Hey guys,
What is the air pressure for 13" wheel? 130-60-13
Thanks,
Randy

What does the tin spec sheet on the scoot say?

[replyingto=doublert]doublert[/replyingto]I just put 28 in rear, and 22-23 in front. Hope that works correctly.

Never go by the spec sheets!
Look on the tire itself! Your only guarantee that it's good!
That being said, the standard for tires is 35PSI. You'll have to look on the tire if that number is higher or lower. usually it's never lower. But if it is (eg: 30PSI or 32PSI), you can still put 35PSI in, but it's better not to.
Most scooter tires have 35-40PSI max.

Always use the vehicle spec and make adjustments from there for load or speed.
The numbers on the side of a tire are the maximum pressure.
Example: Ford Exploder - vehicle spec says 26psi front and rear. I drove it and found it quite squidgy. I upped the pressures to 32psi and it rode much nicer and predictable. The current tires on that SUV have a max of 45psi on the sidewall. That would wear the center tread out and make it ride like a farm truck. Later found a service bulletin for 30 or 32 PSI for the Exploder.

Mine says 40 psi on the sidewall. It would ride like the Flintstone mobile! 35 in the rear and 25 in front keeps my fillings intact.

Go with what the tire specs are . And nothing else.

Go with what the tire specs are . And nothing else. That is so wrong, sorry. The tire spec is for max pressure. Motorcycle tires are not bike specific and tire pressure is not static. The pressure on the side as it was mentioned above is the max pressure not the correct pressure (it even says max not recommended). Tire pressure will vary from bike to bike as the load characteristics and amounts vary. Rider weight and cargo also change the required tire pressure. DO NOT USE THE PRESSURE RATING ON THE TIRE. Your current setting is probably close to the right setting you won't know until you ride it though. In order to tell you what the correct pressure is we would need to know the tire brand and exact size, the weight of the bike and how it is distributed and also the weight of a typical load (you and your gear/passenger) the engineers who designed the scoot should have already figured this out. I am certain the tire manufacturer didn't consider any of that when they stamped that max pressure on the side of the tire... |

The tire specs are indeed max rating. That's why you need to go with the tire specs!
On my EVO150 with 13" rims, it says 40PSI.
I know with weather conditions, my own weight on the bike, riding a long time so the tires get hot, the pressure can go up or down, and my meter could be incorrect.
Therefor I pump up the tires to 38PSI.
I ALWAYS go by the tire specs. It's clear from the specs that that's the max PSI, so it should also be clear not to overdo it.
Anyway, almost ALL scooters I've owned, once you hit 35PSI or lower, the ride become softer, wear out the tires faster as they heat up more, as they bend more, gets MPG and top speed down, downto 32PSI which is about the lowest I would keep it at.
If tire pressure is below 29PSI you can visually see that the tire needs air (shaped funny where it meets the road); your ride may be soft at 29PSI, but you'll not only lose MPG, top speed and performance, you'll also lose the tires much quicker (as they start bending and heating up, and cause hairline cracks in the rubber, causing miniscule leaks).
It's important to keep tire pressure as high as possible.
If you have 40PSI on the tire, and you put 40PSI in it, sit on it, ride it in hot weather, tire pressure could rise to 42PSI, which is what the tire should be able to handle just fine!
But I would recommend never to pump them upto max pressure, but stay 2PSI below it.

Prodigit sorry but that's wrong tires do not wear better at max pressure. The tire is designed to flex and wears best somewhere between too soft and too hard. Max pressure is almost always too hard and you will loose handling capabilities as well as the ability to stop as you have significantly decreased the size of your contact patch. The savings you get on increased mileage may cost you more than the cost of your accelerated wear on tires. The wrong pressure could be deadly... Be safe guys and spend some time off site researching maybe even the manufacturers' websites lets see who the engineers and science supports. Also read a few owners manuals if you can find one that says you should run the tire at max pressure in every situation I would be surprised.

other than what, 50 or 60??
