This Shinko 244 is 2.75x21 (apparently only available in the States) has a P speed rating for 94mph. These tires are really good on the street and they're 50/50. They stick very well on pavement and off, I've only tried them in dry dirt and gravel, I hear they're bad in mud. Yes I built this wheel, it's a stock steel 21" rim from an RE Himalayan laced and trued by me to a stock RE Interceptor 650 front hub with custom length stainless spokes. After experimenting with tire pressures on this bike I like 24psi front and rear. I carry a $10 Walmart bicycle pump small enough to fit in a tank bag but can provide 40psi (eventually) if needed, but 24psi is good for all terrain I'll ever encounter, I'm not in the camp that claims airing down is necessary, no need to discuss that.
For highway riding, which I've done, this setup isn't as good as street tires. With my previous worn out stock Pirelli phantom sportscomps I did a top speed test and hit low 90s mph, with these Shinko 244s I don't really want to go much above 80, and I have no need to go much above 70 anyway.
