I am stealing the starting info here from my local boards, but please feel free to add any additional posts, using the layout below. Please avoid random banter/discussion. Thanks.
SUMMER:
BFG G-Force KDW-2 Ultra High Performance
Per tiresmoker:
Pros: Neat tread pattern. This tire does well on wet conditions under full tread life up to half tread life. It has a softer sidewall (privided you don't get a low profile reinforced) so it is easier to mount as well. Treadwear is pretty good.
Cons: This tire is anything but Ultra High Performance. In track and autocross conditions the tire get hot and greasy extremely quick, also it takes quite some time for the tire to cool down. Normal every day commutes can become tiresome as well as this tire is quite loud. Once you get down to half tread life the tire does not channel water that well and can result in some slippage on wet roads.
Falken Azenis RT 615's Max Performance
Per tiresmoker:
Pros: Quite tire. Extremely stiff sidewall so lower pressures can be run. Great for autocross and track applications. You can feel the limits of these tires and when they are on the verge of slipping they don't just "let go" They do well with high temperatures and don't overheat as easily and get greasy. Cost is pretty decent as well for the tire you get.
Cons: Short treadlife if use as a daily driver. Large surface area of treadblocks also doesn't resist rain as well once 30% or more tread has been used. Very Very VERY bad in the snow
Yokohama ADVAN Neova AD07 Extreme Perfomance
Per tiresmoker:
Pros: Decent tire in the rain throughout treadlife. If you can keep this tire cool (autocrosses and track days) it does alright in performance situations. I only note that in "pros" because it does do "ok" when ambient temperatures do not excede 60 degrees F.
Cons: WAY overpriced for the tire you get, in fact too damn much. Wears extremely quick so do not use as a daily driver. Marginal rating at best for use at autocross and track events. This tire overheats quickly and becomes greasy. It does cool down quickly, but the cool down time does not offset the fact that the tire gets too hot too quick. Also, this tire will not let you know when grip is lost untill it's too late. The tire heats up then just lets go, there is no middle ground where you can start to feel the tires grip diminishing. As these tires wear they get EXTREMELY loud. In fact, that is the only thing "extreme" about these tires. Soft sidewalls as well To put it mildly, Yokohama should be shot for charging this much for a tire that does so little.
General Exclaim Ultra High Performance
Per focuson03:
Pros: Awesome tread life. Good hydroplaning resistance. Very predictable. Cheap for what they are.
Cons: Should be classified as High performance, not Ultra High Performance. Sidewalls are VERY soft and leave for a lot of flex. NOT meant for auto-x! Tread compound is fairly hard. Any temp below 40 and these are ROCKS. They do not like to even see the lightest of snowfalls.
Nitto Neo Gen Ultra High Performance
Per lildisco:
Pros: Awesome tire and tread life even if you Auto-X or Road Race with. Lasted about 10 Auto-X's and 2-3 Road Course plus regular summer driving. Plus they're relatively Cheap!
Cons: When they go....they go. They don't funnel water too well below 40% tread life. If you do Auto-X or Road Race you have to jack up the tire pressure to lessen roll-over.
Per CrashTECH:
Pros: They were cheap (if I had bought them new, I got them with ~ 300 miles on them). They were sticky when they had decent amounts of tread. They lasted quite a while for me under spirited (no track time after the first 300 miles, lots of harder-than-necessary starts and cornering on the street) driving. I thought it was pretty good for having the 280 tread wear rating.
Cons: When they wear it is a fair bit easier to get squirrely on wet roads. That said I have never had too much trouble with them in the rain / wet conditions. While it was easier to get the back end out it wasn't something that happened without my intending to do it.
Other thoughts: I didn't keep good track of how many miles I put on them but they have somewhere in the range of ~20k on then now. I may try to get another 5k on them but I am not sure that will be possible (read: safe). I could get two summers out of them if I purchased them again. I am currently shopping to see what is available to replace these on my summer wheels. Might buy again might not. My experience hasn't made me feel anything strongly one way or the other about them.
Yokohama S.Drives Ultra High Performance
Per lildisco:
Pros: Nice Tread Design. Very predictable tire. Funnels water fairly well.
Cons:Really haven't found any yet. For it's wear rating, it falls right in where it should be
Bridgestone RE-01R Ultra High Performance
Per sl1200:
Pros: Excellent dry grip through most of their life. there's a good reason this was pretty much the ST autoX tire. The held up well at track speeds as well. Surprisingly good wet grip as well given the minimal grooving. Also quite compliant for such an aggressive tire, so they are comfortable on the road.
Cons: Tread life. expect no more than 10K miles. Also they are noisy below about 45k miles thanks to the aforementioned minimal grooving. They are also farking expensive unless you find them on closeout.
Continental ContiSport Contact Max Performance Summer
Per lildisco:
Pros: N/A
Cons: Cheaply made and way over-priced HORRIBLE tire. Screamed at anything harder than a slow turn. Tires lasted less than 6 months with 50% tread life and barely driven. Don't purchase these over-priced POS tires.
OEM Potenza RE050A (max performance)
Per wannabe:
Pros: Good grip on dry pavement
Cons: Crappy tread life, expensive($225/ea), not all that amazing grip, esp on wet or light snow.
Kumho SPT Ultra High Performance
Per wannabe:
Pros: Pretty good grip on both wet and dry pavement. Cheap. Treadwear seems pretty good for this price level.
Cons: Got a bubble in one only 500 miles after purchase.
Per Fez:
Pros: Cheap. Great daily driver. Very good in the rain.
Cons: Soft sidewall, would prefer higher load rating for ms6. Wear out pretty quickly on the track and need constant rotation.
Other thoughts: I would highly recommend these for someone who doesn't track the car much and uses it as a daily driver. Otherwise - there are better options.
