The Nokian WR G4 is a true all-weather tire with performance in heat, rain, snow and sleet. An Aramid-reinforced sidewall adds durability, and an asymmetric tread supports responsive handling in wet or dry weather.
A dense sipe network with angled grooves gives grip in snow and slush. Low rolling resistance suits EVs and hybrids, and the Three Peak Mountain Snowflake mark covers moderate to severe winter use.
This 255/55R18 size carries a 109V load and speed rating with extra load (XL) construction. It has 11/32-inch tread depth, a 51 psi maximum inflation pressure, a UTQG rating of 540AA and an overall diameter of about 29 inches. It is backed by a 60,000-mile treadwear warranty.
