yup, steering wheel on mta will not work, cuz u have lot of corners and curbs, and u need fast reaction to do full turn, and also even if u will use steering wheel, your full turn will be limited by script similary to keyboard and gamepad, w/o mods [and mods dont work with mta] steering wheel is useless. U probably wanted to set +10 grip tires and turn like on -10 tires or even better XD
