Tyres wear for a reason. Before replacing a set, look at the pattern and the pressures. The new tyre will wear the same way if the cause is still there.
Check pressure and load
Under-inflation causes edge wear and heat; over-inflation wears the centre. Check cold pressures for the load and recheck with a gauge you trust.
A slow leak can mimic a pressure problem. Check the valve and the bead.
Look at the pattern
Cupping on the front often points to suspension, balance or braking habits. A squared-off rear centre is common on commuting bikes; it is not a fault if the use matches the wear.
One-sided wear suggests alignment, a bent fork or a rider who leans consistently. Check the rear-wheel alignment and the fork.
Check suspension and bearings
Worn fork bushes, a weak shock or a bad wheel bearing can cause uneven contact. Check for play and damping condition.
A steering-head bearing that is too tight or notchy can also affect wear.
Replace as a pair when sensible
Matching age and type helps the bike feel consistent. If one tyre is old or mismatched, replace both when the budget allows.
Check the date code. Rubber hardens before the tread disappears.
Checklist
- Cold tyre pressures for the load.
- Wear pattern: centre, edges, cupping, one side.
- Wheel balance and runout.
- Fork alignment and bearing play.
- Suspension damping and sag.
- Tyre age and date code.
- Brake drag and wheel bearing condition.
Questions
Why is my front tyre cupping?
Cupping can come from suspension, balance, pressure or braking. Check the simple items before replacing the tyre.
Can I replace only the rear?
Sometimes, but matching age and type helps. If the front is old or worn, replace both.
How old is too old for a tyre?
Rubber hardens with age. Check the date code and inspect for cracks, even if the tread looks good.
