RV Tire Safety
with RV tire expert Roger Marble
I was recently reading a forum where the owners of one specific brand of trailers were complaining about the $21 the RV company wanted to charge for a spare tire cover.
I have previously covered in detail the advantages of and “why” we should be storing our tires inside or under our RV or under light-colored covers. It is the HEAT that kills tires, and the aging effect on tires is exponential (doubles for each 18° F). With such an increase in temperature, you could end up with a tire failure with ZERO miles, as seen in this example.
I pointed out, with temperature data, in the above-referenced blog post, why white tire covers are good and much better than black covers.
You will note that in both the above examples the top side of the tire (location with most direct sun heating) is the location of the failure.
I know of no tire shine or protectant spray that provides protection from heat.
