I ran Michelins on my last Range Rover, they wear well, they grip well, and they don't go out of shape when they get a bit of age. I got 50,000 miles out of the last set and I don't drive it particularly gently! Guess what I replaced them with...
Hankooks are fitted as original equipment on quite a few Transits and I haven't heard a bad report about them.
I've finally persuaded to get my mother to replace her Pirellis with Michelins on her Volvo 960 3 litre 24valve auto, and she say's it's like a different car. The Pirellis gave a hard ride and followed every rut in the road surface. (I wouldn't fit them on a wheelbarrow!)
I would suggest that cheap isn't necessarily good value, particularly if you're keeping the van for a while. Good Year and Bridgestone aren't a bad tyre but I would recommend Michelin every time.
p.s. good advice about ringing round first too!
