thats the van i got, phone up tyre companys and tell them what you use your van for and how much payload you use and theyll tell you to get Michelin Agilis as these are used when a van is used with a full payload
Usually with tyres, you pay a higher amount for softer rubber (I think) which improves road holding but which also means that they don't last as long.
Are you paying the higher rate for better roadholding/less longevity or are you paying the higher rate because the tyres last a lot longer?
BTW. Not totally sure that what I've written is factual as it's anecdotal.
I'm happy to pay a lot more for tyres if I get a much higher lifespan from them but not for better roadholding if that means a shorter tyre life. Before they all start jumping on me, I want to say that I do take things very gently with my driving - especially when I have a load of water on board.
