I need recommendations on whether to buy taller and/or wider tires for my '83 Vanagon Westy, but I don't want to bother anyone because I know this has been discussed, probably ad nauseam, so if someone could simply show me the 'search' engine for this list, I'd appreciate it.
The tire man, who comes highly recommended by the pool supply folks, said to match what I have on there now I should get Uniroyal Tiger Pav? (cant read the last word--maybe an abbreviation for 'pavement."?  Part number 21570R14 (again, hard to decipher).  He said they are guaranteed for 64K miles and would cost me with the change and the balancing and so on $427.79.

But I'm wondering about the advisability and possible utility of larger tires, both taller and wider, without changing wheels.  Thanks so much for any help, particularly in searching the archives.

Best,

Bob
