Maruti Suzuki India — spare wheel dimension

Address:

Sangli, Maharashtra, 416414

As per major concern over the change size of spare wheel. I recently brought the baleno aplha model and while checked i got to know that spare wheel is in smaller size. I mentioned it to car dealer he started giving absurd reason, but after some days when i was travelling one of tyre got punctured and i was in remote place so there was no shop to repair, when i tried to put on spare wheel it was not right placed due to change in sizes.
Not happy with spare wheel.
