The Toyo's in the 195/50 size (ST "magic tire") want very low pressures. I run as low as 24 in back. Because I run such low rear pressures, I kinda tend to stay a little low on the front Hankooks too. So I run between 36 and 38. Other people run up into the low 40's.the 225 kooks wouldnt be too bad I think I might give them a try what kind of pressures are you having to run bill?
