The 2019 Toyota Trucks Highlander sits in the modern family-crossover market as a three-row SUV built for daily road use, long trips, and all-around practicality. Buyers looking at this exact model usually are not deciding between vintage-style constructions, but between the correct modern radial size for their specific trim and wheel package. This Highlander uses either 245/60R18 or 245/55R19 radial tires, depending on sub-model. That makes trim identification and wheel-diameter confirmation the key first steps before comparing tire choices. Once the correct size is pinned down, the focus shifts to everyday priorities such as maintaining the intended stance, preserving ride quality, and confirming compatibility if wheels have ever been changed.
Which Tire Size Is Right for The 2019 Toyota Trucks Highlander
The 2019 Toyota Trucks Highlander uses two primary tire sizes, and the correct one depends on the exact sub-model and wheel diameter. Both are modern radial fitments, but one size is mounted on an 18-inch rim and the other on a 19-inch rim. Before comparing tire choices, confirm the trim level and make sure the vehicle still has the correct wheel diameter, especially if aftermarket wheels have been installed.
Fit(s): Hybrid LE, Hybrid XLE, LE, LE Plus, and XLE
Construction: Radial|Rim: 18 in
245/60R18 is a metric radial size in which 245 identifies the section width in millimeters, 60 is the aspect ratio, R denotes radial construction, and 18 is the rim diameter in inches. On the 2019 Toyota Trucks Highlander, this size serves trims equipped with 18-inch wheels and reflects a modern road-oriented tire format. Its practical role is straightforward: it preserves the intended fitment for Highlander sub-models built around the 18-inch package. Choosing this size starts with confirming the correct trim and wheel diameter, then matching the tire to the vehicle's actual wheel setup and everyday use.
Fit(s): Hybrid Limited, Hybrid Limited Platinum, Limited, Limited Platinum, and SE
Construction: Radial|Rim: 19 in
245/55R19 is also a metric radial size, with a 245-millimeter section width, a 55-series profile, radial construction, and a 19-inch rim diameter. For the 2019 Toyota Trucks Highlander, this size applies to sub-models equipped with the 19-inch wheel package rather than the 18-inch setup. The slightly lower profile is part of the size format, but the main buying decision is still trim-specific fitment, not style conversion. Use this size only after confirming that the Highlander's wheels are the correct 19-inch diameter and that no previous wheel or suspension changes have altered clearance.
Tire fitment on the 2019 Toyota Trucks Highlander varies by sub-model, so identifying the exact trim matters before choosing a tire. The main split is between 18-inch and 19-inch wheel packages, which determines whether the vehicle uses 245/60R18 or 245/55R19.

Frequently Asked Questions
These FAQs focus on the 2019 Toyota Trucks Highlander's two trim-dependent tire sizes, the difference between 18-inch and 19-inch wheel fitments, and the practical checks that matter before replacement or regular road use.
Tire Size & Fitment
What tire size fits a 2019 Toyota Trucks Highlander?
A 2019 Toyota Trucks Highlander uses either 245/60R18 or 245/55R19, depending on the sub-model. LE, LE Plus, XLE, Hybrid LE, and Hybrid XLE use 245/60R18, while SE, Limited, Limited Platinum, Hybrid Limited, and Hybrid Limited Platinum use 245/55R19.
The key is not choosing between two interchangeable sizes, but matching the tire to the exact trim and wheel diameter on the vehicle. A used Highlander may already have different wheels installed, so checking the tire placard, current wheel size, and actual trim package helps prevent ordering the wrong fitment.
What size rim does a 2019 Toyota Trucks Highlander use?
The 2019 Toyota Trucks Highlander uses either an 18-inch rim or a 19-inch rim, depending on sub-model. The 245/60R18 tire is paired with an 18-inch wheel, while the 245/55R19 tire is paired with a 19-inch wheel.
Wheel diameter should be confirmed before replacing tires because the two Highlander fitments are tied directly to different trim levels. Looking only at the vehicle year and model is not enough if the SUV has aftermarket wheels or if a previous owner changed the original wheel package.
Why does the 2019 Toyota Trucks Highlander have more than one tire size?
The 2019 Toyota Trucks Highlander has more than one tire size because different sub-models were equipped with different wheel packages. Some trims use 18-inch wheels with 245/60R18 tires, while others use 19-inch wheels with 245/55R19 tires.
That means tire selection starts with trim and wheel confirmation rather than preference alone. The two sizes are close in overall diameter, but they are built around different rim diameters, so the correct choice depends on how the specific Highlander was equipped and whether that setup has remained unchanged.
