I ride a 2010 Ultra Limited 50/50 solo and 2 up.
Don't ride it like I stole it.
Don't do burn outs.
Don't usually cruise over 70 mph.
Mix of 50/50 highway and country roads.
How much mileage should I get out of my stock HD Dunlops?

 

You are going to get answers all over the board...from 6000 to 16000 out of the rear tire

The three main variables are-

1. Riding style
2. Maintaining proper air pressure
3. Condition of the road surfaces you ride on

I have never gotten over 8500 out of my rear tire and 20000 out of my front.

I maintain proper air pressure
Ride somewhat aggressively (using front brake far more than rear)
Ride on a lot of poor road surfaces

 

Everyone is different. For me get about 13,000- 15,000 miles out of the rear, double that for the front. Two rear tires to one Front. Pull a trailer,2 up most of the time. The faster you go the faster the tire wears.

 

My 2011 Limited has 18,500 on the tires and the rear will probably go another 2,000 or 3,000. The front is approx 50% worn. A lot of folks would have replaced at least the rear by now, but I run them until they're gone (1/32 or less).

I'll typically run around 10 MPH over the limit on long rides. On my last road trip of 9,000 miles I'd say my average cruising speed when on the Interstates was 80 - 85 MPH.

These 407s/408s are the longest wearing tires I've ever had by a longshot.

 

I have replaced the rear on my '09 UC twice, at 17,000 and 18,000 miles. I changed my front at 29,000. Have 46,000 on her now and plenty of meat left front and rear.

 

I have the same bike and my front tire still looks like new after 10k but i am changing out my rear this weekend only because of the cupping and i check my air all the time. Hope the dunlop elite takes care of the cupping but only time will tell.

 

I put 17,000 miles on my '10 Street Glide before I traded it in. The rear was ready to be changed, the front still looked good.

 

On my D402's I avg about 17k on a rear and 35 on the front. I just replaced another rear over the summer and that one had over 20k on it and still had some meat left.

 

usually 10 - 12k on rear, and 18 - 20k on front.

 

You will get lots of different answers because tire longevity depends on many factors.
I replaced my rear D407 at 12,000 miles and it had 2/32 left. I could have put another 1,500 miles on it if I had to but I felt it wasn't worth taking the risk.
We ride duo all the time and the roads in PA are tough on tires.
