Take a typical example of a car tyre size marking, 205/ 40x17 82R. The load rating is the 82 part at the end, and R means radial. The higher the figure, the higher the load rating, and yes it does matter that your vehicle has the correctly load-rated tyres or you risk a blow-out. I often see alloy wheel and tyre packages for sale that have a very low load rating tyre being used, and that would preclude them from being used on anything but the lightest cars on the road. The load rating is something that very few people know about, or take any notice of, but if you had an accident, and a sharp-eyed insurance loss-adjuster noted your load ratings were insufficient, then you could be without insurance cover. As a very, very rough guide, an 82 would be OK for something like a KA or a Fiesta, and something like a Mondeo would need an 88 or a 92 rated tyre. |
