How we ranked these tires for the mazda CX-9
We started with the latest model-year's OEM tire size; 255/50R20; and filtered our catalog of 22,000+ tires to those offered in that exact size. From there, four parallel rankings:
- Best all-season ranks on a weighted score: tire type matches passenger car segment, season is "all-season", premium brand bonus (Michelin / Continental / Bridgestone / Pirelli / Goodyear / Nokian).
- Best budget ranks on cost-per-warranty-mile; the lower the better. Premium brands get no bonus here.
- Best quiet ranks on the EU tire-label dB rating; lower is quieter.
- Best winter filters to tires marked 3PMSF severe-snow rated or all-weather class, with a small premium-brand bonus because winter-compound R&D is capital-intensive.
For sedans and compacts, the all-season touring tire below is the best default; long warranty, low cabin noise, reasonable cost per mile. Switch to the quiet pick if highway droning is a deal-breaker; switch to the winter pick if you see significant snow each year. Use the side-by-side comparison above to weigh the trade-offs against your specific driving; highway-heavy, winter-state, performance-oriented, or budget-constrained.

Verbatim excerpts from complaints filed with NHTSA about Mazda CX-9. Reports are published by NHTSA as filed and are lightly cleaned here only to remove intake codes.
October 2021 purchase 2 Cooper Evolution H/T All-Season 245/60R18. With less than 8k miles, both tires developed deformities/bulging on upper sidewal/tread,line intersect, causing vehicle to shimmy. The dot #'s of both tires are up83 1LE 1021. Tires have a 60k warranty. Cooper tires issues two safety recalls due to sidewall deformities on this tire model, same plant, but in a different sizes. February 26, 2021 cooper tires has issued yet another safety recall on this exact model tire but in a different size. The 2 cooper evolution HT tires seem to also have sidewall defects. I feel that the bulging tires are a safety hazard due to manufacturing defects. I would like to have my 245/60r18 cooper evolution as well as all of the other sizes of this model tire made by cooper, futher reviewed to the recall list
All 4 of my BH255/50R20 XL 109v NOKIAN WR G4 vehicle tires are exhibiting abnormal tread degradation and excessive sidewall cracking. The tire defect includes a circumferential crack along the top of all 4 tires, where the top of the tire's sidewall and tread base meet. Upon tire inspection, the structural integrity and safety of these tires with continued usage is questionable. The tires in question are only 26 months old and have approximately 31K miles of usage.
