Hey guys I have a new set of 20 x 8.5 rock stars and looking to put a new set of rubber for the summer. I also have a rough country 2.5" front and 1.75" level kit going in this week. I am looking to fill in the wheel well with a good a/t tire. What is the biggest I can get without rubbing issues.

2012 ramm 1500 crew cab

Rim specs:
Wheel Part Number: XD77528586310
Size: 20 x 8.5
Diameter: 20
Width: 8.5
Lug Count: 5
Bolt Pattern: 5X5.5/150
Metric Bolt Pattern: 5x139.7/5x150
Offset: 10
Backspacing: 5.14
Center Bore: 110.5


Thanks.

If its plus 10 it depend on height or width. A 285/ 65 will fit or a 295/60 or 65 should be good with that offset or a 305/55.

I had the BFG AT KO's 285/65r20 for a while and they are a great, long lasting tire. I just wanted to go bigger!

For an AT tire, I would look into the new Toyo AT2. Then I would look into BFG or Nitto Terra.
There are many others, but named the more common ones.

Because you have an 8.5" wide rim you are slightly better off than those with 9" wide rim
you actually have 3mm more to play with.

But I do not see why at 35" tire wont fit given you level the front a minimum of 2.5"

I'd also recommend getting some hub rings to make them snug on the hub of the truck :smileup:

Looked at the toyo at 2 but they don't make it in a 285/65r20 but they do have it in a 305/55r20 according to the site though they recommend a 9.5" rim width. Also I called 4 wheel parts about ordering a hub ring but they said I didn't need one due to that the dodges are the only truck using a 5 by 5.5 bolt pattern.

After calling about 20 local places and checking pretty much every website online I came across a place in BC that will ship to Newfoundland for free. I can 35 x 12.5 toyo open country at2 for $1700 taxes in. Best deal I can find and cheaper than the local stores are selling the bfg's at a smaller size.
