I'd probably run the 25c tires 10 psi higher.





I will never run a big difference in pressure front to rear. Racing days, the word was 5 psi or less. We never questioned it nor regretted it. Now I hear the "experts" say we should adjust our pressures by the percentage of weight front and rear. No way am I ever doing that! If I hit a stone in a hard stop behind a car, I DO NOT want to ever pinch flat and blow a front tire. But in that hard stop, I have 100% of my weight on that tire. Carefully adjusting the pressure to be best at 40%? Not me! I'll stick to what those vets told me 40+ years ago. Knowledge that was probably 80 years old then.
