The Grandtrek AT23 from Dunlop is built to provide confident all-season driving performance for owners of sport utility vehicles and larger crossovers. The AT23 has been used in most cases as original equipment on various Lexus and Toyota models over the past few years, as well as being available for vehicles that require different 18 inch fitments. An all-season tread compound is M+S rated for increased performance in year-round driving conditions. As with most any tyre made today, dry traction is very good. The tyre’s continuous center rib increases steering response and stability throughout the speed range.
