Context: Up until now, I had only one set of rims and 2 sets of tires (summer/winter). Every season change, I went to a shop to install the tires on the same rims. This always included balancing.
This winter, I've purchased a second set of rims with a new set of winter tires. I'm now about to switch back to the summer tires. So, changing would be: take the whole wheels with the winter tires out and put back the other whole wheels with summer tires.
Question: Does the shop need to do the balancing on the summer wheels again before installing them? It was done when the tires were installed on the rim 12 months ago.
- summer rims are aluminum (winter are steel).
- over the winter (aprox 5 months), I've kept the wheels on a rack looking like this
