The 2023 Mazda Trucks CX-9 sits in the modern three-row crossover category, blending family-oriented utility with a more tailored, road-focused feel than many larger SUVs. For owners shopping by exact trim, tire fitment matters because this model uses two different radial sizes depending on sub-model and wheel package. Carbon Edition, Grand Touring, Signature, and Touring Plus use 255/50R20, while Touring uses 255/60R18. That means the decision is less about vintage-style construction and more about confirming the correct rim diameter, then choosing a tire that suits the vehicle’s intended balance of appearance, ride quality, and everyday road use.
Which Tire Size Is Right for The 2023 Mazda Trucks CX-9
The 2023 Mazda Trucks CX-9 uses two primary tire sizes, and the difference comes down to sub-model and wheel diameter. Both are radial metric sizes, but one fits an 18-inch rim and the other fits a 20-inch rim. Before choosing a tire, the first step is confirming the exact sub-model or checking the wheel diameter already on the vehicle, especially if wheels have been changed since new.
Fit(s): Carbon Edition, Grand Touring, Signature, and Touring Plus
Construction: Radial|Rim: 20 in
255/50R20 is a metric radial size in which 255 identifies the section width in millimeters, 50 is the aspect ratio, R denotes radial construction, and 20 is the rim diameter in inches. On the 2023 Mazda Trucks CX-9, this size is used on higher-trim configurations equipped with 20-inch wheels. Its dimensions keep overall tire height very close to the 18-inch fitment while pairing with a larger wheel. For owners of Carbon Edition, Grand Touring, Signature, or Touring Plus models, this is the size to match before comparing tread design, ride character, and wheel compatibility.
255/60R18 is a metric radial size where 255 represents nominal section width in millimeters, 60 is the aspect ratio, R means radial construction, and 18 identifies the wheel diameter in inches. On the 2023 Mazda Trucks CX-9, this size belongs to the Touring trim fitted with 18-inch wheels. It carries essentially the same overall tire height as the 20-inch setup, but it does so with a different wheel-and-sidewall combination. That makes wheel diameter confirmation especially important before replacement, particularly on vehicles that may have seen wheel swaps or trim-level changes.
Tire fitment on the 2023 Mazda Trucks CX-9 varies by sub-model rather than following one size across the full lineup. Checking the exact trim matters because Touring uses an 18-inch fitment, while the other covered sub-models use a 20-inch setup.

Frequently Asked Questions
These FAQs focus on the exact tire sizes used on the 2023 Mazda Trucks CX-9, how fitment changes by sub-model, and what to check on wheels, tires, and vehicle condition before regular road use.
Tire Size & Fitment
What tire size fits a 2023 Mazda Trucks CX-9?
The 2023 Mazda Trucks CX-9 uses two tire sizes: 255/50R20 and 255/60R18. Carbon Edition, Grand Touring, Signature, and Touring Plus use 255/50R20, while Touring uses 255/60R18. Both are radial metric tire sizes, but they mount to different wheel diameters, so they are not interchangeable as primary fitments without matching wheels.
The practical first step is identifying the exact sub-model or measuring the wheel already on the vehicle. A CX-9 that has been fitted with aftermarket wheels or wheels from another trim may no longer match the original trim-based setup, so replacement should be based on the actual wheel diameter and current configuration.
What size rim does a 2023 Mazda Trucks CX-9 use?
A 2023 Mazda Trucks CX-9 uses either an 18-inch or 20-inch rim, depending on sub-model. Touring uses an 18-inch rim with 255/60R18 tires, while Carbon Edition, Grand Touring, Signature, and Touring Plus use a 20-inch rim with 255/50R20 tires. Both setups are radial tire applications.
Rim diameter should be confirmed before ordering replacement tires because a 20-inch tire will not mount to an 18-inch wheel, and an 18-inch tire will not mount to a 20-inch wheel. If the vehicle has been modified, check the wheel markings and current tire sidewall rather than relying only on trim assumptions.
Do all 2023 Mazda Trucks CX-9 sub-models use the same tire size?
No, the 2023 Mazda Trucks CX-9 does not use one tire size across every covered sub-model. Touring uses 255/60R18, while Carbon Edition, Grand Touring, Signature, and Touring Plus use 255/50R20. The difference is tied to wheel diameter, not a change from radial to another tire construction.
That means trim identification matters before replacement. Two CX-9 vehicles from the same model year can require different tires even though the overall tire height is very close, so the safest approach is to confirm the sub-model and inspect the actual wheel-and-tire combination currently installed on the vehicle.
Choosing the Right Tire
What should I consider when choosing a 255/50R20 tire for a 2023 Mazda Trucks CX-9?
Start by confirming that the vehicle is one of the 20-inch sub-models: Carbon Edition, Grand Touring, Signature, or Touring Plus. The correct size is 255/50R20 radial, so the key selection factors are staying with the proper size and choosing a tire suited to the vehicle’s real use, whether that is daily driving, highway travel, or mixed family-duty service.
