Wanting some real 33 inch tires

[Jeff Allan]

Thanks to this awesome forum, I snagged a nice '04 Rubi back in winter. It has Falken 285's, which are often called 33"s, but listed actual size is less. The real size under the Jeep's load is 31.5" or so... with 37 psi.

Also have a JK with KO2s in same size, and it's the same thing, quite smaller than advertised, like 1.5" less.

I'm getting ready to get a lift and with the 4.10 gears, and five speed, I'd like to get a tire that actually is close or over 33". The Jeep now has plenty of power, I can pass/accelerate in fifth gear and take off from a dead stop in 2nd gear. Has original moabs which are 16". So do I look for something like a 315/75/16 so the supposed 35" will be close to 33"? Does that even make sense!?

Looking for suggestions on what's biggest size that won't make it feel underpowered or then have to start changing a lot of other components. Tires I like are KO2s, Wildpeaks, Dick Cepek FC II, and Mastercrafts. I like they hybrid AT/MT type. Gotta be good in snowy weather.

KO2s always run smaller than their advertised tire size. i had 37 inch KO2s on my old jk and they were 35.5 mounted and on the ground.

Most tires are smaller than their advertised size due to the fact that the manufacturer measures them unmounted and aired up to the max. Toyos probably run closest though..

That's a pretty good trick. Got any pics of that in action?

haha if i did i'd be a tire guru! I just know they don't measure their tires mounted and at 28 psi.

I am running Toyo A/T 3’s-295/75-16 and according to Toyo they are 33.4”

That's a really nice looking tire too. Looks like it'd be good in snowy/wet stuff, with all the siping. But kinda aggressive look. Good size if they are close to that. Do you have a pic? Did you ever see how close to specs they are?

This would all be so much more fun if folks would measure their tires horizontally.

I think you are wanting a 33” tire mounted on your Jeep and under a normal load to still measure 33”. If that’s correct then a 315 ko2 will measure a hair over 33”.

You can’t measure the height of something horizontally.

Don't be a moron. You can't measure the height of a loaded tire and expect the result to be accurate. What if one idiot puts the tire on the rear of a lightly loaded TJ SE and the next idiot puts it on the rear of an overloaded TJ Unlimited that weighs 5500 lbs?

That and you clearly overlooked the obvious, tires are not measured by height, they are fucking measured by diameter.

Calm down, it was a joke. Sheesh.

I think the majority of people just want to know what the size is on a normal Jeep without a bunch of gear in it. A stock Jeep without a bunch of stuff a 315 is going to be a hair over 33”

Just to be clear, you’re agreeing with the obvious notion that people want to measure the height of the mounted tire, not the diameter...correct? I’m not sure why Blaine struggles so much to grasp that threads like this are blatantly referring to height.

Yes lol

You have tire idiots?

A lesser known but becoming more common side effect of the virus bullshit is the diminished capacity syndrome. The longer it goes on, the dumber previously smart folk get. As such, I seem to have been able to encounter a plethora of idiots on just about every subject possible lately and I just ain't that smart.

No one cares what it measures horizontally, because clearance of the axle doesn't happen horizontally, it happened from where the tire compresses under the weight of the Jeep. My 33 inch KO2's measure about 31.5 inches. If what SCiotola said is true, than I would buy KO2's labeled as 37's and treat them as 35's if I wanted 35 inch tires. Also, if you go onto GrimmJeeper and punch in 35 inch tires, its not going to account for the fact that your tire may run small or that it gets compressed by the vehicle. So if you want dead on accurate results for choosing your gearing, go off the exact vertical measurement of the tires at whatever PSI you run them on the road.

I'm sorry to hear about this diminished capacity syndrome. I hope you get better soon

I had the Toyo A/T 2’s on a Land Rover and they were great in the snow
