The 2024 Toyota Trucks Grand Highlander was designed as a larger, family-focused three-row SUV with a strong emphasis on passenger space, daily comfort, and long-distance usability. That broader footprint makes tire fitment especially important, because wheel diameter and sub-model trim both shape the correct replacement choice. This model uses two primary radial sizes, 255/55R20 and 255/65R18, depending on the specific Grand Highlander configuration. The decision is less about old-style bias-ply versus radial construction and more about matching the right size to the right trim, wheel, and intended use. Owners replacing tires should start by confirming the sub-model and wheel diameter before comparing available tire options.
Which Tire Size Is Right for The 2024 Toyota Trucks Grand Highlander
The 2024 Toyota Trucks Grand Highlander uses two primary tire sizes, and the correct one depends on the specific sub-model and wheel diameter. Both are radial sizes, but one fits an 18-inch wheel and the other fits a 20-inch wheel, so confirming the exact trim and wheel setup comes first. Once that is established, the next step is choosing the tire that best suits everyday driving, replacement priorities, and overall fitment needs.
Fit(s): Hybrid Limited, Hybrid MAX Limited, Hybrid MAX Platinum, Limited, and Platinum
Construction: Radial|Rim: 20 in
255/55R20 is a metric radial size in which 255 refers to the section width in millimeters, 55 is the aspect ratio, R indicates radial construction, and 20 is the wheel diameter in inches. On the 2024 Toyota Trucks Grand Highlander, this size is used on 20-inch-wheel configurations and aligns with trims that carry the larger wheel package. Its overall dimensions remain very close to the 18-inch fitment, but the lower-profile sidewall changes the tire's presentation and wheel relationship. This size should be chosen only after confirming that the vehicle actually has the 20-inch wheel setup.
255/65R18 is a metric radial size where 255 identifies nominal section width in millimeters, 65 is the aspect ratio, R marks radial construction, and 18 identifies the wheel diameter in inches. For the 2024 Toyota Trucks Grand Highlander, this size is used on 18-inch-wheel trims and serves as a distinct primary fitment rather than an interchangeable alternative to the 20-inch size. Even though its overall diameter is very similar to the 20-inch fitment, wheel diameter remains the deciding factor. This is the correct starting point for Grand Highlander trims equipped with 18-inch wheels.
2024 Toyota Trucks Grand Highlander Sub-Model Tires
Tire fitment for the 2024 Toyota Trucks Grand Highlander varies by sub-model, so identifying the exact trim matters before replacing tires. Some versions use 18-inch-wheel fitment, while others use a 20-inch-wheel setup, and the two sizes should not be treated as the same choice.

Frequently Asked Questions
These FAQs focus on the exact tire sizes used on the 2024 Toyota Trucks Grand Highlander, how trim level affects fitment, and what to check before replacing tires or driving on a fresh set.
Tire Size & Fitment
What tire size fits a 2024 Toyota Trucks Grand Highlander?
The 2024 Toyota Trucks Grand Highlander uses either 255/55R20 or 255/65R18, depending on the specific sub-model. Both are radial tire sizes, but they fit different wheel diameters, so they are separate primary fitments rather than interchangeable starting points.
The first step is identifying the exact Grand Highlander trim and confirming whether the vehicle has 18-inch or 20-inch wheels. Even though the two sizes are very close in overall diameter, the wheel diameter must match the tire size, and any replacement should also be checked for clearance and compatibility with the current wheel setup.
What size rim does a 2024 Toyota Trucks Grand Highlander use?
A 2024 Toyota Trucks Grand Highlander uses either an 18-inch or 20-inch rim, depending on the sub-model. The 255/65R18 tire fits the 18-inch setup, while the 255/55R20 tire fits the 20-inch setup.
Wheel diameter is the key fitment checkpoint on this vehicle because the two tire sizes are tied directly to different trims. Looking at the wheel itself, the existing tire sidewall, or the vehicle placard can help confirm what is on the SUV before replacing tires, especially if the wheels may have been changed after delivery.
Do all 2024 Toyota Trucks Grand Highlander sub-models use the same tire size?
No, 2024 Toyota Trucks Grand Highlander sub-models do not all use the same tire size. XLE and Hybrid XLE models use 255/65R18, while Limited, Platinum, Hybrid Limited, Hybrid MAX Limited, and Hybrid MAX Platinum models use 255/55R20.
That means trim level matters before any tire purchase is made. A buyer should confirm the exact sub-model and verify the wheel diameter on the vehicle, because moving between the 18-inch and 20-inch fitments is not simply a matter of choosing a similar overall tire height.
Choosing the Right Tire
What should I consider when choosing a 255/55R20 tire for a 2024 Toyota Trucks Grand Highlander?
