New skinny 33" tire sizes for 18" wheels? (2 Viewers)

[FairZ33]

I was messing around on tiresize.com and noticed there are some new (at least I think they're new) tire sizes that are basically 33" without being almost 11” wide.

245/75R18
The X-AT in SL load from Yokohama comes out to a 32.5" tire at only 9.7" wide.
The A/T4 in E load also from Yokohama, 32.7" tire at 9.9" wide.

235/80R18
The KO3 still in E load, 32.8" no width listed, but can't imagine it's wider than 10"

Has anyone any had any of these installed on the stock 18" wheels? Probably not big enough to cause any rubbing, but maybe this is a sign that tire manufacturers will start offering skinny 34 or 35s for 18" wheels in the future. Maybe I don't need those expensive rock warriors after all.

Interesting sizes but a 235 or 245 on the stock 8” wide wheel sounds like a bad idea to me.

235mm/25.4=9.25"

Curious to hear your reasoning on that. I’m not super well versed in all of this. Still learning.

Wider tires protect the rim from rash. 235's will fit perfectly flush on an 8" rim, zero bulge. I guess if it's a pavement pounder and you're searching for top MPG it would work.

Why do you say this?

Because it’s true?

100’s in the Middle East were offered with 225/95/16’s but they came wrapped around a narrow 6” wide wheel.

It's not. The tire is 9 1/4" wide. An 8" rim is dead smack in the middle of the ideal rim width for a 235 tire. There are numerous reasons to run a different combo, but there's nothing wrong with a 235 on an 8" rim. My Camry wears 235 tires on 17x8 rims. The tires are not flush with the rim.

I am the same market - looking for a good pizza cutter tire for a factory 16” wheel.

A Land Cruiser is not a Camry. Tell us all about the off roading you do in your Camry.

It is true. A wheel's width is measured on the inside, between the beads. The overall width of the rim is about 1" wider than the "official" width. An 8" rim measures about 9" on the outside, 9 x 25.4 = 228.6mm. 235 - 228.6 = 6.4mm, divided by 2 will give 3.2mm of bulge, or about 1/8" of an inch. will it fit? Of course it will. Will you shred your rims if you go off road? Of course you will.

If this is a concern for the OP, I missed it.

All of the tires linked are all terrains. One would assume they would be used in that manner.

Skinny tires work well offroad and they help with mpg, but make the truck look like it skipped leg days. I’d be more worried about on road handling as well since there’s less contact on the road, unless you widen your stance a bit to offset the skinnies

The 235-245 width tire will work, just less than ideal. 6-6.5” would be best. Would be tough to find an 18x6 wheel but an 18x8 steel wheel could probably be narrowed to 6”.

Maybe I’ll pick up a set of Tundra steelies and then I won’t have to care about scratching the wheels? Why doesn’t anyone make a 255/80r18 tire? Ugh… or a 5x150 17x8” wheel with factory (or near) offset? I want pizza cutters without having to drop too much money on rock warriors that still need to be refinished.

Having a narrow tire on a wide wheel also increases the possibility of losing a bead.
Rock Warriors are 8” wide as well.
There’s good reasons why most here with 18’s choose 275/70’s.

No sign of things to come.... The 245/75R18 is stock size for 2022+ Tundra. The 235/80R18 is stock for 2024+ GMC/Chevy 3500's. They are also used in the Dual Rear Wheel configuration.
