Mazda has developed factory recommended scheduled maintenance services that support all major vehicle systems. Mazda recommends dealers follow the scheduled maintenance tables as cited in the vehicle-specific workshop manual or owner's manual. Services performed outside of Mazda's factory scheduled maintenance are not recommended. These services are unnecessary and create unneeded expenses for your customers.

Is there a fix? Manufacturer service bulletins
The manufacturer has issued service bulletins covering tires on this vehicle — documented repair instructions, service campaigns, or warranty extensions sent to dealers. A TSB isn't a recall (it's not a free safety remedy), but it's the manufacturer acknowledging the issue and how to fix it.
New CARB regulation regarding mandatory checking and documenting of tire pressure whenever a vehicle is in for service work. This applies to all service shops (including Mazda dealerships) in California effective September 1, 2010.

The failure pattern owners describe
Owners of 2007 Mazda CX-7s report severe and premature tire wear across multiple tire brands, with tread depth becoming unsafe well before typical replacement intervals. Most common complaint pattern: tires wearing to 4/32" or less tread depth between 12,000 and 25,000 miles. Several owners found tires bald except for circumferential grooves at 18,800 miles or requiring replacement at 16,000 miles. One owner reported a blowout on the rear passenger side at just 3,000 miles on Bridgestone Turanza EL42 tires after a low-pressure warning.
Specific wear patterns noted include cupping (uneven wear on inside of tires at 12,800 miles) and outer edge wear suggesting underinflation. One Prinx HiCountry HT2 tire developed a structural failure with a steel belt wire protruding through the tread at the shoulder, causing repeated air loss with no visible puncture.
Owners consistently report the vehicle's 4,000-pound weight exceeds tire load rating. Dealers and manufacturers (Mazda, Bridgestone, Firestone, Goodyear) redirect blame between each other—vehicle alignment and owner driving habits are ruled out where investigated. Some owners received partial reimbursement; others received none. Mazda service departments provided conflicting tread measurements. No manufacturer issued recalls or warrantied replacements.
Failure modes owners describe
Premature tread wear across all four tires
Excessive and abnormal wear occurring at low mileage intervals, with tires reaching unsafe tread depths (4/32" or less) far sooner than expected for new-vehicle OEM tires.
When: 12,000 to 25,480 miles reported; multiple instances at 16,000-18,800 miles
Symptoms owners cite: Severe tread loss leaving tires bald except for circumferential grooves; Rapid wear to critical tread depth of 4/32" or less; All four tires affected equally or with front-to-rear variation; Increasing difficulty maneuvering vehicle at low speed due to lack of traction
Repairs/costs cited: Owners purchased replacement tires ranging $160 (used take-offs) to $750 per set. One owner replaced all four Bridgestone Turanza tires at 18,800 miles.
Recalls/TSBs owners mention: Bridgestone dealers advised no tread-wear warranty exists. Mazda and tire manufacturers denied warranty claims, each blaming the other. One Mazda service location offered 50% reimbursement for one customer at 20,000 miles; another offered to split cost of front-tire replacement only.
Severe tire cupping and uneven wear patterns
Cupping (scalloped indentations) on tire tread, indicating suspension or alignment issues, combined with outer edge wear suggesting underinflation despite proper tire pressure.
When: 12,800 miles
Symptoms owners cite: Severe steering wheel vibration; Uneven wear on inside of all four tires (cupping); Outer tread wear pattern consistent with underinflation; Wear more pronounced on front or rear
Repairs/costs cited: Independent tire shop (NTB) diagnosed severe tire cupping. Goodyear Eagle RS-A P235/55R18 tires replaced.
Recalls/TSBs owners mention: Mazda offered partial cost-sharing: one customer received 50% reimbursement at 20,000 miles; another was offered Mazda purchase of one front tire only, with customer responsible for second front tire and both rear tires.
Structural tire failure with internal belt defect
Steel belt wire protruding through tire tread from an internal manufacturing defect, causing repeated air loss without puncture or external damage.
When: Shortly after installation
Symptoms owners cite: Repeated loss of tire pressure with no visible puncture; Steel belt wire visible protruding through tread near shoulder area; No warning lights prior to pressure loss; Internal defect, not caused by road hazard
Repairs/costs cited: Prinx HiCountry HT2 tire (size 235/60R18) deemed non-repairable per safety guidelines due to structural failure.
Tire blowout at very low mileage
Sudden tire failure resulting in blowout while driving on freeway shortly after vehicle purchase and low-pressure warning indication.
When: 3,000 miles
Symptoms owners cite: Low tire pressure warning light illuminated; Blowout on rear passenger side tire while on freeway; Bridgestone Turanza EL42 tire failure
Repairs/costs cited: Tire failure occurred 5 minutes after entering freeway.

How serious is the tires problem on the 2007 Mazda CX-7?
It's a documented issue but not catastrophic. 14 complaints have been filed. Repairs average $150 and most owners catch it before it causes a breakdown.
At what mileage does the tires typically fail?
Across the 10 complaints that reported odometer mileage, most tires failures cluster between 12,355 and 17,000 miles, with the median around 16,000. A quarter of owners report trouble before 12,355; a quarter make it past 17,000. Maintenance history matters more than the odometer alone — this is the reported failure window, not a guarantee.
What does it cost to fix?
Independent shops typically charge around $150 for tires repairs on this vehicle. Dealer pricing tends to run 20-40% higher. The exact figure depends on the specific failure mode, parts availability, and your local labor rates. If you're outside factory warranty, an extended service contract often covers this category.
Are there any recalls related to tires?
No active recalls currently cover tires issues on this vehicle. The complaints filed represent owner-reported failures that haven't risen to the level of a manufacturer-issued recall — but they're still worth knowing about before you buy or budget for repairs.
