2018 Mazda Trucks covered a modern crossover range that emphasized sharp handling, efficient packaging, and a more athletic feel than many mainstream utility vehicles. In that model year, the CX-3, CX-5, and CX-9 each occupied a different place in the lineup, from subcompact to midsize family use. Tire choice across 2018 Mazda Trucks varies by model rather than carrying one shared size, with six distinct radial sizes spread across three vehicles and multiple rim diameters depending on which crossover you own. Before narrowing down a tire, the first step is confirming whether you have a CX-3, CX-5, or CX-9, then matching the correct size to the wheel already on the vehicle.
Which Tire Size Is Right for Your 2018 Mazda Trucks
2018 Mazda Trucks uses six tire sizes, and they vary by model rather than being shared across the full lineup. Because these sizes span several different rim diameters, the real decision starts with confirming the exact model and wheel size on your vehicle before comparing tire styles. Understanding that distinction first saves time and helps ensure you choose the right match.
Year(s): 2018|Fit(s): CX-3|Construction: Radial|Rim: 18-in rim
The 215/50R18 is a metric radial size with a 215 millimeter section width, a stated 50-series profile, and an 18-inch rim diameter. This size is specific to the CX-3 rather than universal across 2018 Mazda Trucks. As a radial fitment, it suits owners who want the handling response and road manners expected from a modern crossover tire format.
Year(s): 2018|Fit(s): CX-3|Construction: Radial|Rim: 16-in rim
The 215/60R16 is a metric radial size with a 215 millimeter section width, a stated 60-series profile, and a 16-inch rim diameter. This size is specific to the CX-3 and mounts on a smaller wheel than the model's 18-inch alternative. It is the right path for a CX-3 owner who needs the 16-inch fitment rather than the larger-wheel version.
Year(s): 2018|Fit(s): CX-5|Construction: Radial|Rim: 19-in rim
The 225/55R19 is a metric radial size with a 225 millimeter section width, a stated 55-series profile, and a 19-inch rim diameter. This size is specific to the CX-5 and does not interchange across the other 2018 Mazda Trucks models shown here. It is the correct direction for a CX-5 equipped with the larger factory-style wheel package.
Year(s): 2018|Fit(s): CX-5|Construction: Radial|Rim: 17 in
The 225/65R17 is a metric radial size with a 225 millimeter section width, a stated 65-series profile, and a 17-inch rim diameter. BFGoodrich offers this size with an RBL sidewall, an S speed rating with a 112 mph ceiling, and a load rating of 2,150 pounds at 65 psi. Because this version is an All-Terrain T/A KO2, it appeals to CX-5 owners who want a more rugged tread character in the correct 17-inch size.
Year(s): 2018|Fit(s): CX-9|Construction: Radial|Rim: 20-in rim
The 255/50R20 is a metric radial size with a 255 millimeter section width, a stated 50-series profile, and a 20-inch rim diameter. This size is specific to the CX-9 and corresponds to the largest wheel diameter used across 2018 Mazda Trucks here. It is the correct fitment path for a CX-9 already equipped with 20-inch wheels.
Year(s): 2018|Fit(s): CX-9|Construction: Radial|Rim: 18-in rim
The 255/60R18 is a metric radial size with a 255 millimeter section width, a stated 60-series profile, and an 18-inch rim diameter. This size is specific to the CX-9 rather than shared with the smaller Mazda crossover models. It is the size to confirm when your CX-9 uses the 18-inch wheel package instead of the 20-inch option.
Three models are covered for 2018 Mazda Trucks. Tire size varies by model, so identifying whether you have a CX-3, CX-5, or CX-9 matters before choosing a tire, and each model also carries its own wheel diameter choices. Select your model below to narrow your fitment history and tire options.
2018 Mazda Trucks CX-3
The 2018 Mazda Trucks CX-3 is the smallest member of the group, blending hatchback-like proportions with crossover ride height and Mazda's characteristically sporty tuning. Its tires mount on either 16-inch or 18-inch wheels, so wheel size confirmation is especially important before moving on to a specific tire choice.
The 2018 Mazda Trucks CX-5 sits in the heart of Mazda's crossover range and is known for combining family-vehicle practicality with a more refined driving feel than many compact SUVs. Its tires mount on either 17-inch or 19-inch wheels, and that distinction determines which size belongs on the vehicle.
The 2018 Mazda Trucks CX-9 is the largest model in this group, aimed at buyers who wanted three-row utility without giving up a more upscale design and road feel. Its tires mount on 18-inch or 20-inch wheels, making the existing wheel package the key detail to verify before selecting a size.
