Pirelli developed a new tyre for British hillclimbing in 2019, giving Avon its first rival in the 21st century. (Avon responded by introducing its new Hillclimb GT Super Soft Compound tyre on 4 June 2020.) Several drivers made the switch, including that year's Champion Wallace Menzies. Driving a Gould GR59 with a 3.3-litre V8 engine derived from the Cosworth XD, Menzies made it mathematically impossible for anyone to catch him after Round 27 (of 34) at Gurston Down on 25 August 2019. He became only the second Scottish driver to win the title after Graeme Wight Jr.
