Halfords fitted a different load rating to what I ordered

[oilslick]

I ordered a couple of rear tyres for my car - Avon ZV7 (205/55 R16 91V) - after finding a large screw embedded in the edge of one of the old tyres.

I didn't think to check what had been fitted when the guy came, but looking at them today, I notice they're extra load with a rating of 94V.

I realise this is perfectly fine in terms of them being over rather than under specced, but can I expect to notice any difference while I'm driving? It's a Toyota Corolla hybrid so hardly a car that will be driven at the ragged edge

I'm wondering whether it's worth querying or not and thought I'd seek some opinions more educated than mine before I spoke to Halfords.

Just don’t.

As long as it is the same or higher than is needed, it's perfectly fine.

There is the answer to your question.

No, don't bother.

Id agree with the above.

But on a side note would the extra load rating make a differance to mpg? Would it be slightly heavier or have more rolling resistance?

I recall an announcement from Michelin a few years ago saying they were cutting down on the all the different speed and loading ratings for the same size and model of their tyres as they were often the same tyre underneath, just with different numbers and letters stamped on the side.

I also recall a tyre retailer on various mx-5 forums saying that extra load tyres were essentially about the tyre being able to cope with the higher air pressures needed to support the extra load, rather than any increase in stiffness of the sidewall having anything more than a marginal effect, as you can still squash the sidewall between your fingers, which isn't going to be much help when you have many hundreds of kg pressing down on each tyre.

Thanks for the feedback chaps, will leave this one alone

No.
