lpb,
The next size up is 305/50/15 (27" tall, 12" wide). It's no longer made (for years), but was made in BFG Euro T/A. These tires can still be found NOS, but I haven't seen any for sale in a long time. Try the vendors.
1973UFO on the PIBB (Bob), had a pair of these tires with 1500 miles on them for sale in Dec of last year. He may still have them. Here's the link to the thread:
