I have a question to anyone who knows the weight of a 94 Accord EX rim? I posted on another board but did not get a definate answer. I am debating on getting the Tenzo Sinko-R in a 17x7.5 which weighs 18.7lbs vs Stock 94 Accord EX rim 15x7.5 which weighs ?? Weight reduction is now a concern of mine when modding my 4th Gen lets say its on a diet so any help is greatly appreciated.

Sorry, I don't have a definite answer for you...but I'm 95% sure that the EX wheels aren't lighter than that. Low 20 lbs I'd say - 19 at teh lightest. And they're only 15", so you have to put a lot more rubber on them to meet the right OD.
IF you can get 17s that are that light you'll be running a 40-45 series tire which is much lighter than the Ex's 55 series. You'll also have a lot more width which = traction. The EX wheels are only 6" wide.
Scottigee thanks for the reply! I had a idea that the EX's weighed around 22lbs but was not sure. Get this the Sinko 15" only weighs 12.4lbs which is a consideration as well. But I already have my car lowered to accomidate 17"s but they are now bent due to the 40 series tires and rough roads. Those 40 series were a big mistake and I'm definately going with a 45 series tire or larger even if I have to raise my car. Would you or anyone happen to know the weight of 45 series tire for a 17"rim vs 55 series tire for a 15" rim. Sorry for being a pain but I'm trying to take into consideration all the factors so I can reduce weight which = a edge over the competition
7 spoke EX rim is 15 x 5.5
Just wanted to clear that up.
Also, you can put 225-50-15's on an accord and have a smaller OD than with a 17 inch rim. Harder to bend rims with a 50 series tire on there.
Also, it depends on the tire on the weight issue. Z rated tires usually weight more than W rated and so on.
I've had the 225-50-15's on my car and was overly happy with the performance and traction of the overall car. Plus I reap the benefits of having the 7 spoke EX's on my car

What I've learned in physics class:
More width does not equal more traction.
It does however equal better turnings/handling.
So your saying that a 175-85-13 has the same amount of traction as a 245-50-16?
Is that PHYSICS?

Now you're talking contact patch, not straight width.
True, a bigger contact patch does not always equal better traction because if the tire width is too big for the wheel it gets all gushy and traction is lost.
But a 7.5" wide will offer a very noticable difference over a 5.5"
sorry if my info was a little off- I don't have my EX anymore, if I did I would measure and weigh the wheels myself. But I think I was in a close enough range to offer valid advice. The wheels you are thinking of getting will be much better than the EX wheels. Lighter, wider, probably better looking too. Got pics?
maybe coefficient of friction will tell you the amount of traction? hmm, been a long time since college physics lol. but the ex are 15 x 5.5, i dunno how much they weight though.

they won't be lighter. also even though they are pretty close, the 17's have more rotational mass or some thing I really don't understand that too much, but basically if they weighed exactly the same, the 15's would allow you to accelerate faster.

Rotational Mass is determined by the weight distribution of the cross section of the wheel or tire along their shared radius. These days it is quite possible for a 17" wheel with low profile tires to have less rotational inertia than a 15" stock wheel on factory series tires.
That's just a general fact - I don't have the exact #s for the wheels we're talking about so I can't make a judgement either way. All I know is Honda wheels are too skinny and they usually take 10 to 15 profile points above a sporty riding tire - light or not.
93AccordEX - you should blur your plate # in your sig picture. There are assholes out there who can either report your car as having hit theirs or if they see something they like in your posts they can track you down and come get it off your car. Just a word of advice.
Thanks for all the replies!!A lot of info flying around out there. If you want to take a look at the rims that I am talking about go to tenzoracingsports.com and take a look at the Sinko-R or the Sinko they are a knock off of a Mugen style rim. I called the Tenzo distributors to the USA today and got some weight specs on both styles in both 15" and 17" they will give you the weight in kilos but it is easy to convert I just multiplied by 2.2 which is how I got the weight in lbs. So taking into consideration everyones imput will the 17"rim with tire be lighter than the 15" EX rim with tire due to the 17" rim only weighing only 1lb heavier than the EX rim and having less rubber on the tire than the EX rim, or am I better off getting the Sinko in a 15" which weighs 12.4lbs and putting a 55 series tire on it and save 5lbs per rim and tire over the stock EX rim:

imo, if your going to get light wheels get 16s at least otherwise run stock wheels if you want 15s.
