We do it. We went to the Escapee's Boot Camp and a retired tire engineer from Goodyear said UV rays are very hard on trailer tires. He also suggested that if you are parked on concrete for any length of time that you put cheap plastic placemats under each tire so it doesn't contact the concrete. He said that chemicals in the concrete work on the anti aging chemicals in the tires and that's why you sometime see black marks on concrete where tires sit for a long time. We don't put the covers on the tires if we are just staying for a week or so (depending on angles the slides help cover them), but when we're parked in AZ for the winter of KS for the summer they go on right away.
