About 155/45R18 Tires

The 155/45R18 tire size is a narrow, low-profile fitment most commonly found on small electric vehicles and eco-focused city cars, such as certain configurations of the Renault Twizy and some European microcars. This unusual size is also used on some lightweight concept and specialty vehicles where minimal rolling resistance and a compact footprint are priorities. Availability is more limited compared to mainstream sizes due to the specialized nature of the vehicles that require it.

At the budget end, Sailun and Nankang occasionally offer options in specialty narrow sizes like this at lower price points for cost-conscious buyers. Mid-range shoppers may find reliable performance from Continental or Hankook, both of which produce quality tires for compact and electric vehicle applications. For premium buyers, Michelin's energy-efficient tire lines offer superior longevity and low rolling resistance, making them a strong investment for electric microcar owners.

Treddur is currently tracking 14 listings for 155/45R18 tires. Prices range from $75.08 to $206.06 depending on brand and retailer.

Because this size is primarily used on urban and electric microvehicles rather than traditional passenger cars, demand fluctuates less with the seasons than standard sizes. However, purchasing in late winter or early spring can still yield modest savings as retailers clear inventory.

Due to its niche application and limited production volume, the 155/45R18 size tends to carry a price premium over more common sizes, with fewer competitive options available to drive prices down.
