Is it normal that on my 500h.o
since day 1 i need to put air in my tires every time? I always put 5 pounds. when i go to ride it the following week it is down to 1 or none. on all 4 tires. Should i go back to the dealer with this problem?

also how much air preasure is normal? in the book it says 5 just wondering what others put.

 

They should maintain 5 pounds, but since you live in Quebec, is it cold when you are checking pressures? Is it cold when you fill the tires? 5 pounds is very low pressure and it will easily fluctuate due to temperature.

One thing I would suggest is that you are using a good tire guage. If all 4 tires are dropping pressures, that seems strange. I would take it to the dealer.

 

It is not uncommon for tires (from all manufactures) to go flat right from the showrrom floor. It could be from a bead that is not seated all the way, or even dirt or debri in the bead area. I would take the tire off, pump it full of air, and submerge it in a tank of water and see where you are leaking from

 

mine did that too ... broke the bead and reset it still did it so i just put tubes in them all. 32 bucks for tubes... i guess its better then havin to pump them up every time i go riding

 

Mine too!
I just put 8 ounces of Slime into each tire, pumped them up to 8 - 10 psi, and swished the tire around until I got the Slime all round both beads (inside). (Obviously, you need to have them OFF the bike - Duh!)
Let them sit for a few hours, adjust the tire pressure, and go riding.
This cured my five to one pound overnight pressure drop.
Just about every tire shop has some black "bead sealant" that could be used in this situation, too.
