About 155/30R21 Tires

The 155/30R21 is an uncommon and highly specialized tire size not typically found on standard passenger vehicles. It may appear on certain custom builds, low-profile concept vehicles, or specialty automotive applications. Buyers should verify fitment carefully, as this size has very limited OEM applications.

At the budget level, options are extremely limited due to the uncommon nature of this size, and buyers may need to consider lesser-known specialty manufacturers. Mid-range shoppers might explore Nankang or similar brands that produce a wider range of uncommon sizes. For premium needs, contacting specialty tire dealers directly is recommended, as brands like Michelin or Continental may offer custom or low-volume production tires for niche fitments.

Treddur is currently tracking 2 listings for 155/30R21 tires. Prices range from $171.86 to $315.00 depending on brand and retailer.

Because this is a niche size with limited availability, buyers should purchase as soon as they find stock rather than waiting for seasonal sales. Inventory can be scarce year-round, making timing less of a factor than simply locating a supplier.

Due to extremely low demand and limited production, prices for the 155/30R21 size tend to be higher per unit than comparably sized common tires, and availability fluctuations can cause significant price variability.
