Anyone Running 325/60r20’s (35.5x13)?

[Utemachine]

They are slightly larger than a 35’s without taking the leap up to 37’s. I haven’t seen anyone running this size. Anyone with pics they could share?

Interested in seeing this size as well. A lot of the tires listed this size are light than the 35x12.5 version

I’m pretty certain I’m going this direction with Ridge Grapplers and 20x10 wheels. This size is only available in a load “e” and run about 8lbs heavier per tire than the 35x12.50.
I’m going to put the RC 5” on as I have air ride. Any advice on the offset I should run?

Where do you see that? I’m seeing that the 325/60 is lighter on nittos website

Good catch! I’m not sure where I saw that. I also didn’t realize the 35’s were load F.

I was just making sure I wasn’t reading wrong! Haha. Yea I was dead set on get the 35x12.5 ridge graps next go around (I currently have the 35x11.5) until I found out they were only available in load F

Which offset did you end up using? any rubbing issues or trimming required with the 325’s?

I am so keen to follow your lead on this setup, so many conflicting fitment stories on here though!

I’m very interested to see what the “true size” of the tire is because I’ve considered it too! I know of a guy who put 325/60r20 TRAILgrapplers on his 5th gen ram & they look huge. I asked him for the true size and he sent me a video measuring where it sure looked like they were 36” tall and he said he thought it was about 36. If that’s true, that’s bigger than most 37s which is weird! I can’t imagine that being true. If you actually take the revolutions per mile of any tire it’ll usually tell you close to the true diameter of it mounted. Using math, it would say that 35x12.50r20 ridgegraps are 33.73” tall, along with 12.5” wide, load rating of 3640, weigh 73.5lbs, & tread depth 18.3/32. The 325/60r20 ridgegraps would be 34.3” tall, 13” wide, load rating 3750, weigh 69.8, & tread depth 16.4/32.
So basically 325s are .60” taller, .50” wider, 3.7lbs lighter, have a higher load rating, and have less tread depth. I’d assume with the higher load rating that the tire would be stiffer, especially considering it only takes 65psi to reach max load cap, whereas the F load 35s take 80psi to reach a lower max cap. Hopefully this info helps you decide what’s best for you!

I believe the 325’s are 35.4x12.8”

I believe the 325’s are 35.4x12.8”

That’s what they list them at, but that’s not the true diameter once they’re mounted. Just like how most 35s actually measure around 33 7/8 and most 37s are around 35 3/4

Also keen to see some more pics/info re 325’s from OP if possible??

I know this is an older post but pulled the trigger on some Nitto Recon Grapplers in 325/60r20. Switched from 35x12.50r20 Ridge Grapplers. Slight rub by the pinch weld and on the liner but nothing a little heat gun and trim won’t fix.

Looks great! That's my next tire size for sure. Don't want to go with 37's but I want bigger than 35's. That and the Yokohama's in the 315/60's are the sizes I'd consider. Thanks for the pics, it's hard to find a 5th gen on 325/60s.

Also I agree with 5thgen.ram above, I always look at the revs per mile. It's really the truest way to tell. Or if I stay with a 35 I'll go to a taller 35 like a Trail Grappler or Yokohama MT, or Toyo MT.
