The 175/55R20 is a relatively uncommon tire size that is most notably used on the Toyota Prius C (Aqua in some markets) and certain Fiat 500 models, where its narrow width and large diameter help maximize fuel efficiency. This size is specifically engineered for compact, fuel-conscious vehicles where aerodynamics and low rolling resistance are prioritized over sportier handling characteristics.
At the budget tier, options are extremely limited due to the size's rarity, but Toyo and occasional Hankook offerings may appear at lower price points. For mid-range buyers, Bridgestone Ecopia and Michelin Energy Saver lines sometimes offer this size, balancing fuel efficiency with reliable treadwear. Premium shoppers should look to Michelin as the most consistent provider of high-quality tires in this fitment, particularly those optimized for the low rolling resistance demands of hybrid vehicles.
Treddur is currently tracking 26 listings for 175/55R20 tires. Prices range from $67.93 to $566.99 depending on brand and retailer.
Shopping for 175/55R20 tires in late winter or early fall can yield better availability, as this niche size has limited stock at most retailers and waiting until peak season may result in longer lead times or backorders. Purchasing ahead of seasonal transitions is strongly recommended given the constrained supply chain for this uncommon fitment.
Due to its niche application and limited production volume, the 175/55R20 typically commands a price premium over more common tire sizes, with few discount options available and prices remaining relatively stable year-round due to constrained market competition.
