Well, I went to the Michelin site & Tire Rack site and found the reported weight for my Pilot Alpin 3's that I have mounted to my OEM rims. Then I went into the basement armed with my handheld suitcase scale (can't risk going over 50lbs these days). Lo and behold, here's what I found:

Front Tire & Rim Weight: 49.7 lbs (measured)
Front Tire Weight: 21.5 lbs (per Michelin web specs & Tire Rack)
Front Rim Weight: 28.2 lbs (calculated)

Rear Tire & Rim Weight: 53.0 lbs (measured)
Rear Tire Weight: 23.4 lbs (per Michelin web specs & Tire Rack)
Rear Rim Weight: 29.6 lbs (calculated)

The reported-on-forum rim weights (24.75, 25.88) may not include the TPMS, balancing weights and center cap but that sure doesn't make up the 4 lbs difference between what I've observed. Hmmm.... Too bad I didn't weigh the Sportlines & Conti's before I put them on the car. Oh well.

Here are some more pics. Some outdoors from yesterday, some indoors today.
