Some of us are always in search of lighter wheels, and make a big deal over a difference of 2 or 3 lbs between different wheels.

Well, ever since I got Yokohama ES100s to replace a pair of Pirelli PZero Rossos, I had a suspicious feeling that the new tires weighed more. I just weighed em and confirmed this.

Alpina Softline 18x8.5+PZero Rosso 235/40/18 40.8lbs (new)
Alpina Softline 18x8.5+ES 100 235/40/18 43lbs (~5000mi but don't look very worn)

Now, I never weighed my fronts when new, but just as another reference point:
Alpina Softline 18x8+PZero Rosso 235/40/18 38lbs (~17000mi, pretty worn out)

The difference in weight between the 8.5 and 8in wide Alpinas should be about 1lb, so the tire has lost almost 2lb over its life.

Also, from a previous measurement, BMW Type 44 17x8+ContiSportContact 225/45/17 47.5lbs (my stock unused spare)

That's pretty darn light! I weighed e46 m3 wheels(fronts) with stock pilots, and they were just at the 50lb mark. :yikes: When I was shipping them out, they weighed in at 55.5 lbs per box. So yea, stock wheels are pretty heavy.

And that is another reason why comp tires should be shaved. Smaller diamater (better gearing), lighter, and the less chunking. But even tires that don't tend to chunk benefit from shaving.

This sounds about right. I measured my Type 44 17x8+ContiSportContact 225/45/17 at 49 lbs. It's amazing how light those Alpinas are!!

I need to weigh my wheels at some point.

The car feels a LOT zippier with the superleggeras on.

Yeah, but we want to find out exactly how much. ;)

I need to get a scale. :p

Does anyone know how much 225/45-17 S-03s weigh?

What about Style 73s?

I'll try to weigh em, just in case anyone cares what the M72's w/Potenza RE040 weigh. I don't think they're very light, not from what my back says carrying them in....

IIRC the stock 19s are forged which should help in the weight department. I know SSR GT3s with stock-sized 19s (I think these were S-03s) were over 50lbs.

within the same brand/model/size combinations; the larger the diameter the heavier the combination gets.
