Tire stores in between Boston and Southern NH area

I need to buy winter tires for my 2016 V6 Mustang with 18"s in the next few months. Does anyone have suggestions on places to go? Town Fair tire seems to be cheaper than Sullivans, but I worry about the quality of these chain stores. Are there any local places that would be better?

I've purchased tires from my local Town Fair Tire store. I ordered MSS when I had my 06 GTO. They matched Tirerack.com pricing and we're extra careful mounting them on my wheels.

I purchased tires from town fair for my sons civic and they were great I got hime new rims and toyo tires for 700.00 and he loved them
