I really like the Pretorias though - does anyone know the official weight of the 18" version? I may have to take them off and weigh them myself, but deducting the stock Bridgestone weight.
I weighed the factory 18" Pretorias with the stock Bridgestones, then the Bridgestones only, with about 2000 miles on them after I had Michelin Pilot Sport 4 S mounted on my Pretorias.
Weight of tire and wheel: 45.4 lbs
Weight of tire: 22 lbs
While Bridgestone lists the weight at 25 lbs, Tirerack's measurement of 22 lbs was accurate for me. Maybe it it weighs more than 25 lbs, Bridgestone considers it out of spec.
That gives us a weight of just under 23.5 lbs for the OE 18x7.5" Pretoria, maybe 23.25 subtracting the weight of the stem and wheel weights. IMO, that's fairly typical (and maybe even on the light side) for a low pressure cast OEM wheel that's generally going to err on the side of durability. My 18x7" Gen 1 Mazdaspeed3 wheels were 24 lbs, the Gen 2 18x7.5" were 25 lbs each.
