Your going to have to be more specific, there are at least Four different types I know of myself:

1. ES Momentum 5 spoke wheels, semi chromish
2. SE "hazard" symbol wheels
3. Numerous Steelies and different hubcap combos
4. The first sset of split spoke 5 star wheels, 98-00 maybe?

It depends also on how much air is in the tire, 27-40 PSI?

Ok, the ES Momentum's then, which is what was stock on my car, with lets say 35 psi in each. I'm just curious how much weight I've actually gained with the 20's. (total shipping weight for all 4 wheels mounted with tires and about 40 psi in each was 296 lbs...or 74lbs per wheel/tire)

After I put the 300lbs of stereo/video equip in this spring, I'll be really be ridin' low and heavy! LOL

Holly smokes that's heavy. Stocks are a lot lighter than that I can tell you.

My RS-A tires were 29 lbs each, and I'm guessing the 16" "police safety rims" are about 25 - 30 lbs apiece.

Don't forget with a larger rim the weight is concentrated more towards the outside, which increases the rotational inertia even further (i.e., a 74lbs 15" will be faster than a 74lbs 20")

300lbs of equipment? What are you putting a DJ booth in that thing?

LOL! Lets just say its gonna be bigger and better than what I had in it before the burglary. (just guestimating the weight) Highly exaggerated I'm sure, although the subs WILL be heavy...

whoo better let some psi out so they will weight less! :grinno:

umm who wants wheels? I still have my stock momentum w/ no tires on them.........they might weigh 20lbs tops

Well yeah, I know they're lighter. I was wondering by how much though. Curious as to how much weight I've actually gained...So, you're saying mine are about 13-19 lbs heavier.

The weight being concentrated toward the outside of the rim ultimately depends on the design of the wheel itself, wether its a 16", 20", or whatever.
In my case, yes, I have more "meat" towards the outside. The debate over physics pretty much goes like this, true, rotational inertia takes a hit on the larger wheels, taking away from bottom end. But a few other laws of physics are gained such as momentum and centrifugal force, thus adding to top end. Its just a matter of preference. A guy with the same motor might beat me in a standing 1/4 mile or light to light with 16"s, but on the highway things change. I would say I could get from 45 to 65, or 65 to 85 ALOT faster...

In short, it takes more horseys to turn a heavier wheel...period. As for the other side, here's one analogy: Turn off your computer and take the side panel off. Now spin the CPU fan with your finger and count how many revolutions it makes. Now reach above your head and spin the ceiling fan. Took a little more muscle right? But how many revolutions did it make? Anyone feelin me? :rolleyes:

Your acceleration at any velocity is determined by your inertia (mass), plus angular momentum (while holding all other constants the same, i.e. hp, air resistence). The larger wheels will be slower from 45-65, 150 - 200, or whatever. The only thing you gain is that you'll out-roll me when we let off the gas :D

The larger the diameter of the wheel, the heavier the "rim piece" (where the bead of the tire sits on) and the further away it is from the center, thus why I said a 50 lbs 20" has higher angular momentum than a 50lbs 16".

But hey, I realize people don't go with 20" for speed. I may be faster with my 16" steelies, but you'll get the hotties with your big shiny 20" chromes :D

Are those the chrome ones?

Hmmm, I gonna say thats debatable. I've had both size wheels, and I can feel the difference in the high end. But I will agree with you on the "hotties" though LOL

There's absolutely nothing to debate. RJ is completely correct in his physics. That is unless the world gets turned inside out and the laws of physics change.

Yeah maybe its all in my head. Maybe its the large footprint on the ground giving me the smoother, "torque-ier" feeling top end. Then again, I did get my intake installed at the same time I got the wheels...LOL

The ES starblade wheels are 18.2-18.4 somewhere there, bathroom scale goes to 0.2 lb.
The 15" steelie was ~21 lbs, the 16" steelie is ~23 lbs.

LOL. If anyone were to have weighed the wheels, I can't think of anyone else but you. I still remember when you posted about jacking up the car and testing the engine RPMs in reverse or something or another. Classic!

I tireracked the old intrepid, got cheapie alloys to replace the steelies.
What I should have done was get 17" for the new intrepid, and trickled down the 16" ES wheels to the '98. Those 15" wheels weighed 19lbs, but there wasn't but one 17" BBS wheel available so long ago.

Yeah I need to do that to the civic.
Will the car hit its rev limiter in D3?, it does in 2 (second gear start) and 1
It came with H rated tires, so 130mph in the garage here I come [I've only seen 103mph on the road], in 4th it should do 130mph with an estimated 5800rpm & 130hp, and 5th gear @ ~4300 & 105 hp (not power for a real 130mph)
but I can fit the jacks I have on the control arms, right now.
