Let's not get carried away. Who exactly is "a lot of people" ?


As far as I'm aware there are maybe 10 people here with 18" wheels and I havent heard complaints.

*I* have 18's and get a little bit of tire rubbing but as I've stated before I ran an OVERSIZED tire, which is why this happened. I have 225/40/18 which is about 1" greater in diameter than stock. I purposely chose this tire to get added protection due to huge potholes in my town. I also have my car lowered 1.8"


If you stick with the correct tire size you will not have ANY problems running 18" wheels.


3pc wheels will make your car slower. I recently put my stock wheels on and I can feel the car accelerate a lot faster. I think my next wheels will be 1pc 18's

I don't think a good 3pc wheels would weigh more than a 1 piece wheel. Why would it be slower? Am I missing something with your little wink at the end?

[b-b00gie]

The replacable steel lip on 3pc wheels is a lot heavier than an all alloy wheel. Not to mention the added weight of nuts and bolts.

Even Racing Hart 3pc wheels are heavy.


Remember the CP-35 1pc ultra light wheel? Notice the new multi-piece version isnt marketed as being ultra light weight?

I don't mean to be an ass but what's the wieght of your 3pc wheels? I wish wheels manufactureres would list the wheel weights.

I dont think you're trying to be

I'm not sure on the weight but they are pretty heavy.


My friend owns a shop and his main sales flow is wheels. I've spent countless nights helping him out moving, loading, unloading wheels. I can tell you 3pc wheels are significantly heavier.

For example if you compare the same size Racing hart C5 3pc vs the 1pc. Or say a 19" 3pc AC Schnitzer BMW wheel vs their 1pc version. The difference is about 5 to 10 lbs per wheel depending on size.


I'm willing to bet that 99% of 3pc 18's are about 5 lbs heavier each than a 1pc wheel. At minimum thats 20lbs more overall... but its also rotating weight, not dead weight.

No shit? Have you actually weighed a 3pc wheel? I though one of the benefits of a 3pc wheels was the light weight. I don't see the point of paying 2x the amount for something that just looks good. I found this here: http://www.butler-eng.com/techsupp/p...g/chapt2e.html

The three-piece modular wheel offers the most versatility in size and application. It is constructed of two outer halves that make up the rim (made from aluminum alloy) and a center section (made from magnesium or pressure-cast aluminum). The construction allows you to change the individual pieces to achieve the required offset and back spacing. It is very lightweight, so vehicle unsprung weight can be reduced which may improve handling. Also, a damaged section of this wheel can be repaired by the manufacturer at a cost much less than a new three-piece wheel.

The disadvantages of the three-piece constructed wheel are the relatively high cost and the need for periodic re-torquing of the bolts. Also, if the seals are not perfect, they can leak air.

I'm still wondering about this.

[b-b00gie]

Jason... I think what they are comparing is what is confusing you.


Lets use some examples...

Racing Hart C5 EVO - this is a "cast alloy wheel". Cast alloy is lighter than "forged" alloy a disadvantage is that the alloy is weaker because it is less dense.


Racing Hart C5 3pc - the center of this wheel is "cast alloy" and the two lip pieces are "forged". The forged lips are much heavier and stronger. The advantage of 3pc wheels is this strength and also being able to repair damaged wheels without replacing the whole thing.



Now... what that article appears to describe is the difference between a wheel like the "Racing Hart C5 3pc" vs. a 1pc "forged" wheel. Obviously the 1pc forged wheel is much heavier. Most 1pc wheels today are now "cast" not "forged".


If I had a scanner I could show you some wheel weights. There was an Import Tuner about a year ago that had a wheel buyers guide and included weights.

Brian: you dont have any wheel weights for Team Dynamic Wheels do you? Im looking at the 17" Monza's

See I have to disagree here. A forged wheel can be made lighter because the forging will create stronger material. I don't know where you read this but it's totally backwards to everything I know about wheels (ie forging and casting).

A quick search confirms my suspisions.
http://www.tirerack.com/wheels/tech/construc.htm

Forging is better than conventional casting and compareable to the other high pressure casting methods. If Racing Hart is making heavier wheels than their EVO wheels I don't expect they'll ever sell a 3pc wheels again. Paying 2x the amount for a heavier wheel is just stupid! I can get a wheel just as strong and light for the same if not less cost. I would suspect there are some serious 3pc wheels out there that would blow your mind at how light they are. Lumping all 3pc wheels together and saying they are heavier than a cast wheel is a generalization and I doubt its true in all case.

[b-b00gie]

Well.. I'm not sure anymore now either. It may depend on the construction materials.


I'm gonna dig up those magazines that had the wieghts listed and I'll tell you what I come up with...


I did get to weigh one of my wheels though. I have one which I damaged that is not on a tire and it weighs in at 25lbs 18x7 3pc

A typical cast 17" wheel weighs in at about 22-23lbs. So considering that you have 18" it isn't all that heavy. Thanks for the heads up though I was always going on the assumption that all 3pc wheels (over $1800/set) were going to be relativly light weight. I'll have to look out for weight now too. I DON'T want to buy expensive and heavy wheels.

[b-b00gie]

OK.. I had a look (May 2001 Import Tuner). The weights vary greatly.

Most 17" 1pc cast wheels weighed between 17 to 21 lbs with a few as high as 23 lbs. 3pc 17's weighed in at 19 to 24 lbs.

Most 18" 1pc cast wheels listed came in between 19 to 26 lbs. The 3pc wheels varied from 22 to 30 lbs each.


Now please note these were all wheels from different manufacturers and different models, so you cant make an accurate assumption...


There was however, ONE wheel model which was listed in both 1pc and 3pc trim. The wheel was by Oettinger (famous VW/Audi wheel) and the size was 18x8. The 1pc weighed 25 lbs and the 3pc weighed 29 lbs. The ONLY difference was the 1pc vs 3pc. The model and design was the same!


Now... I'm not gonna base my whole argument on just one wheel. It looks like the brand and individual construction techniques have a lot to do with the weight.

...and probably twice as expensive. I guess you really have to spend a load to get some light 3pc wheels. Oh well at least I didn't blow a tonne of cash on some shitty heavy-ass, nice looking 3pc wheels.

and on that note-

i have a hook up for some rims that are copies of the big name brands...

example: konig tantrums are going for 1800 new. i can get copies for those which will be 17x7.5 (rim weight = 19lbs) with tires for ~$800.

the reason why they're so cheap is because they might have a tiny tiny nick in the paint or a bit of orange peel in the finish. (i will take some photos soon)
