I have Parnelli Jones Dirt Grip tires on my truck. Aside from having some balancing issues I have been happy with them. They make very little noise on the road, offer a smooth ride, and will take you anywere you want to go off road. The MTR's that yo are looking at are supposed to be a good all around tire. But are pretty hard to find right now, which is bad is you blow out a tire and have to track down another.
This website has all the availible tires for the H1 and might make your choice a bit easier.
