Hi, I just recently purchased an 06 2CS with snow tires (I'm in Canada). The snows, Pirelli's, are actually very smooth riding. As I have a bad back, I'm a little concerned about summer tire size choices, although I'm leaning toward Michelin Pilot Super Sports. The stock rears are 295/30 ZR 19. I'm wondering if I could go with 305/35 or 305/40 ZR 19's? I figure the larger side wall will provide a smoother ride.

If anyone has any ideas or suggestions, I'd very much appreciate it!

Thank you,

John

Something to keep in mind is ratios. You want to maintain overall dimensions as the stock tire and wheel. If you don't care about performance of ABS and traction control, go with looks

I know 18s on more rubber = wayyy smoother ride. Louder, but smoother.

Yes in theory larger sidewall will smoooooth out the ride.
If you're in Toronto. There are no roads not under construction.
Any piece of hot pavement will the hacked before cooled.
Your not going to notice any difference between a 35 and 40 series tire.
As above fitment will be the issue. Too large a tire? The jarring of the rubber hitting your fender will negate the smother ride.
I vote for the Super sport's. Order them now, before the rest of the country wakes up from hibernation.

I was actually more interested in the difference between a 30 and 35 size, but if 35 to 40 would make little difference, I'm guessing 30 to 35 wouldn't either?

The car actually came with a fairly new pair of 305/30 ZR19's, Michelin SS's (approximately 500 miles on them). Tragically, I found a spike in the center of one of the tires and am not sure how to deal with this, whether to contact Michelin and see if they will do anything for me or just get it patched? It is a terrible shame.

P.s. I called Michelin and a puncture is considered a road hazard; translation, I'm SOL.

I good tire shop will fix that puncture most likely. Stay off it and get it in for repair. Porsche dealer is going to tell you to replace the tire, as they don't seem to condone any repair of anything. Replace replace replace. Also followed by full retail full retail full retail.
Dr. J - Make sure your air compressor works, check your slime supply. I also carry a plug kit in all my cars, with a jack 2x4 and wheel wrench.
Preparedness = never needing it

Dr.J

Thanks, Big smoke, will heed your advice. I called the tire shop, said they'll have a look.
My air compressor???

thanks!

No response to my Canada question.
Are you in toronto? I would have some shop suggestions.
Outside of Toronto? perhaps someone else.

I'm down south, across the lake in the Niagara Peninsula, half way between the Falls and Buffalo, Welland!

I used to replace tires but now I plug my own.

Can't get anyone to repair high performance tires.

I have not had a plug fail, knock on wood.
