Default Wheel,Tire fitment question.

Ok My Brain is mush from looking at wheels and tires, do you guys think this wheel and tire would fit my truck?18x8.5 wheel size,5.5 backspacing, negative 19mm offset, with a LT325/60R18 tire? If this is way off base it's because it's 4am and my brain quit working 2hrs ago.

PS...I am adding a 2" leveling kit before the wheels and tires.

I would get a 5" BS. An 8.5" wheel for a 13" wide tire is pushing it, but can be done. I would prefer a 9" or 9.5" wheel. Your 20's are 9"w/5.75" BS and 19mm offset. Get 9"wide w/5" BS 0 offset. This will keep you out far enough for clearance but keep you in the fenders so your not sticking out 3" and will still allow you to run 35's later on if you decided to. 325/60/18 is 13" wide x 33.5" tall

OK Thanks Guys ,I just stumbled on a real good deal in that size set up thats why I asked, I'll hold out for something better,what would be Ideal in an 18" tire/wheel setup,that will fit? I want to have stock or slightly larger tires but not so large as to look like they are stuffed in there. I am going for an aggresive AT or a more tame MT. I want this thing to look like a 4wd. Will the 325/60/18 work on a wheel like you describe dog?

They will with a 5"BS. The tires are only 33.5" tall. it's the width that would be the issue. 5" BS will push them outwards 3/4" from stock. Stock tires are 10.8" wide so there's 2" diff. from the 325's and the 275's. There's guys running 305's no problem on stock 20's. Running 325/60/18's w/5" BS is actually further out from the suspension than stock 20's with 305/55's on there. .25"

One more question,Why does every online seller of tire packages only offer 31.5" tires with packages for a Ram 1500? This is very frustrating,they don't even offer the same size as stock 20s.

because 31.5" is the height of the 17's which are more common to be swapped out than stock 20's.
I would focus more on the spcs of the wheels than trying to do a search "Ram 1500 wheel combo" sort of thing. You want 5x5.5" lug pattern with the above specs already talked about. I would forget trying to get a pre-made package. Your prob better off just ordering wheels from the same place you buy tires so they can mount.balance for free and that way you can pick anything you want.
TireRack DiscountTireDirect are both good places as well as Treaddepot

Thats basically what I've been doing I just wish they would offer the combos in a 33" tire size because it seems like they offer you a little better price in a combo deal. I have looked alot at TireRack and DiscountTireDirect but I didn't know about treaddepot, Thanks again Dog!
