In 2015, Mazda leaned hard into car-like crossover utility, and the CX-5 and CX-9 represented two distinct takes on that formula. The CX-5 emphasized nimble, efficient everyday driving, while the larger CX-9 served buyers who needed more cabin room and a broader road presence. Across 2015 Mazda Trucks models, tire sizing varies by model rather than carrying over across the full range, with four radial sizes split between the two nameplates and multiple rim diameters involved. The first step is confirming whether you have a CX-5 or CX-9, then matching the exact size already specified for that model before narrowing down product style and intended use.
Which Tire Size Is Right for Your 2015 Mazda Trucks
Four tire sizes are used across 2015 Mazda Trucks vehicles, and they vary by model rather than being shared across the full range. Because those sizes span four different rim diameters, the real decision starts with confirming the correct model and wheel diameter first, then choosing the product that suits how the vehicle is driven. Understanding that distinction before choosing a tire saves time and helps ensure the right match.
Year(s): 2015|Fit(s): CX-5|Construction: Radial|Rim: 19-in rim
225/55R19 is a metric radial size with a 225 millimeter section width, a stated 55-series profile, and fitment for a 19-inch wheel. This size is specific to the CX-5 rather than universal across 2015 Mazda Trucks models. It suits CX-5 owners who need to stay with the 19-inch wheel package already on the vehicle.
Year(s): 2015|Fit(s): CX-5|Construction: Radial|Rim: 17 in
225/65R17 is a metric radial size with a 225 millimeter section width, a stated 65-series profile, and fitment for a 17-inch wheel. BFGoodrich offers this size with an RBL sidewall, and the available example carries an S speed rating with a 112 mph ceiling and a 2,150 lb load capacity at 65 psi. This size is specific to the CX-5, and it fits owners who want to keep the factory-style 17-inch wheel diameter while choosing a more utility-oriented tread character.
Year(s): 2015|Fit(s): CX-9|Construction: Radial|Rim: 20-in rim
245/50R20 is a metric radial size with a 245 millimeter section width, a stated 50-series profile, and fitment for a 20-inch wheel. This size is specific to the CX-9 rather than shared across the 2015 Mazda Trucks range. It is the size to follow when the vehicle already wears the CX-9's 20-inch wheel setup.
Year(s): 2015|Fit(s): CX-9|Construction: Radial|Rim: 18-in rim
245/60R18 is a metric radial size with a 245 millimeter section width, a stated 60-series profile, and fitment for an 18-inch wheel. This size is specific to the CX-9 and does not cross over to the CX-5. It makes sense for owners who need to match the 18-inch wheel package on their CX-9 before comparing tread design and brand preference.
Two 2015 Mazda Trucks models are covered here: the CX-5 and CX-9. They do not share the same tire sizes, so identifying the model matters before choosing anything further. Select a model below to narrow fitment history and see the tires associated with that specific vehicle.
2015 Mazda Trucks CX-5
The 2015 Mazda Trucks CX-5 was Mazda's compact crossover, known for combining practical utility with a more responsive, car-like feel than many rivals in the segment. Its tires mount on either 17-inch or 19-inch wheels depending on the vehicle's wheel package, so the exact size on the vehicle should be confirmed before moving forward.
The 2015 Mazda Trucks CX-9 filled the larger three-row crossover role, with more overall size and a more substantial road presence than the CX-5. Its tires mount on either 18-inch or 20-inch wheels, and that wheel diameter is the key detail to verify before comparing tire options.
One product is available across four tire sizes for 2015 Mazda Trucks vehicles. The 225/65R17 size has one BFGoodrich radial option with an RBL sidewall. Confirm your exact size first, since the CX-5 and CX-9 do not share tire fitments.
These FAQs cover how 2015 Mazda Trucks tire sizes split between the CX-5 and CX-9, what the metric size codes mean, how rim diameter affects fitment, and what to check for long-term use on a modern crossover that may still see occasional collector-style storage.
Size Basics & Fitment
What tire sizes fit 2015 Mazda Trucks vehicles?
2015 Mazda Trucks vehicles use four tire sizes across two models. The CX-5 uses 225/55R19 or 225/65R17, while the CX-9 uses 245/50R20 or 245/60R18. All four are radial sizes, but they do not share a common rim diameter. The 225/65R17 size fits a 17-inch wheel and has a rim width range of 6.0 to 8.0 inches in the available BFGoodrich application.
That means year and make alone are not enough to choose a tire for 2015 Mazda Trucks. Start by identifying whether you have a CX-5 or CX-9, then confirm the wheel diameter already on the vehicle. If the vehicle has replacement wheels, check the sidewall of the current tire and the wheel itself before selecting a product.
