Adrian,

Unless you are willing to change the ratio of the final drives, stick with
the stock wheels and get some C or D rated rubber for them.  You will be
happier and your properly geared van will be much more driveable.

PS: I once replaced an automatic with a hand-shaker in a car.  Being in a
rush to get it on the road, I decided to leave the original rearend in place.
 Beforehand, I did some calculations and found that in top gear the auto
rearend would drop the revs a couple of hundred RPM's, so I reasoned that
this setup would be like a quasi-overdrive.  It was.  But, around town the
car never saw fourth gear and I was smoking the new clutch every time I had
to pull away on even the slightest grade.  After about a week of this, I
installed the correctly geared rearend ASAP.
