Have I damaged my wheels ?

Hello, I had my winter tyres mounted on aluminium wheels today. Car is Suzuki Swift 1.2 NZ. I asked the mechanic with how much torque he pulled the wheel bolts, he said 140Nm. When I came home I read in the operating instructions that Suzuki recommended a suit torque of 100Nm. I called the mechanic, described the situation and he offered me to make the wheels a little looser. I accepted, was back to the Me chaniker and the wheel screws wheel bolts he then screwed at my request on 110Nm. I know that I should read the operating instructions BEFORE the appointment, but yes… So I drove the car a total of about 20 km with the wheel scraper wheel bolts that were fixed at 140Nm. Did I maybe do a damage to the wheel because of this 20km drive ? I have to control the wheels in the next 50km a bit more. Thanks for help
