Infiniti Q60S Tires — Fitment by Year

The 2014–2015 Infiniti Q60S is a sport-trimmed variant of the Q60 coupe, sharing the same rear-wheel-drive platform and performance-oriented suspension tuning as the broader Q60 lineup. As a luxury sport coupe, the Q60S is built around confident handling, refined road manners, and a driving experience that places real demands on the tires beneath it. Choosing the right replacement tires means balancing grip and responsiveness with the ride comfort expectations that define the Infiniti brand.

Tire sizing on the 2014–2015 Q60S can vary depending on the specific trim and whether the vehicle is equipped with staggered fitment — meaning different tire widths on the front and rear axles. Staggered setups are common on sport-tuned rear-wheel-drive coupes and affect which tires are interchangeable side to side. Before purchasing, confirm your exact front and rear sizes from your door jamb sticker or owner's manual, as selecting the wrong size can affect speedometer accuracy, clearance, and handling balance.

For a vehicle in this category, ultra-high-performance (UHP) all-season and summer tires are the most common replacements. Summer tires offer the sharpest dry and wet grip and are well-suited to drivers who prioritize handling feel, but they are not designed for use in near-freezing or snowy conditions. All-season UHP tires trade a small amount of peak grip for year-round usability and are a practical choice in climates that see mild winter weather. If you live in a region with genuine winter conditions, a dedicated set of winter tires on a separate wheel set is the most effective solution — all-season tires are not a substitute for winter-rated rubber in ice or heavy snow.

Load rating and speed rating matter on a performance-oriented coupe. The Q60S carries a higher-output engine and a chassis tuned for spirited driving, so confirm that any replacement tire meets or exceeds the speed rating specified in your owner's manual. Dropping to a lower speed rating than factory-specified is not recommended. Load index should also be verified against the factory placard — this is especially relevant if you are considering a wider aftermarket tire size.

Sidewall profile is another consideration. The Q60S typically runs a relatively low-profile tire, which contributes to its crisp steering response but also means the sidewall absorbs less road shock than a taller tire. If you find the ride too firm, some owners move to a slightly taller sidewall within a compatible overall diameter — but any such change should be calculated carefully to avoid rubbing or speedometer deviation. When in doubt, verify fitment compatibility for your specific year, trim, and wheel size before ordering.
