225/40/18 run in both winter and summer. I took it as a golden mean between summer and winter. I can't be happy. Works well, at least in our climate (Hong Kong). instead of 2 sets. The only thing I can say that is not in her favor is rather weak sidewalls, an evil pit with sharp edges will easily break through the barrel if you fly in at medium speed. For neat old man driving. Different pros: Solid "good" in all positions. For a quiet measured ride, although sometimes he gave oats in turns, not a single breakdown. With its cons: Within the limits of statistical error. If necessary, you can drop to the pillar.
