Only you can answer the question "Is it worth the risk?".
I decided many years ago that the answer is an emphatic no! The only budget tyres I've used have been vastly inferior in terms of grip. It is entirely possible that ones with good grip exist, but it is likely that longevity will then be compromised.
Stick with Michelin or Continental is always my advice. Bear in mind that significant saving can be made by ringing around. Don't be afraid to mention other supplier's prices; even some fast fit places will haggle.
If you search this group's archives using Google Groups, you will see that this question is asked regularly. The answer from the regulars, often with many years experience both as private motorists and in the trade, will be broadly the same.
