Tires haven't been my problem, it's been the wheels. Stock wheels exploded on 6s so I tried DE Racing Trinidad sc wheels and proline trencher tires. Much better, but the Trinidads end up cracking. Now I'm running the same tires on DE Racing Borrego wheels. The Borrego wheel is stiff with a lot of internal webbing. I couldn't imagine there being a stronger wheel out there.
