Gen 4 SZ5 Alloy wheels and 215/75/15 Toya Tyres - Balancing proving challenging
Anybody had problems balancing their new tyres? I've purchased 215/75/15 Toya's and at about 65mph get some vibration. When the tyres were fitted they indicated some challenges mounting the wheel to the balancing machine but advised that it was all fine. I did not take my car back to the original installer as it was not particularly convenient so stumbled across a local mobile fitter. He too had a problem mounting the wheel but said it was ok and balanced one wheel, the spare wheel. He was very much "Chasing the weight" and took about 5 goes and resulted in about 15 stick on weights being applied. At the end of this it was reporting 0 5 so ok but was concerned about the amount of weights and how difficult it was. So opted not to do anymore.
Decided to take my car to a trusted mechanic who has done work for me before after doubting the competence of the mobile fitter.
However same problem. Mounting the wheel was challenging and he too was "chasing the weight". What appeared to be the biggest problem was that the stick on weights on the outside of the wheel could not be applied far enough out. For testing purposes he stuck weights on the outside of the wheel and was able to balance ok but trying to stick weights in the inside of the wheel so not visible when mounted was very difficult.
So I think I did a disservice to the mobile fitter and have come to the conclusion given the wheels have a large offset this makes applying the weights to the correct part of the wheel difficult. Of course could use old fashioned weights fitted on the outside of the tyre but not keen as it would damage the alloys and encourage corrosion.
Did they use the bolt holes to mount the wheel to the machine ot the centre bore with those cones? The wheels are bolt centric so the cone thing gets unrepeatable results.

Tried both. Landed on having the wheel mounted direct to the machine. a mounting bracket/tool which had the correct hole spacing was then fitted to line up the wheel with the locking tool then fitted. Not sure about correct names. But he also tried the cone as well and believed best results was with the alternate option.
Its a bag that gets put inside the tyre with small plastic beads in to a certain weight. Fit tyre as normal but dont balance. Instead take it for a drive. The bag will burst after a short drive and the beads are free to spread around and balance the tyre. You get a very quiet noise when moving really slowly from the beads moving about, they then spread out once up to speed.
