Toyo’s new full slick competition tyre, the Proxes RS1, was launched in the UK in time for the 2015 season. Its two 15” sizes (195/570R15 and 205/580R15) were joined by the larger 235/620R17, and now Toyo has added two 18” fitments to the range, 245/640R18 and 285/680R18. Toyo states that the tyre is its model for a large and growing market for specialist slick tyres, primarily amongst those that regularly attend track days or participate in club-level motorsport.
