Long post ahead!!!! We gathered some tire and wheel data yesterday while helping change out some tires on wheels on the Ultra4 Comanche.

A lot of info below, and keep a look out for us on the trails as we do some direct comparisons between tires on our rigs this year.

​40” Toyo MT
40” Nitto Kspec
39” Red
40” SX2 sticky.

The red label and the nitto are practically identical in height while the toyo and the sx2 are marginally shorter.

All 4 are between 13.25” and 13.75” wide at widest part of sidewall.

In comparison to the 43” SX sticky @ 15” wide. Apples to oranges.

The vision manx aluminum weigh right @ 36 lbs.

My allied steel bead locks weight 43 lbs.

40” toyo MT weighs 94 lbs
40” nitto k weighs 114 lbs
39” BFG red weighs 93 lbs
40” sx2. Weighs 94 lbs.

The durometer readings I’m going off memory and Ken can correct me if I don’t recall correctly.

Insert Barry bonds size asterisk*. We did not accurately normalize all 5 tires tested (43” included) to all the same temperatures. The red labels are in 78° a/c shop, everything else was in 86° shop. Red labels read hard on the durometer, and I’ve seen 20 point drops in hardness just getting them out in the sun on the trail. Reds are different compound entirely and the softness of the rubber doesn’t equal stickiness, and the Toyo are dot compound. All tires ages vary widely. All are taken shore A scale.

Toyo. 77-78.
Nitro 55-58.
Red. 76-77
Sx2 47-48
43” SX. 58.

There is a far greater difference in tire weights compared to steel vs aluminum wheel weights, despite everyone on the internet screaming about aluminum wheel weight savings.

My 42” SX2s on h1 wheels with rock rings and run flats were 230 lbs each.

My red labels on allied steel bead locks are 136 lbs each.
