont have much back spacing, you could even get some 285's to tuck up in the rear. with a 4/6 though your fronts are doing to have to be pretty low profile and not so wide like yelo said.
