Taking my wheels to a local precision welding place. Good rates for making my wheels round again. However something occurred to me.
Somebody said spin the wheels up with no tyre which is a great idea. After the repair I’m presuming a zero zero balance would be perfect but what realistically will I see after the repair? 10g without a tyre?
As said just curious 😄
-
There's no guarantee that a straightened/repaired wheel will be perfectly balanced. Not all damage can be repaired either; none of the local firms will straighten a FWD offset wheel that's buckled on the outside edge.
-
These aren't necessarily buckled i.e. When spun they're not bobbing around everywhere. However they take a lot of weight to balance and are really difficult to balance. So I figured get them round as possible and fit my nice new tyres and rebalance them.
Any other suggestions?
-
If the wheels are off balance significantly with no tyre, use that info to fit the tyre slightly differently using the heavy bit of the tyre to counteract.
-
ok,so how would one find the heavy part of the tyre? Forgive my stupidity

The heavy bit is always at the bottom when you've got a puncture. The strange thing is the heavy bit moves if you drive forward a bit with flat tyres. :D

You fit tyres, right?
So you already know (or you shouldn't be fitting them ;))

Oh come on mate give me a break lol when I fit I put the paint mark by the valve and balance accordingly. There's no rocket science.
So yes consider me your dumb minion and please explain...

it's the black part :y
not the see through part in the middle ;D
-
::) ;D ;D ;D

new tyres come with a dot on the sidewall that you put opposite the valve ,so i'd think dot is heavy part :-\

Seek and you shall find .... :)

Ok, let's just be clear. Yes I know about the paint dot. And my understanding was the manufacturer puts that on and you fit that with the dot next to the valve. I didn't know that was deemed to be the heaviest part; merely where they felt it was optimal to balance. Now I know :y

Fat chance of Mr Clutch 'fitters' knowing this, or acting on it. :-X

So if you (professionally) fitted a tyre, dot by valve, and it needed a bucket load of balancing weights (say, 100g), you would just balance it, rather than rotate the tyre?
:o

That's exactly what they did at Mercedes a few years ago ..... they put 105g of stick on weights on one spot. I didn't think to look as I picked the car up but phoned them later to tell them I would be bringing it back for them to do it again. The tech .... in his 50's couldn't see anything wrong ... infact he admitted that in the past he'd used 200g to balance a tyre. Not on my car I said. He was really pleased with himself on his return when he told me he'd only used 30g this time ..... like he should've done in the 1st place.

I took one of mine back a few years ago because he'd put one of these bleedin great lumps of lead on the outside rim. I made him put a stick on one on.

The other problem with clip on weights is that they damage the paint either side of the rim and gives salt & sh1te somewhere to sit while it eats its way through the paint & into the alloy. Fortunately lots of rims these days don't have that lip anymore on the outside edge ... though they do on the inner edge
-
Yeah thing is though I’ve had these tyres on and off a few times and rebalanced a few times so I’m thinking that perhaps the wheel repair may be the way forward.
Or.
I may just slap my new tyres on.
Decisions. 😂😂😂

A forced wheel balacing machine will do this for you. One of its main advantages is accurate balancing with problematic rims. It basically finds the heaviest part of the rim / tyre, and then the tyre bead has to be broken and the tyre rotated on the rim to the indicated position for the optimum balance with the minimum of balance weights relative to the tyre / rim weights.
Bit then you need a forced wheel balancing machine, which most 'run o'mill' tyre places haven't got....

Thanks Jonny.
I think the plan is to fit new tyres and see if I can mess around with the balancing. If not I’ll whip them off and get them rounded by the welding place