A 255/55R20 tire for a 2024 Toyota Trucks Grand Highlander should match the vehicle's 20-inch wheel setup and be selected with the correct size as the first priority. This size is used on several higher-trim Grand Highlander models, so staying with the proper metric radial size keeps the fitment aligned with that configuration.
After confirming the size, compare the tire's intended road use, construction details, and overall compatibility with the vehicle's wheel and suspension setup. It is also wise to check that the SUV has not been fitted with aftermarket wheels or altered ride height, since either change can affect clearance even when the tire size itself appears correct.
What should I consider when choosing a 255/65R18 tire for a 2024 Toyota Trucks Grand Highlander?
A 255/65R18 tire is the correct starting size for 2024 Toyota Trucks Grand Highlander trims equipped with 18-inch wheels, including XLE and Hybrid XLE configurations. The main priority is keeping the proper metric radial size that matches the vehicle's wheel diameter and trim-specific fitment.
Once the wheel size is confirmed, look at how the vehicle is actually used, including family hauling, commuting, and longer road trips. Tire replacement should also account for wheel condition, suspension health, and any non-stock changes, because proper fitment depends on more than the sidewall size alone.
How do I choose between the available tires for a 2024 Toyota Trucks Grand Highlander?
The right way to choose tires for a 2024 Toyota Trucks Grand Highlander is to start with the exact trim and wheel diameter, then stay within the proper primary size for that setup. This vehicle does not present a bias-ply-versus-radial decision, since its original fitments are modern radial sizes.
From there, compare tires based on how the Grand Highlander is driven and how closely the replacement matches the current wheel configuration. Daily highway use, passenger load, and any wheel or suspension changes are all relevant, and those practical checks matter more than trying to cross-shop the 18-inch and 20-inch fitments against each other.
Restoration & Appearance
Does correct tire fitment matter for a 2024 Toyota Trucks Grand Highlander restoration or factory-style presentation?
Correct tire fitment still matters on a 2024 Toyota Trucks Grand Highlander, even though the concern is less about vintage restoration and more about preserving the vehicle's intended modern appearance and stance. Using the proper 255/55R20 or 255/65R18 size keeps the relationship between tire sidewall, wheel diameter, and body proportions consistent with the trim.
That is especially important if the goal is a clean, factory-style presentation rather than a modified look. Owners should confirm the exact sub-model and wheel package first, because the Grand Highlander's 18-inch and 20-inch fitments create noticeably different visual balance even though their overall tire diameters are very close.
How does tire construction affect the appearance of a 2024 Toyota Trucks Grand Highlander?
Tire construction is straightforward on the 2024 Toyota Trucks Grand Highlander because its primary fitments are radial sizes in both available applications. The visible appearance difference comes more from the wheel-and-sidewall combination of 255/65R18 versus 255/55R20 than from any bias-ply-versus-radial decision.
That means the trim level and wheel diameter shape the vehicle's presentation more than construction type does. An 18-inch setup shows a taller sidewall, while a 20-inch setup presents more wheel and less sidewall, so staying with the correct size helps maintain the look intended for that specific Grand Highlander configuration.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2024 Toyota Trucks Grand Highlander?
Yes, modifications can affect tire fitment on a 2024 Toyota Trucks Grand Highlander. Aftermarket wheels, changes in wheel width or offset, suspension lowering or lifting, and body modifications can all alter the space available for the original 255/55R20 or 255/65R18 tire sizes.
Any Grand Highlander that no longer has its original wheel or suspension setup should be checked carefully before replacement tires are installed. Clearance at full steering lock, suspension travel, and the actual wheel diameter on the vehicle all deserve attention, because a correct size on paper can still create issues on a modified SUV.
What should I inspect before driving a 2024 Toyota Trucks Grand Highlander on new tires?
Before driving a 2024 Toyota Trucks Grand Highlander on new tires, inspect the wheel diameter, verify the installed size, and make sure the tires are inflated properly for the vehicle's use. It is also smart to look over the wheels, valve stems, and visible suspension and brake components while the tires are being replaced.
A short check for rubbing, unusual noise, or steering irregularities after installation can help catch fitment problems early. Tire pressure should be monitored closely during the first drives, and any vibration, persistent air loss, or clearance concern deserves prompt attention before the SUV is used for longer trips.
How often should tires on a 2024 Toyota Trucks Grand Highlander be inspected?
Tires on a 2024 Toyota Trucks Grand Highlander should be inspected regularly rather than waiting for an obvious problem. Routine checks should include tread wear, sidewall condition, visible cuts or bulges, and any signs of uneven wear that could point to alignment, inflation, or suspension concerns.
Monthly pressure checks are a good habit, especially on a family-oriented SUV that may see changing passenger and cargo loads. It also helps to inspect the tires before longer drives, because catching air loss, damage, or abnormal wear early is one of the simplest ways to protect both tire life and road-use confidence.
