Savero Tyres

Anybody know much about them? They were on my Surf when I bought it nearly 12 months ago, and although I havent had any problems or had any complaints about them I suspect that they were purchased as a cheap job lot by the dealer. They are Indonesian and made by Gauteng. Although still relatively new, I am already looking down the track towards their eventual replacements, and need to purchase a replacement spare soon as this wasnt included in the compliancing it would seem. It seems that tyres are a very emotive subject, that leaves new comers like me baffled. The current Savero's are 31x10.5 R15 A/T, and although I do mostly city driving, I do go out with a club that tackles all sorts of conditions as often as I can. I suppose I am after a good road tyre that can handle a wide variety of conditions and wont cost me the earth and that lasts forever. Is that really too much to ask? I have my flak jacket and helmet on ready.