What does 225/65R17 mean on a 2015 Mazda Trucks tire?
On a 2015 Mazda Trucks tire, 225/65R17 is a metric radial size. The 225 is the nominal section width in millimeters, 65 is the aspect ratio, R means radial construction, and 17 is the wheel diameter in inches. On the CX-5, this size appears with an S speed rating in the available BFGoodrich example, which carries a 112 mph ceiling.
That code matters because every part of it affects fitment and behavior. A 225/65R17 tire is not interchangeable with the CX-5's 225/55R19 size or with either CX-9 size unless the wheel diameter matches and the vehicle is set up for that package. Matching the full sidewall code is the safest starting point before comparing tread design or brand.
Do all 2015 Mazda Trucks models use the same tire size?
No, 2015 Mazda Trucks models do not use the same tire size. The CX-5 uses either 225/55R19 or 225/65R17, while the CX-9 uses either 245/50R20 or 245/60R18. Each size is model-specific, and the two models also differ in wheel diameter options, so there is no single tire size that covers the full year and make range.
That split is important if you are shopping by year and make alone or buying for a recently purchased vehicle. The CX-5 and CX-9 occupy different size classes, so their tire requirements reflect that. Confirming the exact model and wheel diameter first prevents ordering a tire that is correct for another 2015 Mazda crossover but wrong for your own.
Buying the Right Tire
What sidewall styles are available for 2015 Mazda Trucks tires?
2015 Mazda Trucks tire applications shown here are all radial, and the 225/65R17 size is available with an RBL sidewall from BFGoodrich. RBL means raised black letters, a style often chosen when an owner wants a more rugged or utility-focused appearance than a plain black sidewall. The other 2015 Mazda Trucks sizes are still selected first by exact fitment, then by the sidewall treatment offered in the product chosen for that size.
Sidewall style matters most when appearance is part of the decision, especially on a crossover that may be used for light trail duty or styled with a more aggressive look. If originality is not the goal, sidewall choice becomes a visual preference. Just be sure the tire's full size, load capability, and intended use still match the vehicle before focusing on lettering or cosmetic details.
What brands make tires for 2015 Mazda Trucks vehicles?
BFGoodrich makes a tire for the 2015 Mazda Trucks 225/65R17 application, specifically the All-Terrain T/A KO2 in radial construction. That product uses an RBL sidewall and carries a 107S service description. Brand availability can differ by size, so the CX-5 and CX-9 should be approached by exact tire code rather than assuming the same brand options carry across the whole model range.
For a buyer, that means brand selection follows fitment, not the other way around. If your CX-5 uses 17-inch wheels, BFGoodrich is a relevant option to compare. If you have a different size on a CX-5 or a CX-9, confirm that exact size first and then compare the brands that exist in that specific application.
What is the difference between the BFGoodrich All-Terrain T/A KO2 and a typical highway-style tire for the 2015 Mazda Trucks CX-5?
The BFGoodrich All-Terrain T/A KO2 offered in 225/65R17 for the 2015 Mazda Trucks CX-5 is a radial tire with an RBL sidewall, a 107S service description, a 2,150 lb load capacity at 65 psi, and a rim width range of 6.0 to 8.0 inches. Those details point toward a more utility-minded tire character than a conventional street-biased crossover tire, even though the size itself still has to match the CX-5 exactly.
That distinction matters if your CX-5 sees gravel roads, rougher surfaces, or you simply want a tougher visual profile. A highway-style tire in the same size would usually emphasize a quieter, more road-focused feel, while the KO2 leans toward all-terrain use. The right choice depends on how the vehicle is actually driven, not just on appearance.
Fitting & Setup
What rim width do 2015 Mazda Trucks tires require?
Rim width information for 2015 Mazda Trucks is available here for the 225/65R17 size used on the CX-5. That application works with a wheel width range of 6.0 to 8.0 inches on a 17-inch rim. The other 2015 Mazda Trucks sizes still need their correct wheel diameters matched first: 19 inches for 225/55R19, 20 inches for 245/50R20, and 18 inches for 245/60R18.
Rim width matters because the right diameter alone does not guarantee the wheel is appropriate for the tire. If your CX-5 has aftermarket wheels, verify both width and diameter before moving ahead. On any 2015 Mazda Trucks vehicle, treat the wheel and tire as a matched package rather than assuming one tire size can be stretched across multiple wheel setups.
Do 2015 Mazda Trucks tires require inner tubes?
The 2015 Mazda Trucks applications here are radial metric sizes, and the 225/65R17 BFGoodrich example does not carry a tube-type marking. That points to a tubeless-style modern fitment rather than the inner-tube arrangements associated with older collector tires. Because modern crossovers rely on matching the tire to the proper wheel, the wheel condition and valve stem condition matter just as much as the tire itself.
