I found wheels and tires online and would like some information about them.

The wheels are Ultra Wheels Goliath Chrome 18" x 10" (looks like a solid chrome wheel with small curved bellies in the outer rim)

Description says "chrome plated" -- what's this and does it last? I won't be driving these in the winter.

The tires are the Nitto Terra Grapplers 325/60/18". Anyone use these? How do they hold up? The specs say these are 33.2" tall x 13" wide. Will these fit well under my 2004 dodge ram with a 2" lift?

 

They will fit, but because they're 10" wide they might rub just a little bit. My 33s did on 20x10s. Not a big deal to fix though, just a little trimming.

 

the tires should fit under your truck. they are the metric equivalent of a 33x12.50 just make sure that the rims have the proper amount of negative offset so you dont interfere with stuff under the truck like frame members, steering linkages or brake lines.
any chrome rim is "chrome plated" it just means that the rim is an alloy and the chrome is electronically adhered to it.
if you plan to use the truck offroad alot you may want to go to a smaller wheel size because the larger the rim the easier it is to knock the bead off

 

What is proper negative offset? How much?

 

Im not sure for your truck but probably at least 5 inches. measure how far from the bolt face of the rim your rim goes back in toward the truck and dont let the new rim go farther in than that. if your rim goes in 4 inches then you need a 10 inch rim with 6 inches of negative offset. also mounting a 13 inch tire on a 10 inch rim is going to be difficult and will make you run on the center of the tire. ideally your tread width should be the same as your rim width

 

The 18" x 10" Ultra Wheels have a 25mm offset and a 4.52 backspace. So this is saying it has about 4.5" from the bolt face to the backside of the rim?

Also, I went back and looked up the tire specs. The tire spec says they work on 9.5" to 12" rims. Do you suggest I go with a 9.5" wheel and smaller tire to avoid rubbing issues? Too bad if that's the case, the wheels come 10" only.

 

with a 10" wide wheel, 4.5" b/s, and that tire, i think you will be looking at rubbing the rear of the fender well in front.

 

a leveling kit is around $100 bucks and they do just fine if you dont hardcore off road your truck. ive had 2 leveling kits and had no issues. the terra grappler is a good tire and so is the toyo open country that looks just like it

 

The wheel company said the wheel/tire would stick out 3" from the fender and more than likely rub. With a 2" leveling kit they still thought it would rub. Too bad. I liked those wheels.

They only come one size!

Guess I'll go with Helo 18x9.
