Yes, theyre technically taller, I have personally seen a set side by side and theyre about the same, i would maybe say the 36's are taller, but mroe balloony, if you want a more square, radial looking carcass go with the 37's.
I have 36" bias and my friend has 37" bias, both on 15" wheels. My wheels are beadlocked 15x8 so they are technically a 15x9 and his wheels are 15x8. The 37's are bigger but not by a lot.
Previous posts compared bias vs radial, the two will always measure differently because of the carcass construction.
My 36's gain probably 2-4" of height when i air them up. I normally run 1-5psi on trail, aired up is 15-25 (for storage).
The size is not enough to warrent more $$$ when buying. My friend bought the 37's because they were like $10 per tire cheaper.
you seen em under rigs, or dismounted?
i wonder if you put them at wheeling psi, under a 4,000lb rig, if the "squarish" 37s would be sittin taller..
Hey, wait a minute here! Yours were basically new! :haha:both sets were under rigs, side by side, comparable setups mine a 5000lb s-10 and his 4000lb or lighter a toyota, I think we were at the same psi, i might have been lower, and we were about even... at that point youre splitting hairs and i felt the 36's performed better... personal opinion though!
I think there is more of an open tread pattern on the 36s even compared against the 37s....
Hey, wait a minute here! Yours were basically new! :haha:
I think theyre about the same size too. If there was any major height difference it was due to the fact yours had more tread than mine, and you're right, its splitting hairs. If you are looking at something for a setup where that small of a difference makes or breaks it, I would look at something else to fix the problem (different offset wheels perhaps).
Id buy whichever is cheaper. I wanted 36s, ended up 37s used with 80% tread or so for less than 36s new obviously. I remember the tread being the same, but I could be wrong. I know mine are cut every other lug too, so that makes them look a little different.
