Introduced as Mazda’s three-row crossover for families who still wanted responsive road manners, the 2007 Mazda Trucks CX-9 sits at the point where utility and car-like driving feel began to merge in a more polished way. Its stance and trim level make tire selection more configuration-specific than broad crossover fitment usually suggests. The 2007 Mazda Trucks CX-9 uses radial tires, with 245/60R18 on Sport and Touring models and 245/50R20 on the Grand Touring. That means the real choice starts with identifying the exact trim and wheel diameter. From there, the focus shifts to maintaining the intended proportions, preserving clearance, and matching the tire to everyday road use.
Which Tire Size Is Right for The 2007 Mazda Trucks CX-9
Two tire sizes apply to the 2007 Mazda Trucks CX-9, and the correct one depends on the sub-model and wheel diameter. Sport and Touring models use 245/60R18, while the Grand Touring uses 245/50R20, so the first step is confirming the trim and whether the vehicle still has its intended 18-inch or 20-inch wheels before comparing tire options.
A 245/50R20 tire uses a 245-millimeter section width, a 50-series aspect ratio, radial construction, and fits a 20-inch rim. On the 2007 Mazda Trucks CX-9, this size belongs to the Grand Touring and reflects a lower-profile metric radial fitment than the 18-inch setup used on other trims. Its shorter sidewall changes the selection priorities toward maintaining the intended wheel-and-tire proportion and confirming clearance with the actual wheel installed. This is the size to evaluate when the vehicle retains its 20-inch Grand Touring wheel package or an equivalent wheel setup with the same key dimensions.
A 245/60R18 tire has a 245-millimeter section width, a 60-series aspect ratio, radial construction, and mounts on an 18-inch rim. On the 2007 Mazda Trucks CX-9, this size is used on Sport and Touring models and represents the taller-sidewall of the two primary fitments. That makes wheel diameter confirmation especially important, since a 20-inch tire choice is not interchangeable with this 18-inch application. This size is the correct starting point for buyers keeping the original 18-inch wheel format or verifying fitment on a CX-9 that may have changed hands with different wheels.
Sub-model fitment matters on the 2007 Mazda Trucks CX-9 because tire size changes with trim. Sport and Touring share one radial size, while Grand Touring uses a different size on a different rim diameter, so identifying the exact sub-model helps prevent a wheel-and-tire mismatch.

2007 Mazda Trucks CX-9 Grand Touring
The 2007 Mazda Trucks CX-9 Grand Touring uses the 245/50R20 radial tire size. Tire selection here starts with confirming the 20-inch wheel package, then choosing a replacement that preserves the intended overall proportions and suits normal road use.
The 2007 Mazda Trucks CX-9 Sport uses the 245/60R18 radial tire size. That makes the 18-inch wheel diameter the key fitment checkpoint before comparing replacement tires, especially on vehicles that may have been fitted with aftermarket wheels.
The 2007 Mazda Trucks CX-9 Touring also uses the 245/60R18 radial tire size. Because it shares fitment with the Sport, the main task is confirming that the vehicle still carries the correct 18-inch wheel setup before choosing a tire.
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)

Frequently Asked Questions
For a 2007 Mazda Trucks CX-9, the main questions center on trim-specific tire size, 18-inch versus 20-inch rim fitment, and what to inspect before putting a crossover of this age back into regular road use.
Tire Size & Fitment
What tire size fits a 2007 Mazda Trucks CX-9?
The 2007 Mazda Trucks CX-9 uses two tire sizes depending on trim. Sport and Touring models use 245/60R18 radial tires, while the Grand Touring uses 245/50R20 radial tires. Both are modern metric radial sizes, but they fit different wheel diameters.
The most important step is confirming which sub-model you have and whether the vehicle still has the intended wheel package. A CX-9 that has been fitted with aftermarket wheels or replacement rims may no longer match its original trim-based fitment, so checking the current wheel diameter before selecting tires helps avoid an expensive mismatch.
What size rim does a 2007 Mazda Trucks CX-9 use?
A 2007 Mazda Trucks CX-9 uses either an 18-inch or 20-inch rim, depending on sub-model. Sport and Touring models use 18-inch rims with 245/60R18 tires, while the Grand Touring uses 20-inch rims with 245/50R20 tires.
Rim diameter should be verified before anything else because an 18-inch tire cannot be mounted on a 20-inch wheel, and the reverse is also true. Looking at the tire sidewall and measuring the actual wheel setup is especially worthwhile on used vehicles, since trim badges and current wheels do not always reflect the original configuration.
Do all 2007 Mazda Trucks CX-9 sub-models use the same tire size?
No, the 2007 Mazda Trucks CX-9 does not use one tire size across every sub-model. The Sport and Touring share 245/60R18 radial tires, while the Grand Touring uses a different radial size, 245/50R20.
That difference means trim identification matters before comparing tires. It also means the wheel diameter has to match the tire size you choose, since these fitments are tied to different rim sizes. Buyers looking at a CX-9 with replaced wheels should confirm the actual wheel-and-tire combination on the vehicle rather than relying only on the model name.
