Very Strange considering both Rockets use the same wheel and tire sizes???
The three Road 5 tires I have used have worn very evenly on both of my R3Rs.
I shall start out with new tires, so it shall be interesting to see how the tire wear goes on my 10,000 mile + cross country run in search of the twisties this June.
My last cross country romp was 11,500 miles and required 3 tire changes (1 front & 2 rear) along the way, but it did not involve the use of a Road 5.