If your 2015 Mazda Trucks vehicle still uses its original late-model wheels, tube installation is generally not the first issue to solve. Instead, inspect the bead seats, valve stems, and any corrosion or impact damage on the wheel. If the vehicle has unusual replacement wheels or a specialty setup, confirm compatibility directly with the wheel and tire specifications before mounting.
Maintenance, Storage & Longevity
How should I store a 2015 Mazda Trucks when the tires are fitted?
A 2015 Mazda Trucks vehicle should be stored on a clean, dry surface away from direct sunlight, electric motors, welders, furnaces, and other ozone-producing equipment that can age rubber prematurely. Keep the tires inflated to the appropriate pressure for storage and move the vehicle periodically if it will sit for long stretches. Even radial tires can develop temporary flat-spotting when parked in one position for too long.
If the vehicle is laid up for a season, a cool enclosed garage is better than outdoor cover storage. Owners who store a CX-5 or CX-9 for long periods often benefit from occasional rolling, careful pressure checks, and keeping petroleum products off the sidewalls. Good storage habits protect both the tire casing and the wheel finish.
How long do tires on a 2015 Mazda Trucks typically last?
On a 2015 Mazda Trucks vehicle, tire age is usually as important as tread depth. A sensible collector and occasional-use rule is to begin evaluating tires closely once they reach about five to seven years of age, and to consider replacement around the 10-year mark regardless of mileage. The DOT date code on the sidewall is the reference point for that timeline.
That guideline matters because many CX-5 and CX-9 vehicles see mixed use, with some driven daily and others spending long periods parked. Low mileage does not stop rubber from aging. Cracking, hardening, vibration, or repeated pressure loss can all justify replacement sooner, especially if the vehicle is expected to make longer highway trips.
How often should tires on a 2015 Mazda Trucks be inspected?
Tires on a 2015 Mazda Trucks vehicle should be checked before every drive, and more thoroughly before any extended highway trip. Look for sidewall cracking, punctures, uneven wear, bulges, embedded debris, and pressure loss. Because these are modern radial applications, irregular wear can also point to alignment, suspension, or wheel-balance issues rather than a tire problem alone.
A quick walk-around catches problems before they become roadside failures. On a crossover like the CX-5 or CX-9, tire condition affects braking feel, wet-weather stability, and ride quality as much as outright safety. Add the spare to the inspection routine as well, since a neglected spare often goes flat or ages out long before it is needed.
Safety & Road Use
Are 2015 Mazda Trucks tires safe for highway driving?
2015 Mazda Trucks tire applications here are all radial, which is the construction expected for modern crossover highway use. The available 225/65R17 BFGoodrich example carries an S speed rating, which means a 112 mph ceiling under proper conditions. On a CX-5 or CX-9 in sound mechanical condition, the tire's rated capability is only one part of the picture; braking, suspension health, wheel condition, and inflation all matter just as much.
For normal interstate travel, the more practical concern is choosing the exact correct size and keeping the tires in good condition. A wrong-size tire, an overloaded vehicle, or neglected pressure maintenance will create trouble well before the speed rating becomes the limiting factor. Highway safety starts with fitment accuracy, condition, and realistic use.
What inflation pressure should I use for 2015 Mazda Trucks tires?
Inflation pressure on 2015 Mazda Trucks tires should follow the vehicle placard or owner's manual first, because factory pressure recommendations are tied to the vehicle's weight distribution and intended handling balance. The available 225/65R17 BFGoodrich application carries a maximum load of 2,150 lbs at 65 psi, but that figure is not a blanket running pressure recommendation for every CX-5 or every driving condition.
Use the manufacturer's rated maximum as a limit, not as a default setting. If your 2015 Mazda Trucks vehicle uses one of the other sizes, do not transfer the 65 psi figure across to them. Matching pressure to the exact tire size, load, and vehicle placard helps preserve handling, ride quality, and tread wear.
What should I check before taking a 2015 Mazda Trucks on a longer drive?
Before a longer drive in a 2015 Mazda Trucks vehicle, inspect each tire for cuts, bulges, cracking, punctures, irregular wear, and proper cold inflation pressure. Confirm that the sidewall size matches the vehicle's wheel package, and make sure the spare is usable as well. On a modern crossover, it is also smart to look at brake condition, alignment behavior, and whether the vehicle tracks straight under normal driving.
That pre-drive routine is especially useful if the vehicle has been parked for a while or recently changed hands. A quick inspection can catch an old tire, a mismatched size, or a slow leak before it becomes a highway problem. If anything looks questionable, sort it out before the trip rather than treating the drive as the test.
