Michelin tyres have 'high silica' rubber compound, which I believe they first used in their motorbike tyres, which gives better grip and more flexible tread and sidewalls, and also hard wearing and quiet. Wanli tyres are probably recycled bean sprouts, water chestnuts and Tofu with a dash of soy sauce to give them colour.
The original Japanese Bridgestone and Yokohama tyres of 60's as fitted to Jap motorbikes and cars were made of a strange low friction plastic compound, were lethal in the wet and hard wearing - but the reason for that was that Japanese roads were covered with a much grippier surface than our roads are, a bit like the shell grit found on approaches to road islands in UK (in Japan maybe made from volcanic ash from mount Fuji). Just shows that what you need are tyres made for the road conditions in each country, rather than shipping tyres halfway around the world from countries where the conditions (heat, cold, rain road surface etc.) may be entirely different.
