I am in need of new set of 235/55/17 103 tyres. Currently using Michelin Primacy 3 tyres, but they are chunking badly on the fronts after +-23000 km. IMHO Primacy 3 tyres are not suitable for front wheel drive vehicles of this weight, the compound is not up to the task it would seem. Would like some recommendations on tyres that are fit for purpose on the bus.

When I bought the vehicle it had Pirellis on with a 99 load index and they seemed more suited to the task appart from being the wrong load rating.
