The XL 100 tyre size is 2.50-16 for both wheels, on every variant from the kick start Heavy Duty to the HD Alloy. The spoke wheel versions run tube type tyres; the HD Alloy is the first XL100 with tubeless tyres.
This moped works hard. It carries milk cans, gas cylinders, vegetable sacks and a second rider, often on broken village roads. That makes the right tyre, the right ply rating and the right rear pressure more important here than on most two wheelers. Below you will find all three, along with tips for making a set last.

TVS XL 100 tyre size by variant
| Variant | Front | Rear | Wheel |
|---|---|---|---|
| Heavy Duty (kick start) | 2.50-16 41L | 2.50-16 41L | 16 inch spoke, tube type |
| Heavy Duty i-Touchstart | 2.50-16 41L | 2.50-16 41L | 16 inch spoke, tube type |
| Comfort i-Touchstart | 2.50-16 41L | 2.50-16 41L | 16 inch spoke, tube type |
| Win Edition | 2.50-16 41L | 2.50-16 41L | 16 inch spoke, tube type |
| HD Alloy | 2.50-16 41L | 2.50-16 | 16 inch alloy, tubeless |
The size never changes, so a front tyre and a rear tyre are the same part. That is handy: one spare tyre in the shop or at home covers both ends. What changes is whether you need a tube. Air seeps out around spoke nipples, so even a tubeless labelled tyre needs a tube on these wheels.
What 2.50-16 means on a moped
This is an older style size written in inches. The 2.50 is the section width, about 64 mm. The 16 tells you the rim measures sixteen inches. No profile figure appears because these narrow tyres are roughly as tall in the wall as they are wide, which puts the whole tyre at about 533 mm across. The dash means bias ply build, not radial.
The large 16 inch wheel is the reason the XL rolls over potholes and kachcha tracks more easily than a scooter with 10 or 12 inch wheels. The narrow tread keeps steering light even with a heavy load on the carrier.
Ply rating and load index
The factory tyres are 6 ply with a 41L marking. Load index 41 means 145 kg per tyre, and L means a top rated speed of 120 km/h, a speed this moped never approaches. The 6 ply build is stiffer than the 4 ply tyres often sold for light mopeds, and it matters when the rear carries a cylinder or sacks. Ask for 6 ply when you replace. Our load index chart lists other values.
Air pressure solo and with load
| Load | Front | Rear |
|---|---|---|
| Rider only | 25 psi | 35 psi |
| Rider with pillion or goods | 25 psi | 40 psi |
TVS publishes these cold values itself. With a second rider or a sack aboard, TVS wants 40 psi at the back, since almost all the weight sits over the back wheel. Carrying a cylinder at 35 psi squashes the rear wall, warms the tube and invites pinch punctures. Do your check at dawn, before the first trip. See psi to bar if the pump shows bar.
Tubes, rim tape and the HD Alloy
On spoke wheels you must use a tube. Ask for a 2.50-16 tube with a strong valve, and fit a rim tape that covers the spoke nipples, or they will chafe through it. On the HD Alloy, the tubeless tyre seals against the rim, so a nail leaves only a slow leak that a puncture wallah can plug with the wheel still in place. Read tubeless versus tube tyres and tyre tube for more.
When to change XL100 tyres
- The rear tread wears two to three times faster than the front on a moped used for goods. Swap the rear when the grooves fade to the wear bars.
- Cracks between the tread blocks mean old rubber, common on mopeds that sit outside in the sun.
- A bulge on the wall means a broken cord inside. Push the moped, or ride it in first gear at a crawl, until a puncture repairer can examine it.
- Flats that keep returning to one spot usually mean a spoke tip poking through worn rim tape.
Other XL100 and bike tyre pages
The XL 100 alloy wheels page explains which version has alloys and whether a spoke model can switch. Families who also run a 100 cc motorcycle can compare with the Splendor, and two wheelers of every kind are gathered on the bike tyre size index. Keep the XL's 6 ply rating in mind whichever shop you visit.
Questions owners ask
What tyre does a TVS XL 100 need?
Every variant takes 2.50-16 on both wheels. The factory tyre is 6 ply with a 41L load and speed marking.
Are the front and rear XL100 tyres the same?
Yes, the size is identical. You can fit the same tyre at either end, though the rear wears faster and is usually replaced first.
XL100 air: how many psi front and back?
Fill 25 psi in front. At the rear, fill 35 psi riding alone and 40 psi with a pillion or goods. Check cold, before riding.
Is the XL100 tyre tubeless?
Only on the HD Alloy. The Heavy Duty, Comfort and Win Edition run wire wheels carrying tubed tyres.
Would a fatter tyre suit the XL100?
Skip it. The mudguards and fork have little room, and the maker fits only 2.50-16. Stick to that size and the 6 ply rating.
Why does my XL100 rear tyre puncture so often?
Running soft at the back while loaded pinches the tube. Hold 40 psi with cargo, and inspect the tape covering the spoke nipples.
