Tire Price seems fairly in-expensive...
Just going off the cuff

$420 per tire
Generall about $40 mount/balance from my PREFERRED INDY
X2
Add another $160 or so for a alignment

Not sure where the #'s play or how OCD you are, but Redline over in Greenbrook is my go to shop for tire/wheel services. Might cost you a bit more than Mavis.

But then again, Mavis has got some killer pricing on tires. I only know this as family came over and got one of their sidewall punctured. Tire size was one of those usual 20" not in stock sizes. They decided to do all replace all 4 corners and Mavis cost per tires was $40 less PER tire than than even Tirerack, which I found surprising.
