Thanks James,
Wow you have volvo 240 and 740 love those old school bricks proper volvo those!
I had mitchelin cross climate few years back on the prius the sidewalls were really weak had to replace them under 20k!
The worst tyres I've ever had were Avon zz3. Had a issue twice with them. Once in my mrk2 mr2 and a blowout on my e34 5 series bmw.
After that's would never touch Avon ever again! 👍
