We have to get all new tires for a 2004 Coachman Mirada 30'. We are told they will cost about $2500. Does that sound right? We live in the Bay Area. Anyone know of any places that sell tires for a decent price? This RV is new to us, 15,000 miles on it and it has some brake issues and the roof needs repairing, as well as a couple of other cosmetic things (not a priority) so we are trying to do the repairs the most economical way we are able. Thank you for your help!
