5th Gen 4Runner Tire Size Chart | Stock Sizes By Trim

Factory rubber on the fifth-generation SUV is mainly 265/70R17, with 245/60R20 on Limited and later TRD Sport models.

The fifth-gen 4Runner ran for a long time, so tire questions pile up fast. One seller says the truck is stock. Another says it has the “normal” 4Runner size. Then you find out there were two main factory setups, not one. That’s where people lose time and buy the wrong rubber.

The good part is that Toyota kept the stock tire menu tight. Most fifth-gen trucks left the factory with either 265/70R17 or 245/60R20. Once you know which trims used each setup, the whole picture gets easier. This article lays out the stock sizes, the trim split, the years that matter, plus the mistakes buyers make.

What The Stock Fifth-Gen Setup Looks Like

From the start, Toyota split the fifth-gen 4Runner into two lanes. SR5 and the trail-focused trims rode on 17-inch wheels. Limited rode on 20-inch wheels. That pattern stayed in place through most of the 2010-2024 run, even when trim names shifted from Trail to TRD Off-Road and Toyota added new special editions.

The 17-inch trucks are the ones most owners picture. They carry more sidewall, ride better on rough pavement, and open the door to a much wider batch of all-terrain choices. The 20-inch trucks lean more toward road manners and sharper turn-in, but they give up some cushion and some off-road tire options.

That split is why “4Runner tires” is not a complete answer. A Limited owner and an SR5 owner can park side by side and still need two different sizes, two different sidewall heights, and two different replacement plans.

Why The Same SUV Shows Two Stock Sizes

Toyota did not keep tossing fresh factory sizes into the mix every few years. It kept coming back to the same pair. That makes the used market easier to read, but it also creates mix-ups. People see a TRD badge and assume every TRD trim sits on the same rubber. On the fifth-gen, that is not how it works.

TRD Off-Road and TRD Pro stayed tied to 17-inch wheels. Limited stayed tied to 20s. Then TRD Sport arrived for 2022 and joined the 20-inch side. Once you sort those branches, the size chart stops looking messy.

How To Read The Numbers On A 4Runner Tire

Take 265/70R17. The first number is width in millimeters. The second is sidewall height as a ratio. The last number is wheel diameter in inches. So a 265/70R17 tire has a taller sidewall than a 245/60R20, while both fit the same fifth-gen platform.

For most owners, the main takeaway is simple. The 17-inch setup is the friendlier place to shop if you want a stock replacement with more sidewall and more tread choices. The 20-inch setup still works well, but it leans harder toward on-road use and usually costs more once you start comparing similar tire lines.

If you want Toyota’s own trim breakdown from the end of the generation, the 2024 Toyota 4Runner press material still shows TRD Pro on 17-inch wheels while Limited keeps its 20-inch setup.

5th Gen 4Runner Tire Size Chart By Year And Trim

Years And Trim Group	Stock Tire Size	What To Know
2010-2013 SR5	265/70R17	Factory 17-inch setup and the easiest stock replacement path.
2010-2013 Trail	265/70R17	Same core size family as SR5, with more dirt-road intent.
2010-2013 Limited	245/60R20	Factory 20-inch setup with a shorter sidewall.
2014-2021 SR5 / Trail / Off-Road family	265/70R17	Mainstream fifth-gen fitment through most of the run.
2015-2024 TRD Pro	265/70R17	Factory 17-inch all-terrain-style fitment on the flagship trail trim.
2017-2021 Limited / Nightshade	245/60R20	Limited line kept the street-biased 20-inch setup.
2022-2024 TRD Sport	245/60R20	Sport trim moved to factory 20-inch wheels and 245/60/20 tires.
2023 40th Anniversary	265/70R17	Special edition kept the familiar 17-inch formula.

The chart tells the story most owners need. If your truck is not a Limited or a 2022-2024 TRD Sport, there is a good chance you are shopping for a 265/70R17. If you own a Limited, or one of the late TRD Sport models, you are usually in 245/60R20 territory.

