The services of a shop should be handled by the application, not by the user. If the application is correctly written it should know that even if the user writes "tire" it should search for "tyres" tags. Moreover, I think it's very wrong to have a tag working only for a state, while the rest of the world agrees on another tag. I understand that "tire" is a possible tag, but why should this tag not follow https://wiki.openstreetmap.org/wiki/Any_tags_you_like#How_to_name_new_tags (which also suggest that new tags should be in British English)? "Tire" is US-centric and this can lead not only to mistakes but also to some engine not looking for these places since the more widespread tag is "tyre".
