The 2020 Toyota Trucks 4Runner carries forward a long-running body-on-frame SUV formula that appeals to owners who want real utility, traditional truck-based durability, and genuine off-road character. Even within this modern 4Runner lineup, tire fitment is not one-size-fits-all. This model uses either 245/60R20 or 265/70R17 radial tires, depending on the sub-model and wheel package. That makes the main decision less about tire construction and more about confirming the exact trim, wheel diameter, and intended use. Street-oriented 20-inch fitment and taller-sidewall 17-inch fitment serve different purposes, so selection should match the vehicle’s actual setup and how it is driven.
Which Tire Size Is Right for The 2020 Toyota Trucks 4Runner
The 2020 Toyota Trucks 4Runner uses two primary tire sizes, and the correct one depends on the specific sub-model and wheel diameter. Both are radial fitments, but they are built around different rims, so the first step is confirming whether the vehicle has 17-inch or 20-inch wheels. Once that is settled, the real comparison becomes tire type, load specification, sidewall style, and how the tire suits daily driving or more rugged use.
245/60R20 is a metric radial size in which 245 identifies the nominal section width in millimeters, 60 is the aspect ratio, R indicates radial construction, and 20 is the wheel diameter in inches. On the 2020 Toyota Trucks 4Runner, this size is tied to the 20-inch-wheel sub-models rather than the 17-inch off-road-oriented configurations. Its sizing format reflects a modern SUV fitment with a lower-profile sidewall than the 17-inch alternative. Choosing this size starts with confirming the actual wheel package on the vehicle, especially if wheels have ever been changed from the original trim setup.
265/70R17 is a metric radial size where 265 is the nominal section width in millimeters, 70 is the aspect ratio, R marks radial construction, and 17 is the wheel diameter in inches. This is the tire size used across most 2020 Toyota Trucks 4Runner sub-models, and the available products here center on BFGoodrich All-Terrain T/A KO2 tires with raised white letter sidewalls. Those choices also differ in load specification, weight, and operating pressure. This size is the one to evaluate when the 4Runner has 17-inch wheels and the owner wants a tire with a more truck-oriented, all-terrain presentation.
Sub-model fitment matters on the 2020 Toyota Trucks 4Runner because the lineup splits between 20-inch and 17-inch wheel packages. Identifying the exact trim is the quickest way to narrow the correct tire size before comparing tire style, load specification, or intended road and trail use.

2020 Toyota Trucks 4Runner Limited
The 2020 Toyota Trucks 4Runner Limited uses the 245/60R20 radial tire size, which places it in the 20-inch-wheel group rather than the 17-inch configurations. Tire selection here begins with confirming that the vehicle still has its 20-inch wheels and then choosing a tire that matches the intended balance of appearance, road manners, and everyday SUV use.
The 2020 Toyota Trucks 4Runner Nightshade also uses the 245/60R20 radial tire size, sharing the same basic fitment pattern as the other 20-inch-wheel version in this lineup. That makes wheel-diameter confirmation especially important before shopping, particularly on a used vehicle where wheels may have been swapped.
The 2020 Toyota Trucks 4Runner SR5 uses the 265/70R17 radial tire size found across most of the 17-inch-wheel sub-models. This fitment opens the door to more truck-oriented tire choices, so selection often comes down to the vehicle’s real use, sidewall preference, and the load specification that best matches the setup.
The 2020 Toyota Trucks 4Runner SR5 Premium uses the same 265/70R17 radial size as the standard SR5 and several other trims in the range. That keeps fitment straightforward as long as the vehicle still carries 17-inch wheels, after which the main comparison becomes tread character, sidewall look, and tire specification.
The 2020 Toyota Trucks 4Runner TRD Off-Road uses 265/70R17 radial tires, placing it with the 17-inch-wheel group rather than the Limited and Nightshade models. Tire selection should focus on maintaining the correct size while comparing all-terrain-oriented product details, wheel compatibility, and how the vehicle is actually driven on and off pavement.
The 2020 Toyota Trucks 4Runner TRD Off-Road Premium also uses 265/70R17 radial tires on 17-inch wheels. For this sub-model, the practical decision is usually not the size itself but which tire specification best suits trail use, daily driving, and the vehicle’s present wheel and suspension condition.
