Rotational weight reduction...

Michelin P.S.S. are 5 lbs lighter each compared with stock,RE050A.??I think it is very good.

I found this excel spreadsheet to be helpful and informative regarding the effects of rotational mass -- check it out

Check out the weights for Toyo TS1 (or whatever the comparable tire is now). Very light -- not the grippiest, so that's a compromise, but far lighter than similar quality tires.

That sounds like a lot just for tires...

I explained this to DEpointfive0 a week ago. Tire weight variance is pretty significant depending on tire and what you are looking for. Some people go lighter wheels to run wider tires gaining the weight they just shaved from lighter wheels.In the end, you can't go everything light. you just need a good compromise of the 2. I saved about 6lbs per corner from wheel weight just to add back about 4lbs per tire for a wider setup. Traction on its own is worth it even if I didn't lose much weight. Just like I'd still rather put a set of RE-11s on even though they are 3 lbs heavier per corner then the P.S.S. but track wise the RE-11's way outperform the super sports. Road wise, the michelins win.

Yeah, he did, it was ridiculous, there was an 8 POUND difference in the 2 tires I was looking at... I almost cried

I know I could probably google it, but what's a good website to find out specific tire weights and other info?

Manufacturer website.

I usually start looking for recommendations from Grassroots motorsports or peruse tirerack reviews to narrow it down to a list of sticky tires, then I look at price, weight, wear rating (usually lower for stickier tires), wet and dry ratings, etc.
