van tyre on a car

Wig

.... Avon T 86 -Vs- Avon T 82

Retailer said the Avon 86 T was for heavier loads and was for vans, I knew that already, but I thought it would be better to have a stronger tyre if they are the same price.....

Does anyone know of any GOOD reason why you would not put a stronger 'tyre load - rated tyre' onto a car?
e.g. Insurance, performance, design etc?

There are a few extra load car tyres about, so I can't see the problem.

It'll have an adverse affect on the ride and handling.....

It should improve the economy if anything.
The higher rated sidewall won't deform as much, so it should improve the rolling resistance.
Conversely, it won't deform as much over bumps and pot holes, so ride will suffer.

82 is 475 kg
86 is 530 kg

so not a lot in it.

The higher load won't get as hot, as it won't flex quite as much.
It'll cost more, as it'll need more steel and/or rubber in it, and better quality control.

An overloaded tyre will get hot, (deforms more when it turns) so if you should fit only the highest load tyre, that corresponds to the higher load the car can (legally) take, you'll save a few pennies than fitting a higher one.
Same as the speed rating, lower is cheaper.

So I guess there are no real problems going up, the same as changing the speed rating for a higher one.
