I changed all 4 of mine in the summer, for infinity eco max at a total cost of £316 including balancing and fitting, I drove to London and back on Saturday,480miles and its hard to tell the difference
These are fitted to my A4 black edition, I'm no racing driver, and this runout isn't something I do regularly, they've covered 4000 miles now and they grip well, there quiet, the handlings no different
Do I wish if spent three times that amount to put Conti's on Definately not, I believe you get what you pay for but I do wonder if Conti's are worth the premium against these so called Budget tyres
