A8 I'm not knocking you at all mate, I think you are very typical of tyre shoppers.
And Volkswagen. Have you seen some of the truely shyte tyres they are fitting on some of their mainstream specification cars - Kumho, Matador, Firestone . . .

However when you think about it they are the most important part of any vehicle as they are your only connection with the road.
You are so right.

Without any shadow of doubt, tyres are THE most crucial item on a car - for performance, handling, braking, safety, etc. You could have the best highest spec ceramic brakes, with massive 10-pot calipers, or the most expensive coilovers, or the most highly developed ESP system, or the most powerful engine - but these are all nigh-on useless if the tyres don't provide the necessary grip!

How do you judge what is a budget or performance tyre though? There are the obvious big names that we all recognize but for example Maxxis are deemed a budget to mid tier tyre yet in the world of mountain biking they are one of the best.
Dunno about Maxxis (for me, the jury is still out on them for car tyres). But 'budget' tyres are generally deemed those which originate from eastern Europe (Hungary, Slovakia, etc - ever tried 'Trayal' tyres? Just make sure you have shares in Andrex), and the far east (such as Korea, China, Taiwan - but not Japan). And they can also include the 'lesser' brands which are owned by the premium brands - so Firestone (which is owned by Bridgestone), BF Goodrich (who are owned by Michelin), General (owned by Continental), Dunlop (who are owned by Goodyear!

) and so on - but this is more of a grey area.