The 2020 Toyota Trucks 4Runner TRD Pro uses the 265/70R17 radial size, keeping it aligned with the broader 17-inch-wheel group in this model range. Buyers should still verify the actual wheel setup and compare tire specifications carefully, especially if the vehicle has been modified for off-road use or upgraded with different wheels.
The 2020 Toyota Trucks 4Runner Venture uses 265/70R17 radial tires, matching the fitment found on most non-20-inch trims in the lineup. That makes size selection straightforward once the sub-model is confirmed, leaving the buyer free to compare all-terrain product details and the tire’s visual character.
The tire sizes listed on this page assume factory-standard vehicle configuration. The following modifications may affect tire fitment and are not reflected in this guide:
Suspension changes (lowering, lift kits, spring replacements)
Body alterations (fender modifications, custom bodywork)
If your vehicle has been modified from factory specifications, verify tire clearance before purchase.
Best 2020 Toyota Trucks 4Runner Tires for Sale
Available product choices for the 2020 Toyota Trucks 4Runner focus on 265/70R17 tires from BFGoodrich in the All Terrain T/A KO2 series. These options share radial construction, raised white letter sidewalls, and 17-inch rim fitment, while differing in load specification, weight, and operating pressure.
Tire questions for the 2020 Toyota Trucks 4Runner usually come down to trim-specific sizing, 17-inch versus 20-inch wheel fitment, all-terrain tire selection, and basic checks before daily use or longer trips. The FAQs below focus on those exact issues.
Tire Size & Fitment
What tire size fits a 2020 Toyota Trucks 4Runner?
The 2020 Toyota Trucks 4Runner uses either 245/60R20 or 265/70R17 tires. Limited and Nightshade models use 245/60R20, while SR5, SR5 Premium, TRD Off-Road, TRD Off-Road Premium, TRD Pro, and Venture models use 265/70R17.
The correct choice depends on the sub-model and the wheel diameter currently on the vehicle. A used 4Runner may have different wheels than it left the factory with, so checking the trim badge alone is not enough. Confirm the tire size on the vehicle, verify whether it has 17-inch or 20-inch wheels, and then compare tire options within that exact size.
What size rim does a 2020 Toyota Trucks 4Runner use?
A 2020 Toyota Trucks 4Runner uses either a 17-inch or 20-inch rim, depending on the sub-model. The 245/60R20 fitment is built around a 20-inch wheel, and the 265/70R17 fitment is built around a 17-inch wheel.
Rim diameter is the first fitment point to verify because a 17-inch tire cannot be mounted on a 20-inch wheel, and a 20-inch tire cannot be mounted on a 17-inch wheel. Before selecting a tire, inspect the actual wheels on the vehicle and check whether aftermarket wheels have changed the original trim-based setup.
Do all 2020 Toyota Trucks 4Runner sub-models use the same tire size?
No, the 2020 Toyota Trucks 4Runner does not use one tire size across every sub-model. Limited and Nightshade models use 245/60R20, while the rest of the listed sub-models use 265/70R17.
That split matters because the different sizes also use different wheel diameters and can lead buyers into the wrong product category if the trim is not confirmed first. Once the exact sub-model and wheel size are known, the remaining decision becomes simpler: choose the correct tire specification, sidewall style, and tread character for the way the 4Runner is driven.
Choosing the Right Tire
What should I consider when choosing a 265/70R17 tire for a 2020 Toyota Trucks 4Runner?
Start with the basics: correct size, radial construction, and compatibility with a 17-inch wheel. For the 2020 Toyota Trucks 4Runner, available 265/70R17 choices include BFGoodrich All-Terrain T/A KO2 tires, and those options differ in load specification, weight, and the pressure tied to their maximum load rating.
The practical choice depends on how the 4Runner is used. A daily-driven SUV, a heavily loaded vehicle, and a trail-focused build may not need the same tire specification even within the same size. Compare the wheel width, load figure, and sidewall presentation carefully, and make sure the selected tire suits the vehicle’s actual setup rather than just the trim name.
What sidewall styles are available for 2020 Toyota Trucks 4Runner tires?
