To all Merry Christmas and a Happy New Year. I just dumped as chuck of change for 6 new 8R19.5 Samson china tires and looking for some advise to keep them from checking or cracking. I know to keep the tires out of direct sun light for long periods of time, and use them so they don't get flat spots. I'm looking for a product or solution that will not take the compounds out and dry the rubber out. I found some products make the tire look great then turn the tire into a junky, where you have to keep using the product or the sidewalls fade fast and crack fast i.e. ARMORALL. Thank you
