Toyota 4Runner factory tire sizes run from 245/70R17 and 265/70R17 to 265/70R18, 265/55R20, and factory 33-inch tires.
This 4Runner Tire Size Chart is built for one job: helping you match your year and trim to the factory tire size without bouncing between forum posts, dealer listings, and random fitment tools. If you’re buying replacement tires, wheels, or a full-size spare, starting with the stock size keeps the whole job cleaner.
The 4Runner stayed pretty steady for years, then Toyota shuffled the deck with the new generation. Older trucks usually sit on 17-inch or 20-inch setups. Newer trucks add 18-inch packages and factory 33s on the top trail trims. That split is where most wrong orders happen.
How To Read A 4Runner Tire Size
What The Numbers Mean
A size like 265/70R17 tells you three things. The first number is tire width in millimeters. The second is sidewall height as a share of the width. The last number is the wheel diameter in inches.
So a 265/70R17 is wider and taller than a 245/60R20, even though the second tire fits a bigger wheel. That catches a lot of owners off guard. A bigger wheel does not always mean a taller tire. On many 4Runners, it means a shorter sidewall and a more street-biased setup.
- 245/70R17 = narrower tire, taller sidewall, 17-inch wheel
- 265/70R17 = wider tire, tall sidewall, classic fifth-gen stock size
- 265/70R18 = wider tire, taller overall stance, 18-inch wheel
- 265/55R20 = wide tire, shorter sidewall, 20-inch wheel
Why Year Matters So Much
Two 4Runners can wear the same trim badge and still use different tires if they come from different generations. Limited models are the cleanest proof. Fifth-gen Limited trucks used 245/60R20. The newer Limited moved to 265/55R20.
TRD Sport can trip people up too. Late fifth-gen trucks used a 20-inch setup with P245/60R20 tires. The current-generation TRD Sport also rides on 20s, though the tire itself changed to 265/55R20. Same wheel diameter, different rubber.

This chart is built around stock factory sizing, not lifted-truck wish lists. If your 4Runner came from a dealer with add-ons, or a past owner liked to tinker, check the driver-door placard before you order anything. Badges help, but the sticker tells the truth.
If you want to verify a late fifth-gen or sixth-gen truck against Toyota’s own material, the 2017 4Runner press release shows the fifth-gen 17-inch and 20-inch split, and the 2025 4Runner launch release shows the new 18-inch packages and factory 33s.
Toyota 4Runner Tire Sizes By Wheel Diameter
17-Inch Setups
The 17-inch sizes are the stock sweet spot for a lot of 4Runner owners. On the fifth generation, 265/70R17 became the familiar do-it-all size. It gives you a tall sidewall, a planted look, and enough cushion for rough pavement, washboard roads, and mild trail work.
The new SR5 moved to 245/70R17, which trims width and overall height a bit. That makes sense for a base trim that leans harder toward daily driving. It still keeps the smaller wheel and taller sidewall formula that suits the 4Runner well.
18-Inch And 20-Inch Setups
On the sixth generation, Toyota added a stronger middle ground with 265/70R18 on TRD Off-Road models. That size is taller than the old 265/70R17 and brings a beefier factory stance without jumping all the way to 33s. If you want a stock-size replacement that keeps the new truck’s off-road flavor, this is the one.
The 20-inch sizes tell a different story. Fifth-gen Limited and late fifth-gen TRD Sport trucks used 245/60R20. The new TRD Sport, Limited, and Platinum use 265/55R20. Both setups lean more toward on-road response and a dressed-up look than the classic 17-inch stock package.
Stock Sizes Compared Side By Side
| Stock Tire Size | Approx. Overall Diameter | What That Feels Like |
|---|---|---|
| 245/70R17 | ~30.5 in. | Smaller current-gen stock size with a lighter daily-driver feel |
| 265/70R17 | ~31.6 in. | The classic fifth-gen all-rounder |
| 245/60R20 | ~31.6 in. | Nearly the same height as 265/70R17, though with less sidewall |
| 265/55R20 | ~31.5 in. | Current-gen sport and luxury stock size |
| 265/70R18 | ~32.6 in. | Taller stock off-road setup on the new truck |
| 33-inch on 18 | ~33.0 in. | Factory max on TRD Pro and Trailhunter |
That size table clears up one common mix-up: a 20-inch wheel package is not always taller than a 17-inch package. Fifth-gen 245/60R20 and 265/70R17 setups sit close in overall height. The real change is sidewall depth, ride feel, and wheel look.
The new 265/70R18 and factory 33-inch setups do bring more height to the party. That means a chunkier stance, more sidewall than the 20-inch packages, and a stock setup that already looks close to what many owners used to chase with aftermarket tires.
Before You Order Tires Or Wheels
Check The Sticker, Not Just The Trim Badge
Use the chart to narrow the answer fast, then confirm three things on your truck before you buy:
- Model year
- Trim
- Door-jamb tire placard
- Wheel diameter already on the truck
- Load rating on the replacement tire
That last point matters more than people think. Even when two sizes look close, load rating and construction can change how the truck rides, brakes, and carries gear. A 4Runner is not a featherweight crossover. It likes tires built for the job.
Don’t Forget The Spare
The spare can save you from a bad tire order. If your truck still has its original full-size spare, crawl under the rear and read the sidewall. That gives you one more stock-size check before money leaves your wallet. It also tells you whether a past owner changed only the four road tires and left the spare behind.
If you want the short version after all of this, here it is: most fifth-gen non-Limited 4Runners use 265/70R17, fifth-gen Limited and late TRD Sport trucks use 245/60R20, the 2025-2026 SR5 uses 245/70R17, new TRD Off-Road trims use 265/70R18, and TRD Pro or Trailhunter models ride on factory 33s. Match the year first, then the trim, and the rest falls into place.
