The Ntorq 150 tyre pressure published for riding alone reads 24 psi on the nose and 32 psi behind, taken cold. Carry someone behind you and the back figure alone climbs, to 36 psi, while the nose holds steady.
These figures appear in published spec listings; a general chart from TVS for the Ntorq name shows 24 psi up front with 34 to 36 psi behind, so let your owner's manual act as the final word for your scooter. Either way, never fill to the maximum number moulded on the tyre.

| Load | Front | Rear |
|---|---|---|
| Rider only | 24 psi | 32 psi |
| Rider and pillion | 24 psi | 36 psi |
Nose pressure never moves because steering geometry and the front disc work best at one pressure. The back changes because a second adult loads the rear shock and tyre far more than the nose. Values assume cold tyres on the stock 100/80-12 front and 110/80-12 rear.
What cold means for a scooter
Cold here describes tyres measured after an overnight rest or a long lunch break parked in shade, or after only a short slow hop from home. After a hot afternoon commute the air inside expands and the gauge can read 2 to 4 psi high. Do not let that air out; recheck the next morning instead. If you must fill on the way, add 2 psi over target and correct it later when cool.
Converting these figures to bar and kPa
| psi | bar | kPa |
|---|---|---|
| 24 | 1.65 | 165 |
| 32 | 2.21 | 221 |
| 36 | 2.48 | 248 |
Certain digital air towers show units other than psi. Use our psi to bar converter for any other value, and set the machine before you press the nozzle on.
Topping up the Ntorq 150 at a fuel station
- Put the Ntorq up on the main stand over level paving, ignition off.
- Pocket the valve caps; dropped ones vanish into gutters.
- Key in 24 for the front, then press the air head firmly and straight until the tower signals done.
- Dial 32 for the back, or 36 when a passenger rides along.
- Cross check with a gauge you own, since forecourt meters wander.
- Screw the caps back, because grit on the core is a classic source of creeping air loss.
Our guide to reading a tyre gauge covers the details.
Wrong air and how the Ntorq 150 reacts
Soft tyres make the Ntorq 150 steer like a loaded trolley at parking speeds, scrub both shoulders, cost mileage and let the 12 inch rim strike crater edges hard enough to crack an alloy. Too much air leaves a smaller footprint, so the back hops across grooved concrete and the ABS triggers earlier on wet paint lines. A sporty 150 cc scooter accelerates and brakes hard, which makes the right pressure a safety matter, not just comfort.
Monsoon, highway and long ride notes
In heavy rain keep pressure exactly at spec; lowering it does not add grip on a scooter and makes aquaplaning on standing water more likely. Before an expressway run with a passenger, set the back to 36 psi at home and recheck when you pause for chai. Slow leaks are common after potholes in the rains, so a weekly check catches a dent in the rim or a nail early.
Ntorq 150 tyre pressure versus the 125
Owners who move from the 125 should not assume identical numbers. Our Ntorq 125 pressure page lists that model's own manual figures. Tyre sizes match between the two, as shown under Ntorq 150 tyres, but engines, weights and recommended air differ. For scooters generally, see scooty tyre pressure and our main tyre pressure guide.
Questions owners ask
TVS Ntorq 150 tyre pressure for riding alone?
Spec listings show 24 psi for the nose and 32 psi for the back tyre, read cold. Your owner's manual holds the maker's final figure.
Two up, what changes?
Only the back tyre: take it to 36 psi, leaving 24 psi in front. Return it to 32 psi once you are solo.
Is 30 psi in both tyres okay?
No. That over fills the front by 6 psi, which hurts grip and braking, and leaves the rear slightly soft for two up riding.
Does the TFT version need different air?
No. Standard and TFT share wheels, tyres and weight class, so the 24 and 32 psi solo figures apply to both.
Weekly or daily checks?
Weekly with a gauge, plus every time you plan a long run or a passenger.
Converted to bar, how much is the solo rear figure?
Thirty two psi works out near 2.21 bar; a metric dial would read 221 kPa.
