The Scooty Pep tyre pressure with one person aboard, checked cold, is 24 psi for the front tyre with 29 psi for the rear one. The Pep Plus carries 3.00-10 tyres at both ends, but the back one supports the engine and the rider's weight, so it needs more air than the front.
With a pillion on board, the rear needs extra air on top of that solo figure. Printed lists for that two up number differ from one another, so trust the Pep Plus owner's manual over a pump attendant's guess.

Scooty Pep Plus tyre pressure table
| Tyre | Size | Rider alone (cold) | Rider with pillion |

| Front | 3.00-10 | 24 psi | owner's manual |
| Rear | 3.00-10 | 29 psi | higher; owner's manual |
Read them on tyres that have rested a few hours. A ride across town warms the rubber and pushes the gauge up 2 or 3 psi.
Riding two up on a 10 inch rear tyre
Mothers dropping children at school, college students sharing a ride, a parent with a bag of vegetables on the floor: the Pep carries more than it looks built for. When the rear tyre is left at 29 psi with two adults, it squats, the sidewall flexes on every speed breaker and the rim can strike a sharp pothole edge. Add air to the rear before a two up ride, to the figure in your manual, and let it back down when you ride alone again. The front stays at 24.

Digital pumps at fuel stations usually show psi, but some older dial machines show bar or kg/cm. For any other value, use the tyre pressure converter.
Getting Scooty Pep tyre pressure right at the pump
- Put the Pep on its centre stand; both wheels can then turn freely.
- The 10 inch wheels tuck the valve beside the brake drum, so rotate each wheel until its valve is at the top.
- Push the nozzle straight on. A crooked nozzle lets air hiss out and gives a false low reading.
- Key in 24 when doing the front, then 29 at the rear.
- Fit the caps. Dust in a small scooter valve is a common slow leak.
Pump gauges drift. A small gauge living in the Pep's under seat box is cheap insurance; read about tyre pressure gauge types.
Low and high pressure on a light scooter
Below 20 psi at the rear, the Pep feels heavy to steer, drinks more fuel and wears both tyre edges. Low pressure in a tubeless tyre also lets the bead move on the rim, which can start a slow leak. Going the other way, filling 35 or 40 because the sidewall shows a higher maximum makes the small scooter skate on wet tiles at a parking ramp and bounce over ridges. The sidewall maximum marks a limit, never a target.
Monsoon puddles, summer heat and weekend trips
In the monsoon, keep exact pressures. An under filled small front tyre slips easily on zebra crossing paint and manhole lids. In May heat, check early in the morning so the reading is honest. Before a long weekend ride on a highway, check both tyres and look for nails picked up in the city; small tyres collect them. If the Pep keeps losing air week after week, a puncture shop can trace the leak with a tub of soapy water.

Questions owners ask
What air pressure suits a Scooty Pep Plus?
Solo, 24 psi for the nose wheel, 29 psi for the driven wheel, both measured cold. Carrying a pillion calls for a higher rear figure, listed in your manual.
Why does the Pep rear tyre take more psi?
Its motor and much of your body weight press down on the back wheel. Both tyres are the same size, but the rear carries far more load.
Scooty Pep Plus tyre pressure with a pillion?
Keep 24 psi in front. Raise the rear; since printed figures disagree, follow your own manual.
Is 30 psi in both Pep tyres okay?
The rear would be near enough, but 30 in the front is too hard and makes the scooter twitchy on rough roads. Keep the front at 24.
Does a girl or a light rider need less air?
No. The scooter's own weight is a big part of the load, so use the same 24 and 29 for any solo rider.
How often should I check Pep tyre pressure?
Weekly if you ride daily. Small 10 inch tyres hold little air, so a 2 or 3 psi loss changes the ride noticeably.
