The great quality debate and paying extra.

The market for tyres is dependant on what you want out of them, but it would be nice to get more information on the grading of bike tyres like you do with cars. I've been aware of the car tyre guide for a few years, but I tend to buy my tyres from online retailers who provide this information on the product listing. Black Circles is a big favourite, but they can be a little expensive - so I mostly use them for reference more than anything else.

As far as your car goes, the tyres you have are setup grip and aren't expensive which means you suffer on the economy and noise factor. More expensive tyres are likely to try to get better all round results or specialise in 1 or 2 of the criteria.

With my car, I have Toyo Proxies T1-R tyres - these are "premium" tyres but I got the set dirt cheap because they are "passed their sell by date". Thankfully the rubber is intact and hasn't deteriorated so I'm in no hurry to replace them. The grip in the dry is great, but they are pretty bad in the wet and likely to spin on exuberant acceleration I'm not sure about their economy as I haven't had anything to compare to - the car had 3 different tyre brands on when I bought it and even the two that were the same were both on the left and of different models... go figure...

As for noise... well... the exhaust note drowns any potential tyre noise out really...
