Blimey I'm away for a couple of days and come back to all this! Cheers for all the info guys, it's much appreciated. I'm a great believer in not scrimping on tyres after all they are the only thing that keep your car in contact with the road! The only budget tyre I've ever come across that was decent was Nankangs, they just don't last too long unfortunately but did provide good grip in the wet and dry. I'd ideally like to replace all four tyres, but not sure I can afford to, especially as my road tax is due as well, plus one of the tyres was only put on the car about a week before I bought it, seems a shame to just sling it away.
Thanks again.