Choosing the Right Tire
What should I consider when choosing a tire for a 2019 Toyota Trucks Highlander?
Start with the correct trim-specific size: 245/60R18 for the Highlander's 18-inch wheel package or 245/55R19 for the 19-inch package. Both are modern radial sizes, so the first decision is fitment accuracy rather than construction type.
After size is confirmed, look at how the Highlander is actually used. Daily commuting, family travel, and highway driving all place importance on staying with the proper dimensions, maintaining clearance, and choosing a tire that matches the wheel diameter and overall vehicle setup without introducing avoidable fitment issues.
How do I choose between the available 245/60R18 and 245/55R19 tires for a 2019 Toyota Trucks Highlander?
The choice between 245/60R18 and 245/55R19 is not based on preference alone because each size belongs to a different Highlander trim and wheel diameter. The right tire is the one that matches the vehicle's existing 18-inch or 19-inch wheel package.
Once the correct size is established, compare tires within that exact size rather than across both sizes. Keeping the intended dimensions helps preserve proper clearance and avoids complications that can come from mounting a tire built for a different rim diameter than the one currently on the vehicle.
What does 245/60R18 mean on a 2019 Toyota Trucks Highlander?
On a 2019 Toyota Trucks Highlander, 245/60R18 means the tire is 245 millimeters wide, has a 60-series aspect ratio, uses radial construction, and fits an 18-inch rim. It is the correct size for certain Highlander trims equipped with the 18-inch wheel package.
Understanding the code helps separate width, profile, and wheel fitment, which is especially useful when shopping for replacements. The final number is the most critical starting point because it determines wheel diameter, and mounting a tire intended for a different rim size is not an acceptable substitute.
Restoration & Appearance
Does correct tire fitment matter for a 2019 Toyota Trucks Highlander restoration?
Correct tire fitment still matters on a 2019 Toyota Trucks Highlander, even though it is a newer vehicle rather than a vintage restoration candidate. Matching the trim-specific size preserves the intended relationship between the tire, wheel, and body, which affects both appearance and everyday drivability.
A clean, original-style presentation starts with using the proper 245/60R18 or 245/55R19 size for the exact sub-model. Buyers aiming to keep the Highlander close to its original configuration should also verify that the wheels themselves match the trim and have not been changed during previous ownership.
How does tire size affect the appearance of a 2019 Toyota Trucks Highlander?
Tire size affects the 2019 Toyota Trucks Highlander's overall stance because each size is paired with a specific wheel diameter and profile. The 245/60R18 fitment presents the Highlander on an 18-inch wheel, while 245/55R19 pairs with a 19-inch wheel and a slightly shorter sidewall profile.
Appearance should still follow fitment, not the other way around. Keeping the tire size matched to the correct trim preserves the intended visual balance, while switching to a size built for a different rim diameter can create unnecessary fitment problems and make the SUV look mismatched.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2019 Toyota Trucks Highlander?
Yes, modifications can affect tire fitment on a 2019 Toyota Trucks Highlander. Aftermarket wheels, suspension changes, lowering or lifting, and body alterations can all change the space available around a 245/60R18 or 245/55R19 tire, even when the size itself matches the original trim.
Any Highlander that has been modified should be checked for wheel diameter, wheel width, offset, and clearance at the fender and suspension before replacement tires are selected. Those details matter just as much as the size printed on the sidewall when trying to avoid rubbing or mismatch problems.
What should I inspect before driving a 2019 Toyota Trucks Highlander on new tires?
Before driving a 2019 Toyota Trucks Highlander on new tires, inspect tire pressure, wheel lug torque, sidewall condition, tread seating, and visible clearance around the fenders and suspension. It is also wise to confirm that all four tires match the correct trim-specific size and rim diameter.
A short visual check after installation can catch problems early, especially on a used vehicle with an uncertain wheel history. Look for uneven spacing, any contact during steering, and signs of air loss after the first few drives so the Highlander starts service on a stable and properly matched setup.
How often should tires on a 2019 Toyota Trucks Highlander be inspected?
Tires on a 2019 Toyota Trucks Highlander should be inspected regularly rather than only at replacement time. Frequent checks for pressure loss, uneven wear, cuts, sidewall damage, tread condition, and embedded debris help catch developing problems before they turn into ride or safety issues.
Monthly visual inspections are a sensible habit, and extra attention is worthwhile before longer highway trips or after impacts with potholes or curbs. Because this Highlander uses trim-specific 18-inch or 19-inch fitments, inspection is also a good time to confirm that the tires remain properly matched across the vehicle.
