Welcome to iRV2. Theis was your first best idea for learning about rving. Just spend time here and ask alot of questions. You can also search the site for topics, like tires, and find goodles of opinions and clues. I bought my tires from SimpleTire.com, who shipped them to the the local Les Schwab dealer who ah\\had already quoted me a price to instal them. BOOM, tire clue, but there are alot more on this site about tires, and where to vernite, and etiquite in a WalMart parking lot, and why my grey water stinks, and which tv to replace my old ones, and on and on and on......
