17\" Wheels and MTR ??? Does anybody know where I can find STEEL 17" rims. I have been serching the web and so far nothing. I'm tring to figure out how much it's going to cost me to step up to 37" MTR's on Donna's K5. The tires are about $30 more each for the 17" wheel compared to a 15" but the 17" will allow more backspacing without grinding the calipers. Also looking for the best price on MTR's. Tirerack has good prices and I checked locally and it will run $190 each mounted and balanced for the 37x12.5x15's but I think that price is a little high.
