Tire presure
« on: June 08, 2012, 06:58:49 PM »
My scoot says (yes she talks to me) my front tire should be at 1.5c and rear should be 1.75c max for 1 rider. I did a conversion online and it comes up with (rounded) to 21 lbs in front and 25 lbs in the rear.

Sounds right to me but I wanted  to make sure you all agree.

You will have more usable power , get better gas milage , and better handling with 30-32 psi . maybe a little less in the front than back . Good lujck .

Thank you, however I like to stick with the Manufactures guidelines, I'm mostly looking to make sure my conversions are correct.

Can anyone confirm this for me?

With rounding I calculate 22 front and 26 rear.  I like staying with the manufacturers suggestions most of the time as well.  On one of my scooters, if I go above suggested pressure in front, the front shakes badly.  Apparently, this is because the tire doesn't flatten out on the road as much allowing the front tire to move against the ground more easily.  Makes sense to me...

Manufacturer of the scoot or tire?  The manual was printed based on a general rule and is really not referring to a specific brand or model of tire. Some countries may use different tire brands/models. I experiment.

These values are similar to those of my gf'a Agility 125 (120-130/70/12 tires, I think).

Being your the closest to me in calculations I'm going with your suggestion, if that doesn't feel right I'll try a little more presure as suggested by DaveABQ

It also depends on the road conditions where you ride on a daily basis.

That is a free converter program that is the easiest to use, and accurate. It's also an Exe. program so there is no install.
The pressure is mandated by the Tire manufacturer. The ride comfort level is recommended by the Scooter manufacturer. The scoot people say the scoot performs best at whatever pressure, and The MAX inflation level is what is printed on the tire.

Tire valve caps with pressure indicators lets you visually inspect your tire pressure on every ride. A very useful accessory.

My gf had exactly these Chinese indicators on her A125. Stopped using them because they exerted pressure on valve pin and tire leaked air.
