I went overboard, grabbing specs for wheels and tires. Going from the 17s to these 18s I lost weight in the rear and gained less than 1 lbs at the front.
This combo should weigh around 42.2 lbs front and 45.3 lbs rear. These are based on actual rim weights and the manufacturer weight for tires.... so who knows!?!

Your weights are probably pretty close. I weighed my 17 inch and 18 inch sets of wheels and tires when I changed them over last weekend.
17 inch Boxster S II wheels, front with 205/50 Michelin Pilot Sport N3 tire with 12,120 miles, 39.0 lbs. Rear with 255/40 same tire and miles 44.8 lbs.
18 inch Boxster Lt. Alloy Carrera wheels, front with 225/40 Michelin Pilot Sport 4S tires with 8,850 miles, 41.6 lbs. Rears with 265/35 same tires and miles 47.0 lbs.
Hard to say how treadwear affects weight, all my tires have plenty of tread left though.
