I'm very much aware of not just buying a tire on looks, thanks for looking out, though.

The F1's on the car right now grip well, but they're noisy as heck, tramline, and ride very rough. I know I'm not driving a Lexus, but there's some better options out there like the Michelin PS2's.
Hi Mark. We haven't talked in a while, so here goes...Hope you don't mind.
According to tire manufacturers....Serrated (ribbed) sidewalled tires are supposed to evoke the emotions/look of: sleekness and performance.
Yeah, right! Like you, to me they evoke the emotional rollercoaster of to "dress or not to dress"---to shine or not to shine, so to speak. It has been my experience though, that, often, due to the
gleam from clean chrome wheels, such as you always have,
reflecting off these serrations on the sidewalls, that even undressed, these tires will emit a little shine.
IMO...If you don't dress these tires on your Corvette:
-The blooming (browning) that's caused by the tire manufactures' inclusion of antiozonants during the manufacturing process, will be less noticable on serrated sidewalled tires and should be easily washed away during your cleaning cycle; and, by the time these tires have reached the end of their life cycle, these antiozonants (being somewhat less as a presence because of the aspect ratio of low-profile tires) should be depleted anyway.
-You may have more brake dust creeping into those ribbed areas...but again, removal should be a breeze due to your cleaning cycles.
While the width (contact patch) is a factor in tramlining/rough-riding with these low-profile tires, the strength(#of plys)/size of the sidewall/shoulder block also comes into play. As you know, run-flats have a harder/stronger sidewall/shoulder block vs. the non run-flats. [How much stronger, though?]. Some tires with these wide contact patch areas tramline more than others...they'll all tramline more as the tread wears.
As far as the noisiness...In my case, due to the exhaust system, I would'nt hear the "tire-noisiness" on mine even if the tires were "big ol' knobby off-road ones". But that's just me.

{If someone is close enough to hear my tire noise, then it's either my fault, or the speedometer needs recalibrated}
I know that tire safety, and not the costs associated with having ones mind-at ease, is uppermost in your mind.....Since Michelin PS2's, (and other tire manufacturers), come in either run-flat or non run-flat...Which ones are you leaning towards? My preferrence leans towards tires with the (Y) speed rating...and I don't want to carry around a "fix-a-flat" kit.
Note: I know, that you already know, all the above...I just enjoy having a good, concise, gab-session at times; that, and using a little bandwidth. LOL
Nice talking with you again!
Bob
