I had Futura's Z rated at front and Kumo's V rated in the back. John got his new wheels, so he got new Yokohomas on his new wheels. He was trashing his Yokohomas which still had good amount of treads left on it. On my SVX, The profile of Futura tires was little bigger, so I thought instead of those Futuras, I can put John's Yokohomas. So I got John's tires and put them in front and I had V rated in the back. After I got out of the shop, I heard some noise in front right tire. I talked to John and he said that it might be tire or overtorque of Lug Nuts. So I went to a shop yesterday and rotated the tires and torqued my tires to 80foot pounds. Now I have V rated at front and Yokohomas in the rear, but noise is still there in right front tire. What can be the problem?????????/
