Why not the tier 5 a salesman was telling us last week that they're gonna be even better now
He mentioned axles and hub but the wheel thing never crossed my mind . I know what you mean with the teething problem thing we've been lucky with JD apart from an early 20 series and have avoided the first of a new range since for that very reasonTier 5 has bigger axles and hubs which means our wide tyres wouldn’t fit. We’ve got a pair of 42s and wanted them interchangeable.
Also the teething problems of the Tier 4 should be nearly sorted, the Tier 5s will probably have some new ones.
