Tall 245 tire options for LC 250 1958? (4 Viewers)

While I will be surprised if it does not receive the 9.5 diff for reasons stated above, that's not a litmus test, just as solid front axle is not a litmus test. I would prefer both, but more so I trust Toyota engineers (which I know many on this forum clearly don't) to match component parts to capabilities in a way that is sufficiently robust.

If you're including me in the crowd that doesn't trust Toyota engineers, leave me out. I trust them. It's those that take the engineer's recommendations, gut them, and then spin them for company (excess) profit that I don't trust. Could they make a much better LC250/GX550, etc. and perhaps make a little less than $61.699B (+33% YOY) in a year, maybe... I don't trust the marketers, economists, executives, and lawyers - and some of what they do for the shareholders.

The engineer's don't operate in a vacuum, and for that reason, we have Land Cruisers almost 75 years later.

I'm not aware of Toyota gutting engineer recommendations with Land Cruiser. Toyota engineers work within various design constraints to render Land Cruisers that have always been sufficiently robust for their capacities and capabilities. There's no evidence of that changing now.

This is not to say that Toyota is not guilty of nefarious corporate sh*tbirding. Toyota has for decades force fed the U.S. market needless luxury bloat on Land Cruiser platforms that it sold for large fractions less in base spec globally.

Dont worry about stock width tires. Replace the wheels and tires and get a setup that properly fits this thing. 33"tires should fit fine and some beefy 18 wheels with decent offset will really transform the look of these.

Yeah, just a little more height will do it for me. I prefer keep stock wheel and track width if compatible with a taller skinny tire.

Agreed with a comment on this point..

They wouldn't exactly publicize that, now would they? Companies gutting subject matter expert recommendations is a hallmark of capitalism.

The engineers know their constraints and design goals and they do their best to stay within the lines provided them. But the sky is also blue.

So, we need a Land Cruiser engineer whistleblower hotline?

Just kidding.

As a consumer, I'm fine with whatever internal wrangling has transpired so long as Land Cruisers are sufficiently robust for their capacities and capabilities. I expect there's more debate about design objectives and constraints than the engineering within those. It'd be very interesting to learn more about that process.

One thing that has blown me away lately in some recent digging is the depth of the regulations for environmental and safety aspects of car production. It's crazy.

For instance (as I understand it), for them to offer these ARB bumpers on the Tacoma Trailhunter would have required them to perhaps modify designs and perform separate crash testing to certify both designs in different crashes. Does the ARB bumper do the right thing when hitting another vehicle? Does it do the right thing when hitting a pedestrian? Does it offer the correct energy dissipation and failure characteristics where it interacts with the rest of the body and chassis. Those weight changes due to the modified bumper affect fuel economy and the environmental regs. It's amazingly deep and complex.

And without really understanding those regs, it might not make sense why Toyota puts a 245 tire on the Land Cruiser..but if you knew what 27 MPG would do for their fleet CARB average or whatever, it might make sense.

The LC70 comes in many markets with 215 wide tires in some markets I think. Or at least it used to. It probably depends a lot on what you want to do with it. If I wasn't planning on going into deep snow, mud, or soft sand, the extra mpgs from the 245s might be nice. I one had a set of 235/80/16s on a truck. They were fine for what I was using it for. Low rolling resistance, easy on the steering, and fine highway tracking. They were perfectly fine on ranch roads too.

Not what I'd want for harder off-road use. But - none of the OEM tires are what I'd choose. I'd prefer Toyota put something like the Bronco tires on. But if Toyota's gonna toss some rollers on, the cheapest ones they can in a size that maximizes EPA ratings makes sense to me.

Rock a true skinny 235

Yes, global market 76, 78 and 79s see 225/95r16. I’ve liked 235s and 255s and would happily to try a tall 245r18 if one existed. The 245s on the 250 are undoubtedly targeting mpg with an assumption that most buyers will immediately replace them.

Do we know if the 1958 version with 245/70 tires has the same differential gear ratio as the models that come with 265/70 tires? Or does it have higher gearing?

 

[Hiluxforever]

Won't know until we see axle codes, I presume it's a slightly different ratio. I think LT275/70R18s are the ideal size for these as there is a ton of options in that size

Based from this all 8 speed 4 cylinder got 3.538 gear.

How did you go with this?
Noticed there’s another size available now for skinny 33s being 235/80R18.

Thread 'New skinny 33" tire sizes for 18" wheels?'

Mar 15, 2025

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...