That matters because the two factory sizes do not shop the same. The 17-inch trucks get more sidewall and a wider shelf of all-terrain choices. The 20-inch trucks still have good options, but the list gets shorter and the price per tire often climbs.

Staying Stock Vs Going Bigger

If your 4Runner still rides on factory wheels, staying with the stock size is the cleanest move. It keeps the speedometer close to stock behavior, preserves spare compatibility, and avoids surprise rubbing. That is why so many daily-driven fifth-gens feel right on stock-sized rubber.

The 17-inch setup also gives you more room to tune the truck’s feel. You can run a quiet highway tire, a mild all-terrain, or a heavier LT tire, all without changing wheel diameter. The 20-inch setup has less room for that kind of swing, so the right pick depends even more on how you use the truck.

Check The Door-Jamb Label Before You Buy

Size is only half the match. Load index, speed rating, and inflation matter too. Toyota tells owners to use the load label on the door jamb or the owner material for tire inflation specs in its 2023 4Runner Quick Reference Guide. So even if a used truck has the right size on paper, the wrong load rating can still make it a poor fit.

The spare needs a look as well. The 4Runner carries a full-size spare, but that does not mean a past owner kept it matched to the four tires on the ground. If the truck has aftermarket wheels or a mixed-size spare, catch that before you head out.

Common Shopping Mistakes On A Fifth-Gen 4Runner

Mixing Up TRD Sport And TRD Off-Road

This is the big one. TRD Sport sounds like it should share rubber with TRD Off-Road. It does not. On 2022-2024 trucks, TRD Sport uses 245/60R20. TRD Off-Road stays with 265/70R17. One trim leans street. The other leans trail.

Assuming Every Limited Has The Original Wheel Setup

A lot of used 4Runners have already been changed over. Some Limited models get swapped to 17-inch wheels for a tougher look. Others stay on 20s but wear non-stock tires. Read the tire sidewall and check the spare before you order anything.

Buying A Taller Tire Because It “Looks Close”

A tire can clear the body in a parking lot and still rub at full lock, while backing up, or when the suspension loads up off pavement. Stock-size replacements are easy. Larger tires call for more homework, more measuring, and sometimes trimming.

Common Step-Up Sizes Owners Try

Once you know the factory size, the next question is usually about a mild bump. Most owners either stay stock, step up one notch, or go far enough that trimming and wheel offset enter the chat. Here is the simple version.

Tire Size	Works Best On	Usual Trade-Off
265/70R17	Stock 17-inch trucks	No drama baseline and the easiest stock-spec replacement.
275/70R17	17-inch trucks wanting a mild bump	More height; clearance checks start to matter.
285/70R17	Off-road-focused builds	Rubbing, weight, and trimming are much more likely.
245/60R20	Limited and TRD Sport	Clean factory match for 20-inch trucks.
275/55R20	20-inch trucks wanting more width	Heavier feel and tighter clearance in some setups.

That table is a planning tool, not a blank check. Tire brand, actual tread width, wheel offset, suspension height, and mud-flap position can change the fit. Two tires with the same sidewall size can behave differently once mounted.

Pick The Right Size For How You Use The Truck

If you want the shortest path to a good result, match the truck to its factory size and buy the tire type that fits your driving.

• Daily driver with stock wheels: stay with the factory size.
• Regular dirt roads and rough pavement: the 265/70R17 setup gives you more sidewall and more tire choices.
• Limited or TRD Sport owner who likes the factory look: 245/60R20 keeps the truck close to its stock feel.
• Planning a bigger tire: check wheel offset, spare fit, and rubbing points before you buy.

For most fifth-gen owners, the answer circles back to one of the two stock sizes. That is not a boring outcome. It is the reason fifth-gen 4Runner tire shopping is easier than it first looks, once you know which trim you have and which wheel setup came with it.
