based on my experience last week i went for some tire tests. i found 8 different tires available, 3 gt, 2 ngt and 1 for the elise and one for the gt3cup and 1 for the bmw. i focused myself to the non gt tires since the gt tire is quite huge and this is the reason for the cold temperatures. surprisly, the ngt and the other brands are less stable in bends, this means, the car is wobbling a lot. this requires a complete new driving style since balancing the car with the throttle wont work any longer. especially in esses the rear tends to oversteer and if i want to put some more load on the rear with applying some throttle the oversteer becomes very fast a powersteer. the tires for the elise and for the bmw seems not really usefull for my current car. even after adjusting the gear ratios to the new diameter, the car was unpredictable and unstable. the ngt tires are not very different from this so i went out for some laps on the gt3cup tires. after struggeling a little with the pressure i learnded that i need some changes on the setup as well. with some more strength on the swaybars, more pressure for the tires and slightly stronger dampers on the rear, the car is now handy, even if it is not as easy to drive as on the gt tires. but the grip has increased and the powerslides are reduced to an acceptable happening.