One product is available across six tire sizes for 2018 Mazda Trucks vehicles. The 225/65R17 size has one BFGoodrich radial option in an RBL sidewall style, so confirm that your CX-5 uses the 17-inch fitment before selecting.
These FAQs sort out which 2018 Mazda Trucks model uses which size, how modern metric radial sizing reads, and what to check for fitment, road use, and long-term care on lightly driven crossover vehicles.
Size Basics & Fitment
What tire sizes fit 2018 Mazda Trucks vehicles?
2018 Mazda Trucks vehicles use six tire sizes across three crossover models. The CX-3 uses 215/50R18 or 215/60R16, the CX-5 uses 225/55R19 or 225/65R17, and the CX-9 uses 255/50R20 or 255/60R18. These are all radial sizes, but they do not share one common rim diameter across the lineup. The only published rim-width range here is for 225/65R17, which fits 17-inch rims measuring 6.0 to 8.0 inches wide.
That means year and make alone are not enough to choose a tire for 2018 Mazda Trucks. You need to identify the exact model first, then confirm whether it is on the smaller or larger wheel package for that model. Checking the sidewall of the current tire and the wheel diameter before ordering is the fastest way to avoid choosing a correct-size tire for the wrong version of the vehicle.
What does 215/50R18 mean on a 2018 Mazda Trucks tire?
On a 2018 Mazda Trucks tire, 215/50R18 is a modern metric radial size. The 215 is the nominal section width in millimeters, 50 is the aspect ratio, meaning the sidewall height is 50 percent of the section width, R identifies radial construction, and 18 is the wheel diameter in inches. In this application, 215/50R18 belongs to the CX-3.
That code tells you far more than width alone. A CX-3 that uses 18-inch wheels needs the 18-inch tire size, and it cannot be replaced with the model's 16-inch alternative unless the wheel itself changes as well. Reading the full sidewall code keeps you from matching only the first number and accidentally buying a tire that will not mount to your existing wheels.
Do all 2018 Mazda Trucks models use the same tire size?
No, 2018 Mazda Trucks models do not use the same tire size. The CX-3, CX-5, and CX-9 each have their own pair of sizes, and each pair uses different rim diameters. The CX-3 uses 16-inch or 18-inch fitments, the CX-5 uses 17-inch or 19-inch fitments, and the CX-9 uses 18-inch or 20-inch fitments.
That separation matters because crossover tires can look similar at a glance while being completely different in width, profile, and wheel diameter. If you are starting with only a registration card or a year-and-make search, confirm the model badge and the size molded into the current tire before moving forward. For 2018 Mazda Trucks, model identification is the first fitment checkpoint, not a minor detail.
Buying the Right Tire
What brands make tires for 2018 Mazda Trucks vehicles?
BFGoodrich is represented here for 2018 Mazda Trucks through the 225/65R17 size used on the CX-5. That tire is the All-Terrain T/A KO2, a radial design with an RBL sidewall and a 107S service description. No brand overlap appears across the other sizes in this year-and-make group.
For a buyer, that means brand choice depends heavily on the exact size rather than the Mazda nameplate alone. A CX-5 owner on 17-inch wheels can weigh whether an all-terrain style matches the vehicle's use, while owners of the other sizes should begin by confirming size and wheel diameter before comparing product families. Choosing by model and wheel package first is more useful than choosing by brand reputation alone.
What sidewall styles are available for 2018 Mazda Trucks tires?
The sidewall style identified here for 2018 Mazda Trucks is RBL in the 225/65R17 BFGoodrich All-Terrain T/A KO2. RBL means raised black letters, which gives the tire a more assertive utility look than a plain blackwall. No alternate sidewall treatment appears across the other sizes in this group.
Sidewall appearance matters most when you want the tire's visual character to match the vehicle's personality. On a compact or midsize modern crossover, a raised-letter all-terrain tire can shift the look toward a more rugged style than a standard highway radial. If appearance is part of your decision, confirm both the size and the sidewall treatment on the exact product rather than assuming all tires in that size will look the same.
What is the difference between the BFGoodrich All-Terrain T/A KO2 and a standard road-focused tire for 2018 Mazda Trucks?
For 2018 Mazda Trucks, the BFGoodrich All-Terrain T/A KO2 shown in 225/65R17 is a radial tire built around a light-truck-oriented all-terrain concept. It carries a 107S service description, supports up to 2,150 pounds at 65 psi, fits 17-inch rims that are 6.0 to 8.0 inches wide, and weighs 39 pounds. That profile is more utility-minded than a typical crossover highway tire.
