About 165/30R21 Tires

The 165/30R21 is an uncommon and highly specialized tire size not typically found on mainstream passenger vehicles. It may appear on certain custom builds, low-profile concept cars, or specialty vehicles with uniquely configured wheel and suspension setups. Buyers should verify fitment carefully, as this size has very limited OEM applications.

Due to the extremely limited demand for this size, budget-tier options are virtually nonexistent from major manufacturers, making sourcing from specialty or custom tire suppliers the most practical approach. Mid-range buyers may find options through niche European brands or custom tire importers who cater to low-volume specialty sizes. Premium buyers should consult directly with manufacturers like Michelin or Continental about custom or semi-custom production runs, though costs will be significantly higher than standard sizes.

Treddur is currently tracking 1 listing for 165/30R21 tires. Prices range from $339.99 to $339.99 depending on brand and retailer.

Because this is a niche size with limited availability, buyers should purchase whenever stock is found rather than waiting for seasonal sales, as inventory can be sparse year-round. Waiting for end-of-season discounts may result in missed availability altogether.

Prices for the 165/30R21 size tend to be unpredictably high and variable due to extremely low production volumes and limited market competition, often commanding a premium well above comparably sized conventional tires.
