After a balance, what would be considered alot of added weight on a wheel?
 

I've got the other thread going about my warped rotors and vibration issues over 60+ mph. I just checked the tires to see how much weight Limbaugh Toyota added to balance them. The front driver's side tire has 60g on it (2-30g weights) and the front passenger has 65g on it (1-30g and 1-35g). The two rears have only one weight each, but I can't make out how much they weigh. Both look to be smaller than either on the front. What's the deal? Is this an insanely large amount of weight on these front two or is it normal?

Make the vibration go away please!!!!!!!! I'm tired of wasting my time on this issue, but I'm afraid I'm going to end up back at Limbaugh Toyota bright and early Saturday morning and have them balance them over and over again until they get it right and after each time they do it, go test drive it on the interstate. Help!!!!!

Where's tire boy when you need him....jimabena :think:

You could switch the rear tires to the front, but those weights sound normal to me. I've had more weights on my swampers than that.

Yeah, I'm used to having a bunch of weight on my mudders so I couldn't tell you if its a lot or not...wait for others to reply I guess.

Fink:devil:

that sounds very reasonable to me, 60 grams is only a little over 2 ounces, I have over 18oz on one of my 33" swampers, that's bad!!!! It is common practice however to put the tires that balance the best on the front, you might rotate and see??? You can also rotate the tire on the wheel to try to get it to balance better.

I've never seen wheel weights measured in grams in the U.S.??

I have no freaking idea. I'm a mechanic and have access to a wheel balancer, my 4Runner has a horrilbe vibration in it at 60+ MPH and I've balanced them several times. Everytime I balance it, its never true after so many miles on them. I've tried rotating them to even treadwear, different tire pressure, etc. I've even done my own alignment just to satisfy my mind and everything is dead on. If you find out then please let me know.

Do you torque your wheels down or use an impact wrench? There was a big thread about using a torque wrench to aleviate that problem. Also heard certain tires always vibrate. Just trying to help.

I have a torque stick and use the correct torque setting on my impact.

Your weights sound reasonable... the heavier the tire is, the more weight it's going to take to balance it. But also check the insie of the wheel - in cases where I need a ton of weight (3+ weights per wheel), my dealer will put 2 on one side and 2 on the other.

Is this the first time the tires have been balanced and you've seen vibration? How many miles do you have on the tires? What kind of tires are they (brand, model, size)? Some people have had issues with tires not even being round, so balancing doesn't do much. Have the dealer balance them, then give you the road force numbers. Anything over 16 (I think it's 16, perhaps it's 18) is generally considered unacceptable/defective for a typical road tire. Now, swampers probably don't apply because they are so heavy - I'm not sure about other MTs... but it might be something for you to look into.

Jackson,
When I first got a new set of tires about 4 months ago, I bought 265/75/16 Dueler Revo A/Ts and they vibrated like crazy. I returned them and got a set of 265/75/16 Michelin Cross Terrains. The vibration issue really didn't start until I put the Revos on, and now it won't go away. The highest road force number that I've got on the Michelins is a 14 and that is very acceptable. Unacceptable is anything above 30 from what I've heard. These Michelins have less than 1000 miles on them and are supposed to be the top of the line. That's why I chunked the Revos because I orginally thought that they were what was causing the vibration. Guess not. The road force balancer would have found any wheel that was not true and/or damaged and would have found an out of round tire and neither place (A&R or Limbaugh) have said anything about one of the tires being out of round. I don't know what the answer is, but from all the research that I've done on Yotatech, this sounds like a very common problem, some more easily solved than others.

BTW, the steering wheel doesn't shake nearly as much at 60+ mph as it did before I had the rotors replaced yesterday, but the vibration can still be felt in the seat and can be seen by looking over at the passenger seat or the driver's side sun visor.

Matt

perhaps the driveshaft requires balancing, but if it started as soon as the tires were replaced, i would suspect something else. bent wheel(s) maybe? have someone drive beside you and watch your wheels spin as you drive.

man you have had a crappy time with the whole new tire issue.
You are sure it is not an axel or driveshaft issue?
keep us updated

How's about an alignment?

The alignment is fine. It may be ever so slightly off, but definitely not bad. I'll probably try to get that done this weekend as well, but I know that's not what's causing it.

Matt

Did you ever check your steering rack like I suggested? Something is snafu w/ the steering, ball joints, alignment, or possibly (but not likely) the driveshaft.

Yea... my second thought was also play in the steering - perhaps tie rods?

that's EXACTLY what I told him about a month ago, but the dealer can't find anything wrong.

I assume it's a competent dealer? I had one dealer tell me they couldn't do an alignment because there was too much play in my tie rod ends and they needed to be replaced. Took it to another dealer (my trusted dealer) and they said that the other guy had no idea what he was talking about... that they tie rods were in perfect shape, and an alignment wouldn't be a problem.

Idiots...

How would a problem with the steering translate into a vibration issue at highway speeds?
