The 2018 Mazda Trucks CX-5 sits in the compact crossover class, where everyday comfort, tidy road manners, and practical utility all matter as much as appearance. For owners, tire selection is less about vintage-style construction and more about matching the exact trim and wheel package on the vehicle. This CX-5 uses radial tires in two primary sizes, 225/55R19 and 225/65R17, depending on sub-model. That makes trim identification and wheel-diameter confirmation the first step before comparing available options. Once size is confirmed, the real decision becomes choosing a tire that suits the vehicle's current setup, intended road use, and overall stance.
Which Tire Size Is Right for The 2018 Mazda Trucks CX-5
Two tire sizes apply to the 2018 Mazda Trucks CX-5, and they are tied to different sub-models and different wheel diameters. Both are radial fitments, but the first thing to confirm is the exact trim and whether the vehicle is on 17-inch or 19-inch wheels before choosing a replacement tire.
225/55R19 is a metric radial size in which 225 identifies the nominal section width in millimeters, 55 is the aspect ratio, R indicates radial construction, and 19 is the wheel diameter in inches. On the 2018 Mazda Trucks CX-5, this size belongs to trims equipped with 19-inch wheels, so wheel confirmation matters before moving ahead. Its lower-profile format gives this fitment a different visual proportion than the 17-inch alternative. This is the size to evaluate when the vehicle already carries the larger factory-style wheel package and the goal is to stay with that wheel diameter.
225/65R17 is a metric radial size where 225 is the nominal width in millimeters, 65 is the aspect ratio, R marks radial construction, and 17 identifies the wheel diameter in inches. On the 2018 Mazda Trucks CX-5, this size is used on trims with 17-inch wheels, making wheel diameter the key fitment checkpoint. Available product choice in this size includes a BFGoodrich All Terrain T/A KO2 with an RBL sidewall treatment. This size is the one to focus on when the CX-5 remains on 17-inch wheels or when replacement needs to match that existing wheel setup.
Sub-model fitment varies on the 2018 Mazda Trucks CX-5, so tire selection starts with identifying the exact trim. The difference is not just the tire size code, but also the wheel diameter the vehicle uses.

The 2018 Mazda Trucks CX-5 Grand Touring uses the 225/55R19 radial tire size. That means replacement tire selection begins with confirming the 19-inch wheel setup and then choosing a tire that matches the vehicle's intended road use and present wheel configuration.
The 2018 Mazda Trucks CX-5 Sport uses the 225/65R17 radial tire size. This trim should be matched to a 17-inch fitment, and that makes it especially important to verify that the vehicle still has its original wheel diameter if wheels have ever been changed.
The 2018 Mazda Trucks CX-5 Touring uses the 225/55R19 radial tire size. For this trim, the buying decision centers on maintaining the 19-inch fitment and checking that the current wheels and any suspension changes still suit that size.

Tire Size & Fitment
What tire size fits a 2018 Mazda Trucks CX-5?
The 2018 Mazda Trucks CX-5 uses two tire sizes: 225/55R19 and 225/65R17. Both are radial sizes, but they do not apply across every trim. Grand Touring and Touring use 225/55R19, while Sport uses 225/65R17.
The practical decision starts with confirming the exact sub-model and the wheel diameter currently on the vehicle. A CX-5 with aftermarket wheels or a previous wheel swap may no longer match its original trim-based setup, so the tire size should be matched to the wheels actually installed on the vehicle.
What size rim does a 2018 Mazda Trucks CX-5 use?
The 2018 Mazda Trucks CX-5 uses either a 17-inch or 19-inch rim, depending on sub-model. The 225/65R17 tire size corresponds to a 17-inch wheel, while the 225/55R19 tire size corresponds to a 19-inch wheel.
Wheel diameter should be confirmed before ordering replacement tires because the two CX-5 fitments are not interchangeable without changing wheels. It is also wise to check wheel width and inspect the stampings on the wheel itself if there is any doubt about whether the vehicle still has its original rim setup.
Why does the 2018 Mazda Trucks CX-5 have more than one tire size?
More than one tire size appears on the 2018 Mazda Trucks CX-5 because different sub-models use different wheel packages. Sport uses a 17-inch fitment with 225/65R17, while Grand Touring and Touring use a 19-inch fitment with 225/55R19.
That means the correct replacement tire is tied to trim and wheel diameter, not simply to year, make, and model alone. Before choosing a tire, check the sub-model, confirm the current wheel size, and make sure the vehicle has not been altered with different wheels that change the original fitment pattern.
Choosing the Right Tire
What should I consider when choosing a 225/65R17 tire for a 2018 Mazda Trucks CX-5?
