When does a retread make sense?
Which axle can take a retreaded truck tire, when does it save money and what to watch out for?
What is a retread?
A retread is a worn tire whose sound casing gets a new tread layer. A well-maintained truck casing can be retreaded once or twice, at a clear cost saving compared with a new tire.
Where it makes sense
- Trailer and drive axles: the positions where retreads are used most.
- Regular, medium-distance work: city distribution, construction sites, fixed routes.
- Good casings: premium brand, no sidewall cuts, no heavy ageing.
Where it does not
- Steer axle: the most critical position; in many countries retreads are not allowed on the front axle of buses and coaches. Check local rules.
- Sidewall damage, large repairs or very old casings.
- Vehicles running constantly at high speed and maximum load.
Things to check
- Use a certified retreader and ask how casings are inspected.
- When a retread and a new tire run as duals, check their diameters with the dual tire match tool.
- Check pressure regularly; under-inflation is the biggest enemy of retreads.
Pulling tires before the tread is completely gone (about 3–4 mm left) protects the casing and improves the chance of a retread.
