More or less the same here.

It's the same reason why I had to change my front rotors at 65000km while some riders are still on the original items at twice the mileage. wink

Your in WNC and I'm in NFL. Lots more straights down here. Also, there have been long trips out west, three for the front and two for the rear. Lots more straight roads.

I believe the high mileage in some parts of the US is due to the local rock used in the pavement mix. In areas where river rock is used, tyre life tends to be highest. In areas where hard angular rock is used in the mix, tyre life is lower. I would also expect an inverse relationship to traction.
Just my theory.


Red,
Give me ambiguity or give me something else.

The chip and seal roads in the Texas Hill Country are like riding on sandpaper!

I consider myself lucky if I get 5k out of a rear tyre....!

When I rode out to Redmond, OR for the MOA Rally, I noticed that the rocks used on roads in OR were very, very abrasive and the tire wear visibly increased.

My riding buddy always got a lot more miles out of a set of tires on his RT than I did. Why? He was very, very smooth in acceleration and braking. Light throttle hand.

Me? Full start, full stop.

So I'm always scrubbing rubber of the tires.

I haven't had too many Beemers, I just don't have enough time.

Oh so true. I rode my KRS (freshly clad with Pilot Powers) to a K-bike rally in Hill Country and ate up almost 2/3 their tread life in only 2800 total miles. Not only that, I witnessed three tire failures while at that rally - all three riders thought they'd have ample tread to do the round trip.

Aside from that, I've since transitioned to the PR3 and then PR4 and any spirited riding on my K12s renders the tread life to that of a mortal smile tire. Still, I love the grip and ride and can't wait to throw a set of PR4's on the RT!

Changed out the front PR3 for PRGT on my K1300GT today at almost exactly 7000 miles. I'm very pleased with the milage, considering the weight of the bike, rider (250), and riding style. The loss of profile and cupping only became apparent after the last 1000 or so miles. Surprisingly, I noticed little change in transition from side to side, even with the flattened contour. Curious to see how the stiffer GT hold up. I'm much more aware, and ready to change the rear, when the profile is lost. By far the best handling and durable tire I have used. I'll try to remember to post photos of the rear
GT as it wears...still fairly new.

Now at 16K on the front and 13K on the rear. Pretty much shot.






Don't like 'em so much when they are worn - they follow grooves/stripes in pavement and you can feel the shoulder when tipping it over. Cornering is still good but I can't wait to mount new tires. Will be PR4 GTs as the first 10K miles more than outweighs the last 2-3K miles.

So my 2013 RT came with Bridgestones which sucked. I put on a set of GTs at 6,500 miles. They've got 7,800 miles on them now and look like photos below. I should get 12k out of them at least. I run higher pressures than most...seems to work.

Last report.

Put another 500 miles on this set last weekend and when asked how the bike was handling, "Evil" came to mind. Was not much fun as the front would follow any groove or imperfection in the pavement.

Here is the rear at 13.5K miles:



It could probably go another 1-2K miles.

And the front at 16.4K miles:



The left side of the tire is pretty smooth; no wonder left sweepers were not much fun chasing Bernie to SECFF.

I'm finally done and have a new set sitting in the garage. Can't wait.
