Both tires on a Genuine Buddy 125 call for the same cold pressure: 26 psi front and 26 psi rear. Most people expect a scooter's rear tire to want more air than the front, and this one doesn't. That is the first hint that 26 is a baseline, not a universal setting, and it changes the order you should inspect in.
The owner's manual sets that baseline and asks for the check while the tires are cold. This guide stays inside that manual and that model.
Why Cold Pressure Comes First
Perform the check while the tires are cold, with the valve caps off, then read the gauge; that is the manual's order. Cold is not a convenience note. Air pressure climbs as tire temperature climbs, so a tire that has just run a few miles reads higher than the same tire sitting overnight, which means a gauge number is only comparable to a cold spec when the tire is actually cold. A warm reading against 26 psi tells you nothing useful.
Because of that, the check belongs at the start of the day, or after the scooter has sat long enough to come back to ambient. If the scooter must be moved first, moving it by hand keeps the tire close to cold in a way that riding it does not.
The valve caps are part of the job, not packaging. They keep grit and water out of the valve core, and the manual calls for reinstalling them once the pressure is set. A cap left off leaves the core exposed to whatever the road throws at it.
Inspect Both Tires for Lodged Debris
A physical inspection of both the front and rear tire is what the manual asks for, looking for foreign material such as nails, screws, glass, or other objects that may have become lodged in the tire. Both of them, front and rear, every time.
The reason this is a separate step from the gauge is that a nail or a screw can plug the hole it made. The tire holds air, the gauge reads normal, and the object is still sitting in the tread. A good pressure reading proves the tire is holding air at that moment; it says nothing about whether something is embedded in the rubber waiting to work its way through.
Physical means the whole circumference, so the wheel has to come around between looks. Work around each tire rather than glancing at whatever faces you.
The manual's word is inspect. It does not tell you to pull the object out and keep riding. Whether a punctured tire gets repaired or replaced belongs to the model's own service information or a qualified technician, because yanking a screw at the curb can turn a slow leak into a flat with no warning.
Read Tread Wear Indicators Correctly
Tread wear indicators get misread because they live down inside the groove. Move inward toward the center of the tire to find the raised portion of the tire groove; that raised bar is the indicator, and it is the reference point, not the tread around it.
Because the indicator sits below the tread surface when the tire is new, it only becomes a limit once the surrounding rubber has worn down to its level. The replacement rule is contact: replace the tire when the tread wear indicators come in contact with the road surface. Which means 'it still has tread on it' is not the test. Every worn tire still has some tread on it somewhere, and the indicator is what tells you where the line actually sits.
Read it in more than one spot. Wear rarely reads the same at every point around the circumference, and the indicator that matters is the one closest to contact; a tire that passes at one point and fails at another fails. This manual's rule is contact with the road surface, and it stops there. It hands you no millimeter figure, so don't invent one, and don't let an argument about depth gauges talk you past a visible indicator.
Set Pressure Around the Load
The manual gives a standard 26 psi front and rear, then tells you to adjust the tire pressure according to the total weight load. Those two sentences belong together. Because the air in the tire is what carries the load, the same cold gauge reading can be right for a solo rider and wrong for a scooter loaded with a passenger and cargo.
The load limit is the hard edge of this section, and the manual states it without hedging: never exceed the rated total weight or the bearing capacity of the tires. That is a limit on the vehicle and on the tires themselves, and no pressure adjustment buys you past it.
Before you judge a reading, know what was on the scooter. Write the load down beside the psi. A fleet log with two numbers per machine, pressure and load, tells a mechanic something a pressure log alone cannot; it separates a tire that is losing air from a tire that was set for a different day's work.
The quoted instruction stops at 'adjust according to total weight load.' If you need a pressure figure for one specific load case, that figure has to come from the model's own documentation or from the tire sidewall, not from arithmetic someone made up on a forum thread.
What Confirms the Inspection Is Complete
Finishing a tire inspection is not the same as having looked at the tires. At the end of the job you should be able to point to six things.
Both tires were physically inspected, front and rear. Pressure was checked cold with the valve caps off, and the caps went back on afterward. The reading was compared against the 26 psi baseline and adjusted for the load the scooter was actually carrying. No nail, screw, glass, or other lodged object turned up, or the uncertainty was written down and handed to the owner or a technician instead of being shrugged off. The tread wear indicator was not in contact with the road surface, or the tire was flagged for replacement. And the load did not exceed the rated total weight or the tire bearing capacity.
Miss any of those six and what you did was a glance. That line matters most on a fleet, where the next rider inherits whatever the last check did or did not establish.
Where the Buddy 125 Manual Stops
Everything above is tied to one document: the Genuine Buddy 125 US owner manual. Model scope matters here because pressure, load, and wear rules are written for a specific tire on a specific vehicle with specific equipment installed.
The reason not to carry 26 psi onto another custom moped-style scooter is straightforward: a different build can run different tires, different wheels, and a different loading envelope, and 26 psi would then be a number with nothing behind it. Confirm the exact version and the parts actually fitted before applying any of it.
These specifications also do not establish a legal moped class. Whether a scooter gets registered, insured, or ridden under moped rules is a separate question from what its tires want, and one manual's tire table does not settle it. For another model, use that model's manual and the markings on the rubber that is on it now.
When Time Is Short, Check Pressure and Tread First
With a short window on a fleet scooter, the first pass I would spend goes to cold pressure and to tread wear indicator contact. Those two checks turn 'looks fine' into a number and into a replace-or-keep signal, and both of them degrade in ways you cannot see from ten feet away across the shop.
That ordering is about attention, not permission. It does not make the physical check for lodged debris optional, because a screw sitting quietly in the tread passes both of those fast checks and still ends the day as a flat. It does not make the load limit optional either. If the short pass turns up a problem, or nobody can say what the scooter was carrying, the full inspection applies and the machine waits.
If you take one thing out of this today, make it the gauge and a pen. The next time the scooter sits cold, measure both tires, write the psi and the load side by side, and only then decide whether anything else needs a closer look.
