We have a 1997 Dodge Caravan SE, it's a work van and pretty beat up, we needed a set of tires so I ordered a cheap set from Jack Williams. I had the wife take it in while I was at work and when I got home I noticed they put a nice brand new set of Michelin Defender's on it. They haven't said anything yet, but the tires are bigger, our van size is 215/65/15, the Michelin's are 215/70/15, I was wondering how this would affect the van? I had her get in it and turn the wheel all the way and there is still a good 4-4 1/2 inches of room between the tire and the inside of the fender well.

 

It should be fine, the tires you have will make your van go about 2 mph faster than it used to at 65mph.
