i have a 2008 dodge ram 1500 4x4 and i was wondering if some 20 in boss rims witn +14mm backspacing and some 305-55-20 nitto trail grapplers would fit with a 2.5 in levelin kit?

 

You should have no problems. I believe the backspacing should be good to clear a 12" wide tire. And it seems to be about a 33" tire which actually came factory on the 20" rims.

 

does the backspacing mean they will stick out a lil ordoes it mean they will beflush, i want them to stick out a lil bit

 

Negative offset will push the tire out, positive will sit more into the wheel well. You may have a bit of a problem with that wheel and your control arm hitting.

Do you go off road at all? You are not going to have much flex or much sidewall with a 33" tire on a 20" wheel. You can forget airing down much...

 

the most offroading i do is going to my deer lease which can get pretty rough and nasty, what would be the best back spacing that you would perfer, im either goin with 33 or 35 terra grapplers

 

Personally, I think 35s are too stuffed with just a level, even though they fit, there ain't much room for "nasty". Also, nobody who seriously drives off road does it on 20" wheels unless the tires are around 37" or taller. You have way too little sidewall. Off-road, it's all about flex and floatation and with no sidewall, you have neither.

On a 4x4, 20" or larger tires is a "looks" thing and a detriment to performance. If I could fit 'em around the calipers, I'd have 15" wheels...

 

so wat offset would you perfer for a 33 in tire and some rims, does my truck have enough power to turn 33 mud grapplers

 

would these rims fit on my truck with 33 terra or mud grapplers and a 2.5 inch level, +30mm Offset, and 6.18" Backspace these are moto metal 951 chrome edition

 

I'm thinking +14mm might cause some clearance issues.

 

You ideally want between 4.25" and 4.75" backspacing with a 0 or negative offset especially for an A/T or M/T tire...
