When I test drove the PM a month & a half ago, I checked the tires to see what they were offering. They had Continental Vanco 4 Season tires. I've read some not so great reviews on them complaining of premature wear and a pretty noisy tire. I'm not super up to speed on what tires are/aren't good. Any thoughts?
Having owned 2 Sprinters with the Conti Vancos, all I can recommend is when you do your deal, get those tires OFF your vehicle. Try to get the dealer to swap out with the Michelins recommended above.
All the RVers we know that have the Sprinter with the Contis, more than a dozen of them, were lucky to get 30k miles out of them, and had a lot of balancing issues over the short life of their tires, (we are one of those).
Most all replaced with the Michelins and rave about them as being so much quieter and longer wearing
