Nope, GP-1's are the tires Kenda cloned for the K270. GP-110's have wider rectangular
blocks with a "hook" on the end.
A lot of people run the GP-110's reversed in the first place, because their tread pattern is
such that they allow better braking force if reversed so that the hook is "leading" rather
than "trailing". What also helps is running them at *high* pressures on the street. As in, as
high as is printed on the sidewall.
That said, any dirt-oriented tire is eventually going to get this sort of wear pattern on the
street unless you rotate them every 1,000 miles or so to point the other direction. Which is
a PITA. Frankly, my time required to swap the direction my front tire is rotating is worth
more than the cost of a new front tire when it gets cupped. I just change the front tire
when I change the rear tire, and avoid the question altogether.
Oh, regarding braking -- on the street, the rear brake is used to adjust attitude but
doesn't provide significant braking force (if using both brakes to their max, the back will
provide maybe 20% of the braking force). In MSF class they taught us that the front brake
should be the primary brake you use on the street, not the back brake. The old notion
that the front brake could somehow "fling you over the handlebars" is a debunked old
wive's tale, not something based on anything that has actually happened, especially if
you're talking about the rear-heavy lead sled cruisers whose riders often parrot such
nonsense. On the street I use the rear brake to control nose dive and that final "bounce"
you get when you finally stop if you brake with front brake only, but it is the front brake
that I rely upon to stop me.
