There are quite a few vinyl tire and wheel covers available, but none of them are truly canvas material. I see you were looking at the Classic Accessories RV Wheel Covers - Model 6 40"- 42" (bus size) Snow White # 052963762709; these are for 40" - 42" tires and they are made of vinyl fabric. I attached a link to the various tire covers available on our site that you can check out; simply click on your tire diameter and you will find compatible covers. view full answer...
