About 305/80R21 Tires

The 305/80R21 is a specialty tire size most commonly found on heavy-duty military vehicles, large off-road trucks, and custom-built expedition rigs. This size is also used on certain agricultural and commercial utility vehicles where high ground clearance and load capacity are essential. Its fitment is relatively niche compared to mainstream consumer sizes.

For budget-conscious buyers, Advance Tyre and similar specialty off-road brands occasionally offer options in this size at lower price points. Mid-range buyers may consider Michelin XZL or similar military-spec tires, which offer reliable performance and reasonable availability. At the premium end, brands like Goodyear and Continental produce high-load military and expedition-grade tires in this size built for extreme durability and performance.

Because this is a specialty size with limited retail availability, buyers should purchase well in advance of need rather than waiting for seasonal sales, as stock can be inconsistent year-round. Pricing is unlikely to fluctuate significantly with seasonal demand given the low volume of this size in the market.

Tires in the 305/80R21 size typically carry a significant price premium due to their specialty nature, low production volume, and the heavy-duty load ratings required, with prices generally ranging from several hundred to over a thousand dollars per tire.
