Trek 520 tires
I have a '94 Trek 520 that I bought new. I currently run with 700x38 Schwalbe Marathons on Rhyno Lite Sunrim wheels. If the 700 x 28s are working out ok for you on the roads you ride, then stay with what works, but around here on our not so great road surfaces the 28s probably wouldn't hold up very well. That would be especially true carrying a heavy load of panniers etc. '35s would probably be fine too.
