The 195/30R21 is a relatively uncommon and specialized tire size primarily found on certain custom-built vehicles, lowered show cars, and some European compact models with aftermarket or unique OEM wheel fitments. Its narrow width combined with a very low profile and large 21-inch rim diameter makes it a niche fitment seen on select tuner builds and modified vehicles. Buyers should verify fitment carefully, as this size is not widely used across mainstream passenger vehicles.
At the budget end, Nankang and Thunderer offer options in specialty sizes like this at accessible price points, though availability may be limited. Mid-range shoppers can consider Toyo or Falken, which provide a balance of performance and durability for low-profile fitments. For premium performance, Continental and Michelin represent top-tier quality if fitments are available in this size, offering superior handling and longevity.
Treddur is currently tracking 9 listings for 195/30R21 tires. Prices range from $364.00 to $728.00 depending on brand and retailer.
Because this is a low-volume specialty size, stock levels can be limited year-round, so purchasing early in the spring or fall season change periods is advisable to avoid supply shortages. Waiting for end-of-season sales may result in limited availability due to the niche nature of this tire size.
Due to its niche and low-demand nature, the 195/30R21 tends to command relatively higher per-unit prices compared to common sizes, with limited discount opportunities given the narrow selection of manufacturers that produce it.
