[Fot] Tire Pressures Question

[David Gott]

Walt,
On the TDR’s on our TR4’s Dad and I have found it best to end up around 30 psi hot.  They get really greasy above that.   We start with a mix of 24-25 psi cold.   I started at 23 last time at Thompson.   I say a mix of pressures as we typically run opposite pressures higher/lower by 1 psi based on the different diffs at the rear of the cars; welded vs quaife.  
Hope that helps!

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?

 

Thanks as usual,
