[Fot] Tire Pressures Question

[Steve Adams]

The first line should read   In the cold and wet UK.  I run these pressures all weathers as there is never that much variance in the UK.

>>> I’m racing my TR6 at COTA in a few days and have a question about tire pressures. Normally on a big track I run Hoosier SM7S 205 50 15s on my 15X7 wheels however SVRA requires I run treaded tires so I purchased some Hoosier TD R 23.0X75-15s. With my SM 7s I typically start my tires cold at 30 psi front and 25 in the rear and when hot I don’t want the pressures to exceed 34 front and 28 rear. With this in mind do any FOT members have recommendations on tire pressures both cold and hot for my TD Rs?
