I have Shinko SR712 H rated in 110/90-19 front and 120/90-18 rear. I got conflicting conversions on tire size, so that's how I wound up with 110/90 on front. Fits, but looks too big.
I have put 1000 miles on them, but no wet weather riding. My bike had the original dry rotted tires when I got it, so I have no comparison. They seem to wear well and stick pretty good. The front tire is out of round, and it's irritating at about 40mph.
I work at a auto tire shop, and no one seems to make a round car tire. I would have thought bike tires would be better. I have rotated the tire on the rim and it didn't help, the rim is true, and the bead is fully seated. Next time I will spend a little more for a decent brand.
