Sport techno tire choices
Hi everyone,
I have a few questions regarding tire choices for the Sport techno wheels. I've numbered them to make them easier to answer.
I'm considering the sport techno wheels for my C2S (especially if I can get them painted). However, since they are an unusual size (305), it seems the tire choices are rather limited compared to the standard wheels (295), at least when looking at tirerack.com. Most notably, it seems the Michelin Pilot Super Sports are not available at the wider size. My general impression is that compared to the stock P Zero's, the Super Sports are the superior tires (in terms of perfomance, ride quality, and tread wear) and cheaper as well.

Price to replace all 4 tires for the Sport techno's:
P Zero
Front: $315 x 2 = $630
Rear: $595 x 2 = $1190
Total: $1820
Price to replace all 4 tires for the standard sized (i.e. Carrera S) wheels:
With P Zero's: $1758
With Super Sports: $1284
Price difference: $1820 - $1284 = $536 saved by using the Super Sports on the standard wheels vs P Zero's on the Sport techno's.
The other available tires at the 305 size are the Bridgestone RE070 ($572 each but seems to sacrifice wet performance) and S001 ($455 each).
1. Anyone know how good these two tires are?
I plan on using my car as a DD, with possibly occasional track use. I live in SoCal, so wet performance is still an issue, especially in the winter months. I don't plan on swapping out a separate set of tires just for the track.
2. Anyone with experience comparing the P Zero's to the Super Sports? 3. Will Michelin eventually offer the 305 size on the Super Sports?
4. I know this varies with usage, but how many miles do the stock P Zero's usually last before needing replacement, compared to the SS?
5. Bottom line is, will I be needing to replace the P Zero's a lot more frequently than the Super Sports, and is it worth it just to get the Sport techno's? The $536 difference per set multiplied several times might be a bit much, especially if the SS are superior tires...
I know this was a long and somewhat complicated post, but thanks!

I am also getting the Sport Techno's and my car will be Daily Driver. I live up in Vancouver where it rains all winter. My plan is to run out the Pirelli's (so to speak) then in a year or two upgrade to Michelin. I'm sure they will have some Michelin to size by then. With the C4S's coming with 305's on rears I'm sure there will be alternatives a year or so out.

I have the Sport Techno wheels with about 5000 miles (fair weather DD) and 5 track sessions on them. There is still half tread except on the rear tire's outer edges, so wear seems to be pretty good for a DD/track car. I assume Michelin will provide the 305 next season when I am in the market for replacement. As mentioned the C4 will help create demand for alternatives.

Can anyone post some pics please. If they are the same wheels as those on CDinSing's, then I really like them. Also, heard they were the lightest 20" wheels. Damon-do you know the different wheels weights and just how lighter these might be? Cheers.

According to Porsche website, Sport Techno wheels come fitted with the same size tires as all the other wheels. Yes they are 1/2" wider but that is well within the range of acceptable fit. Or am I missing something here? Techno wheels come with a special different size they aren't telling us about?

Sorry old chap, not following your jargon. 306's???
What I mean is, even looking at the C4S it is the same wheel and Porsche shows the same wheel dims and tire sizes 245/35 and 295/30 for both cars. So what is 306 and what am I missing???

Anyway I think I'll probably stick to the sport technos for my build for now since people seem to think Michelin will release the Super Sports in the near future. Hopefully they'll be available by the time I wear out the stock tires...

Where? Link please. Because this is what I've been seeing:
20-inch SportTechno wheel
Alloy wheel in distinctive 5 spoke design
GT Silver Metallic wheel center finish
Wheel center caps with colored Porsche Crest
Front Axle: 9 x 20 rims with 245/35 ZR 20 tires
Rear Axle: 11.5 x 20 rims with 295/30 ZR 20 tires
The Technical Section for the C2S lists the same tire sizes, while the Technical section for the C4S shows:
The S models are equipped with light-alloy 20-inch Carrera S wheels as standard. The visual effect is sporty and dynamic. The tires are slightly wider to cope with the increased power output of these models: 245/35 ZR 20 at the front, 295/30 ZR 20 at the rear. All-wheel-drive models have 305/30 ZR 20 tires at the rear.
Notice that while Porsche fits 295/30's on the Carrera and C2S, regardless of which wheel is optioned, they fit 305/30's on the rear of the C4S, again, regardless of which wheel is optioned.
Either size is well within the range that will fit both the wheel and fenders. Choose the one you prefer based on cost and performance.

Per the manager of my local Tire Rack, he said that his Michelin rep indicated that Michelin had no plans to N certify its SuperSport tire as long as it continues to make and sell its N rated Pilot series tires.

Yes, I got that off Porsche.com. It was a good catch because I learned they feel a wider rear tire more desirable on the 4S, even though its the same wheel as on the 2S. Probably simply that they know how much fatter the 4 guys like their rear ends, so gave them the fattest tires to go with. I mean, what good is a fat butt without thunder thighs to balance things out? Seriously, both sizes are within the range of ideal fitments, so get whatever turns you on.
