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.

I went with Blizzacks in the 265 size on my 1958. Between that and a roof box mileage declined about 1Litre per 100km. They don't roll as well as the geolander but are still light and get great traction on snow and ice. I have noticed no difference in suspension or speedometer. I used the factory wheels (swapped the tire onto the original rims) since getting the right offset seems difficult. Will likely get a wheel and tire set when the geolanders wear out or I may just buy a set of stock rims if they become available.

I put 265/70r18 Cooper Discover Road+Trail AT on the OEM 1958 wheels. Awesome tire, about 7,000 miles on them. Improved the ride and great on dry, wet, and snow. Saw minimal to no MPG impact after about 500 miles breaking the tire in (although the LC was breaking in at the same time). There is no mechanical difference between the 1958 and higher trims as far as the suspension and dynamics go. The wheel width on the 1958 is fine for 265/70 and perhaps larger depending on the tire.
