I just got this email from Galaxy. Check this out. Good morning, Thank you for your e-mail and your interest in our Brawler Solid Flex tires. In most cases, the Solid Flex tires can be “flipped” … we would need to know the Model of the Case skid steer to be certain; however, I’ve been advised that running tracks on our Solid Flex tires would nullify the warranty on these tires. Regards, This was signed by the director of marketing. I left his name off but there it is. Anyone else just a little surprised? A runflat tire that is not compatible with steel tracks? Seems a little crazy to me.
