Subject: Warning! Audi and Mercedes wheels are dangerous! (long)
Content-Type: text/plain; charset="us-ascii"
Dear Volks,
I am surprised that the engineers among us haven't yet chimed in on the
issue of using the proper offset wheels with our precious Vanagons. Use of
improper offset wheels causes premature wheel bearing failure and delivers
poor handling -- the latter especially important in a vehicle that needs
all the handling help it can get!
There are many posts in the archive extolling the virtues of Mercedes and
Audi rims. Most notable among them is the low cost of these wheels. Yet,
neither Audi nor Mercedes wheels have anywhere near the proper offset (in
spite of the fact that the bolt holes are the same as the Vanagon). The
diagram below shows what happens to the track width of your Vanagon when a
larger offset wheel is used -- the track width gets SMALLER (and handling
suffers). Note the significant difference in track width between the 6"
Audi/Mercedes rims and a 7" rim with proper offset -- the latter delivering
over 2 1/2" greater track width!!!!
Besides the unique/unusual offset, Vanagon wheels are notoriously too small
in width for today's aggressive tires. Most Vanagons came with 14"x5.5"
steel wheels. The 5.5" width relegated us to smallish tire sizes. For those
of us who wished to put "bigger" tires on our vans the only other "stock"
option was the 14"x6" alloy rims. These alloy rims allowed tire sizes up to
215mm (8.5") in tread width. For larger size tires a 7" rim is required!!!!
NOTE: While a 6" rim will work for 215mm (8.5") tires a 7" rim is
RECOMMENDED due to the better shape of the sidewall, which delivers better
handling.
AND NEVER USE 5.5" RIMS FOR 215mm (8.5") TIRES -- IT IS DANGEROUS!!!!!
Due to the serious consequences of using Audi/Mercedes wheels, I hope that
all Vanagon listees will stop promoting the myth that there is a cheap
solution to our dilemma. For serious tires (whether off-road or street), a
7" rim with 23mm offset is the only way to go. Both Winkler and Projectwo
sell such wheels in 14", 15", and 16" diameters. Unfortunately, they are
expensive. But then, so are our Vanagons.
