I would have thought just the opposite.

When I bought my Yamaha from Carts and Clubs, they told me 18-20 psi. Oh well, I guess it depends on the day of the week.

Maximum pressure will yield the best MPG. I always run the sidewall rating plus 5 psi inflated with Nitrogen. Pressure will not increase or decrease with temperature change.

The pressure listed on the sidewall is typically a maximum pressure. It is easy to check; it will say something like "max 35 psi". I don't believe exceeding this figure is a good idea.

Pressure will increase or decrease with temperature regardless of whether you are inflated with 100% nitrogen. Nitrogen will follow the ideal gas law. By the way, "air" is 78% nitrogen and 21% oxygen, the remaining 1% is small amounts of various other gases.

It depends on what tires you have. If you have 8" tires then that is probably a good pressure. If you have 10" tires, the "recommended" pressure may be higher. Check the sidewall for the maximum pressure. You want to be below that. Many 8" tires have a maximum pressure of 22 psi. My 10" Loadstars have a maximum pressure of 35 psi and I run them at 25 psi. I would follow the recommendation of your golf cart dealer/mechanic.

Not typically for the tires you see in The Villages. You may be able to find an exception.

Mine are 10". They told me 18-20 psi. My understanding is recommended pressure has a lot to do with the loading/vehicle weight. Too little or too much pressure increases tire wear.

That is probably fine. My Loadstars are rated for a load of 910 pounds at 35 psi. Since the cart only weighs about 600 pounds empty (and there are 4 tires) I am not anywhere near the load limit of the tires so a pressure well below the maximum is fine. My dealer recommended 25 psi. I would stick with whatever your dealer recommended.

22psi for 8" tires, 25psi for 10" tires should be just about right under normal conditions.

Anyone remember when the starters :police: use to check the tires and tire pressure before you were allowed on the course?

In the good old days you could ride around in a cart at 18 PSI. Now it's 28 PSI. Talk about inflation!
