Do any of you know which type of tires they use in real life, to set the fastest times on the Ring? I use sports soft when I go for a time there.... But that's also because I only go for a 1 lap time, where I guess in real life, they have a warm up lap before setting the time on sports hard!? Just trying to find the accurate simulation with the correct tires.
I think they use mostly tires equal to GT5 Comfort Soft.
But...some manufacturers might equip the car with some softer compound and dedicate it as "road legal tires", you know what I mean. In this case ( Nissan GT-R????) GT5 Sport Hard oe Med will match.
I think in game if you know Nurb well enough, you must set a faster lap time on GT5 tires equal to IRL. No fear.
Plus, its very important sometimes to watch video, if available to hear and see how they drive in real life.
For example, real life lap time of AUDI R8 4,2 is 8:01.90. I tried same car on Comfort Medium and my lap time was 7:54.933 (legit of course). I felt enough control, no fly-by through corners, consistent, fast driving. Not on its limit yet.
Another car, Nissan 350Z. Real time 8:26. I did it on Comfort Mediums at 8:25.999. Hard to reach the target IRL time, tires were squealing most of a time. I dont think they match real tires, Comfort Soft is OK.
One more car, SLS AMG. Real time is 7:40. I did on Comfort Soft 7:36.325. Good control, not on a limit yet.
The last two cars I tried are Toyota GT86 and Camaro SS '10.
Real times are 9:09 for GT86 and 8:20 for Camaro. I did 8:58.279 on GT86 (Comfort Hard tires) and 8:10.504 on Camaro ( Comfort Medium).
Its important to remember that IRL they use 20600 m length track which is 200 meters shorter than in game.
My tool is G 27, racing rig, I use NO assists, ABS OFF. Gear manual. I make 5 laps normally for each car. All times are legit. Cars are NOT broken in neither oil changed. Stock from dealer ship. All tests were done in ARCADE mode - Time Trial - Grip Real. Dry conditions, Day time change - 30. I am posting it here as an answer on your question, NOT a time trial leaderboard. My purpose is to find better matching tires in GT5 to real life.
From my observations, when I tried HONDA NSX-R to beat Motoharu "Gan-san" Kurosa lap time in 2002 which is 7:56 I could barely manage to finish 20800 Nurb layout in same time on Comfort Softs. Tires were squealing like a hell, car sliding through corners which was UNREALISTIC. On video I didnt see that real car was doing like that.
So, in conclusion I would like to say that GT5 Comfort tires are all over equal to best road legal tires in real life and for me its just pleasure to reproduce same lap time on same car which is used for Nurb time attack whatever that car would be. Plus, I try to drive like they do, NO power sliding on SPEED 250 KPH, NO 2nd gear after 5th for trial braking, just as similar as possible.
PEACE!
