The 2016 Mazda Trucks CX-9 arrived as a modern three-row crossover with sharper styling and a more car-like road feel than many family SUVs in its class. Buyers looking at one today are usually balancing everyday drivability with the need to match the correct wheel and tire package for the exact trim. Tire fitment centers on two radial sizes, 255/50R20 and 255/60R18, and the right choice depends on the sub-model and its wheel diameter. That means the real decision is not bias-ply versus radial, but confirming whether the vehicle wears the 18-inch or 20-inch setup. Once that is settled, selection comes down to staying true to the intended fitment and checking wheel compatibility before replacement.
Which Tire Size Is Right for The 2016 Mazda Trucks CX-9
The 2016 Mazda Trucks CX-9 uses two primary tire sizes, and they are tied to specific sub-models and wheel diameters. Both fitments are radial, but the first step is confirming whether the vehicle has the 18-inch or 20-inch wheel package, since that determines which size belongs on it and narrows the replacement search quickly.
A 255/50R20 tire uses a 255-millimeter section width, a 50-series aspect ratio, radial construction, and a 20-inch rim. On the 2016 Mazda Trucks CX-9, this size belongs to sub-models equipped with the 20-inch wheel package, so it is the lower-profile of the two primary fitments. Its sizing keeps the tire in a modern metric format that is familiar to current replacement buyers. Choose this size only after confirming that the vehicle is one of the CX-9 trims built around the 20-inch wheel diameter rather than the 18-inch setup.
A 255/60R18 tire also uses a 255-millimeter section width, but with a 60-series aspect ratio and an 18-inch rim. For the 2016 Mazda Trucks CX-9, this size applies to sub-models fitted with the 18-inch wheel package, making wheel diameter the key fitment point. It stays within the same modern radial sizing system while pairing a taller sidewall profile with the smaller rim. This is the size to evaluate when the CX-9 carries the 18-inch factory-style wheel setup and not the 20-inch alternative.
Sub-model fitment matters on the 2016 Mazda Trucks CX-9 because tire size changes with the trim's wheel package. Grand Touring and Signature use one size, while Sport and Touring use another, so confirming the exact sub-model helps prevent an 18-inch and 20-inch mismatch.

2016 Mazda Trucks CX-9 Grand Touring
The 2016 Mazda Trucks CX-9 Grand Touring uses the 255/50R20 radial tire size. Tire selection for this trim starts with confirming the 20-inch wheel setup, then choosing a replacement that matches the intended fitment and maintains proper clearance.
The 2016 Mazda Trucks CX-9 Signature also uses the 255/50R20 radial tire size. That keeps the focus on the 20-inch wheel package, so replacement shopping should center on matching that diameter before comparing tire options.
The 2016 Mazda Trucks CX-9 Sport uses the 255/60R18 radial tire size. For this trim, the practical step is confirming the 18-inch wheel arrangement so the replacement tire matches the original fitment approach rather than the larger-wheel trims.
The 2016 Mazda Trucks CX-9 Touring uses the 255/60R18 radial tire size. That means replacement decisions should begin with the 18-inch wheel diameter, then move to overall fitment checks if the vehicle has had any wheel or suspension changes.
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.
Frequently Asked Questions
Common questions for the 2016 Mazda Trucks CX-9 usually center on the correct tire size by trim, whether the vehicle uses 18-inch or 20-inch wheels, and what to inspect before replacing tires on a used or modified example.
Tire Size & Fitment
What tire size fits a 2016 Mazda Trucks CX-9?
The 2016 Mazda Trucks CX-9 uses either 255/50R20 or 255/60R18, depending on the sub-model. Grand Touring and Signature use 255/50R20, while Sport and Touring use 255/60R18. Both are radial tire fitments, but they are tied to different wheel diameters.
The important step is matching the tire size to the trim and wheel package already on the vehicle. A CX-9 with 20-inch wheels needs the 255/50R20 fitment, and one with 18-inch wheels needs 255/60R18. If the vehicle has aftermarket wheels, confirm the actual rim diameter before choosing tires.
What size rim does a 2016 Mazda Trucks CX-9 use?
A 2016 Mazda Trucks CX-9 uses either an 18-inch or 20-inch rim, depending on sub-model. Sport and Touring are paired with the 255/60R18 size on an 18-inch rim, while Grand Touring and Signature use 255/50R20 on a 20-inch rim.
Rim diameter is the first thing to verify because the two tire sizes are not meant for the same wheel. Reading the sidewall can help, but checking the wheel itself is the safer approach, especially on a used CX-9 that may have had wheel changes during its life.
Do all 2016 Mazda Trucks CX-9 sub-models use the same tire size?
No, the 2016 Mazda Trucks CX-9 does not use one tire size across every sub-model. Grand Touring and Signature use 255/50R20, while Sport and Touring use 255/60R18. The difference follows the trim-specific wheel package rather than a change in tire construction.
