I just installed, at last, some new wheels and tires. I dithered for so long and ended up with a compromise. The wheels are Mercedes alloys,15″ x 7″, ET of 25. The tires are Yokohama Geolander ATS 215/70-15.
The offset is a bit lower than perfect, the wheels stick out a little more but that gives a tad more clearance on the suspension side and the sliding door clears tire by a good 3/8″.
Simon left his van with me while he is on a trip to an un-namable place so I had a chance to do a visual comparison” his wheels are 15″, ET 30, and I think 6.5″ wide, South African carats. The tires are nokian WRC, 205/70-15.
I have only riven a short distance on my new tires but I lie, what I feel so far. Smoother over bumps, little tire noise. They change the feel of the van in a very good way.
Here is quick vid of the two vans, Simon’s van is the high top.
