No the same rubber.Thailand makes good tires. They will not cheapened out on making rubber tires because they're the rubber tree capital of the world.
Yes, with few exceptions. Mixed with chemicals (man made technology) added, tires still have natural rubber added to it.No the same rubber.
For sure, but the majority of what makes a modern tire is the chemical compound science and R&D which most new companies don't have, because main stream companies have had centuries to work on this stuff. I know, because michelin headquarters is down the road from me with what...like 4 (nvm just checked, 5) plants. Talked to many of the engineers there, and although rubber is used, the part that really gives the tires their specific qualities (summer, track, all season, winter, etc) is the over all compound chemistry. Think "base oil" and then friction modifiers, viscosity modifiers, and so on, in engine oil. If you compare a main stream brand to a no name brand, it doesn't matter that they have access to "the best rubber" when the main stream brand also has access to that same rubber, but knows how to make a better tire.Yes, with few exceptions.
