Tyres make a car. As shoes make a man? Or was that manners that make a man?
With all that pimping of your ride, those mods, transmissions, and extractors in the world won’t be worth the seat of your pants if the tire pressure isn’t maintained properly.
Having owned an Opel, Lancia, and BMW before [excluding Japanese makes], the VW Jetta makes for a nice, comfy, zippy ride, and that’s mostly due to the right tyre pressure and some tweaks. I promise that if you take some time to READ your tyres, it will reward you with comfort.
My Jetta door sticker says I should run 30 front and 41 rear, which seemed strange. And the Michelin Energy tires have a max pressure of 51 pounds on the sidewall. I thought that was odd as well.The car manufacturers are VERY nervous about tire pressure, esp. after what happened to those Ford Exploders. They recommend tire pressures based upon the worst case scenario ie. fivepeople crammed into the car with luggage.
You’ve heard this before: Choose the pressure that fits the conditions. Consider weather and load. Are you are driving alone with no passengers? Is the road icy or muddy? Nice metalled road?
Tyre manufacturer recommendations : 1.9 Bar Single driver. 2.2 Bar with full load.
My recommendations : Cold –
