About 175/45R21 Tires

The 175/45R21 is a relatively uncommon and specialized tire size that is most notably used on the Renault Zoe electric vehicle, particularly European market variants. This narrow, tall-profile tire is designed to optimize rolling efficiency and range for electric and fuel-efficient compact cars. Buyers should verify fitment carefully, as this size has limited crossover use across other vehicle makes and models.

For budget-conscious buyers, Radar and Nankang occasionally offer tires in this uncommon size at lower price points, though availability may be limited. Mid-range shoppers should look at Continental and Hankook, which produce variants suited to the efficiency demands of electric vehicles in this size. For premium performance, Michelin is the most recognized choice in this fitment, offering their Energy-series tires optimized specifically for range and low rolling resistance on EVs.

Treddur is currently tracking 9 listings for 175/45R21 tires. Prices range from $57.27 to $176.60 depending on brand and retailer.

Because this size is primarily associated with electric vehicles sold in European markets, availability can be inconsistent year-round, so purchasing outside of peak winter and summer changeover seasons may yield better stock and pricing. Buying in late spring or early fall often provides the most options before seasonal demand spikes reduce inventory.

Due to the niche nature of this tire size and its limited production volume, prices tend to run higher than comparably sized more common fitments, with less frequent discounting and promotional pricing observed throughout the year.