That makes trim identification important before replacement. Two CX-9s from the same model year can need different tires simply because one carries 18-inch wheels and the other carries 20-inch wheels. Matching the tire to the actual wheel setup helps avoid mounting delays and prevent fitment mistakes.
Choosing the Right Tire
What should I consider when choosing a tire for a 2016 Mazda Trucks CX-9?
Start with the correct primary size for the exact trim: 255/50R20 for Grand Touring and Signature, or 255/60R18 for Sport and Touring. Both are radial fitments, so the main selection issue is not construction type but matching the tire to the proper wheel diameter and intended vehicle setup.
After confirming size, check the wheel dimensions actually on the vehicle, especially if it was purchased used. A CX-9 with aftermarket wheels, suspension changes, or non-original tire sizing may need closer review of clearance and overall fit. Staying with the correct size is usually the cleanest path for predictable replacement.
How do I choose between the available 255/50R20 and 255/60R18 tires for a 2016 Mazda Trucks CX-9?
The choice between 255/50R20 and 255/60R18 is not a matter of preference on a stock 2016 Mazda Trucks CX-9. Each size belongs to a different trim and wheel diameter, so the correct tire is determined by whether the vehicle uses the 20-inch or 18-inch setup.
A buyer should confirm the trim and then verify the actual wheel diameter on the vehicle before ordering replacement tires. That matters most on a CX-9 that may have received wheel swaps after leaving the factory. Once the correct size is confirmed, comparison can focus on tread style and service priorities.
What tire series are available for the 2016 Mazda Trucks CX-9?
The 2016 Mazda Trucks CX-9 page centers on fitment, with 255/50R20 and 255/60R18 as the primary tire sizes tied to the vehicle's trim and wheel package. The most important series-level decision starts only after the correct size and wheel diameter have been confirmed.
Series names matter when comparing replacement tires, but they should always come second to exact fitment. A CX-9 owner should first identify whether the vehicle is built around the 18-inch or 20-inch setup, then compare the available tire options within that correct size rather than mixing the two fitments.
Restoration & Appearance
Does correct tire fitment matter for a 2016 Mazda Trucks CX-9 restoration?
Yes, correct tire fitment still matters on a 2016 Mazda Trucks CX-9, even though it is a newer vehicle than most traditional restorations. Matching the proper 255/50R20 or 255/60R18 size to the correct trim helps preserve the intended stance, wheel relationship, and overall presentation.
Appearance can change quickly when a CX-9 wears the wrong profile or the wrong rim diameter for its trim level. Owners aiming for an authentic factory-style look should confirm the original wheel setup on the vehicle first, then choose replacement tires that stay faithful to that trim-specific fitment.
How does tire size affect the appearance of a 2016 Mazda Trucks CX-9?
Tire size has a visible effect on the 2016 Mazda Trucks CX-9 because the two primary fitments are built around different wheel diameters. Grand Touring and Signature use 255/50R20, while Sport and Touring use 255/60R18, so the visual balance between sidewall and wheel changes with the trim.
That means appearance-minded owners should avoid assuming one size looks right on every CX-9. A vehicle designed around 20-inch wheels presents differently than one built around 18-inch wheels. Confirming the original trim and wheel package is the simplest way to keep the overall look aligned with the vehicle's intended setup.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2016 Mazda Trucks CX-9?
Yes, modifications can affect tire fitment on a 2016 Mazda Trucks CX-9. Wheel changes, suspension lowering, altered offsets, or other aftermarket parts can change the clearance relationship around a 255/50R20 or 255/60R18 tire, even when the replacement size itself is correct for the original trim.
That is why a modified CX-9 should be checked at the wheel wells and steering range before new tires go into service. Tire selection gets simpler when the vehicle remains in stock form, but any change in wheel diameter, width, or ride height makes a hands-on clearance check worth doing.
What should I inspect before driving a 2016 Mazda Trucks CX-9 on new tires?
Before driving a 2016 Mazda Trucks CX-9 on new tires, inspect the wheel diameter, confirm the tire size matches the trim, and look over the condition of the wheels themselves. It is also smart to check inflation pressure, valve stems, and the basic condition of brakes and suspension components nearby.
A short road test should follow installation so any rubbing, pull, or vibration can be caught early. Used vehicles deserve extra attention because prior owners may have changed wheels or suspension parts. Starting with a careful inspection helps the correct 255/50R20 or 255/60R18 fitment perform as intended.
How often should tires on a 2016 Mazda Trucks CX-9 be inspected?
Tires on a 2016 Mazda Trucks CX-9 should be inspected regularly, not only when replacement time arrives. A quick visual check for uneven wear, cracking, cuts, bulges, or air loss is worthwhile throughout the year, and a closer inspection makes sense before longer trips or seasonal changes.
Routine inspection matters even more on a vehicle that sees mixed city and highway use or has spent time parked. The right 255/50R20 or 255/60R18 size still needs sound condition to perform properly. Keeping an eye on pressure and wear patterns can also reveal alignment or suspension issues before they become larger problems.
