Recently put 4x Sailun Atrezzo ZSR on my S-Max. History as to why first: Had Goodyear Eagle F1's on the rear that were shot and Mich Primacy 4's on the front. I was going to replace the 4 F1's with a cheaper tire (about £100 each) but a blow-out forced a tire change on the front. Only ones ATS had was Mich Primacy 4's @ £158.00 each!! So had to have two on front. Don't rate the P4's at all. A job change meant commuting 60 miles a day went down to 16 miles a day. So decided to look at decent tires at less than £100 each. Decided to go for the ZSR's all round. (£66 each from National Tires). Was apprehensive at first but the ZSR's are a great tire. Ride comfort is the same as far as I can tell, but I am using different roads (but of a similar type) with new job. They grip very well, (not used in wet yet) & no difference in fuel economy . They may be just slightly nosier but not sure as using different roads as previously mentioned. They are well worth considering. Not sure what they'd be like on a performance car but my S-Max 2.0Tdci has a remap to 210Bhp and it's a big car. No confidence lost at all with the Sailun Atrezzo ZSR's. Have yet to tow the caravan with them but do not see problems cropping up there. Will be buying again, no hesitation. For normal road use on a family car with a 'spirited' driving style, I will not be paying top prices again. I was a tire snob before, but these are very, very good at less than half the price of what I used to pay. Tire technology and methods of manufacture are leagues ahead of where they were years ago. These are better than I thought, very happy with decision I made. Will buy again.
