New question, I had a flat on a front last month on the road and had to replace tire. So I bought two new ones for the front. Now replacing the 4 old ones (6 years) with new Hancock’s AH 37s which replaced the hankook AH12 which is no longer available. The new ones up front are Yokohama’s. Wanted hankook which had proved to be an excellent RV tire but wasn’t available. Any problem with this?
