Do heavy wheels slow the car down alot? Heavy meaning 50lbs each, the size would be 18x8 225/45/18. And also how could Loose weight on my 2002 accord, so that it would make a difference in a 1/4 mile drag race?

 

Is that 50lbs per rim or per rim/tire?

If it's per rim/tire, what is the stock rim/tire weight?

Yes, if it's heavier than stock you'll notice the car will feel slower off the line due to the added rotational weight.

 

yes heavier wheels will slow u down, if u want to lose weight, take out the spare tire and all that, if u dont care how the car looks, u can start gutting out the interior panels and seats and anything else u feel u dont need. personally i wouldnt bother, any way you gut the thing, its still gonna be heavy, as the accords are pretty heavy cars to begin with.

by the way, are ur rims made out of lead seeing as they are 50lbs each?

 

The rim and tire is 50lbs, I think the rims are stainless steel, it's got chrome lip and black chrome inside, looks pretty sharp.

 

so whats the weight of the stock rim/tire combo?

 

But will it make a big difference on a 1/4 mile race, if i put lighter wheels? and if yes how many hundreths of a sec are we talking about?

 

Well I would imagine so - how wouldn't they?

My wheels are 11.5 each so I supposed another 15lbs for the tires? So comparitively yours are much heavier

 

Well look at it this way, the people who drag race on racing strips use lighter wheels to squeeze out a few milliseconds, or maybe a few seconds depending on the weight. 50 lb's for the tire + Rim is high.. but I don't think it will do THAT much on bogging your car down. It's just like having another 200 pound person in your car.. although in the car and on the wheel is different. But it still does slow down your car. In another note, the rim size and tire size also take effect in this area.

 

I just put 16" wheels on my girls car, they weigh 16lbs w/o tire and 44lbs. after mounting 205/55-15, the stock 15" wheels w/ 205/60-15 weighed 36lbs, all this weight is unsprung weight which is worse for performance than your fat friend sitting shotgun. Switch to stock before you make a run or run then switch then run again to see how much it's effecting your times

comes out to about 40lbs or so stock rims are around the 15lb range, and tires are about 20-25lbs or so.

 

more wheel weight is a bad thing, ditto on that.

 

96black it's actually worse than having another person because the weight is not spread around the car but actually on the part that torque is pushing on.

i remember an problem about that from an old physics class

the extra weight has an effect on every aspect of the wheel's movement. acceleration, deceleration, turning

remember it will also be harder to brake with heavier wheels...

50 lbs sounds extremely heavy though. i had an f150 years ago with 33 inch tires and billet rims. they only weighed 65 lbs each.

 

touring accord is right. Its all about rotational weight.

take an accord with stock wheels and tire sizes, and line it up with an accord of the same model/trim with 18's on it and guess who's going to pull ahead.

the accord with the stock wheel size.

145 hp would feel more like 120hp off the line. Guaranteed. And someone else mentioned it in here, but because of the added rotational weight, your going to notice a significant difference in braking and brake wear.

Ditto. It's going to take more torque to turn that heavy tire. and it's going to take more time to spin up. Do a simple test just to show. take a CD add some weights all around and compare it without it. It takes more force to spin it.

haha nice example dude!

 

Damn, what kind of rims do you have? I have 18's - 225/40/18 and they aren't 50 pounds with the tire....and they're not racing rims or anything.

 

He wants to look good and pimp around when he's going down the lane. Girls couldn't see your face if you're going fast. =D

My 15" stock (96 Accord Coupe EX alloy rims) with tire is around 38lbs.

 

locobanana is right about the brake wear. I would be concerned with it over acceleration. The brakes need more to slow the car down so brake fade becomes more noticable. If you regularly run street style tracks or just like to do a little backroad time trials, be easy on them until you get a new feel for your brakes with all the extra weight on them. Your dampers will feel less responsive too.

 

why wouldn't extra weight slow you down. bottom line is don't run larger heavier rims at the track. chrome/steel anything is heavy. your asking to get spanked. have you ever noticed a car with 18's at the track do times great times. use stock rims. if you want larger rims at track, buy lighter ones and make sure they are close to the weight of your stock rims. i will warn you, good light weight rims are expensive.
