I currently have 15x6 USDM ITR wheels with 195/55/15 Potenza RE010 tires and I'm debating if I should get the 16x7 Mugen MF10 wheels with 215/45/16 Potenza RE010 tires. The Mugen wheels are 11 lbs each while the ITR wheels are 15.6 lbs each, which is a significant weight difference, right? With tires, both setups have an overall diameter of 23.5 in, but the 16" wheels are wider (215 mm vs 195 mm). Which wheel/tire setup would yield better acceleration times and fuel economy? Can somebody post the formula for calculating rotational mass ('cause I don't have my Physics book in front of me now)? I know that many of you have dumped your 15" ITR wheels in favor of lightweight 16" wheels, so if this includes you, please post. Thanks!

Just a correction, the USDM ITR wheels weigh 15.6 pounds. The 16x7's will increase grip due to the wider tire, your final drive/speedo may be affected... also the mugen bling factor. If i had 2g laying around for wheels, id choose the 16" Mugens, Spoons or Advans.

No it won't. Both 195/55/15 (US ITR) and 215/45/16 (JDM ITR) tires have an overall diameter of 23.5.

Anybody know if the weight difference (15.6 lbs vs. 11 lbs) is significant enough for me to feel a difference in fuel economy and acceleration? I have a Civic EX w/ ITR 5 lugs and SOHC VTEC, and have noticed a slight drop in fuel economy, so I'm wondering if lightweight 16 inch Mugens would improve fuel economy and acceleration. I know many of you guys have swapped out your stock 15 inchers for expensive, lightweight 16 inchers, so if that includes you, please post. Thanks!

why not go with 15 inch forged wheels?

you also have to consider the weight of the tire, as falken azeni's are heavy as hell compared to some other tires.

its all a compromise...and for daily driving i think 14 inch wheels are ideal...you can't go with 14's so i'd say the lightest 15's possible with 195 series tires.

205 series tires work well for handling/occasional auto-x but are heavier...and on the street i would think your focus is strictly in a straight line.

I won't, but if I were to get lighter wheels, it would also be for the looks, handling, acceleration, and other benefits.

unless you race and win money.. you can spend that money in other parts to make you go faster.. of course.. if you want these wheels for looks - its all good.. and if you want these wheels to better fit the tires you like.. then its all good too.

now, there will be a difference in rotational mass.. question is will you notice it and have benefits from it? - i say not really.. - don't invest in wheels to make your car go faster..

for 7" wide wheel - i wouldn't get wider than 205 tires.

my issue with street tire/wheel is staying away from sloppy sidewall feel..

i went from 15x6.5 with s-03's to 15x7 with s-03's - much improvement.. now running kumho mx - and they do just as well as s-03' at less $$$.

If you can definately afford to get the wheels, I don't know why not to get the mf10's.

mmmmm...I Mugen MF10's...One of these days, I will get it for my car

until then, I will just dream of them

Let me know where you can get best price for BS Potenza 215-45-16?
I need in future for my JDM GM 16s.

Mugen MF10s are quite possibly my fav wheel of all time...there are lots of reasons to get them...looks, more grip from more tire, less unsprung weight, etc etc. However, better fuel economy is definitely not one of them. If you are worried about that, why drive an ITR in the first place? I get less than 15mpg on track/autox!

They are $169 each at Tire Rack. Don't know if that's the best price but Tire Rack usually has good prices.

I have the MF-10's in bronze...... they are bomb......

Have you considered the total weight of the combination? How much does the 16" tyre/wheel combination weigh when compared with the 15" tyre/wheel combination?</TD></TR></TABLE>

Here's the breakdown on weight:

15" USDM ITR Wheels: 15.6 lbs
15" Mugen MF10 Wheels: 10.1 lbs
16" Mugen MF10 Wheels: 11.0 lbs

195/55/15 Potenza RE010 tires: 20 lbs
215/45/16 Potenza RE010 tires: 22 lbs

the price for these wheels are $520 per wheel
so...
a set of wheels would run you $2080 at 40.4 lbs

or...



15 x 6.5
45 mm offset
12.5 lbs each wheel
bronze

the wheels are $430
so...
a set of these wheels would run you $430 at 50 lbs

so it costs you $1650 to save 9.6 lbs..... think about it....

$1650 could benefit in so many more ways then saving 9.6 lbs

if thats not JDM Mugen Bling then tell me what is...

I only spy 4 lugs genius


What's going to hold its value better???

GO BRONZE SE-37K!!

those look really nice!

and are lighter than te-37!!

but probably more expensive .. sorry..

your an idiot, its for comparison...

honda owners dont typically keep their cars for many years, rota wheels are fine, find me a thread of a rota wheel malfunctioning, rota didnt make such a name for itself by making shitty knock-off's.... once again your an idiot

now that i look at your statement your wrong again, rota holds its value better once again seeing as how you can only sell a used pair of mf10's for 1250-1400, so thats a 33%-40% loss of value, while you can sell a used pair of rotas for 325-375, so thats only a 13%-25% loss of value, and even if you need to replace the wheels, you still will save $1220

try running the numbers and not your mouth next time pal

I can say that Rota wheels malfunction. I have seen several pictures of peoples wheels breaking under hard driving and personally i cracked a wheel going 20 mph hitting a pot hole that was 2 inches deep. take it for what you want, but i personally think rota's are worth there money. good deal but not a strong as the "bling bling" wheels

By $520 a wheel, you're talking about the 16" Mugens, right? It's the 15" Mugens that weigh 10.1 lbs each (10.1x4=40.4). 15" Mugens will probably run around $400 a wheel if you special order it in the US, and they're $350 each if you order it directly from Japan through http://www.takakaira.com .

True for most, but not for me, since I plan on keeping the car I had since my 16th b-day for years to come (I'd like to say for life, but people laugh when I say that). When I add anything to my car, I take in consideration the long term effect it will have on my car's value. Mugen wheels will only add to the car's value. Rotas won't.

this is true, but will hardly add any resale value, and if you plan on keeping your car for so long then looking into producst based on their resale is kind of ironic, i agree that mugen is an excellent product, but your paying an extra $1000-1500 to save only a few pounds... rota is an excellent product as well... imo mf10's are jdm bling.. id much rather spend that $1500 on a pair of seats or get a really nice suspension set up if you dont already have one, good luck though

take PYMUGENITR up on this offer and stick with 15's.

i'd never run 16's on an ITR, they are simply too big.

15 x 7's offer the best of both worlds, lightweight, yet still wide enough for daily driving/occasional auto-x.

So OEM ITR wheels in Japan are too big?
