Riptide

Numbers vary on the internet but when I went digging a month or so back the weight for the satin silver 17x8 was 23 pounds.

The stock 235/55/17 pirelli is something I was unable to find. However my guess is that it's close to 28 pounds. I base this off of researching a TON of different tires including some in that size.

Maybe someone can verify or correct this. I have my summer wheels/tires off the car, so just for giggles I went down and weighed them. They are 20" foose nitrous with nitto 555's, 275/35 20. I hope my scale is off, cuz it says each wheel/tire weighs 65 lbs. If Rip's numbers are right thats 14 lbs a wheel and 56 total.

May have some Foose's up for sale next year

I've got boat anchors. 18x10 deep dish. 26 pounds each. And with a 32 pound tire I've got 58 pounds on each wheel. w00t!

I pulled mine 19x8.5 stock wheels off monday, and wheel and tire was at least 55 to 60. tires are diff. more than wheels.

I'm pretty sure that's where you'd start any derivation of a MOI formula from scratch. The approach is to take the effect of every tiny little piece of mass (m) at its own radius (r), and add it all up. "Adding it all up" is the same thing as "integral calculus", but a lot less scary-sounding.


The ice skater is the classic textbook illustration. For those of us who finished school before break dancing came about, anyway.

Try this experiment. Take a can of Budweiser and a oilcan size Fosters beer. Lay them on their sides. Roll them both at the same exact speed for one complete revolution.

Which one went farther on one revolution? The Fosters.

Now, drink both beers. Buy the 20s and put a set of 4.10 gears in and be done with it.

this example is useless. you are talking about 2 different diameters.

bluovalguy

I think that is what he meant by oilcan size of fosters.

And if not, drinking beer is never useless

kentompkins

We could always use a Bud and a Fosters. It was joke, Matt.

I've been sitting back looking at all responses and there are obviously a bunch of different opinions, but I guess logic would dictate that 20"s will slow you down and I have to admit I was impressed with Norm's answer (you seem to know your sh..). Kentompkins said something interesting that got my interest, "Buy the 20"s and install a set of 4:10's and be done with it" which is what I'm actually doing. My car came originaly with 3:55's and I installed a set of 3:73's last winter but going with 4:10's now, but I'm still undecided about the 20"s. I must say my stock 18"s look great and will probably just put a little more meat on the rear and leave well enough alone.

Thanks for all your responses Guys.
