Joyor S10-S-Z · Tyres & wheels
Tyre is worn or cracked
When the tread knobs are nearly flat or the rubber cracks, grip drops fast, especially in the wet.
Is this your problem?
- Knobs on the tread are low or gone in the middle
- Small cracks on the sidewall
- Sliding on wet roads
Likely causes
Compare the middle of the tread with the edges. Look for cords showing through anywhere: that tyre must be replaced now.

Step by step
Tap a step when it’s done to keep your place.
- Get the right tyre
Same size as yours: 10 × 3 (255 × 80 / 80/65-6), tubed, off-road tread. Joyor sells one listed for this model.
- Remove the wheel
Exactly as in the flat-tyre guide, steps 1–5.
- Fit the new tyre with a new tube
A new tyre is stiffer than the old one. Warm it in the sun first, and use soapy water on the bead.
- Seat, inflate, refit and test
As in the flat-tyre guide, steps 9–11.
Stay safe
- New tyres can be slippery for the first few km.
When to take it to a shop
If you cannot get the new tyre on; it can be really stiff.
