wheel weight question? 17" stock Altima Wheel weight?

[bigplayer2382]

I have a 2010 Altima coupe 2.5 with the 17" wheels. I've been searching hours (yes i searched the forums) and I can not find the weight of them for the life of me. I saw the thread for the 18" weight but I'm curious about the 17". Does anyone happen to know this weight?

And my question:
I heard somewhere (I think stillen website) that every pound taken off the wheels/tires is equal to 20 lbs taken off sprung weight, would you all agree with it?

I was thinking about switching them out for G37 rims that weigh 26.5 lbs Front, 27.5 lbs Rear. But That seems a bit heavy. Especially with tires weighing 27lbs fron 30 lbs rear.

Thanks for any and all help, I really appreciate it. Like I said, I dread asking questions like this on the forums because I know peoples first response is 'use the search feature'. Well I did to know avail Thanks for the help guys.

Technically, it's more complicated. but that statement is grossly inaccurate ! I will share some very valuable knowledge with you and everyone reading this that few consider ! The real truth is 1 lb off a wheel is equal to 1.5lbs on the chassis, but there is a gain in hp to the wheels at the same time keeping the same diameter wheel ! Here is where it gets interesting, and some may not like this ! Say you have a 17in wheel weighing 23lbs, and switch to a 19in wheel weighing say 19lbs., Based off of just the wheels weight you saved 16lbs which equals 24lbs on the chassis, then maybe a couple whp. but you really didnt gain anything in reality. Why is because yes even though you did lose weight you also moved the focus of mass further out from the axle. the further out the mass the more energy it takes to turn it, for the most part negating possible gains from just the wheel. Then there is an even more important factor, the tires! larger diameter/width tires weigh more then the 17s would in most cases. The weight of the tires is even more significant as they are the furthest part from the axle. meaning even more loss! But say the final weight for both is the same, the 19in wheel will still take more energy, meaning the same car with 17s would have a slight advantage ! So plus sizing wheels even if actual weight may be less is an acceleration loss, but you get a gain in cornering ability. It's a trade off, 17s are considered the ideal size for performance on most cars due to a huge variety of performance tires and good gain in cornering and acceleration. For maximum performance, you have to figure out the best size tire and wheel that will still give you the most grip possible, simply going with the largest width tire could mean no real true gain in handling if it isn't needed. This may be apples to oranges but this is a real fact! well, hope this answers your question , n sorry if it aint good news ...

Let me reinstate my source to save face. :p "MAT PROCESS: Shaping by the MAT process reduces wheel weight by 10%-15%. Every pound of unsprung weight savings has the effect of reducing overall vehicle weight by 20lbs. " -http://www.stillen.com/product.asp?id=E ... del=ALTIMA

Personally I thank you for that information, it made 100% sense and I had actually thought about that before but I didnt think about tire weight. And as for good news, I think becoming more knowledgeable on a topic is always good news I appreciate the post 100% and you did help alot. I didn't think tires were such a big deal until now. once again thanks alot for the post.

Thats a form of forging aluminum. It doesnt reduce weight of the metal 10-15%, It means you can remove 10-15% of the metal and still have the same strength as cast or better!
I would like to see them prove that, it is an extreme statement, iv'e heard of 10lbs, but never 20 claimed off the top of my head. As for tires, they are more important then the wheels in actuality IMO. I'm glad I helped !!!
