What size tire are you really running?

[AaronPaige]

So late winter I bought 37s for my tj and haven’t had it out much last night I ran a trail and my new 37s are smaller than the 35 I took off and gave to a friend (well used), is interco the only ones selling small sizes?

I’m thinking about replacing them with Maxxis treps if you have them did they balance well and are they true to size?

I bought a set of 33 falken at3w's and they measured out at 32 inches at 30psi....

My 44 inch TSLs measure right at 41 inches at 10 psi

My 43" SXs sit at 41" at 6psi, at 20psi they are just shy of 43"

Back when I was building my YJ and I bought 4 brand new pitbull rocker 42's... 2 measured at almost 43", and 2 measured at 40"; (10 psi, no weight load). I was flabbergasted at the visible size difference to the naked eye.

43" SX: 39.25" @ ~5psi
I'd guess they have close to 1/4" of tread wore down. Had them since 2012.

Well now I know what to use when I step up to a true 40

I'd like to see more posted in here. Would be intersting to compare over time.

Brand new 315 75R 16 BFG KO2's measure 33.5" @40 PSI

edit:
for sheetz and giggles I measured the 1/2 tread KO's I have as spares and trailer tires, 34" @40 PSI

New 265/70/17 - Pathfinder all-terrain (Hankook Dynapro ATM clone) 30"
Old 265/75/16 - BF Goodrich rugged terrain A/T 30.5"

I thought 265 tires were supposed to be closer to 32"

 

[WILDHAIR225]

BFG KM2 37/12.50/17 about 1/2 tread and trail pressure of 18 psi they measure 34.5

It would be nice if tire manufacturers were held to a standard. I feel like this is kind of a "bait and switch" game.

One of the reasons I did choose my 43" SX was because a few people on Pirate reported that they came closer to a true 40" and that was the size I was aiming for. That and I love old school swampers.

Now that I'm looking for tires for a taco build, I ultimately want to end up with a true 35", which is looking like I might just go with a 37... But I may stick with a 35 anyways. Still undecided, and it doesn't help that I'm not sure which brand to go with yet either, especially since they seem to vary in sizes brand to brand.

I'm liking those KM3's for my next tire, which will be a 37.

I think I'm leaning toward that tire too

I heard from someone (can't remember who now) that a 37" tire will be 37" tall at 65 mph. It's not a static measurement, but a dynamic one? Made sense to me. I have a set of 40" Maxxis Creepy Crawlers and Razr MTs. I should measure them and post up....

my 44" TSL's with about 6 psi in them measure out at 40" tall
