Optimal pressure for Conti GP 4000??

Padre 1

Just bought a new Focus Culebro, which came with Ultra Sport tyres, and am upgrading to Conti GP 4000. Wondered if anyone had thoughts on the best pressure to use; I imagine somewhere round 100 psi?? Thanks

Most tyres have the optimum pressure clearly labelled on their sidewall.

Most of the top road tyres, such as the GP4000's, operate at a recommended pressure between 110 to 145 psi (or 8-10 bar) although it can vary. The exact pressure you use then depends on whether you want speed and less rolling resistance (higher pressure) or a more comfortable ride (lower pressure).

It depends on your weight (or so i've read...)

I'm pretty heavy, and have them 100psi front and 120psi rear. They were a massive improvement in everyway over my previous tyres including comfort.

thanks for input - much appreciated!!

100psi is about right for our roads. In winter probably about 90psi.
Forget really high pressures, no benefit with rolling resistance so no need and more bumpy.

I'm about 11 stone 10lbs, and I have them at 100psi on the front and 110 on the back. Tha's about spot on for me.
