You can do and think what ever you choose to. Myself, I have every tire, for everything Speed Blanced, at no extra charge.
Because where we buy our tires, Tires, Mounting and Balancing and install is all in the price of the tire sale.
Myself, I wouldn't ever put on any tire wihtout it being Speed Balanced. A Bubble Blance Tire only does so much. A speed Balance shows what the tire really does at different speeds.
Even if it wasn't Free, I would still pay to have it done, as I have seen to many tires that cause a lot of viberations over the years, and way to many OZ's of weights put on them.
The same thing goes, if very much weight is needed, I won't except the tires, Period.
We want every tire we by checked and Speed Balanced, no darn Bubble Balance for us. We also get the Max tire life out of all out tires. Good Luck. Happy Travels. Dan & Jill
