I have to say Im really happy getting 17300 out of the stock tires on my 2010 flhx. I never do burnouts but ride very agressive in the corners and accell hard from stops. Every other tire I have used was shot at 6000-7000 miles.
I am putting the same dunlops back on. The local dealer had a special for 363.01 installed.

 

I have averages 27k out og the D402 tire on my 08 roadglide. I get about 11 month use out of them. Just put my 3rd rear tire on. I did loose one each front and rear due to punctures. But milage wise they are tops in my book.
My last 2 tire changes i took wheels of bike and took them in.$135 M&B front and $180Rear. The guys at Latus motors fixed my up on mounting and balance in 45 min. Beats leaving the bike in the shop for 3 days. My bike crys if it isnt riden daily

 

I changed my rear at 14K just before going to Sturgis. Could of got another couple thousand out of it for sure.

 

My 09 Classic got 15,000 out of the first rear and I am at 22,000 and the front has got another 3,000 to 5,000 left. I will stick with the factory tires.

 

33k on my stock front .... rear was changed at 17k
Very satisfied with stock Dunlops on my '08.

Maintain tire pressure and no burn outs....

 

+1... I got about the same mileage as You with the stock dunlop's. (08UC) I will keep running the Dunlop's, can't see getting only 6 or 7K of other Tires.

 

I've got 29500 miles on my original d402 rear (08 RK).Just about ready to replace.Front still good for awhile.I'm not an aggressive rider and watch pressures.Will definately go with 402's again.
