Symptoms
Slow leaks at the bead ring, old tyres, mismatched sizes after a replacement.
The fix, step by step
- Deflate, remove the ring bolts in sequence, inspect the inner bead and O-ring, then refit with the bolts torqued evenly.
- Owners have fitted both 37×12.50R18 and 38×13.50R18 tyres.
- Recode the size and recalibrate the tyre-pressure gauges.
