About 175/40R20 Tires

The 175/40R20 is an uncommon and highly specialized tire size not typically found on mainstream passenger vehicles. It may be used on certain custom builds, low-profile concept vehicles, or modified cars where a very narrow tread width combined with a large 20-inch wheel diameter is desired. Buyers should verify fitment carefully, as this size has limited OEM applications.

At the budget level, options are extremely limited for this size, but some lesser-known specialty manufacturers may offer compatible fitments worth exploring. Mid-range buyers might consider brands like Nankang or similar performance-oriented manufacturers that occasionally produce uncommon sizes. Premium shoppers should consult directly with brands like Michelin or Continental, as custom or special-order options may be available through authorized dealers.

Treddur is currently tracking 5 listings for 175/40R20 tires. Prices range from $55.06 to $244.08 depending on brand and retailer.

Because this is a niche tire size with limited availability, buyers should purchase as soon as they find stock rather than waiting for seasonal sales. Inventory can be scarce year-round, making timing less relevant than simply securing the tires when they are available.

Due to the rarity of the 175/40R20 size, prices tend to be higher than comparable mainstream sizes, and significant discounting is uncommon given the low production volumes and limited market competition.
