Will these tuck

20X8.5, 6-5.5 lug pattern with 6" backspace

i think, IIRC, with an 18x7.5 you need like 6 or right around 6. So, Idk about an 8.5 wide

i dunno dude, i know a few guys who have 20x8.5 with 6.5 backspace that say they barely tuck, i think u might run into some problems with that backspace

anybody else? I have access for a $100 to some 20" for my Black truck? Hate to buy them if they wont fit but for a $100 it may be worth the risk.

That's cheap. I'd be all over it... For $100, you'll find out, tell the rest of the community, and if they don't fit - flip 'em for a little profit.

u may be able to get away with them if the truck isn't body dropped

Then they might have to go on the roadster! LOL

$100 twenties I'd say get them one way or another if they fit hell yeah, if not turn em.
