The 2015 Toyota Trucks 4Runner sits squarely in the modern body-on-frame SUV category, balancing everyday road use with the durability and stance that have kept the 4Runner popular with owners who still value true truck-based utility. Tire fitment matters more than usual here because this model uses two distinct radial sizes depending on sub-model: 245/60R20 or 265/70R17. That means the first decision is not brand or tread style, but confirming whether the truck is a Limited or one of the 17-inch-wheel trims. Once that is settled, the focus shifts to wheel diameter, intended use, and keeping the tire size aligned with the vehicle's actual setup.
Which Tire Size Is Right for The 2015 Toyota Trucks 4Runner
The 2015 Toyota Trucks 4Runner uses two primary tire sizes, and the correct one depends on the sub-model and wheel diameter. Limited models use a 20-inch radial fitment, while SR5, TRD Pro, and Trail models use a 17-inch radial fitment. Before selecting a tire, confirm the exact trim and wheel size currently on the truck, especially if wheels have ever been changed.
245/60R20 is a metric radial size in which 245 identifies the nominal section width in millimeters, 60 is the aspect ratio, R denotes radial construction, and 20 is the wheel diameter in inches. On the 2015 Toyota Trucks 4Runner, this size belongs to the Limited sub-model and is tied to a 20-inch wheel setup. Its role is not interchangeable with the 17-inch fitment simply because overall diameter is similar. Buyers considering this size should verify that the truck still carries its correct 20-inch wheels before comparing tire choices.
265/70R17 is a metric radial size with a 265-millimeter nominal section width, a 70-series profile, radial construction, and a 17-inch rim diameter. This is the primary fitment for the 2015 Toyota Trucks 4Runner SR5, TRD Pro, and Trail sub-models, making it the key size for buyers shopping those trims. Available products in this size include BFGoodrich All-Terrain T/A KO2 options with raised white letter sidewalls and different load capacities. That makes this size especially relevant for owners who want to balance trim-correct fitment with intended road or off-road use.
Sub-model fitment matters on the 2015 Toyota Trucks 4Runner because tire size changes with trim. The Limited uses a different wheel and tire package than the SR5, TRD Pro, and Trail, so identifying the exact sub-model is the first step before choosing a replacement tire.

2015 Toyota Trucks 4Runner Limited
The 2015 Toyota Trucks 4Runner Limited uses the 245/60R20 radial size, which places it on a 20-inch wheel setup rather than the 17-inch arrangement used on other trims. Tire selection here starts with confirming that the truck still has the correct wheel diameter before comparing replacement options.
The 2015 Toyota Trucks 4Runner SR5 uses the 265/70R17 radial size. That keeps tire selection centered on the 17-inch fitment and allows the buyer to compare available products in that size based on load rating, sidewall presentation, and intended use.
The 2015 Toyota Trucks 4Runner TRD Pro uses the 265/70R17 radial size. For this sub-model, the practical decision is less about identifying size variation and more about choosing a tire in the proper 17-inch fitment that suits the truck's current wheel setup and driving needs.
The 2015 Toyota Trucks 4Runner Trail uses the 265/70R17 radial size. Buyers shopping this sub-model should stay focused on the 17-inch radial fitment first, then compare available tire options by load specification, tread intent, and overall compatibility with the vehicle's use.
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.

Tire Size & Fitment
What tire size fits a 2015 Toyota Trucks 4Runner?
The 2015 Toyota Trucks 4Runner uses two tire sizes depending on sub-model. The Limited uses 245/60R20, while the SR5, TRD Pro, and Trail use 265/70R17. Both are radial fitments, but they are tied to different wheel diameters, so the correct size starts with the exact trim and wheel package on the truck.
That means tire selection should begin by confirming whether the vehicle has 17-inch or 20-inch wheels. Even though the two sizes have similar overall diameter, they are not the same fitment. If the 4Runner has aftermarket wheels or a changed suspension setup, check the current wheel size and clearance before choosing a replacement tire.
What size rim does a 2015 Toyota Trucks 4Runner use?
A 2015 Toyota Trucks 4Runner uses either a 17-inch or 20-inch rim, depending on sub-model. The Limited uses a 20-inch rim with 245/60R20 tires, while the SR5, TRD Pro, and Trail use a 17-inch rim with 265/70R17 tires. Rim diameter is a primary fitment point on this model because the tire sizes are built around different wheel packages.
Checking the actual wheel diameter on the truck is essential before ordering tires, especially on a used SUV. A changed wheel package can make the trim badge less useful than the wheel itself. It also helps to confirm wheel width and inspect for any aftermarket changes that could affect tire choice, sidewall shape, or clearance.
Do all 2015 Toyota Trucks 4Runner sub-models use the same tire size?
No, the 2015 Toyota Trucks 4Runner does not use one tire size across every sub-model. The Limited uses 245/60R20, while the SR5, TRD Pro, and Trail use 265/70R17. The difference is tied to the wheel diameter and trim-specific setup, so the correct tire depends on the exact version of the vehicle.
This matters because a buyer cannot treat every 2015 4Runner tire search the same way. The first step is confirming the sub-model and then verifying the wheel size currently installed. Once that is settled, the tire decision becomes much simpler, since the buyer can focus on the correct construction, available products, and the vehicle's intended driving use.
