Tires: Winnebago, winnebago brave, stress marks

Question
I have a short wheelbase 27 foot 1995 winnebago brave. The motorhome only has 22,000 miles on it but the aged Michelin 8R 19.5 XZA tires now has stress marks on the sidewalls. Is there another tire with increased load capacity of at lease 3000 lbs that I can use with the about the same width & height. any help would be appreciated.

Answer
Bob,

You didn't say how old the tires were, but this sounds like either the tires are overloaded / underinflated or the tires are old.  

19.5" tires are honest to goodness truck tires, so you'll have to contact someone who deals with these types of tires to see what may be available.
