Tire Pressure? We don’t need no stinking tire pressure
Posted on September 18, 2010 by Tom Colby
Just a quick note here. Long time ago I, like many of us have always stuck to the general tire manufacturer’s inflation recommendation. Typically for a 13 inch tire they’ll say anywhere’s from 28 to 32 psi, correct? That’s based on a car weighing in at around 2,000 pounds. Believe it or not, if you’re running a modern tire of just about any size on a Spridget, you actually want to be running about 18-20 psi cold on the side-curtain cars, and 20-22 psi on the roll-up window cars since they weigh a bit more. Aside from riding more smoothly at the lower pressure, you most likely find it to be less “darty” over bumps and will stick to the road so much better. Give it a try, if you don’t agree with the results, the worst-case scenario is that you’ll have that painstaking task of putting air back into the tires! Also, if you’re really adventurous, try setting your toe-in at zero instead of the BMC called for 1/16″ toe-in. I’d love to hear from any and all of you about your findings if you try it. I might even post views telling me I’m full of horse-hockey, too!
