The 275/75R21 is a relatively uncommon tire size primarily found on select full-size pickup trucks and heavy-duty SUVs, particularly certain configurations of the Ford F-150 and Ram 1500 with upgraded wheel packages. Some aftermarket lifted truck builds also use this size when paired with 21-inch wheels seeking a balance between a tall sidewall and modern wheel aesthetics. Owners of these vehicles often prioritize all-terrain or highway-terrain performance given the trucks' typical use cases.
At the budget end, Ironman and Westlake offer entry-level options in this size at lower price points, though availability may be limited. Mid-range shoppers should consider General Tire or Falken, which provide solid tread life and performance at a reasonable cost. For premium performance, Michelin, BFGoodrich, and Goodyear are reliable choices offering superior tread wear warranties, ride quality, and all-terrain capability for this size.
Prices on this size tend to dip slightly in late winter and early spring as retailers clear inventory ahead of summer tire season, making February through April a good window to buy. If you need all-season or all-terrain tires, purchasing outside of peak fall demand can also yield modest savings.
Due to its relatively niche fitment, the 275/75R21 typically commands higher prices than more common truck tire sizes, with limited supply keeping discounts less frequent compared to mainstream sizes.
