The 2019 Toyota Trucks 4Runner sits in a part of the SUV market where body-on-frame toughness, everyday usability, and genuine trail capability still matter. Buyers often choose it for long-term durability, light overlanding, and the ability to balance paved-road comfort with rougher terrain. Tire fitment depends on trim, with the Limited using 245/60R20 radials and the SR5, SR5 Premium, TRD Off-Road, TRD Off-Road Premium, and TRD Pro using 265/70R17 radials. That split changes both wheel diameter and the style of tire choices available. Getting the right setup starts with matching the exact sub-model, then checking how the tire's size, load specification, and intended use fit the vehicle.
Which Tire Size Is Right for The 2019 Toyota Trucks 4Runner
Two primary tire sizes apply to the 2019 Toyota Trucks 4Runner, and the correct one depends on the exact sub-model. The key difference is not just tire width and profile, but wheel diameter as well: the Limited uses a 20-inch setup, while the other covered trims use a 17-inch setup. Before choosing a tire, confirm the trim and verify which wheels are actually on the vehicle, especially if it has been modified or had wheels swapped.
245/60R20 is a metric radial size in which 245 identifies the section width in millimeters, 60 is the aspect ratio, R denotes radial construction, and 20 is the rim diameter in inches. On the 2019 Toyota Trucks 4Runner, this size is tied to the Limited and reflects a larger-wheel fitment than the other trims. Its dimensions point to a lower-profile look compared with the 17-inch alternative while keeping a similar overall tire height. This is the size to evaluate when matching the Limited's wheel setup and preserving that trim's intended stance and rim diameter.
Fit(s): SR5, SR5 Premium, TRD Off-Road, TRD Off-Road Premium, and TRD Pro
Construction: Radial|Rim: 17 in
265/70R17 is a metric radial size where 265 is the nominal section width in millimeters, 70 is the aspect ratio, R identifies radial construction, and 17 is the wheel diameter in inches. This size applies to the SR5, SR5 Premium, TRD Off-Road, TRD Off-Road Premium, and TRD Pro, making it the core fitment for most 2019 4Runner trims covered here. Available products in this size include BFGoodrich All-Terrain T/A KO2 options with raised white letter sidewalls. It is the size to focus on when the goal is maintaining the 17-inch trim setup and comparing all-terrain-oriented tire specifications.
Sub-model fitment matters on the 2019 Toyota Trucks 4Runner because tire size changes with trim level. The Limited uses a different wheel and tire package than the SR5 and TRD variants, so identifying the exact sub-model is the first step before comparing tires.

2019 Toyota Trucks 4Runner Limited
The 2019 Toyota Trucks 4Runner Limited uses a 245/60R20 radial tire, which places it on a 20-inch wheel rather than the 17-inch setup used by the other covered trims. Tire selection here starts with confirming that larger wheel package and then choosing a tire that suits the vehicle's road use, appearance, and overall setup.
The 2019 Toyota Trucks 4Runner SR5 uses the 265/70R17 radial size shared by several other trims in the lineup. That makes tire selection more about comparing available specifications, sidewall presentation, and intended use than sorting through multiple factory size paths.
The 2019 Toyota Trucks 4Runner SR5 Premium also uses 265/70R17 radials on a 17-inch wheel setup. Buyers in this trim should focus on matching the existing wheel package and then evaluating tire characteristics such as load specification, construction details, and the type of road or trail use the vehicle sees.
The 2019 Toyota Trucks 4Runner TRD Off-Road uses the 265/70R17 radial size. Since this trim shares its fitment with several other 4Runner variants, the main decision becomes choosing the right tire within that size and confirming compatibility with the actual wheel width and vehicle use.
The 2019 Toyota Trucks 4Runner TRD Off-Road Premium stays with the 265/70R17 radial setup used across the 17-inch-wheel trims. That shared fitment keeps sizing straightforward, but it still helps to compare tire load specification, sidewall style, and wheel-width compatibility before making a final choice.
The 2019 Toyota Trucks 4Runner TRD Pro uses 265/70R17 radials rather than the Limited's 20-inch fitment. Tire selection should center on the 17-inch wheel setup already on the vehicle and on whether the tire's specification matches the 4Runner's intended road, trail, or mixed-use duty.
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 2019 Toyota Trucks 4Runner?
The 2019 Toyota Trucks 4Runner uses two primary tire sizes, depending on sub-model. The Limited uses 245/60R20, while the SR5, SR5 Premium, TRD Off-Road, TRD Off-Road Premium, and TRD Pro use 265/70R17. Both are radial tire fitments, but they are built around different wheel diameters.
That means the first step is identifying the exact trim and confirming the wheels currently on the vehicle. A 4Runner with replacement wheels may no longer match its original trim-based setup, so checking the tire size on the sidewall and measuring the wheel diameter can prevent ordering the wrong fitment.
What size rim does a 2019 Toyota Trucks 4Runner use?
Rim diameter depends on the trim. A 2019 Toyota Trucks 4Runner Limited uses a 20-inch rim with 245/60R20 tires, while the SR5, SR5 Premium, TRD Off-Road, TRD Off-Road Premium, and TRD Pro use a 17-inch rim with 265/70R17 tires.
Wheel diameter is the non-negotiable starting point because a 17-inch tire will not mount on a 20-inch wheel, and a 20-inch tire will not mount on a 17-inch wheel. Once diameter is confirmed, compare wheel width and the actual tire size already on the vehicle, especially if aftermarket wheels have been installed.
