A Combination of Roads for 30,000 Easy Going miles

Worst tyre I have had in over 50 years of motoring. After 2 years and 14,000 miles first sign of cracking in grooves between treads. Cracking progressively got worse until had to change tyres at 4 years and 30,000. By this time tyres were in a distressed state with multiply cracks in groves and chunking of tread. Material looked very hard and brittle. For reference previous set of Pirelli tyres were changed after 5 years and 43,000 miles with over 2mm tread left,
