Hello, My Toyo Proxes T1-S 215/40/17 on my Mini Cooper have almost run out of tread on both front and back. I've gone through 4x fronts and 2x backs in just over 15,000 miles. I can still get hold of the T1-S and I love the grip, but I fancy trying something a bit different and more hard wearing. Not too bothered about cost, but the cheaper the better. Hard wearing is a must. What do you recommend? Thanks!
