About 185/40R18 Tires

The 185/40R18 is a relatively uncommon and specialized tire size that is occasionally found on small performance-oriented vehicles and some compact cars with larger-diameter wheel setups. It may be used on certain tuner builds and modified economy cars where owners have opted for larger 18-inch wheels with a low-profile sidewall. Due to its niche nature, availability is limited compared to more mainstream tire sizes.

At the budget level, brands like Nankang and Accelera occasionally produce this size and offer an affordable entry point for cost-conscious buyers. Mid-range options may include Falken or Hankook if they carry this size in their performance lineup, providing a balance of quality and value. For premium performance, Michelin or Continental would be ideal if available, though shoppers may need to special-order this size from those manufacturers.

Treddur is currently tracking 1 listing for 185/40R18 tires. Prices range from $73.81 to $73.81 depending on brand and retailer.

Because this is a low-volume specialty size, shoppers should buy early rather than waiting for seasonal sales, as stock can be scarce year-round. Waiting for end-of-season discounts may result in finding no available inventory at all.

Due to low demand and limited production runs, the 185/40R18 tends to carry a price premium over more common sizes, and significant discounting is rare.
