I'm taking a trip to Chile and Argentina and am planning to buy a small van to get around and live in. I've been looking at Partners since they seem to offer enough space while still being economical to run. One of my concerns is the relatively low ground clearance and small city oriented tires since many of the roads, especially further south, are unpaved and can be a quite rough. I was wondering how feasible it would be to fit all terrain tires? I've had good experiences with General Grabber AT2 tires but the smallest size they come in for 15" wheels is 205/75/15 (27.1" overall diameter). I think the largest stock tires that come fitted are 215/55/16 which is 25.3" overall. Anyone have any experience fitting larger tires?
