OK. Tried the contact "phone numbers". First off, there is no such combination of phone numbers in the US.
Secondly, the street address doesn't exist or isn't indentified to anything like Prof-tire.
Thirdly, tires isn't spelled tyres in the US. That is a UK spelling.
So take your pick of what the issue is. Most likely this is a VERY old link that came up on the Internet but the inconsistencies associated with it tend to suggest that it is a scam listing.
True, the link comes up as working on the 'net, but it looks like a wild goose chase?
That's all that I can come up with. It looks like a 20 or 30 year old listing according to the price and those tires haven't been available in 15 inch diameters in about that long of a period of time.
