Haven't heard of M-Sport, yet? Granted, it's Euro, so we don't get it on this side of the big pond, lol. It also doesn't help with a lift, since most people lower these vans. Who knew that a cargo van could look so hot? haha - http://www.m-sport.co.uk/m-sport-news/dovenby-hall/revealing-the-m-sport-ford-connect

On the topic of larger A/T tires, I'm running General Grabber AT2 215/65R16 on my stock steel wheels. I haven't had any rubbing issues, the tires give me about 1/2" more ground clearance which is basically nothing. They do fling gravel like an SOB (I have gravel driveway and live in a rural town that has gravel roads except for the main roads being paved) and of course the speedo is off a bit because of the taller profile - 66 indicated is actually 70MPH road speed.
