I am finding it difficult getting details and costs for a (if there are such things) tyre maintenance and replacement contract. Am I right in thinking that its possible to pay a set monthly price to have emergency cover for this? Also, would anyone know the approximate cost of regular tyres on say a Actros trac unit. cheers
i suggest you ask this in the owners forum
Agree with the suggestion that you should post in the OD forum. I’m pretty sure that any kind of maintenance contract is available; it just depends on what you’re willing to pay 
A bus company I know has a rental contract for tyres - they don’t actually own any of them, they just pay a few pence per mile travelled, and everything is handled by the tyre company.