Do all 2019 Toyota Trucks 4Runner sub-models use the same tire size?
No, the 2019 Toyota Trucks 4Runner does not use one tire size across every covered sub-model. The Limited is fitted with 245/60R20, while the SR5, SR5 Premium, TRD Off-Road, TRD Off-Road Premium, and TRD Pro share the 265/70R17 size.
That split matters because it affects both the tire size and the wheel diameter. A buyer comparing tires needs to know whether the vehicle is on the Limited's 20-inch package or the 17-inch package used by the other trims, then confirm that the current wheel and tire setup still matches that trim configuration.
Choosing the Right Tire
What should I consider when choosing a 265/70R17 tire for a 2019 Toyota Trucks 4Runner?
Start with the basics: the 265/70R17 size applies to the SR5, SR5 Premium, TRD Off-Road, TRD Off-Road Premium, and TRD Pro, so it is only correct for those trims or for vehicles currently using that 17-inch wheel setup. From there, compare the tire's load specification, radial construction details, rim-width compatibility, and overall product character.
Available 265/70R17 choices include BFGoodrich All-Terrain T/A KO2 tires with different load ratings and weights, so the better comparison is not just brand name but how each version suits the vehicle's use. A mostly street-driven 4Runner and one that regularly carries gear or sees rougher terrain may call for different priorities.
What sidewall styles are available for 2019 Toyota Trucks 4Runner tires?
Among the available products for this 2019 Toyota Trucks 4Runner fitment, the visible sidewall style shown in 265/70R17 is RWL, or raised white letter. That style gives the tire a more traditional truck and SUV presentation than a plain black sidewall, while staying within the correct size for the covered 17-inch-wheel trims.
Sidewall style should still be a secondary decision after confirming the correct trim-based size. Once the vehicle is matched to the proper tire size and wheel diameter, sidewall appearance becomes a useful way to align the tire with the 4Runner's look, whether the goal is a more understated finish or a more rugged visual statement.
What brands offer tires for the 2019 Toyota Trucks 4Runner?
The available products shown for the 2019 Toyota Trucks 4Runner's 265/70R17 fitment are from BFGoodrich. Those options are part of the All-Terrain T/A KO2 series and are offered with different load specifications in the same basic size.
Brand alone is only part of the decision. Once the correct trim and tire size are confirmed, compare the specific product version, including load capacity, pressure relationship, weight, rim-width range, and sidewall style. That approach gives a more useful match for how the 4Runner is driven than choosing by brand name alone.
Restoration & Appearance
Does correct tire fitment matter for a 2019 Toyota Trucks 4Runner restoration or preservation project?
Yes, correct tire fitment still matters on a 2019 Toyota Trucks 4Runner, even though it is a much newer vehicle than a traditional collector car. The Limited's 245/60R20 setup and the 265/70R17 fitment used by the other trims create different visual proportions, so keeping the proper size helps preserve the trim's intended stance and wheel-to-tire relationship.
That is especially relevant when a preservation-minded owner wants the vehicle to remain close to its original presentation. If originality is important, verify the current wheels and tire size against the exact sub-model before making changes, because a wheel swap can alter the appearance as much as the tire itself.
Which sidewall style suits a period-appropriate 2019 Toyota Trucks 4Runner look?
For the available 265/70R17 products on the 2019 Toyota Trucks 4Runner, the visible sidewall style is raised white letter. That treatment works naturally with the 4Runner's truck-based character and gives the vehicle a more assertive, utility-oriented look than a plain black sidewall would.
Appearance should still follow correct fitment, not replace it. The best visual match starts with the proper trim-based tire size and wheel diameter, then uses sidewall treatment to fine-tune the look. Owners seeking a highly original presentation should also compare against trim-specific photos, window sticker information, or marque references before changing style.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2019 Toyota Trucks 4Runner?
Yes, modifications can affect tire fitment on a 2019 Toyota Trucks 4Runner. Aftermarket wheels, changes in wheel width, offset differences, suspension lifts, leveling kits, or body trimming can all alter how a tire sits in the wheel opening and how much room it has during steering and suspension movement.
That is why the current setup matters as much as the original trim specification. A 4Runner that started with 265/70R17 or 245/60R20 may now have different clearance requirements than stock, so check wheel diameter, wheel width, turning clearance, and suspension travel before assuming any tire choice will behave the same way.
What should I inspect before driving a 2019 Toyota Trucks 4Runner on new tires?
Before road use, inspect inflation pressure, lug nut torque, tread and sidewall condition, and clearance at full steering lock. It also helps to confirm that the tire size matches the vehicle's actual wheel diameter and that there is no rubbing against suspension components, fender liners, or bodywork once the vehicle is on the ground.
A short local drive is a smart follow-up because it gives time to check for vibration, air loss, or contact marks after the tires have settled in. On a 4Runner that sees mixed road and trail use, rechecking pressure and visual condition regularly is especially important because impacts and debris can affect long-term tire health.
How often should tires on a 2019 Toyota Trucks 4Runner be inspected?
Tires on a 2019 Toyota Trucks 4Runner should be inspected regularly rather than only at replacement time. A quick visual check before longer drives and a more deliberate inspection during routine service helps catch uneven wear, cuts, cracking, bulges, punctures, and slow air loss before they become larger problems.
That habit matters even more on a vehicle that may alternate between highway driving and rougher surfaces. Checking tread wear, sidewall condition, and pressure at consistent intervals also helps reveal alignment issues, damage from trail use, or changes caused by wheel and suspension modifications that could affect fitment over time.
