Hello

wheels)
exchange the cost is $550 for the set including caps plus shipping and
handling $70-$80 plus refundable core charge $850 set .
They are triple plated ,which means they have a copper then nickel then
chrome layer and come with a one year warranty against peeling and
blistering . We DO NO RECOMMEND driving on them in the SNOW or on SALTED
roads this will cause the chrome to pit in the slots and is NOT COVERED by
the warranty. We use the highest quality chrome available.

Please spin your exchange wheels before shipping them back for a refund on
your core deposit. A repair fee will be charged if the exchange wheels are
bent or slightly damaged .Used chrome wheels are not acceptable as exchange
core wheels.
