I found when I owned GTI's that it's not worth rotating unless you get all 4 wheels rebalanced. That's probably the cost of one new tire each time, so from a time and money standpoint is it worth it? I was going to rotate my R's until I discovered the rear wheels kick in more than I thought. The rear's are only a couple of 32nd's difference than the fronts now so I'll just get 4 new tires when the fronts wear down. I want to try the Pilot Sport 4S' anyway. Besides, if you were looking for a car that gets a lot of miles to a set of tires, you should have bought a Prius.
hehehehe I have a Prius in the family....
Anyway, it's not about getting A LOT of miles out of the stock tires. But if I can get more miles out of them with little or zero expense, I'd like to know that.
As you point out, it's all in the details--and the math.
So pray tell, why would you have to rebalance the wheels just because you're moving them from one position to another? A balanced wheel is a balanced wheel, right? It almost sounds like you're questioning whether they remain balanced even when just moving them from the balancing machine to the car.
And if they need rebalanced when moving from one position to another, wouldn't they also need rebalanced even if you don't rotate them? Aren't you saying that as you use them, they become unbalanced even staying on the car?
What am I missing?
