On a other note, the Indy 500s are a great tire. 90% of the grip of the Pilot Sports for a fraction of the price.
Owner reviews for tires
On my daily car (e39 BMW) I use Michelin CrossClimate tires, because it doesn't get realy hot or really snowy here (North-Western Europe). As for all seasons, they are considered pretty good.
So I came to event day on my normal Dunlop SP Sport Maxx tyres. In practice, I found that on the R-spec I could do an 89 second lap, but consistently run at 92 seconds (I could do consecutive 90 second laps, but brakes would become the weak link after about 4 consecutive laps). On the street tyres I could do a 93 second lap, but due to brakes again, nominated at 95 second lap.
But I put some pilot sport 4s on the sti for the first time this year and... What can you say, it's a completely different car. For handling, it shares absolutely nothing in common with the same car on economy tires.
I like the Michelin Pilot Sport 4S. It's a well-rounded performance tire. Track ready, great handling wet and dry, comfortable on the road, 30k mi treadlife.
I went with General Altimax RT-43's (H speed versions). Are they as good as the Michelins they replaced feeling wise? No. But they were affordable, have been lasting quite nicely in terms of tread life, and have been working out just fine for my uses.
Just picked up some dirt cheap 26" tendrils to replace the nobbys on my stumpjumper commuter. Hope they do well with glass riddled roads, but honestly at $10 a pop it's not a big deal if they don't.
Kumho makes solid tires. I had a set of the PA31 and they did well.
Ran them on my S60 back in the day, pretty much exactly what I expected for the price. Only complaint was tread wear, but for a commuting daily they will give you plenty of life.
I would stay away from the Pilot Sport A/S 3+. I put a pair on the back of my 15 E550 Coup. 4,000 miles and they were bald.
