I currently have 716 Kumhos (grand touring) H rated on our 1999 Lexus ES 300. I was hoping to go to a 215/60/15 instead of the OEM 205/65/15. I see that that the Falken 512's are only an H rated in that size, albeit an all season performance as opposed to the H rated touring I have now. My other choice would be the V rated Kumho ASX which is only available in the 205/65/15 not the 215/60/15 I was hoping for. My question is, would the H rated Falkens have more stiffness than the current tires I have or should I just go with the ASX v rated Kumhos. I' m just looking to get rid of some of the softness in the sidewalls without modifying the vehicle itself. I still would like the tire to be quiet and have good wet traction and some light snow traction. The ES 300 did come with V rated as OEM I'm just not sure if it was a V rated touring or performance all season, and would that really make a difference in sidewall stiffness.
