What they did

Costco quoted $2,199.96 (Australian dollars) for four Michelin tires for a Model Y. Grok Bot found the tire size in old Tesla order emails, priced 47 shops across four chains and found the same four fitted for $1,856 in a 25%-off sale, without a single phone call.

How it went

The cheapest fitted price for the exact tires, with sale end dates and the fine print (no shop included a wheel alignment, so budget about $130 to $180 for one).

Worth knowing

  • Single user report (a short thread with a screenshot). Prices are Australian dollars and the sale he found ended on the 17th, so your numbers will differ. Always confirm the size on the tire sidewall before you buy.

Prompt

Cleaned version rewritten from the source — not a direct quote.

I need [4] new [brand/model] tires for my [car]. First find my tire size from my old order or service emails, and remind me to double-check it on the sidewall. Then compare the fitted price for those exact tires at shops and chains near [my city], including current sales, against my quote of [store and price]. Flag fine print like wheel alignment not included or fitting only in another state. Show me the top 3 with the total fitted price and a link. Don't book or pay for anything without asking me.
