Choosing cheap tyres

Last year, I bought a set of expensive tyres at one of the best service centres in the city. I had them replaced for free and I was extremely happy both with the product and the services at first, but then it all started to change. First of all, I should have definitely chosen one of those cheap tyres sets that are easily available online. Some of them are really good; this is at least what my friends say. The tyres that I bought had been manufactured by an unknown company. Of course, there were promoted by the service centre, so I believed that they were really worth their price, but when I later found some comments on the internet, and when I finally started having some problems with them mysrlf, I changed my opinion completely. The tread looks worn-out just after a couple of months and I have also had several problems braking on slippery roads, especially in rainy weather. I think such a product should not be sold. I am actually going to complain about it to the manufacturer. This year I will certainly order one of those cheap tyres offered online. One of my friends has already emailed me some links. Why spend cash on something unknown, if you can easily get popular brand name products at a rally bargain price?
