I was thinking if you sprayed your Rv tires with rubber roof conditioner would if it would help I put covers on mine but thinking of spraying them too !
I'm not sure about the roof conditioner, but I have heard that the covers inhibit airflow around the wheels which results in brake system corrosion and other issues.

After I tossed a set of Michelin LT's with 6000 miles on them I started using 303 and cotton lined white covers. Now that we are on the road, I no longer use the covers. 303 is great for the slide and compartment seals as well. I don't use it on the EPDM as I have not looked into that or contacted Dicor as of this date.
Well, as it turns out, the claim is from Dicor themselves. I did find something very interesting though.
In one document, you can scroll to the bottom and see this:
Q: The rubber roofing wraps over slightly on both sides of my RV and you can see it from the ground. It gets dirty and doesn't look good. What can I do about this?
A: Clean the area and treat it with a product that will repel soiling and is safe for EPDM. One product that performs and lasts well, is safe for EPDM and is commonly available at RV stores is 303 Protectant.
In another, it changes to this:
