Sup guy. Okay basically I just recently got some new rims and tires they are some 15s w/ 195/50r15 if I remeber it correctly. Got them from wheelsnext.com they were balanced and everything. So when I got it I basically just took off my old tires/steelies and put new ones on. Anyways so my problem/question is because my new rims/tires is balanced out and everything already should the car shake at 80+mph (highway/free way)?? Don't know too much, but only reason I can think of for it to shake at 80+mph is maybe the speed rate for the tire might be a tad over 80 and lower? The tires are some Hankook Radial K106.

But this is for a 95 civic ex coupe with a tad over 120k miles on it. Everythings still all stock yet. So anyways help/answer as to why would be greatly appreciated. TIA

 

ALSO note: Just woundering if I countinue to drive it a tad over 80+mph would it hurt my cars suspension or anything? can I be damaging the way my car runs?

 

There are two kinds of reasons why you can have a vibration. One is a problem with the wheels or tires. The other is a problem with the rest of the car.

Try switching back to your old set of wheels and tires to make sure they don't vibrate at the same speeds. If they don't, then the problem is in the new wheels and tires. If they do, then the problem is on the rest of the car (in which case it's probably a suspension problem i.e. worn bushings, bent control arm or tie rod, etc).

If the problem is the new wheels and tires, it's possible they were balanced improperly; it's also possible that you have a defective wheel or tire. Contact the place you bought it from and ask them what to do. (If that's the case, it probably won't hurt the car to drive it on them in the meantime, but I wouldn't; I would switch back to your old wheels/tires till you get this resolved.)

 

Well all I can say is I had stock tires 14s then went to Si rims 15s and now new rims 15s. And before new rims nothing, no shaking or anything over 80+mph so I don't think it's the car/suspension or anything. However I am looking to replace brushing and suspension coming spring/summer. I mean the car is kind old or is old but it's not one that's been beat on or anything was a one owner driven buy a lady and thing is pretty much mint and gr8t shape. So I don't know. Only guess I have is tire speed rating is low maybe, which I think might be the case? But how would I check to find out the rating? To know if this is the case? Anyways thanks so far.

 

Tires don't vibrate because of the wheel size or the speed rating.

I just wanted to show you a way to be sure you can rule out anything OTHER THAN the wheels/tires, so you're sure that's where the problem lies. (The wheel/tire vendor is probably going to ask you the same thing.)

 

do you have hubrings to go with the wheels and tire's for your car????and tho other problem like nsxtasy stated is that the wheels and tires are not properly balanced

That's a very good question. Thanks for mentioning it.

What vtecsi is referring to is this. The center bore is the big hole in the center of the wheel, and it's designed to precisely fit around the hub on the car. Aftermarket wheels sometimes have a bigger diameter center bore from stock. When they do, they should be supplied with "hubcentric rings" that fit onto the wheel to narrow the diameter to that of the hub. If they're not, it's possible that the wheels and tires are balanced perfectly, but are not precisely centered when mounted on the car. This can cause a vibration. You can minimize it by tightening the lug nuts while the tire is off the ground, but the best way is to get the hubcentric rings.

Another possibility - do you have the proper lug nuts for your new wheels? You need to have lug nuts for which the shape of the seating area (the area where they come into contact with the wheel) matches the shape of the seating area on the wheel, as illustrated below. Honda/Acura wheels and lug nuts have a ball-shaped seating area. Most aftermarket wheels have a tapered (conical) shaped seating area, and you need to use lug nuts that also have a tapered seating area. With the wrong kind of lug nuts, the wheels and lugs are in contact only around a circle instead of over an area, and can easily loosen. You can buy the proper lug nuts inexpensively at your local auto parts store or wheel/tire shop.

Again, both of these possibilities - lack of hubcentric rings, and improper shaped lug nuts - can cause wheel/tire vibrations even when the wheel/tire is balanced properly.

 

Well first the replies...well yeah I made sure I had the right/correct lug nuts as I went to a local tire store and they are like an acorn shape type almost like the stock ones so that can't be it. Cuz it fits right to my hub/bolts. As far as space hub? Or whatever the holes from rims bolt or fit nicely on my hub so I figure I should be good when I first got them. SO yeah now it's just the vibration at over 80+mph. I guess if no one else can think of anything else I'll give the place a call and check. But before that I looked and looked all over my tire wise to try to find a speed rate of some sort or whatever. Is it the number next to the tire size and etc. like "195/50R15 82H" something like that pretty spaced out. So you're saying even if the speed rate is like say 100 or whatver it shouldn't make a difference at 140mph and not shake then no? If so than maybe I'll stop driving it past 82+mph. Anyways thanks so far gotta run for now.

 

Yes, the speed rating is the "H" part of where it says 82H. (You can learn more about sidewall markings here. Yes, the speed rating has NOTHING to do with vibrations. Your H-rated tires are good up to 130 mph. If you're going 140 mph on 130 mph tires, that can be unsafe - but the tire may just fail on you, not necessarily by giving you a vibration first. Keep it under 130. But that has nothing to do with a vibration you feel at 82 mph.

Are you sure your car wasn't vibrating with the old tires at high speeds? Is it possible you never drove that fast on them recently, because you weren't trying to see how well they felt the way you are now with the new tires? It might be worth spending the half hour to swap them back on, just to rule that out for sure.