Start with the correct size, radial construction, and wheel compatibility. For the 2018 Mazda Trucks CX-5 Sport, 225/65R17 is the applicable size, and available product details in this fitment include a BFGoodrich All Terrain T/A KO2 with a 6.0- to 8.0-inch rim-width range, RBL sidewall, and 2,150 lbs @ 65 psi maximum load capacity.
The next step is deciding whether the tire's character matches how the CX-5 is actually used. A buyer should compare wheel width, load needs, sidewall appearance, and whether the vehicle spends most of its time on pavement or sees rougher service, then verify that the current wheel and suspension setup suit the chosen tire.
What sidewall styles are available for 2018 Mazda Trucks CX-5 tires?
Among the available products for the 2018 Mazda Trucks CX-5, the visible sidewall style present is RBL in the 225/65R17 fitment. Sidewall treatment affects appearance more than size fitment, but it still matters to owners who want the tire's look to suit the vehicle's overall presentation.
A sidewall choice should always come after confirming the correct tire size and wheel diameter for the trim. Once that is settled, the sidewall style becomes part of the final selection, especially if the CX-5 has a more rugged, utility-oriented look or if the owner wants a cleaner, more understated appearance.
What brands offer tires for the 2018 Mazda Trucks CX-5?
BFGoodrich is represented among the available tire choices for the 2018 Mazda Trucks CX-5, specifically in the 225/65R17 fitment. That option appears in the All Terrain T/A KO2 series and gives owners of the 17-inch setup a clearly defined product to compare against their current tire needs.
Brand should be considered alongside the tire's size, intended use, and wheel requirements rather than as a stand-alone decision. For this CX-5, the more important questions are whether the vehicle uses the 17-inch or 19-inch setup and whether the chosen tire's construction, rim-width compatibility, and overall character match the way it is driven.
Restoration & Appearance
How does tire fitment affect the appearance of a 2018 Mazda Trucks CX-5?
Tire fitment has a noticeable effect on how a 2018 Mazda Trucks CX-5 sits and looks because the two approved sizes pair with different wheel diameters. A 225/55R19 on a 19-inch wheel presents a different visual balance than a 225/65R17 on a 17-inch wheel, even though both belong to the same model line.
Appearance decisions should still begin with the correct trim-based fitment rather than style alone. Keeping the proper wheel diameter and tire size for the sub-model helps preserve the intended proportions, while any move to different wheels or altered suspension should be checked carefully for clearance, stance, and overall compatibility.
Does correct tire fitment matter for a 2018 Mazda Trucks CX-5 restoration or refresh?
Correct tire fitment matters on a 2018 Mazda Trucks CX-5 because the vehicle uses trim-specific sizes tied to 17-inch or 19-inch wheels. Even on a modern vehicle, using the proper size helps preserve the intended look, wheel-to-tire proportion, and general character of the sub-model being refreshed.
Owners aiming for a clean, original-style presentation should confirm the trim, wheel diameter, and current wheel setup before replacing tires. If exact appearance details matter, it is worth checking vehicle-specific reference material or marque sources so the finished result reflects the right visual package rather than simply any tire that mounts.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2018 Mazda Trucks CX-5?
Yes, modifications can affect tire fitment on a 2018 Mazda Trucks CX-5. Wheel changes, altered offset, suspension lowering, lift changes, or body modifications can all change how a 225/55R19 or 225/65R17 tire sits within the wheelwell and how much room remains during steering and suspension travel.
Any CX-5 that has been modified should be checked for wheel diameter, wheel width, tire clearance, and rubbing at full lock before a replacement tire is chosen. Even when the size code matches an original trim fitment, the actual vehicle setup may call for closer inspection to avoid clearance problems on the road.
What should I inspect before driving a 2018 Mazda Trucks CX-5 on new tires?
Before driving a 2018 Mazda Trucks CX-5 on new tires, inspect wheel diameter, wheel condition, valve stems, lug torque, and tire pressure. It is also smart to confirm that the tires match the vehicle's actual trim-based fitment, whether that is 225/55R19 or 225/65R17.
A short road test should be followed by another visual check for rubbing, uneven seating, or signs of air loss. Owners should also look over suspension and steering components if the vehicle has high mileage, since worn parts can affect how a new set of tires behaves even when the size is correct.
How often should tires on a 2018 Mazda Trucks CX-5 be inspected?
Tires on a 2018 Mazda Trucks CX-5 should be inspected regularly, not just when tread looks low. Routine checks for pressure loss, uneven wear, cuts, bulges, and sidewall damage help catch problems early, especially on a vehicle that may see daily use, seasonal driving, or occasional rough-road service.
A visual inspection every month and a closer look before longer trips is a sensible habit. It also helps to inspect after pothole impacts or wheel changes, since the CX-5 uses two different wheel diameters across its trims and any mismatch or damage can affect ride quality, wear pattern, and overall road confidence.
