air pressure

Postby Maddogg » Mon Oct 07, 2013 6:14 pm



Okay. I posted this somewhere before recently, but can't seem to find it. I am running 41 lbs of pressure in my tires. I have Dulop Elite 3's. Side of tire says 41 cold, on both tires. I was running about 26 lbs in each tire but I was worried about bad gas mileage. The ride was fine at 26 lbs. I listened to everyone and was getting rcommendations all over the board. I inflated to 41 and now I feel every rock and bump in the road. Way to rough. Thinking about going back to a lower pressure. What am I sacraficing when I go back to 26? I am running 10 psi in my rear air shocks. Single rider weighing in at 210 lbs.

I run 40 in the rear and 10 or less in shocks. Only weigh 175 pounds and under 5' 8". Ride is better with 25-30 psi in shocks, but that only works for me when 2 up riding. Legs are too short.

A real difference is felt at 36-38psi in rear tire and 90% of bump will go away.

Thanks Robb, I am gonna bump the pressure back down. It seems to ride smoother at lower pressure. I also run 10 lbs in the rear shock unless I have the wife on board, then I run about 40.

I would follow the manufacturer's recommendation for proper tire inflation. While your bike may ride better with less air, low tire pressure will cause your tires to run hotter and I'm not sure how it would effect handling. I would continue to investigate the suspension system. With proper tire inflation and running 18 psi in the rear shock, my 1990SE almost floated is was so smooth.

My tires are cupped so badly that the bike wobbles at speeds between 20 and 25. I was told the cupping came about because I ran it with low tire pressure.
BTW, I have 18,000 on my rear tire, which is a SHINKO, and it looks like I'll get at least 2,000 more. If I can put up with the wobble. I normaly run it at 41psi, but I let it get down to just over 30 and ran it for at least a week. That's when the cupping happened.
