Can I run 35's?

oland · May 23, 2017

Need some help here, currently run stock 20 in Ram wheel with a 3 inch level front and 2 in rear. Want to buy set of Nitto ridge grappler's in 35x12.50x20 and run them on the stock ram wheels 20x8.

Can someone tell me what/if i need spacers, will the 35's even fit on that wheel? I ask 20 people, i get 20 different answers...Thanks!

I have a 4" lift and am running a 34" tire on stock rims. I have rubbing on tight turns. I think you will need spacers

I just installed a 3" leveling kit on my 13 Ram and put 35 12.50 20 Toyo open country mt on it. I have no rubbing or scrub at full lock even backing out of my drive way which has a bad dip in it. I clear them perfectly fine.

Not to add more confusion, but a lot will depend on the "actual size" of the tires. When I got my truck, it had 35x12.50-20's on the factory rims. Even with 1/4" spacers, they still rubbed when turned all the way. My second set of tires were also "advertised" as 33x12.50-20's, but they measured slightly less than 12.5" wide. The second set did not run quite as bad.

Width is the bigger concern. Just grab some 1/4" spacers and use them if needed. Plenty of folks are running 35's on stock rims, might need a slight tweak but it's not like your truck will become undrivable.

Check the specs from their website and calculate the size based your rim width (it should be listed). Most tire manufactures will state for every .5" change in rim width = a .2" change in tire width when mounted.

If you end up going with 1/4" spacers, I would strongly advise against the cheap parts store ones (see pic below).
Previous owner had installed a set of those, and they did not allow the wheel to properly center on the hub, which caused a wobble/vibration at highway speeds.

Spacers to avoid.
