I got tyres fitted to front wheels locally and they were out of balance. He 'tried' to balance them on 2 further occasions and failed ( I didn't witness any of this 'work') . I took them to another garage and saw the process. He put first one on the machine and found it was out of balance it had 10g on, which he removed and starting form scratch he put 15g on 10 in one place and 5 in another. Onto the second wheel IT HAD NO WEIGHTS, and was out of balance, he added 10g. Both are now good, I suspect the first garage couldn't be bothered or his equipment is faulty, and the lack of any weight is IMHO VERY unusual. I'd expect some weight, even 5g to be necessary always.I imaging the chance of getting 4 wheels/tyres requiring no balance weight would be about the same as getting a winning lottery ticket. As an aside, years ago I even had static balancing done on a set, using a spike and small spirit level and (surprisingly) the results were excellent.
I'm assuming you mean he put 10g on either the inner or outer side of the wheel & 5g on the other side. If he put 10g & 5g on a different part of the same side of the wheel then that's not the correct way to do it, & I see this a lot. What they should do in this case is move the 10g round towards the 5g until the 5g is cancelled out. A lot of tyre balancing staff don't do this but they should.

That is crazy. Slightly off topic (only slightly)I wanted the wheels of my trailer balanced. Everywhere I rang they said 'they don't need it'.... Just because they are small or trailer???????. But as soon as the trailer is on the back there is an imbalance which is felt. Also it doesn't matter how small the wheels are, if they are out of balance and spinning (faster because they are smaller) it will show. I checked to make sure they were round! Eventually I found someone willing to do it (mobile guy) and he ended up sticking weights on because of lack of lip to clip them on, but it works - no more wobble at speed. It's simple (ish) science really, why can't tyre fitters be bothered??
I had the same with my winters on my SLK - tyre fitter guy who was otherwise brilliant telling me that rear wheels don't need balancing.

Yes, correct, 10 one side, 5 on 'tother

What! Rear heels don't need balancing - what is wrong with these guys?

I bought two Dunlops from blackcircles and had them fitted locally at a place I had not used before. I was impressed that they had Placed the yellow dots alongside the valve holes and that only small weights (5g?) were needed.

When I needed another pair I went back to the same place. One tyre was correctly mounted, the other was not. It required a larger weight (20g+?) to balance it.

I wondered about the red dots on the rims of my works Ford Ranger for several years before stumbling across the tyre bible and learning the reason they were there.
Wow, my mate fits tyres for a living and I don't think he knows this. Every day's a school day!