Choosing the Right Tire
What should I consider when choosing a 245/60R18 tire for a 2007 Mazda Trucks CX-9?
A 245/60R18 tire for a 2007 Mazda Trucks CX-9 should first match the Sport or Touring trim and the vehicle’s actual 18-inch wheel diameter. After that, the key considerations are maintaining the correct size, using a radial tire in the proper format, and choosing a tire suited to the way the vehicle is driven.
It helps to confirm that the wheels are original-size and that no suspension or wheel changes have altered clearance. Comparing overall tire dimensions within the correct size range, checking load suitability, and inspecting the condition of the wheels can make a bigger difference than chasing appearance alone on a crossover intended for regular road use.
What should I consider when choosing a 245/50R20 tire for a 2007 Mazda Trucks CX-9?
A 245/50R20 tire is the trim-specific fitment for the 2007 Mazda Trucks CX-9 Grand Touring. The main priorities are confirming the 20-inch wheel setup, keeping the correct metric radial size, and selecting a tire that preserves the intended proportions of the Grand Touring package.
Because this size uses a lower-profile sidewall than the 18-inch fitment, wheel condition and actual clearance deserve close attention. Checking for bent rims, uneven wear, and any rubbing at full steering lock is worthwhile, especially if the vehicle has seen replacement wheels or suspension changes during its life.
How do I choose between the available tire sizes for a 2007 Mazda Trucks CX-9?
Choosing between the two tire sizes for a 2007 Mazda Trucks CX-9 is not a matter of preference alone. The correct size is determined by sub-model and wheel diameter: 245/60R18 for Sport and Touring, and 245/50R20 for Grand Touring.
Once the trim and wheel diameter are confirmed, the decision becomes much simpler because you are no longer comparing unlike fitments. From there, focus on the correct size format, the condition and width of the wheels already on the vehicle, and whether the CX-9 is being maintained for everyday road use or occasional family-hauler duty.
Restoration & Appearance
Which tire should I choose for a period-style 2007 Mazda Trucks CX-9?
For a period-style 2007 Mazda Trucks CX-9, the best starting point is the original trim-based size format rather than trying to substitute a different wheel diameter. That means 245/60R18 for Sport or Touring models and 245/50R20 for a Grand Touring, both in radial construction.
Keeping the correct size preserves the crossover’s intended stance more effectively than forcing a different package onto the vehicle. Owners pursuing a more authentic early-CX-9 presentation should also pay attention to wheel style and overall ride height, since those details influence appearance just as much as the sidewall dimensions do.
Does correct tire fitment matter for a 2007 Mazda Trucks CX-9 restoration?
Yes, correct tire fitment matters on a 2007 Mazda Trucks CX-9 restoration because the two factory-style size paths are tied to different trims and different wheel diameters. Using the wrong tire size can alter the vehicle’s appearance and create unnecessary fitment questions even before the CX-9 goes back on the road.
A restoration-minded owner should confirm the sub-model, the wheel diameter actually on the vehicle, and whether any prior owner changed the wheels or suspension. Even on a newer collector-era vehicle, the right tire size helps the finished vehicle look settled and coherent rather than mismatched.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2007 Mazda Trucks CX-9?
Yes, modifications can affect tire fitment on a 2007 Mazda Trucks CX-9. Aftermarket wheels, altered offsets, suspension changes, lowering, or worn suspension components can all change how a 245/60R18 or 245/50R20 tire sits in the wheel opening and how much clearance is available in use.
That matters most when the vehicle no longer carries its original trim-based wheel package. Steering-lock clearance, fender clearance, and wheel width should all be checked on the actual vehicle before committing to replacement tires. Even a correct nominal tire size can become a problem if the wheel setup has been changed significantly.
What should I inspect before driving a 2007 Mazda Trucks CX-9 on new tires?
Before driving a 2007 Mazda Trucks CX-9 on new tires, inspect the wheels for bends or damage, confirm the wheel diameter matches the tire size, and look over the suspension and steering components for looseness or wear. Tire pressure should also be set correctly and rechecked after the first miles of use.
A short road test should include listening for rubbing, vibration, or pulling, especially on a vehicle with unknown service history. It is also smart to verify alignment condition and make sure older brake or suspension issues are not mistaken for tire problems once the CX-9 returns to regular road use.
How often should tires on a 2007 Mazda Trucks CX-9 be inspected?
Tires on a 2007 Mazda Trucks CX-9 should be inspected regularly, not just when tread appears low. A monthly visual check is a sensible routine, with closer attention before longer trips and after any impact with potholes, curbs, or road debris.
Inspection should include tread wear, sidewall cracking, bulges, cuts, and signs of slow air loss. On an older CX-9 that may sit for periods, checking tire age and watching for flat-spotting or weather-related deterioration is just as important as tread depth. Consistent inspections help catch small issues before they affect ride quality or fitment confidence.
