Tyre punctures can be fixed at any roadside stall for Rs 100. The 450 uses a tubeless tyre so you are not going to get stranded with a completely flat tyre.
Hell, I drove for 2 weeks with a nail in my rear wheel until the Air filling guy at a Shell Petrol bunk pointed it out.
On a side note, looks like there is a nail mafia in the KR Puram - Whitefield stretch. Had 3 nail/screw punctures in the last 4-5 weeks and all are coincidentally on the rear tyre.
