some tyres last longer than others, some are quieter than others, some grip better on dry roads, some on wet roads, some on ice. Manufacturers have to trade off these various qualities against each other and against price.
Cheap chinese tyres are notoriously bad.
It also depends how long you expect to keep your car, as some good tyres last a lot longer but are more expensive. This can mean they cost less over a few years even though the purchase price was higher.
British roadstone is said to be harder and shiner than that used in most European countries so are tyres are made a nbit softer for better grip.
paying the highest price does not guarantee the best tyre.
if you tell us your car and the correct tyre size for the wheels on it, we might suggest more. There are very few independent test available, most articles are written by or for the tyre trade, most magazines can't afford to test hundred of tyres on hundreds or cars for hundreds of thousands of miles.
"Which" magazine carries out tests in conjunction with other European consumer magazines so if you have a fairly common size, there might be a report on tyres to suit you.
