Should I cover my tires?

Well said GDE. Bravo!

OP, winter, in PA? I wouldn't even consider it.

Summer in AZ? My answer would be exactly opposite.

What's contact with the ground do?

Old wives tales and folklore that tires sitting on bare ground will be damaged or go bad.

Same vein as needing to periodically take your RV around the block to redistrubute the oils in the tires to prevent them from drying out.

Covering the tires is also one of those RV folklures..

To answer the OPs question, cover if it makes you feel better. But in reality, covering has little to zero benefit. Buying premade covers is a waste of money and the onl person that benefits is the sales person.

I have tires on antique vehicles and even a few tractors that are garage queens, very little daylight gets in the garage due to a couple of small windows.. The tires eventually crack and check as they age, you can't stop it, can't slow it down. That is the nature of rubber.

The rubber naturally ages out over time with or without UV exposure and generally with tires on RVs the best thing is to replace them every 6 yrs or if you find checking and cracking.

As far as putting something under the tires, no need, but it is helpful to keep the tires from naturally sinking into the dirt provided the item you put under the tire is much wider than the tires.

If I stop for more than three days I cover at least the sunny side. For winter, all are covered.

If you’re not going to use it until spring, perhaps you should cover them. But first … clean them really well, inflate them to sidewall pressure numbers, and perhaps put something under them so they are not in contact with the ground.

Yes

If they get a lot of sun, yeah.
