Tire cover for dual wheel

[Solbkeston]

I bought a Precept class A in September and want to buy tire covers since it's stored outside. I found articles about sizing and brands, but nothing about how to cover dual wheel tires. I do not mean dual axle, but where there are two tires on each side on the same axle. Do I just cover the outer one, buy 2 covers for each side of the axle (not sure how you would put on the inner one, or do they make a cover that covers both wheels?

I just cover all 4 outers since the inners are not really exposed to sun etc...

Menards sells a silver colored tarp. Get a small one and put it over the inside tire, use a standard one on the outer tire. Or, if you don't care just use a tarp over both tires.

Make sure there is room to breath so water and rust don't start on your wheels and brakes.
