About 175/50R18 Tires

The 175/50R18 is a relatively uncommon tire size found primarily on select compact and subcompact vehicles, including certain trims of the Honda Insight and some European city cars designed for fuel efficiency. This narrow profile combined with an 18-inch rim diameter is often chosen by manufacturers prioritizing low rolling resistance and improved aerodynamics. Owners should verify their specific vehicle's fitment requirements before purchasing, as this size has limited cross-compatibility with other models.

For budget-conscious buyers, Hankook and Toyo offer dependable options in this size at competitive price points without sacrificing basic safety and durability. Mid-range shoppers may consider Michelin's energy-efficient lines or Continental's EcoContact series, which balance performance and longevity well for this narrow, fuel-economy-oriented size. Premium buyers can look to Bridgestone or Pirelli for top-tier ride quality, tread life, and wet weather performance in this specialty fitment.

Treddur is currently tracking 10 listings for 175/50R18 tires. Prices range from $62.99 to $257.98 depending on brand and retailer.

Shopping for this size in late winter or early spring can yield better availability, as demand spikes in fall when drivers switch to winter tires on more common sizes, sometimes leaving this niche size easier to source. Purchasing early also ensures you are not caught waiting on special orders, which are common for less mainstream tire sizes.

Due to its niche fitment and lower production volume, the 175/50R18 typically commands slightly higher prices than more common sizes, with retail prices generally ranging from around $90 to $180 per tire depending on brand and performance tier.