Choosing the Right Tire
What should I consider when choosing a 265/70R17 tire for a 2015 Toyota Trucks 4Runner?
Start with the basics: 265/70R17 is the correct radial size for the 2015 Toyota Trucks 4Runner SR5, TRD Pro, and Trail. From there, compare the tire's intended use, load capacity, and wheel compatibility. Available BFGoodrich All-Terrain T/A KO2 options in this size share the same basic fitment but differ in load specification and weight.
The practical choice depends on how the truck is used and whether the current wheels match the tire's rim-width requirement. A lightly driven street truck may have different needs than one carrying gear or seeing rougher terrain. Matching the correct size is only the first step; the remaining decision is about selecting the version that suits the vehicle's setup.
What sidewall styles are available for 2015 Toyota Trucks 4Runner tires?
Among the available products for the 2015 Toyota Trucks 4Runner, the 265/70R17 options use an RWL sidewall, meaning raised white letter styling. That gives the tire a more traditional truck and SUV presentation than a plain black sidewall. Sidewall style does not change the underlying tire size, but it does affect the look of the vehicle.
For many 4Runner owners, sidewall treatment is part of the overall character of the truck, especially on a more rugged 17-inch-wheel setup. It is still important to choose the correct size and load specification first. After that, sidewall style becomes an appearance decision that should be balanced with the truck's intended use and wheel package.
What tire series are available for the 2015 Toyota Trucks 4Runner?
The available 265/70R17 products for the 2015 Toyota Trucks 4Runner are offered in the BFGoodrich All Terrain TA KO2 series. That keeps the product comparison focused less on multiple series names and more on the differences within the same all-terrain family, such as load rating and other related specifications.
That kind of lineup simplifies the buying process because the main variables are not style changes across unrelated series. Instead, the buyer should look closely at how each version matches the truck's use, wheel specification, and load needs. On a vehicle like the 4Runner, the correct fitment matters first, and then the product details help narrow the final choice.
Restoration & Appearance
Which tire should I choose for a period-style 2015 Toyota Trucks 4Runner?
A period-style choice for a 2015 Toyota Trucks 4Runner starts with keeping the correct trim-specific size in place. That means 245/60R20 for a Limited and 265/70R17 for an SR5, TRD Pro, or Trail. Staying with the proper wheel diameter and size preserves the basic proportions and stance that belong with the truck's original model-year appearance.
Appearance decisions can then move to tread character and sidewall presentation rather than changing the fitment itself. On the available 265/70R17 products, raised white letter styling adds a more traditional truck look. Anyone pursuing exact showroom-era detail should also compare the vehicle against original sales literature, window-sticker records, or marque-specific references.
Does correct tire fitment matter for a 2015 Toyota Trucks 4Runner restoration?
Yes, correct tire fitment matters on a 2015 Toyota Trucks 4Runner restoration because the truck uses different sizes across its sub-model range. A Limited restored on 245/60R20 presents differently from an SR5, TRD Pro, or Trail on 265/70R17. The right tire size helps keep the wheel-to-body relationship and overall stance consistent with the vehicle's trim-specific setup.
That does not mean every available tire in the correct size will look the same, since sidewall styling and tread type can still change the visual result. The safest approach is to confirm the original wheel diameter for the sub-model first, then choose a tire whose size and appearance support the kind of finished presentation the restoration is meant to achieve.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2015 Toyota Trucks 4Runner?
Yes, modifications can affect tire fitment on a 2015 Toyota Trucks 4Runner even when the tire size itself is correct for the model. Aftermarket wheels, changes in wheel width, altered offset, suspension lifts, and other chassis changes can all influence how a tire sits in the wheel opening and how much clearance remains during steering or suspension movement.
That is why the current setup matters as much as the original trim specification. A Limited converted to different wheels or an SR5 running a changed suspension should be checked carefully before replacement. Confirm actual wheel diameter, inspect available clearance, and look for any rubbing marks so the next tire choice matches the vehicle as it sits today.
What should I inspect before driving a 2015 Toyota Trucks 4Runner on new tires?
Before driving a 2015 Toyota Trucks 4Runner on new tires, inspect the wheels for damage, confirm the tire size matches the trim and wheel diameter, and check that inflation is set appropriately for the tire installed. It also helps to look over the suspension and steering components so the new tires are not being asked to run on a worn or unstable foundation.
A short road check is useful after installation to make sure there is no rubbing, vibration, or unusual pull. Recheck air pressure after the first drives and look closely at sidewall and tread appearance. On a body-on-frame SUV, small alignment or wheel issues can become noticeable quickly, so catching them early helps protect the new tires.
How often should tires on a 2015 Toyota Trucks 4Runner be inspected?
Tires on a 2015 Toyota Trucks 4Runner should be inspected regularly, not just when tread appears worn. Routine checks should include air pressure, visible cuts, punctures, bulges, uneven wear, and any signs of sidewall damage. A truck that sees mixed road conditions or occasional off-pavement use deserves especially consistent inspection because impacts and debris can affect tire condition early.
It is also smart to inspect before longer drives and after any trail use, curb contact, or noticeable change in ride feel. Tire problems often show up first as small pressure loss or unusual wear rather than a sudden failure. Keeping an eye on the tires, wheels, and visible suspension condition helps the 4Runner stay ready for normal road use.
