what tires would you recommend for a 2006 e350. I was looking at the Bridgestone Potenza RE960 AS Pole Position since they seem to have good reviews but what would you recommend?

 

Michelin Primacy. Either the Pilot or standard touring. You can't go wrong with Michelin.

 

Ditto. can't go wrong with Michelins,
I've been running Pilot PS2's, 235/40/18 summers and 215/55/16 Arctic Alpin PA2 winters on my '98 E320 4matic wagon for 2 years. Sticky and safe. 75% left on all, no problems, awesome tires. Loved all my Bridgestones, too, though. Definately my 2nd choice, and usually quite a bit cheaper. Bridgestone Blizzaks may be a better winter tire, but I think the PS2 is a better summer.