Wheel condition, alignment, and suspension wear should also be part of the decision. On a newer crossover, uneven wear patterns or vibration can point to issues that should be addressed before mounting new tires, and any previous wheel change means clearance and fitment should be checked on the actual vehicle rather than assumed.
What should I consider when choosing a 255/60R18 tire for a 2023 Mazda Trucks CX-9?
The 255/60R18 size applies to the 2023 Mazda Trucks CX-9 Touring. Choosing within that size begins with confirming the 18-inch wheel setup, then comparing tires based on the kind of driving the vehicle sees most often, such as routine commuting, family trips, or longer highway use where ride quality and steady tracking matter.
A replacement tire should also be matched to the vehicle’s current condition. Checking tread wear across the old tires, inspecting for alignment issues, and confirming that the wheels are straight can prevent a new set from developing the same problems, especially on a crossover that may have seen curb contact or pothole impacts.
How do I choose between the available tire sizes for a 2023 Mazda Trucks CX-9?
The choice is not between two optional sizes for the same wheel. The 2023 Mazda Trucks CX-9 uses 255/60R18 on Touring and 255/50R20 on Carbon Edition, Grand Touring, Signature, and Touring Plus, so the correct tire depends on the wheel diameter and trim-specific setup already on the vehicle.
If the CX-9 still has its original wheels, trim identification usually resolves the question quickly. If wheels have been swapped, use the actual rim diameter and current vehicle clearance as the deciding factors, because two tires with similar overall height can still require very different wheels and should not be selected by appearance alone.
Restoration & Appearance
Does correct tire fitment matter for a 2023 Mazda Trucks CX-9 restoration or refurbishment?
Yes, correct tire fitment still matters even on a modern vehicle like the 2023 Mazda Trucks CX-9. A proper refurbishment should begin with the correct size for the actual sub-model and wheel setup, which means 255/60R18 for Touring or 255/50R20 for the covered 20-inch trims. Keeping the correct size helps preserve intended stance, wheel relationship, and everyday drivability.
Appearance is part of that equation, but visual similarity alone is not enough. A refurbishment-minded owner should confirm the tire size against the trim, verify the wheel diameter on the vehicle, and avoid assuming that another CX-9 setup is appropriate simply because the overall tire profile looks close at a glance.
How does tire size affect the appearance of a 2023 Mazda Trucks CX-9?
Tire size changes the visual balance between wheel and sidewall on the 2023 Mazda Trucks CX-9. The 255/50R20 setup presents more wheel and a shorter sidewall, while the 255/60R18 setup places more visual emphasis on the tire sidewall. Both maintain a very similar overall height, but they create a noticeably different look.
That matters when a vehicle is being refreshed to match its trim presentation. Choosing the correct size for the sub-model keeps the wheel-and-tire proportion aligned with the vehicle’s intended setup, while switching sizes without changing wheels is not an option and changing both should be checked carefully for clearance and overall fitment.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2023 Mazda Trucks CX-9?
Yes, modifications can affect tire fitment on a 2023 Mazda Trucks CX-9. Aftermarket wheels, suspension changes, altered ride height, or body modifications can change the clearance relationship around a 255/50R20 or 255/60R18 tire. Even when the tire size remains the same, wheel width and offset changes can alter how the tire sits in the wheel opening.
Any CX-9 that has been modified should be checked at full steering lock and through suspension travel before settling on a replacement. Tire choice should be based on the actual wheel-and-suspension setup on the vehicle, not only on the trim name, because small hardware changes can affect rubbing and clearance.
What should I inspect before driving a 2023 Mazda Trucks CX-9 on new tires?
Inspect the wheels, valve stems, lug hardware, and the condition of the existing suspension and steering components before regular driving on new tires. The new tires should match the correct CX-9 size for the sub-model, and the vehicle should not show signs of uneven tire wear, vibration, or obvious alignment problems that could shorten tire life quickly.
Tire pressure should be set correctly, and the first drives should include attention to tracking, steering feel, and any rubbing or vibration. A fresh set of tires can reveal issues that older worn tires were masking, so it is wise to recheck inflation, lug torque, and visible clearance after the initial miles.
How often should tires on a 2023 Mazda Trucks CX-9 be inspected?
Tires on a 2023 Mazda Trucks CX-9 should be inspected regularly rather than only at replacement time. A routine check should include tread depth, uneven wear, cuts, punctures, sidewall damage, and pressure condition on whichever size the vehicle uses, either 255/50R20 or 255/60R18. Frequent inspection is especially helpful on vehicles used for family travel or longer highway miles.
Monthly visual checks are a sensible habit, with closer inspection before a road trip or after impacts with potholes or curbs. Watching for shoulder wear, center wear, or repeated pressure loss can help catch alignment, inflation, or wheel issues early, before they affect ride quality or shorten the life of the new tires.
