Tire Pressure.

[Jarred]

Good morning all. I’ve searched for an answer to this question but can’t find it.
‘According to my manual, rear tire should be 28 PSI-no lower than 26psi, no greater than 30psi.
‘I’ve noticed w Fobo in the morning (before riding) my pressure is only 25.5psi (setting off the alarm for under inflating) but after riding a bit it goes up to 28-29psi. If I inflate it to 28 before riding, the alarm will go off after a few miles stating that tire is over inflated.
So what’s the correct “time” to confirm tire pressure, before ride or during?
‘Lots of talk on tire replacement so I want to make sure I’m maintaining my new tires properly.
‘Thanks SpYder Friends.

I've always check my tire pressures cold, that's the way I've always been told to do it. I'm sure others with more knowledge than me will chime in. Dale

Always cold.

Always cold.

Thanks everyone! I’ll add air now.

I love this page, everyone is so helpful. I’ve owned my Spyder only 3 weeks and love it!
Ive learned so much from you guys/gals.
Have a great Sunday.

What you have mentioned about the rear tires is called ballooning. As the tire heats up, the center balloons more than the rest of the tread. This leads to the early wear of the rear tires in the center.

I have been using 26# for cold pressure. At about 18K, the Kenda's still have good center tread, compared to when I used 28# cold.

In the past, 15K was pretty much tops for rear tire mileage on my Kendas.

You can change the limits on your FOBO so the alarm isn’t always going off. Just be sure to check the FOBO before you leave on a ride.

yes that's the way you check air pressure when it cold. The normal is that for every mile you drive adds 1 pound of air to the tire pressure.

Really .... So what happens if you drive 100 miles ...... Maybe you want to change that ...However I know two recent posters who might just take that as Gospel .................Mike

I heard that from a tire guy one time. I kinda thought he had lost his mind to.but he swore it was true during hot weather. That is why you check tires when they are cold to stabilize the tire pressure before you take off riding. Sorry if I concussed anyone.

No that's not right at all.
Think about it for a minute.

Yes, stone cold.
