I fairly certain that you will hear from two groups...those that advocate having the tires on wood rather than concrete or asphalt and those that don't worry about it.
Since my rigs have been stored away from my house for years, I've never worried about it. My thoughts are that it isn't a problem as I'm a believer in replacing tires every five to seven years.
Retired but busier than ever!
