The D408 front tire says 41 PSI. I'd like to know how many of you pressure up your tires to the maximum tire pressure. I have 25 PSI in my front tire, and it seems to be hard. Would you recommend upping the pressure to 41, or a lesser pressure?

 

What do you think?

 

I would at least have 38-40 in it. I run the max in my tires.

 

I run 40 in both (and around 20-25 in the shocks, while we're on the subject).

25 is dangerously low... Unless it's some freaky tire I don't know about...

 

I got a 21" Metz and it says 42 max. Anything less seems to look flat and feel mushy. Now if I could only get my hog pro wheels to hold the pressure.

 

I always run the max air pressure and check weekly

Motorcycle Consumer News magazine had something on this a while back. If you run the tires low they run hotter and wear out quicker while risking a flat. If I remember right they recommended running the tires just under the max reading. My tires have a 41 max psi and I run them between 35 and 38 psi.

 

The book says 36 lbs front, 40 rear (at least for the stock tires).

 

I run what the owner's manual calls for. The tire pressure stamped on the side of a tire is the maximum pressure that you should ever have in that tire for safety reasons. I'm sure there is some built in fudge there.

The only professional vehicles that run that max pressure are OTR 18 wheelers and some buses, as well as motorhome bus conversions like Prevost. And you have probably noticed OTR truck rubber on the road. The truckers do it to carry a maximum pay load. I see no eason to ever run the max pressure on a motorcycle unless you are doing a run for maximum mph.

My 07 RK owner's manual and service manual call for 36 psi front and 40 psi rear for two up riding and that is what I always run even though I seldom ride two up.

Check your manual. I think 25 psi is dangerously low in your front.
