Bump!

I'm planning on buying wheels on saturday.

Is a 30/9.5 tire going to rub on a wheel with 4.5 inches of backspacing as opposed to the factory 6 inches?!?!?!

if 6" doesnt rub why would 4.5"? what offset negative or postive?

A 30x9.5/15 is the biggest tire you can fit on the dime with zero rub. increase the size increase the rub risk.

less backspacing = wheel/tire sticks out more.

I'm worried about the front tire rubbing on the fender when I turn.

Great post mdnky.

A 30" tire is only 1" bigger then stock 235/75R15 tires, thats a whole 1/2" per side. IF the tires are really 30" and not 29.5" which is typical. Not every tire is exactly the size listed. Check the manufacture. I'll use the BFG All-Terrian tires for example. The 30" tire is actually 29.5" in diameter. And the 235/75R15 is 29" in diameter. That's a whole 1/4" diference per side.
BFG KO sizes

4.5" backspacing and 30" tires would be close. Real close. But I think you'll be fine with that set-up. You might end up doing a slight-bar crank, but nothing major.

Great! Thanks Hanr3. 15x8 with 4.5 inches of backspacing and 30/9.5 is what I'll go with.

KO's blow, 1 season on the ram and they have 25% treadlife left and its mainly a highway vehicle.

Id shop around for tires, I wouldnt put any BFG on my vehicles except the radial T/A because they last forever.

Just what ive experiences, Im going to run General Grabber AT/2's and If i dont like those its Nitto terragrapplers.

Well I was planning on going with BFG mud terrain, but I think I might try out the Hercules Durango MT.

They look decent and they are about $40 less per tire than the BFG.

Detroit muscle you need to control how you drive, properly inflate your tires or get an alignment. I've gotten 80k on my BFG AT KO on my durango and I'm finally about ready to change them. The truck has done everything from running down trails in the woods to highway to city to dirt road driving.

Kellen - I have the BFG mud terrains on my blazer now 30x9.5 on stock wheels. They fit perfect and they are the best mud tire I have ever purchased. Incredable amount of grip in dry, muddy snowy conditions. They only thing they really lack were wet traction. After I realized that I went back and spent an extra $30 bucks to have them siped and now they are pretty much perfect tires in any condition. I've yet to have them on ice yet but we'll see in the near future here :)
