Chicagoland: Tire balancing???

[Paul Workman]

I got the Z out today...Dry, almost warm, sunny...WooHoo!!!

It never occured to me before my little run today, but I suppose it is important to mention to whomever balances our tires they need to be balanced for high speed, no? Let's imagine (hypothetically speaking...of course!) a tire vibration is noticed at...oh...145+mph (let's say). It might occur to me that balancing tires for granny's Buick is one thing, but balancing them for a "Z" is altogether something else - requiring some special attention for high speed tires no? Can anybody shed some light on tire balancing for performance cars? Anything special required that a pimply-faced tire changing youngster with too many hormones needs to know to do it right?

Thanks in advance. Oh! My new GY -D3s came from Discount Tire. Would they know what I need and could do it (since I paid for lifetime balancing, etc)?

TIA,

P.
