Based on my past experience, when changing 4 tyres at 1 go, this shop usually quote the price inclusive of balancing, alignment & new rubber valve for each new tyre.
However, my car didn't need alignment this time after test drive. Partly because last balancing & alignment was done not long ago (less than 1k km), and I use back my own metal valve.
I know many tyre shops use the following technic to attract customer at borderline of dishonest way:
1. Very cheap tyre with hidden cost. Cut our throat at balancing / alignment / etc.
2. Must adjust chamber or else can't do alignment properly. In most cases, this is bullshit.

But this shop is not 1 of them, at least in my opinion for so many years. If you're really keen to change this month (since price may fluctuates monthly), I can help you to find out the nett price. You may PM me your tyre specification and other services you want to include.
Mind sharing this shop? I'm no tyre expert but looking to change tyres for my old Honda City 2006. Tyre specs 185/55R15. Other than XM2+ is there a comparable cheaper brand?
