Question on Upgrading Wheels & Tires LC 1958 (245/70R18) to (265/70R18)

[lightspire]

Considering upgrading from 1958 OEM ( 245/70R18 ) Wheels/Tires to OEM ( 265/60R20 ) or OEM ( 265/70R18 )

Tire Calculator indicates the larger OEM sizes causes the "diameter differs by more than 3%. Is it dangerous"

1. What are the “dangers" on upgrading from 1958 OEM to Premium or First Edition OEM Tires/Wheels?

2. Are there structural or suspension differences between Toyota Land Cruiser Models for larger OEM Tire/Wheels?

3. Is there a warranty issue with going to a larger OEM Toyota Land Cruiser Tire/Wheel?

4. Suggestions on Winter Wheels & Tires for a LC 1958?

In this case, none, no, and no.

US Land Cruiser Tire (265/70R18 & 18x7½J) differs from Japan Land Cruiser VX Tire (265/65R18＆18×7½J)

Both US 1958 & Japan GX are the same (245/70R18 ＆ 18×7J) and match the diameter of the upper level Japan Land Cruiser VX Tire (265/65R18＆18×7½J)

Why would Toyota North America and Toyota Japan use slightly different tire specifications for the upper level models but keep the base models tires the same?

My initial reply was a bit short . . . end of a long work day.

I have a sheet on wheels on the spreadsheet below (second tab). The only difference I know of between the 1958 and other trims (in the US) is a slightly different fender trim but I don't think it makes much difference. I don't know if there's a different speedometer calibration for the 1958 trim? I'd be a little surprised if there is. But folks have been putting up to 275/70R18 (and even 285/70R18) tires on them without much trouble as long as they use a wheel with an offset in the 40-50 range. The 1958 factor wheel has 70 offset and is 7" wide but 265/70R18 tires should still work fine on it. The spreadsheet has a few options if you want to go with different wheels, I got the Tacoma 18" x 8" wheels with 45 offset, there's a pretty popular option. I can't imagine there being a warranty issue, especially if you stick with Toyota wheels.

It was hard to get a Land Cruiser trim w/o 20" wheels so I'm using my 20" wheels for winter tires with Michelin X-Ice Snow tires in 275/60R20. The 20" wheels are heavy, but a lot of people got them and don't want them so you might be able to get some for not very much? I think you've got a few more winter tire options in Canada than we do here.

I went from the 245/70-18's to 265/70-18's just yesterday.

I upsized to 265/70-18 Goodyear Duratrac RT tires on my 1958 rims. Mileage went down a bit but traction on snow here in the Cascades has been wonderful.

I went to 285 70 18 Breaking the rules... but I put 2024 Taco wheels on with 45mm offset and no rubbing but better clearance for offroading. MPG is the only thing that suffers

Thank you I can only seem to find the OEM replacement YOKOHAMA GEOLANDAR X-CV ALL-SEASON Tire and nothing for a winter tire in 245/70R18.

if you go up to a 255/70/18 they have a much better selection of winter tires.
