    Subaru Impreza 2011: What is the optimal tyre pressure?

    Subaru Subaru Advice Subaru Impreza Subaru Impreza Advice Subaru Impreza 2011

    When I recently had four new Yokohama 205/55ZR16 91W A Drive R1 tyres fitted to my Subaru Impreza the tyre man filled the tyres with "nitrogen" and inflated them to 35 psi. The recommended pressure is 32, but he said the increased pressure puts more tyre on the road for better wear and will not need to be pressure checked for 66 months. Is this okay?

    The tyre man has fed you a line of BS. The is some advantage in running nitrogen in a race car that is operating under extreme duress on the race track where it would be a more stable gas and maintain the pressure better, but there's no advantage of running nitrogen in a road car. I bet he charged you for the gas as well. It might not drop as fast, but the pressure will drop just like it would if you used air, so you still need to check the inflation pressure regularly.
