I believe that that's the reason right there.yes you can road force used tires, all it is is a more detailed balancing
a more true balancing that it allows to see exactly how the entire assembly will act on the road. but with used tires it will have it's limits/ I mean the process can be done but the outcome is more exact on new tires thats all.
Please explain.Correct Thats why if its a hunter road force touch they can do a match 180 procedure to ensure the runout reads out properly.
So this process is when they match the high point of the tire with the low point of the wheel. now this is something ive seen done on new tires. That being said it may be more difficult on used tires, but it may also be possible.Please explain.
