The Land Cruiser 79 Series Single Cab runs a stock tyre size of 265/70R16, and the Double Cab runs 265/65R17. The most common upgrade for both is 285/70R17 — roughly a 32-inch tyre — which fits a standard vehicle without modifications.
Stock and Upgrade Sizes
| 79 Series | Stock Size | Common Upgrade |
|---|---|---|
| Single Cab | 265/70R16 | 285/70R17 |
| Double Cab | 265/65R17 | 285/70R17 |
The split catches a lot of owners out: the Single Cab leaves the factory on 16-inch rims, the Double Cab on 17-inch. If you’re moving both onto a matched set — common when running a spare across two vehicles or building a fleet — 285/70R17 is the size that unifies them.
How Far You Can Go
The 79 is leaf-sprung at the rear and built to carry, which makes it forgiving with tyres — but the limit on a stock vehicle is still around that 285/70R17 (32-inch) mark. Step up to a true 33-inch tyre or bigger and you’re into suspension-lift territory, with possible bump-stop, wheel-arch or even minor body-mount tweaks to stop the tyre rubbing on full lock and under load. The closer you keep it to stock, the better it drives loaded and the less you stress the drivetrain.
For overland use most 79 owners land on a 285/70R17 all-terrain and leave it there — it clears, it carries, and it doesn’t wreck the fuel figure.
