Hello,
I'm looking to buy some new tyres and I was looking at some of the internet tyre sellers' web sites. They emphasise that if you buy tyres of a lower rating than that specified by the car's manufacturer, you can invalidate your insurance.
How do you find out what the rating should be? I couldn't find anything in the handbook. I don't think copying what is already on the car is 100% foolproof because the previous owner could have changed the tyres to a different rating.
Is the load rating, the maximum weight of the car divided by four?
Why do we need so many speed ratings? For example T is 118mph, H is
130mph, V is 149mph. In the UK we don't get to drive this fast, so surely anything rated up to 100mph should be ok?How does a fast rated tyre differ from a slower one? Is it thicker or made of a different rubber?
Thanks, Stephen.
