Stock Tires

I just fitted my '71 Renault R8 with R888 semi-slicks and they do feel somewhere between S3 and R1. So I think that S1 and S2 are vey accurate for the sport cars or even aftermarket high performance tires (not semi-slicks, but more like the BF Goodrich KD), while the n tires would be really thin and cheap tires. I believe that R1 tires are hard racing slicks, R2 are soft racing slicks and R3 some kind of unimaginable supersoft ultrasticky slicks.
 
Based on my own driving experience, reading car reviews, and comparing in game and real life lap times, I say N tires are the way to go. S tires are way to grippy to simulate anything lower than street legal R compund tires like Pilot Sport Cups. The best performing cars/tires get about 1 g through the corners, and can you break traction pretty easily when you want to. My estimate it this:

Supercars/fast sports cars (Viper, F430, Evo, M3) get N3's
Sports Cars (RX-8, Integra) get N2's
Economy Cars get N1's

The tires themselves aren't dead on accurate (especially in longitudinal grip) and don't let the induvidual performance of each car come through because the tire is the only thing that determines max lateral grip (so a Mini will hold as many g's as a Viper with N3's which is ridiculous), but it's the best we've got right now.

What is the survey data you're using? If it's a survey of people's opinions I'm not sure you can reliably convert it directly to grip. The survey numbers will have people's expectations, biases and the handling of the cars they are fitted to mixed in with the actual, objective tyre performance.

As a contrived example, people driving an Evo X would be likely to rate tyre A higher than people using tyre A on a Volvo, because the Evo X makes such incredible use of the available grip. If tyre A is mostly fitted to Evos and tyre B mostly fitted to Volvos then tyre A would have a higher survey rating, even if tyre B actually performed better.

Psychology plays a role too, a Pirelli or Bridgestone would likely get a higher rating than an identically performing Hankook tyre.

The survey im using just goes off the tire, EX Grip level, conering stability, steering response. So for example tire A is a S1 tire. Tire A comes stock with the Evo X and the Volvo, therfore the Evo X and the Volvo comes stock with S1. Now this dosent mean the cars will still run the same times on the track etc. it just means both cars have nice grippy tires. the way the manufacture build the car still plays the biggest role. If the manufacures had more money to throw out im sure they would put better tires on their cars. i think of it like this i rather upgrade the tires to improve my cars handling then have to deal with a poorly built car with great tires.

Hey buddy nice tire ratings i would like to share mine with you so we can compare and contrast and try to work out the best way to get the real feeling of the stock car.

ViperGTS stock tire are Michelin Pilot Sport PS2 got a rating of 92 cornering stability, tire grip 94 and steering response 92. it averges out to a 92 rating tire. in my tire rating chart that would be a S1 tire which is prob the best tire your going to get with a stock car. lets do the F430

F430 Stock tire Bridgestone RE050A (CS)88, (TG)89, (SR)88 average 88. So its a 88 tire grade in my tire survey which are N3, however you could also get Goodyear Eagle F1 GS-D3 run on flats which come out to be N3. You could also get Michelin Pilot Sport PS2 which got (CS)92, (TG)94, (SR)92 which comes out with a 92 average (i would get this tire package deal!!! with the
F430)

The Evo IV comes with Yokohoma Advan A046 this tire got straight 94 across knowing the tire got a 94 tire rating these tires would be rated as S1

The BMW M3 comes with Michelin Pilot Sport PS2 you should know the story about these tires S1

Both the RX-8 and Integra R come with BridgeStone RE040 which got a rating of (CS)76, (TG)80, (SR)77 which comes out to a 77 which barely made N2 tires. i agree with economy cars being N1.

Yeah, our methods do seem to correlate pretty closely. I do like how you've got it down to number though. Mine is a bit more subjective.

Though the reason I really hesitate to put S tires on car is because of the apparent skid pad number they can get. I've gone to Daytona in game on the back straight and used the wide area as a skidpad. I think even S1's pull about 1.2g, which is .05 g higher than the last skidpad rating I saw for an SCCA Speed GT race car (1.15g). The highest skidpad I've seen for a road legal car likely to be in GT was the Viper ACR at 1.12g, though it's normally at 1.08. The only car in GT5P that would have similar tires is the F430 (optional PZero Corsa's), and they only shave about 1-3 seconds off a 1-2.5 min laptime. In GT, I can get a 5 second or more difference between N3's and S1's. The combined braking and cornering advantage of S is huge.

yea i def agree with you. i was driving with N2/N3 tires and then jumped to S1tires and they are way to sticky for stock tires IMO. breaking and conering with this tire is way to good! im going to try to work out some new numbers because i really think S tires are way to grippy for stock cars
