The 155/75R21 is a relatively uncommon tire size that appears on select European compact and subcompact vehicles, as well as certain specialized urban electric vehicles designed for narrow urban environments. Some models from manufacturers like Citroën and related PSA Group vehicles have used this narrow profile size. It may also be found on certain lightweight utility vehicles and small trailers in some markets.
At the budget end, Hankook and Sailun offer affordable options in this size that provide reliable everyday performance without a high price tag. Mid-range shoppers should consider Michelin's entry-level lines or Continental's value-oriented offerings, which balance longevity and comfort at a reasonable cost. For premium performance, Michelin and Bridgestone remain top choices, delivering superior wet-weather handling and extended tread life that can offset the higher upfront investment.
Like most tire sizes, prices for 155/75R21 tires tend to dip slightly during spring and fall seasonal changeover periods when retailers offer promotions. Because this is a less common size, availability can be limited, so purchasing in advance rather than waiting for peak season discounts is often the more practical strategy.
Due to its specialized and low-demand nature, the 155/75R21 size tends to carry a premium over more common tire sizes, with limited retailer competition keeping prices relatively stable and discounts less frequent.
