The 185/35R21 is a relatively uncommon and highly specialized tire size primarily found on certain European luxury and performance vehicles with low-profile, wide-rim fitments. Some custom-configured Audi, BMW, and Mercedes-Benz models may use this size as part of a staggered or aftermarket wheel setup. Due to its niche dimensions, availability is limited and it is rarely found as a standard OEM fitment on mass-market vehicles.
At the budget end, Nankang and Achilles offer options in uncommon sizes like this one at accessible price points, though longevity and performance may vary. Mid-range shoppers should consider Falken or Toyo, which provide a solid balance of performance and durability for low-profile specialty fitments. For premium buyers, Michelin and Continental are the top choices, offering superior handling precision, ride quality, and treadwear for this demanding tire profile.
Treddur is currently tracking 10 listings for 185/35R21 tires. Prices range from $58.08 to $75.99 depending on brand and retailer.
Because this is a low-volume specialty size, seasonal sales events like Black Friday or end-of-year clearances are among the best times to purchase, as retailers rarely discount this size outside of promotional periods. Buying in late winter or early spring may also yield better availability before summer performance driving season increases demand.
Due to its niche status and low production volume, the 185/35R21 typically commands higher-than-average prices relative to more common sizes, with limited discounting and occasional supply constraints that can push costs upward.
