37’s which one???

I’m going to get 37’s on the stock 20 inch wheels. Question is which tire to go with. It’s not just a brand question either. I’ve narrowed it down to the Toyo open country MT’s, Cooper’s SST Pro’s, and Nitto trail grappler MT’s. The Coopers are the cheapest by about $300. The Nitto’s have the option to go 37x11.5 which I believe would negate the rubbing issue. The Toyo’s are the most expensive but still very cool looking and seem to be very popular on the forum. I wish I could test out a 37x12.5 just to see how much the rubbing effects daily driving.

I don’t think Cooper make the S/T Maxx in 37x12.5 r20. So the STT Pro is the model I’m looking at. $311 each.

Living vicariously through my son's truck, or something like that. He got Toyo 37 x 12.50 x 20 RT's w/ 4" BDS lift. He rubs a little at full lock on the arms w/ the factory 20's.

I love the aggressive look of the MT's, I've had two sets so far and have had no issues with them at all.

How have these STT's worn so far? How many miles do you have on them? Thinking these will be my next set and curious about wear on a heavy pickup.

I’d like to do a 37x12.5 but I don’t want to deal with rubbing issues. Is there a radius arm out there that provides the necessary clearance?

alternatively ..... I do the 37x11.5

does anyone run a 35x13.5? Do they rub? Thx

Pretty much all of the Radius Arms out there allow for wider tires. I'm not sure if a 13.5 wide tire would rub, I think its the length of the 37 from the hub that makes it rub, not the width.

i haven’t noticed any uneven wearing with about 7k miles. I have rotated them but haven’t towed yet though. They are noisy, but not obnoxious.

Thanks for the update on them! Looking forward to hearing how much life you actually get out of them.

You keeping the stock wheels? A 13.5 tire on an 8inch rim is really pushing it.

I've ran both the Toyo MT's and the Nitto Trail's on half ton and 3/4 ton trucks. They are a very close 1st and 2nd choice for me every time. I give the slight edge to the Nitto's for longevity and wear on the heavy trucks and the weight ratings are usually higher.

Oh and I'm also a fan of the tall and narrow look (to a point) lol. These new trucks look awesome with a level kit and 37's im struggling with tire size myself between 35 and 37.
