I found a guy who has great deals on bus parts and tires.He's in Wisconsin. His name is Tim and you can reach him at 608-387-5160 or on ebay under member name suhanich123
I once blew the front tire on my Harley at about 50 mph, nearly messed my pants and almost gave up riding! To stay on topic, I have never heard of speeding up, just hold on tight and let it come to a crawl on it's own ( no brakes)is my advice. By the way, Hi! I'm a former lurker now a member and the proud owner of an '91 blue bird
Hope this helps, Willy