The practical difference is use case and appearance, not simple size alone. A CX-5 owner who wants a tougher tread character and raised black letters may find that style appealing, while an owner focused on stock-like road use may prefer to stay close to the kind of tire originally associated with crossover street driving. Matching the tire's character to how the vehicle is actually used is just as important as matching the dimensions.
Fitting & Setup
What rim width do 2018 Mazda Trucks tires require?
A confirmed rim-width range appears here for one 2018 Mazda Trucks size: 225/65R17 fits rims from 6.0 to 8.0 inches wide. That size belongs to the CX-5. The other 2018 Mazda Trucks sizes are identified by tire and rim diameter, but no additional rim-width ranges accompany them here.
Rim width matters because two tires with the same wheel diameter do not necessarily suit the same wheel width equally well. If you are working with a CX-5 on 17-inch wheels, the 6.0-to-8.0-inch range gives you a clear checkpoint before mounting. For the other sizes, verify the actual wheel specification on the vehicle or through Mazda service information before making any change from what is already fitted.
Do 2018 Mazda Trucks tires require inner tubes?
The 2018 Mazda Trucks sizes here are modern radial applications, and the available 225/65R17 product is presented as a standard radial size without a tube-type marking. Nothing in this group points toward an inner-tube requirement in the way vintage tube-type tires would. That places these fitments in the modern tubeless category unless a wheel-specific issue says otherwise.
Even so, the wheel itself still needs to be in proper condition for tubeless service. Check bead seats for corrosion or damage, inspect the valve stem, and make sure the wheel has not been bent or poorly repaired. On a late-model crossover such as 2018 Mazda Trucks, the wheel's sealing condition is the real setup concern, not the kind of tube-versus-no-tube decision common on much older vehicles.
Maintenance, Storage & Longevity
How should I store a 2018 Mazda Trucks when the tires are fitted?
A stored 2018 Mazda Trucks should be kept away from direct sunlight, standing moisture, and ozone sources such as electric motors, battery chargers, furnaces, or welders. Keep the tires inflated to the vehicle's normal storage pressure, park on a clean surface, and move the vehicle occasionally if it will sit for extended periods. Radial tires generally tolerate storage better than older bias-ply designs, but they still age from environment and time.
Good storage habits help preserve both the tread and the casing. If the vehicle will sit for months, washing road salts off the wheels and tires first is worthwhile, and using stands can help reduce prolonged static loading in some situations. The goal is simple: stable temperature, low ozone exposure, and periodic attention so the tires are still ready when the vehicle returns to regular use.
How long do tires on a 2018 Mazda Trucks typically last?
On a 2018 Mazda Trucks vehicle, tire life should be judged by age and condition as much as tread depth. A good rule is to evaluate collector or low-mileage tires closely once they reach about five to seven years old, and to treat around ten years as a serious replacement point regardless of miles. The DOT date code on the sidewall is the best way to confirm actual tire age.
That matters because many lightly driven crossovers appear to have plenty of tread left while the rubber has already aged out. Cracking, hardening, irregular wear, or repeated air loss can all arrive before the tread is gone. If your 2018 Mazda Trucks sees occasional seasonal use rather than constant commuting, age-based inspection is more reliable than mileage alone when deciding whether the tires are still serviceable.
How often should tires on a 2018 Mazda Trucks be inspected?
Tires on a 2018 Mazda Trucks should be inspected before every drive and more carefully before any longer trip. Look for sidewall cracking, punctures, bulges, uneven tread wear, and signs of impact damage, then confirm that all four tires are holding the intended pressure. A quick visual check catches many age- and road-related issues before they become a roadside problem.
A deeper inspection every few months is also smart, especially if the vehicle is parked outdoors or driven infrequently. Measure tread depth across the tire, inspect the inside sidewall if possible, and check the spare if the vehicle still carries one. Regular inspection is particularly useful on modern crossovers because tire condition can change long before the vehicle gives any obvious warning through noise or ride quality.
Restoration & Authenticity
What tires were originally fitted to the 2018 Mazda Trucks CX-3?
A 2018 Mazda Trucks CX-3 belongs to the modern era of factory radial fitment, and the two associated sizes here are 215/50R18 and 215/60R16. That means the original-style baseline is a metric radial on either 18-inch or 16-inch wheels, depending on the wheel package the vehicle carried. There is no reason to approach a 2018 CX-3 as a bias-ply or tube-type restoration case.
