now have about one year on 15"audi turbo wheels and pirelli scorpion
215/75-15's on the syncro and thought i would inject some real world
experience rather than supposition and theory on the effects of
oversize tires and wheels.
advantages: (1) the van has a better ride then it did w/ the stock
tires [can't honestly say that this is the size advantage other than
the higher sidewall being slightly more compliant]; (2) more ground
clearance for the syncro--about 2" higher than it was before; (3)
lower rpm at highway speed w/  no real perceivable difference in power
[it has always been a dog on 5 mile hills!]; (4) greater choice of off
road tires in 15"[ i paid $52 each for the pirellis]; (5) no change in
braking performance or handling that can be detected by anything other
than a g meter.
disadvantages: (1) spare tire size may be a problem for some; (2)
initial acceleration [0 - 5mph ] is slightly slower; (3) the larger
tires do not hold a wheel balance as long.

still the best thing that i have done to the syncro.....

cheers
