So... I've been going quietly mad for weeks searching the 'bay for tan/skin walls, so thanks for this thread which is remarkably useful. I bought the Curio tyres earlier, they're on my Marin Bolinas Ridge pictured in BoM Aug '23. They are heavy but the grip is excellent for all applications. I also bought the cruiser style semi-slicks from them too and it's a really good on-road/gravel tyre though the sidewalls cracked badly while hung in the garage for a year. As I mainly do tracks out in the Cairngorms all year, I need full nobbly/high traction tyres so I've been hunting without much luck. I have a single Duro Vantage, was a pair until one sidewall went into a bulge. I think they are an ideal tyre for a retrobike but they have evaporated... for me, Tan/skin wall is the ONLY tyre which looks right on a older bike so I'll keep hunting.. IF I track anything down value/good I'll post on here..