For authenticity, the key is matching the exact size and general tire character to the wheel package actually on the vehicle. Buyers preserving a stock presentation should confirm the original placard, owner's literature, or marque-specific resources if the vehicle has changed hands or had wheel swaps. On a modern Mazda crossover, correctness is mostly about size, wheel diameter, and overall visual appropriateness rather than vintage construction details.
Does correct tire fitment matter for showing a 2018 Mazda Trucks?
Correct tire fitment still matters when showing a 2018 Mazda Trucks, even though the vehicle is far newer than traditional concours classics. Judges and knowledgeable enthusiasts tend to notice whether the size matches the vehicle, whether the wheel diameter is appropriate, and whether the tire's overall look suits a stock or near-stock presentation. An aggressive all-terrain tread on a street-focused crossover can change that impression quickly.
The practical takeaway is to decide whether your goal is factory-style presentation or a personalized driver. If the vehicle is being judged, verify the original wheel and tire size combination before arrival and avoid assuming that any tire that physically mounts is visually correct. Event standards vary, so local marque groups or model-specific forums are often the best place to confirm how much deviation a particular show will tolerate.
What is the difference between stock-style fitment and the BFGoodrich All-Terrain T/A KO2 for the 2018 Mazda Trucks CX-5?
On the 2018 Mazda Trucks CX-5, the BFGoodrich All-Terrain T/A KO2 in 225/65R17 keeps the correct wheel diameter and basic size family for the 17-inch application, but it changes the visual and functional character of the vehicle. It uses a raised black letter sidewall, a more utility-oriented all-terrain design, and a 107S service description. That differs from the cleaner street-focused look many owners associate with stock crossover tires.
If your CX-5 is being kept close to factory appearance, tire styling may matter just as much as dimensions. A more rugged tread and raised lettering can be desirable on a personalized driver, but they can also move the vehicle away from a showroom-like presentation. For a show-minded owner, size accuracy comes first, and sidewall style is the next detail worth checking carefully.
Safety & Road Use
Are 2018 Mazda Trucks tires safe for highway driving?
2018 Mazda Trucks uses modern radial tire sizes, which are fundamentally well suited to highway use when the tires are in good condition and matched to the correct wheel. The published 225/65R17 BFGoodrich option carries an S speed rating, which corresponds to a 112 mph ceiling. In ordinary real-world driving, the condition, age, inflation, and load on the tire matter more than the theoretical top-speed number alone.
Highway safety comes down to using the correct size, maintaining proper pressure, and making sure the tires are not aged out or damaged. A crossover with fresh, properly inflated tires will usually be limited by weather, braking distance, cargo load, or driver caution long before it approaches the speed ceiling on the sidewall. Always treat the rating as a maximum capability under proper conditions, not a target speed.
What inflation pressure should I use for 2018 Mazda Trucks tires?
Inflation pressure for 2018 Mazda Trucks should follow the vehicle placard or owner's manual first, because factory pressure targets are specific to each model and wheel package. The 225/65R17 BFGoodrich All-Terrain T/A KO2 is rated to carry 2,150 pounds at 65 psi, but that is the tire's maximum load-pressure reference, not an across-the-board running recommendation for every 2018 Mazda Trucks application.
That distinction is important because a maximum sidewall pressure and a vehicle's operating pressure are not the same thing. Start with Mazda's recommended cold pressure for your exact model and tire size, then make sure the tire itself is appropriate for that use. If a vehicle has been modified, heavily loaded, or switched to a different tire type, verify the pressure strategy before relying on assumptions carried over from another size.
What should I check before taking a 2018 Mazda Trucks on a longer drive?
Before a longer drive in a 2018 Mazda Trucks, inspect each tire for cracking, cuts, punctures, bulges, and uneven wear, then set pressures cold and confirm the spare is serviceable if one is present. Make sure valve stems are sound, wheel nuts are secure, and no tire is rubbing because of prior wheel or suspension changes. A modern crossover still benefits from a thorough pre-trip walkaround, especially if it has been sitting.
Tires are only one part of the preparation, but they are the only part of the vehicle that touches the road. On a longer run, also check brakes, fluid levels, lights, and the overall load you plan to carry. If the vehicle has older tires with good-looking tread, give extra attention to age and sidewall condition, because those are often the deciding factors in whether a trip starts confidently or ends with preventable trouble.
