Hi,
I have had some problems with my new Goodyear MT/R tyres. I purchased 4 tyres and sunrasia rims. I wanted the ROH rims and specified that when buying, but think I have got Speedy rims??
I have had the tyres balanced 5 times by two different
places. The last was today by Bob Jane, a Gold Balance. They spun a wheel on the rim, and balanced the other three.
No matter what is done, or who does it, the car always seems to get the shakes up around 90 - 110 kmh. The shakes aren't as bad as the first time they were balanced, but are enough to be annoying, especially on longer trips.
Does anyone have any ideas?? I am feed up with going back to tyre
places. Both
places have said the tyres are round, and the rims seem ok. The vehicle is a Hilux D/C. I am running the tyres at 32psi front and back, and they are 31x10.5x15 in size. Could the tyres have something wrong that doesn't let them balance correctly, or could it be the rims??

If you have bought thesame diameter tyres as b4, then it is probably the tyres or rims. If they are bigger diameter,or if the offset on the new rims is different, maybe the wheel bearings.
Try lifting a front wheel and rocking it to feel any slackness there. Alternately go get a wheel alignment and ask the guy to
check for possible faults that would give you the symptoms you have.
If all is ok, take em back and say you dont want tyres that cant be balanced, hey are unsafe, change em.
BTW ROH will have a beed of silastic around the outer rim where it meets the part you put the nuts on.

You would think if it was wheel bearings the place where he got the balance done, would have picked it up. Maybe a caster
check might turn something up.

Guys,
I don't think it has anything to do with wheel bearings, as these are my second tyres. The standard road tyres are fine, smooth as silk. Also the vehicle is less than a year old.
Question, when the tyre guys rotate the tyre on the rim, do they just guess where how much to rotate it, or is it more scientific than this?? My guess is that the rims are slightly off in balance, and the tyres are also. Perhaps I will get them to swap tyres on the rims. Also the steering has no shake, it seems to be vibrating/shaking in the body, so I think it is the back wheels that are the problem.
Any more thoughts greatly appreciated!!
Thanks
Andrew

Andrew,
I have just cured this very same thing in my Hilux. I have 30x9.5x15 BFG on ROH rims and in the 5,000 kms I have had them have not been able to get them balanced - that's 6 balances, of which I only paid for the first one. My symptoms were the same as yours - wobble through the whole car, indicating ALL tyres/rims, and especially noticeable around the 80 - 100 km mark.
Just this Monday I finally had a gut full and took the car somewhere else where they have a machine that measures how much out of round, and precisely whereabouts out of round, each tyre and rim is. Then they match a tyre with a rim and put it on in an exact way so that the tyre / rim combo is as balanced as it can be before it is actually balanced (if that makes sense?)
Anyway, it's a bit hexi - cost me $100 ($25 per tyre) and they have the only machine in WA - but it's the best $100 I've ever spent on my car and I'll be going back there again.
I found this info on this site about 2 / 3 months ago and filed it away for future use, and then remembered it this week. Once again this
forum comes up with the goods!
Keep all the good info coming trendsetters,
Cheers, Jim

Jim,
I went else where yesterday, for balance number 5. Didn't fix it obviously, and also cost $16.50 per wheel. Do you know of any of these machines in Victoria, or how to find one???
Info much appreciated!!

Guys,
The place I went to in WA is "Richards Tyrepower" on
Scarborough Beach Road. I don't know the name of the machine - Diamond may be able to help with that?
And no, I don't have any ties with them - just happy to recommend something that works.
To those recent posts since my last on this thread. I agrre with you all 100%, there is no doubt that it is the tyres and or rims. All of
mine however were within specs, that is they were round and had no obvious defects, and yet two of them still spun up (the day after an ordinary balance somewhere else) with a 25kg "throw" in them!!
Anyway Andrew, I hope it gets sorted for you one way or the other.Cheers, Jim
