I took my friend's 2012 Civic to my local tire shop for a new set of tires. This car has steel wheels with 195/65-15 tires.
We decided on a set of Michelin Premier A/S tires.
I watched as the new tires were installed. One tire assembly required 0 weight. Two tire assemblies called for 0.50 oz/each. One tire assembly required 1.25 oz.
The balancer used was a Hunter GSP9200 with the smartweight feature.
I understand that the amount of weight needed is not a big deal, and the overall road force value is much more important.
But it still makes me curious - how is it possible for a tire/wheel assembly to be within spec with no weight needed?
