Hi all, i have alloy wheels that i think were from a renault clio and when i bought them i had new tyres put on them. The tyre fitter inflated them and i assumed they were going to be roughly the right pressure. Although on checking the pressure i find that all four are 25 psi. Is this too low? The tyre pressure on the drivers side says f33 r29 should i increase the pressure to those figures? Any help greatly appreciated.
