The size is the search. «205 55 R16» is not a word but a buying intent, and treating each common size as its own page captures demand nobody else serves.
Urgency is written into the query. «Today», «now» and «open» get typed by somebody with a nail in a tyre, and opening hours with free slots beat any price comparison.
The legal requirement brings two waves a year. The moment the first cold snap is announced an entire region types the same thing, and the page has to exist in October, not December.
Brand against budget is two different worlds. Somebody typing «cheap tyres» and somebody typing «Michelin offer» are two customers, and one page loses both.
Storage gets searched without anybody knowing the word for it. «Where do I keep my summer tyres» is the real phrasing, and writing it down turns one appointment a year into two.
The radius is short. Tyres are bought where you can drive without losing a day, and the name of the district pulls harder than the name of the region.
