Leftie Biker, so it's safe to inflate the tires up to 40-42?
As long as you don't exceed the "Max Pressure" figure molded into the tire's sidewall, you're good. The 40-42 quoted by LeftieBiker is well within that (I know the "Ecopia Plus" max pressure is 51 psi, don't remember the figure for the Nissan OEM Ecopias). Some folks here have said they run it even higher than that figure, but I do not recommend that.
Many/most of us here believe that Nissan's recommended 36 psi is too low, and I am one of them. Sticking with Nissan's recommended pressure seems to cause the tread edges to wear out faster than the middle, a classic sign of underinflation. I have a 2015 VW eGolf that weighs about the same, and uses the same 2015/55/16 tire size that your Leaf uses, and VW recommends the "Ecopia Plus" tires that came with the car to be inflated to 41 psi. The tires wore evenly for the nearly 21k miles I've had this car, so VW's recommendation seems to be correct.
The downside of greater-than-recommended tire inflation is a harsher ride, and if you do overinflate too much, you will get accelerated wear down the middle of the tread.
Note these figures are for the Bridgestone Ecopia (the OEM fitment) or the Ecopia "Plus" which is what seems to be available as a retail replacement today. If your car was fitted with something else, you will need to play with the pressures until you get an acceptable balance of ride and even wear.
