Nice car but WORST tyres

I bought the car in 2016 . Toyota staff is good when the are selling the car. But at the time of car service they always try to increase the bill as much they can but you have to be care full. But the BIGEST PROBLEM in this car is its 17” wheel . I have to change 7 tyres in 3 years. They are so delcate that i have drive so carefully on the roads. A small khada can burst your tyre on the road.