 

Well now that you've said that I'm thinking it could just be the rating even though you said it's not and I'll take a look at the speed rating to learn something else new. But that 82H is the rating eh??okay.

But as far as the swaping of the old tires, yeah it would take some time but yeah before the new rims/tires not cuz I speed around town but cuz of work i travel on free way/high way do about the same speed 80+mph no shaking or nothing to the wheels or anything. I mean even on the old tires Si rims which I'm sure was blanced out for an Si and old stock tires/steelies I'ven taken the car up to a tad over 95+mph on trips and nothing runs smooth I mean can use new suspensions but runs good. So yeah I guess it could be that it's not balanced right or whatever else but yeah I did drive just as fast if not faster in my old tires. But thanks I'll take a look at that speed stuff and after this whole post is over and yet still nothing I'll call them up and see what they have to say. Anyways thanks once again I'm still keeping in mind everything else you said as well, but I just don't see why the shaking to the wheels didn't happen before in my old tires going way faster than my new tires now. Thanks

Then it sounds like you've ruled everything else out, and the most likely cause is in the balance of the new wheels/tires.

ITS NOT THE SPEED RATING AT ALL! PLEASE LISTEN TO WHAT THEY ARE TELLING YOU!

the speed rating is merely a rating stating the speed in which a tire can withstand without failure. ur wheels are either improperly mounted or your tires are not properly balanced. call the place where you bought them and ask them, if they are no help take them to a tire shop and have them all rebalanced.

i work for a performance wheel and tire shop, so im speaking from experience

 

and also if your going to ask for help on a forum, LISTEN to what other people tell you. theres no point asking a question if you are only going to ignore the answers

hey hey I am man, I said I'll keep in mind all what he told me and so no I didn't just ignore it all..i cuz I want to know why..I said I don't know much so I'll check it out what he told me and learn while I'm at it

But alright man thanks that's all I can do now is call them...
BTW since you work at a wheel and tire shop how much average they charge for something like this just to get an idea before i call and go in afterwards? Thanks

thanks nsxtasy...

Just for balancing? Probably about $10 a corner.

 

u may have a bent rim or rims.. take it to a tire store and ask them if u can have it spun on the balancing machine and see if it shakes.. i found out the other day that i have 2 bent rims... i was pretty pissed off about that.

 

Sometimes a bent rim can be repaired by a professional wheel repair shop.

 

I'll keep that in mind as well. I'll look at it first thing in the morning just to check. But when I got the rims i remember laying them flat to the ground so hopefully not, otherwise I'll be mad as well. But yeah still haven't gotten to calling the place yet. Will try to make time to stop after work at a tire shop instead. thanks

That doesn't mean it's not bent. The centre mounting portion could be un-parallel if you know what I mean. Go to a mounting place and get it check out.

 

true, that's right forgot about that part. Will do. Thanks

 

sup guys! Anyways okay so I was about to have my rims/tires check this past Friday 11-09-06. But early that moring I thought I give it a try again and see if the shake was still there. But when I went pass 80+ mph nothing, no shakes. Still I was going to have it check, but then with the crazy weather it rain/snow mix so it was too nasty and too dark so I decided to hold it off till after work on Sat. today. But then I didn't stop in.

So again when i went out to work this moring I was pushing it, this time to 95+mph, nothing. So with that I'm going to hold off stoping by at the tire shop just yet. So when no shakes happen on Friday and today I thought to myself at work what could it be? Well I looked at it and only thing I can find out was so far since I've had the new tires i've only put around 1,300 miles on it. So I concluded that maybe it was still in it's "break in" peroid? And that was looking at the site you give me, thanks for that (nsxtasy).

So I don't know,no shakes now? I mean weird but it's a good thing now . So just thought I share this and woundering if there's anything you or anyone can say more on this. Though I'll stop at a tire shop this coming week just for my own safty and have it check. But could it be taht it was in it's "break in" peroid for the shake? I mean I Don't know but around after how
many average miles are you until you pass the 'break in" peroid on a new tire? anyways thanks man

 

'Break in' period for tires usually has to do more with traction and the wearing off of the mold release compounds.

If you are complaining about snow and ice what could have happened it this: (it happens to me every winter a few times) Sometimes when you park your car ice and snow will build up in the inside or outside of the rim but only on one side, this causes the tire to be off balance. From personal experience this is only felt during highway speeds. This can, obviously, also occur with mud and other debris.

Anyways, it looks like your problem is gone so enjoy it!

Cheers.

I'll take that

Oh no it wasn't snowing or had no ice to cause the shake. It just started to snow/rain mix on friday evening. But shake started since I had the new tires/rims. Well I asked for some good all season+ snow tires and they gave me the Hankook Radial K106 they hold up fine when it rain/snow mix so hopefully no problems when it starts to really snows and ice up. It should be fine cuz I last parked it on some nasty hard mud and thing was pretty good it broke up the mud in between the tire groves and everything, so yeah. Anyways hopefully no more problems and yeah could just been in it's "break in peroid". Thanks

 

could be ball joints, did it do it before your new tires??

Thanks for the input, in future please read the entire thread before commenting. This possibility has already been discussed.

cheers
