About 155/40R18 Tires

The 155/40R18 is a relatively uncommon and specialized tire size that is not typically found on standard passenger vehicles. It is most often associated with certain low-speed electric vehicles, neighborhood electric vehicles (NEVs), and some specialty or concept cars with narrow, low-profile designs. Buyers should verify fitment carefully, as this size has limited OEM applications.

At the budget level, options are extremely limited due to the niche nature of this size, but lesser-known Asian manufacturers such as Hankook or Kenda may occasionally offer compatible fitments. Mid-range shoppers should look to Continental or Yokohama if availability permits, as these brands sometimes produce specialized narrow low-profile sizes. For premium applications, Michelin or Bridgestone would be the top choices if they produce this size, though buyers should confirm availability directly with retailers before expecting consistent stock.

Treddur is currently tracking 7 listings for 155/40R18 tires. Prices range from $75.06 to $314.78 depending on brand and retailer.

Because this is a niche tire size with limited availability, buyers should purchase whenever stock is available rather than waiting for seasonal sales, as selection may be sparse year-round. Checking online retailers is often the most reliable approach, as local shops rarely stock this size.

Due to its niche status and low production volumes, the 155/40R18 tends to command higher per-tire prices than comparably sized common fitments, with limited discounting and frequent out-of-stock situations.
