Hi-Q’s retail director, Chris Kisby began his Goodyear career working in the Carlisle territory alongside some of the original Jack Blacklock team. He said: “Jack has left behind quite a legacy. It was his hard work and determination to succeed that’s created the Hi-Q that exists today.
“He will be sadly missed by all those who knew him at Hi-Q and Goodyear Dunlop.” He leaves behind a daughter, son-in-law and grand-daughter.
