Just for info... I think it is good to help my tires any way I can when in storage state. Whether it actually helps or not, well I don't know and just feel better about it. That said, here is an idea for you all. I was getting some parts from my local O'Riellys store and they were throwing out their mats they walk on behind the counter. They are extremely heavy rubber and thick. I ask if I could have them and they said sure, we are just chunking them. I used one to line my truck bed, the other I cut into very large mats for my RV on my gravel drive. The rest I use for a mat to lay down if I need to crawl around under my rig. cant bet FREE!!!
