Unfit for Purpose?

[parapaul]

In a nutshell - I bought some aftermarket alloys for his car, from a (locally) well-known and respected shop. The shop offered tyres fitted at a sensible price so I went for the whole lot. The guy in the shop asked specifically what car the wheels would be going on, and then subbed out the fitting to a local mobile fitter, with whom he presumably has an agreement.

It turns out, several thousand miles later that although the tyres are the right size, they are well below the manufacturer's OE spec - the load/speed index is 88W, when it should be 91Y. The tyres are otherwise fine, but I'm now concerened that if anything should happen, the insurers would not pay as they're effectively sub-standard. I know the speed index is a non-issue really, but I'm a little concerned about the load index.

I'm trying to scrape together the money to change all 4 tyres, but I thought I'd ask if it was worth complaining to the shop, or the tyre fitter, or both in the hope of some compensation?

Did you specify exactly which tyres you wanted (including speed / load ratings) or did you leave this to the discretion of the shop?

The shop specifically asked what car the wheels were going on - I clarified the wheel and tyre sizes but never even thought to ask about load ratings...

Have you told the insurance company about the wheels?

Wheels, yes. Sub-standard tyres... not yet...

Whether the seller is reputable or professional enough is another question!

And should I take it up with the shop or the tyre fitter?
