Mongo just lost 60.4lbs!

I received my new wheels this evening and couldn't resist mounting them after dinner. As a guy who values the reduction of unsprung weight, I had to order a set of lighter wheels and non-RFT tires to both improve performance and to reduce the ride harshness. With any luck, the mpgs will benefit a bit too.

BMW 300M & Bridgestone Deuler HP
Front Drvr: 80.4lbs
Front Psgr: 80.0lbs
Rear Drvr: 88.4lbs
Rear Psgr: 89.0lbs

O.Z. Superturismo Dakar & Continental DWS
Front Drvr: 63.6lbs
Front Psgr: 63.6lbs
Rear Drvr: 75.0lbs
Rear Psgr: 75.2lbs

From a weight point of view, I could have saved another 23lbs if I went with 285/40R20's on all four corners. Now, only if I was patient enough to special order a set of custom forged wheels, I could have trimmed even more weight...

The only difference between the pics below was I used a flash in the second one. The sun had set, yet the was plenty of daylight for a slow shutter shot, but the flash pic made it look like it was night time.
