Is the $2700 rims and tires the OEM 18" rims and Bridgestone Blizzak WS-50 winter tires? If the tires are around $520 ($130 x 4), then those rims are $545 each :o That's a little too much for dedicated snow tire rims. If that were the case, then I'd look for aftermarket 18" wheels close to OEM spec: 18" x 7", +35 offset, 5 bolts 114.3mm (4.5in).
