Let's say I like the car selection in rFactor 2, but I feel like the tires have too little forward and lateral grip in all situations, which prevents me from enjoying them. Let's say some other cars, ZR1, ISF3, have tires that convey grip better and provide better feedback about sliding, deformation and such. Let's say it would be possible to use these different tires on the Formula Renault, Nissan GTR, and others, to make the ISI cars worth driving. Would the force feedback lightness still be a problem then? What would be necessary to switch tires around like that?
