Good advice from other posts above... if it's noticeable enough to bother you, I would ask the dealer do a road-force balance.
Not long after delivery I had similar problem w/my S coupe's 19" Pirelli P-Zero fronts ...front wheel vibration between 65 - 75mph, disappeared at 80+. At only 800 miles I had not hit any bad potholes yet..... the dealer was able to cure the vibration with a full road-force balance (@ $0 cost-- dealer said because of low miles; they did the re-balance in an hour while I sat in their showroom CGT pretending to drive it
).
They fixed the vibration by deflating and re-positioning both front tires on the wheels as the Hunter machine dictates. A lot of technical background on road-force balance> Here

TSB 4075 (07/05) points to creaking in the front suspension, and calls for spring replacement.

No vibration to 180 mph with Bridgestones,--ever. No flat-spotting either,--but then, I actually drive my Porsche. (Approaching 10,000 miles). Perhaps it's the roads.

My Bridgestone's are very smooth at high speed too; it's the first drive in the a.m. or after the car has sat overnight that the steering wheel shimmies from side to side until the tires are fully warmed...never had that problem with the Pilot's even on my last 997S.

I'll third the motion on the Bridgestones . After owning 2 sets of PS-2 (about 30,000 miles when I was ready for 3rd set) I decided to try a diffrent brand . I was told of many negative isues in previous forums but I already owned them and decided to try. I have had 0 problems so far and I am very satisfied. Oh I almost forgot !!! Bridgestones are about $600.00 cheaper for a set.

Hearing as many kudos for the Bridgestones as for the PS2s. I'm very happy with my Pirellis, but when they need replacing I might be tempted to try something different. My 993 used to have Bridgestone S02s and they were great. What B'stones are you guys wearing on the 997?
