I have pointed out, along with temperature data, in my blog post on why white tire covers are good and much better than black covers.
This shot shows what can happen with a black cover that effectively places the spare in an "oven" where cooling air can't offset any of the Sun's heat.
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.
These folks do it right.
I know of no tire shine or protectant spray that provided protection from heat.

Hadn't really thought about that but it makes perfect sense. We replaced ours with black because 1) that's what it came with and 2) it matches the trailer. I will be looking today for a light colored cover similar to those we use on the tires on the axles. Good food for thought.
Edit: Just ordered a new, lighter spare cover - don't want my "new" Carlisle spare to bake sitting on the spare mount.....
