Never heard of them.
It appears they are part of a stock company’s portfolio rather than a brick and mortar operation.
From their Site: “FixGo is an integrated online and offline platform for automotive service…”

Always worth to shop prices, but they likely source stock from a variety of distributors. The network for an installation shop might be scattered and then again finding a decent and careful tire shop isn’t always easy.
I know of a local independent tire shop that pretty much does the same shopping and stock is dependent on a couple distributors, low overhead and labor keeps pricing down but the drawback is like ‘day-old’ bread….not necessarily freshest dated or current tires varieties.

For the record, long time tried and true TireRack is a PCA event sponsor and probably the business model of the FixGo service.
