How in the heck are you guys/gals getting big mileage out of a rear tire. I have run Shinko 712, Avon Road Riders, Shinko 244's and no matter I'm lucky to get 3000 out of a rear.
I'm not familiar with Shinko 712 or Avon Road Riders. Seems to me a road oriented rear tire should easily go beyond 5K miles.
I've run the Shinko 244. YES, 244 rear tire miles not great, I got 3,500 miles. It wasn't bald but clearly center worn. Mixed riding, but mostly ROAD riding on nasty twisty roads ridden at speed. Also, freeway miles at 70 mph ... which are a killer.
Lots depends on type of riding and road speed. Avon Distanzia and Michelin Anakee, I got over 5K miles on both. Distanzia a bit better than Anakee on longevity.
I got 2000-2500 miles on OEM Trail Wing rears. Best distance on a dual sport (50/50) tire so far is $60 Kenda K70 which went beyond 6,000 miles.
Sure, by 5000 center was squared off but still safe and performed OK, not great, just OK.
A good test of tire design is how well a tire works once worn down 80% of it's life. Some tires turn to crap handling wise at 50% worn, others go further.
Certain things wear tires quickly. Number one is SPEED. On long trips where I have to make rear tire last I keep highway speeds lower.
I normally ride at 70 mph (65 mph actual). On a LONG ride I drop that to 55 or 60 actual. Tire wear is really extended in my experience.
Like from 3500 mi. rear tire up over 5000 mi. In the old days when tires didn't last well guys in my riding group would totally wear out a NEW rear tire in a weekend. (under 2000 miles) This on sport bikes riding CA Highway 36 and other fast, twisty roads at speed. Tires are better now. But high speed and hard acceleration still will wear them early.