Among the available products for this 2020 Toyota Trucks 4Runner fitment, the visible sidewall style is RWL, or raised white letter, on the 265/70R17 BFGoodrich All-Terrain T/A KO2 options. That gives the tire a more traditional truck and SUV look than a plain black sidewall.
Sidewall style is mainly an appearance decision, but it can strongly influence how the 4Runner presents visually, especially on TRD and other 17-inch-wheel models. Buyers who want a more rugged or period-truck look may prefer raised white letters, while others may want a subtler presentation. The key is choosing a sidewall style that matches the vehicle’s use and overall appearance.
What brands offer tires for the 2020 Toyota Trucks 4Runner?
Current product coverage for this 2020 Toyota Trucks 4Runner fitment includes BFGoodrich in the 265/70R17 size. The available tires are part of the All-Terrain T/A KO2 series and are offered in more than one load specification within that same size.
Brand matters less than getting the correct size and the right specification for the vehicle’s wheel and use case. Once the size is confirmed, compare the series character, sidewall appearance, and load details rather than choosing by brand name alone. That approach is especially important on SUVs that may see a mix of commuting, towing, cargo, and off-pavement driving.
Restoration & Appearance
Which tire should I choose for a period-style 2020 Toyota Trucks 4Runner?
A period-style approach on a 2020 Toyota Trucks 4Runner usually means staying with the original size format tied to the sub-model and wheel package. That means 245/60R20 for Limited and Nightshade models, or 265/70R17 for the other listed trims, rather than mixing sizes from another trim level.
Appearance is shaped not just by the dimensions, but also by the wheel diameter and sidewall character. On 17-inch models, an all-terrain tire with raised white letters creates a more traditional truck-based presentation than a plain street-oriented tire would. Keeping the correct size for the trim is the foundation before making smaller visual decisions.
How does tire construction affect the appearance of a restored 2020 Toyota Trucks 4Runner?
Tire construction is straightforward on the 2020 Toyota Trucks 4Runner because the primary fitments are radial. That means appearance differences come less from bias-ply-versus-radial considerations and more from the tire’s profile, tread style, sidewall treatment, and whether the vehicle uses the 17-inch or 20-inch wheel setup.
A 17-inch all-terrain radial with raised white letters gives the vehicle a more rugged, truck-oriented look, while a 20-inch fitment changes the visual balance through wheel size and shorter sidewall height. Buyers focused on keeping the 4Runner visually true to its trim should match the original size family first, then refine the look through tire style.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2020 Toyota Trucks 4Runner?
Yes, modifications can affect tire fitment on a 2020 Toyota Trucks 4Runner even when the tire size itself looks correct on paper. Aftermarket wheels, changes in wheel width, suspension lifts or lowering, and body or fender changes can all alter clearance and how the tire sits on the vehicle.
That matters most when a 4Runner has been built for trail use or personalized beyond its original trim setup. Check wheel diameter first, then verify wheel width, steering clearance, and room at the fender and suspension through the full range of motion. A size that suits one stock sub-model may need closer review on a modified vehicle.
What should I inspect before driving a 2020 Toyota Trucks 4Runner on new tires?
Before driving a 2020 Toyota Trucks 4Runner on new tires, inspect the wheel size, confirm the tire size matches the sub-model setup, and check inflation pressure against the tire’s intended use. It is also wise to look at bead seating, valve condition, lug torque, and any visible interference near the fenders or suspension.
A short test drive should include listening for rubbing during turns and watching for vibration or pull. Recheck pressure after the tires have settled and inspect them again after the first miles of use. That extra step is especially worthwhile on a used 4Runner where wheel changes, alignment issues, or suspension wear may already be present.
What should I check before a longer drive in a 2020 Toyota Trucks 4Runner?
Before a longer drive, check tire pressure, tread condition, and the sidewalls for cuts, cracking, or bulges. On a 2020 Toyota Trucks 4Runner, it also helps to confirm that the vehicle is wearing the correct size for its wheel package, especially if it has recently changed hands or received aftermarket wheels.
Longer trips put more heat and load into the tire, so the basics matter: proper inflation, secure wheels, and no sign of rubbing under steering or suspension movement. Take a moment to inspect the spare as well if the vehicle is used for travel or trail work. Catching a small fitment or condition issue early can prevent roadside trouble.
