Well on a lighter note, don't be so concerned about high speeds, first complete initial 1000km then visit any dealership near by ask them to check alignment and balance the wheels, after that go to higher speeds, let see if you are satisfied or not.. If not, then your only option is to change tyres..
By the my car has clocked 2100km so far.. Haven't tried it above 110km/h.. So don't be so concerned, take it easy.. It's Corolla bro not reborn..
