My new tire blocks to keep tires of ground and above casual ground water, w/vinyl tiles to keep pressure treatment chemicals away from tire tread, and plywood underneath to keep 2x12 boards from splitting. Thanks for all the suggestions

I would be careful about using vinyl tiles as vinyl always has some residual plasterizers in it. The plastetzier is what makes vinyl soft and pliable. The plastizer can attack the tires rubber. A better choice would be polyethylene or polypropylene. The polyolifins are known to be much more stable and inert. Water and chemicals do not attack polyolifins. I use polypropylene under my tires. IMHO

Hmmmm! Back to the drawing board
Don't know if I can find that type of tile and whatever I put on the blocks needs to withstand the movement of the tires without tearing or breaking. I guess I could just get 4 large plastic jack pads from CW and find a way to secure them to the blocks.

Go to the dollar store or other shop and buy white plastic cutting boards as they are polyethylene and usually about 1/4 inch thick. Good luck

Tell me more about your polypropylene. What form is it...sheet, tile, block, pad? And where did you obtain it.
Thanks

I purchased this black runner from Lowes. Easily cut into lengths needed for under the tires.

Shop black runner at Lowes.com: Search Results!

Since mine are on the ground and in the weather it was necessary to use pressure treated lumber here in Florida where we get so much rain. Else I would have to replace them every year.

On a flat surface like a concrete pad a runner is ideal. However, I have concerns about its durability on an elevated block where the tire has to roll onto and off of the block, creating stress on the runner material. JMHO
