Toyota 4Runner is an SUV that is good for offroading while passing through rough terrain and for comfortable daily cruising on even pavement. 4Runner drivers value their vehicles for a reliable powertrain, a decent ground clearance, and various trims.
Usually, many 4Runner owners desire to improve their vehicle’s outlook by mounting bigger tires on them. With so many different tire options, you may be wondering.
What are the biggest tires that can fit a stock 4Runner?
According to the manufacturer, a 31-inch tire is the biggest size for a stock Toyota 4Runner.
The largest tire size that can be installed on a Toyota 4Runner with stock suspension without any side or additional mods is a 32-inch tire. It fits wheel wells without issues and provides no rubbing or scrubbing of fenders or suspension components.
We’ve spotted that one tenacious owner of a custom-built 4Runner even succeeded in mounting 33-inch tires on his stock vehicle. However, with no issues, a 33-inch tire only fits a stock 1987 Toyota 4Runner SUV.
Stock Toyotas produced from 2015 to 2021 can also fit 33-inch tires. While installing 33-inch tires does not involve trim work, tires may slightly rub at full turn.

We only provide tire sizes that do not result in any rubbing and require no fender trimming or changes to the factory suspension.
What size tire can I fit on a stock 4Runner?
Available tire size fitment for a stock 4Runner may differ and depend on the rim size, year of SUV production, and your preferences. Usually, tire sizes for Toyota 4Runner vary from 29 to 32 inches. The largest tire size that can be mounted on most stock 4Runners is a 32-inch tire. Regarding 32-inch tire parameters, they have two options: 265/75R16 or 265/70R17.

The mentioned further tire sizes fit 4Runner’s of a particular year of production. People claim they fit SUVs’ stock suspension and don’t require any leveling, lift kits, or body cuts for tire accommodation.
