It looked like all tires were right around 30. The tires said 40 MAX, so I filled them all to 35-36. The light did *not* go off. I had to get somewhere, so didn't put more air in, but will try that later today. Strange though that the light's still on?


If you have the stock tires, they should read '44' max, not 40. Also, it takes a few miles for your tire pressure light to go out. The minimum pressure according to the car manufacturer is 36. You may get better wear though if you take it to 41.

Hmm, don't know why, but the tires I got with my Leaf do say 40 Max, not 44. But yes, the light did go out the next day. And ok, I think I'll up the pressure a bit more. Thanks!

Which model of tire do you have? The Ecopia EP422 tires are labeled with a maximum sidewall pressure of 44 PSI, unless Bridgestone decided to change something mid-model.

All four tires lost the same amount? Not likely. More likely they were improperly inflated at the dealer. Proabably done by some flunky who either didn't bother to find out what the correct pressure was, or who believed a bad gauge...like the ones integrated into the nozzle.


I too had the warning light come on. What seems strange though is that the little warning triangle also came on. So two warnings for one problem?

But when I checked, every tire was exactly at 30 psi. This was done with a mechanical guage, which in my opinion is at least as accurate as a digital one, maybe better than a cheap digital one. In fact, since I too had the car for just about six weeks, I thought the warning might have been just some preset mileage interval for a reminder to check tire air pressure.

With the Prius, they inflate the front tires 2psi more than the rear ones. So I put 40 psi in the back and 42 psi in the front. I don't know if the Leaf should have all four equal though. If so, I'll put 2psi more in the back ones.

The Prius has a higher percentage of weight on the front wheels. The Leaf is better balanced and thus uses equal pressures all around. 40 PSI cold is a good working number to use. Don't exceed the tire sidewall maximum pressure of 44 regardless.

The Nissan recommended cold tire pressures should be on the sticker on the driver's side area. IIRC, the consensus is that the recommendations are too low.

40psi is a good, conservative (well under max on sidewall) pressure that will improve range, handling and sidewall strength. 38 is as low as I'd go.
