Installed: 37s with NO LIFT on JLUR

[OnlyOne]

bfg 37s are also not 37s

That’s like saying a 2 or 4 door isn’t a real Jeep. I cant tell you how many times people post this horseshit. There may be one tire that gets anywhere close to a measured loaded height. That’s not even how manufacturers spec them. If it says 37 on the sidewall, that’s how they are measured. Everything on these Jeeps have a range. When lift manufacturers spec out what recommended tires to use, they use what’s on marked on the sidewall. A 37 is a 37. Even if it’s not one you recommend or have chosen.

Most are not perfect true to size, but you can roll a bfg k02 next to a cooper, nitto or mile star and they look like a size smaller. See post 83 from OP. hardly horseshit.

I must admit my next maybe a bfg km3 39”. They seem to be closer to size and 38.5” sounds damn near perfect.

37/13.5r17 Toyo MT, 37/12.5 BFG AT KO2, 315/70r17 Nokian Hakkapeliita

Unloaded heights:
37", 36", 34.5"

So yeah, this particular tire and size is not a 37" tire.

Off topic. What trail is that in your avatar? Hells Gate?

My point wasn’t that the are all the exact size. They’re not. It was that, a 37 is a 37. There are larger and smaller but we could go all day talking about lifts, tires etc......many different ranges of specs in the Jeep world. I’m not a BFG lover by any means, although I run them as an all terrain and they are terrific for all around driving like I need up here. People just need a standard to go by and manufacturers try and get there.

Yes. It is a 37. That’s what the sidewall says. That’s what the manufacturer builds and what recommendations are based off of. That’s the point.

Any idea if these are mounted & inflated? That looks like a lot more than 1/2"

A 37x12.5 K02 is supposed to be 36.5" tall: https://tiresize.com/tires/BFGoodrich/All-Terrain-TA-KO2.htm
While the 37x13.5 Toyo claims 37": https://tiresize.com/tires/Toyo/Open-Country-MT.htm

Also, this is the same problem as lumber sizes.

No the point is they've got it labeled fucked up. It isn't even close to a 37" tire. They could easily use metric tire sizes and come up with something that makes sense and is a real representation of the tires size.

Not a perfect analogy here, but I'll go ahead anyway:
9mm Luger is not equivalent to a .357 sig, nor 38 special, 357 magnum, or 38 super
Similar sure, but not the same.

When a tire manufacturer advertises a certain size tire, it should certainly be very close to what they claim. Why are you upset that people like to spread the word and give true presentations of what a product actually is?

I think they are all on the preferred/recommended wheel sizes.
The toyo is on a 10" wide wheel. Bfg is on an 8.5". And the 315 is on a 9".

yes 2019 EJS nearly over. Got the stop sign from spotter as rear started to slide.

Honestly I wasn’t trying to be a douche, but from personal experience a real or close to 37” tire rubs with no lift on the rear, where a k02 may work. If you set your 37 k02 to 37” with your tazee your giving yourself some extra miles on it. Check it with a GPS if you don’t believe us.

I replied to the wrong post, and also I thought the looked smaller than 36. One of the guys at EJS had them and it looked like a 35 compared to the other rigs on SST pros. And yea maybe it was wheels size, or tread pattern. It certainly wasn’t pressure.

Just like TVs, a TV that measures 31.7” is a 32” “class” TV.

Most 37s do not actually measure 37" in height from the ground when mounted on the Jeep. Most all fall in the 35.5" - 36.25" range. Measuring them when not mounted on the Jeep is not an accurate representation. There are also variables such as tire pressure, tread life, the Jeeps weight, and rim width (a narrower rim will make the tire stand more proud and have a slightly larger diameter).

These K02s measure 35.5" mounted. Like I said, on the small end of the spectrum but yes, technically, still 37s!
