From memory when we ran our previous tyres at 80 psi on the rears we got well into the 90's when we were travelling at 60/65mph during the summer in the UK.The tyres front and back say 79.5psi. TyrePal says to set the Hi value to +25%. This is almost 100 (the unit goes up to 99). The low value is -15% so 68psi.
The hi value seems too high to me.
Is this correct?
thank you
