Dunlop 606/ MT21 Combo at 15 PSI

I just put Dunlop 606 on rear and MT21 front.  They are fantastic in the dirt, rocks, trails,etc.  On the road they grip well but are loud.  I travel about 10 miles on the road with 60MPH speed limit to get to the trails.  I have yet to take them past 60MPH.  They are loud and  sound like they might come apart.  Here again I am at 15 PSI.  When I get home, the back tire is pretty warm which is normal at that PSI.  Im sure a lot of you ride this combo.  How fast do you feel comfortable going on them.  I think most of the sound is comming from the rear.

If you plan on running high speed on pavement for any length of time I would bring the air pressure up to about 25 psi. If going back and forth between dirt and pavement then 18 to 20 is a good compromise - unless you have some sort of fetish about air down and pumping up tires whenever you change substrate.

I use to run a 606 rear and have had it up to 93 mph on an Interstate for a few miles. Typically though I would be around 75 to 80 mph on the Interstate when I am trying to make up ground. If I am going to do that I will make sure to up the air pressure. Running high speeds at low pressure on a tire is a receipt for a f'd up day.

Agreed. If you want to run that low of a pressure, air up for the ride out and let it out when you get to the trails. Bring a pump to get them back up to road PSI or take it easy and go slow for the ride home.

I get mine up to (my) vmax all the time (120km/h 75mph) with no issue, but I run the Yamaha recommended street pressures when on the street.

Yea that makes good sense.  Air them up for the road.  Ill look for a pump to carry. Thanks

I carry a small bicycle pump on my bike for emergency use. Works but it does take awhile to get it up to the right pressure.

Typically if I am coming off a trail and know I will be covering pavement at speed I will just pull into a service station and air up there rather than spend a lot of time pumping away.

As an alternative there are some small electrical tire pumps that can run off a SAE connection if you don't mind carrying something bigger.
