Decades ago I was asked by: William Egan - Retired - Chief Engineer/Team Leader - Goodyear Tire ... https://www.linkedin.com/in/william-egan-49011222 to weigh each of my wheels while still on my EV. I found I could do this at a dump/refuse center. Normally, the public would drive up onto the scale plate (whole), and then weigh again after they had dropped off their junk/refuse. Instead, I went to the center on Sunday when they were closed, but the digital readouts on the scales were still on. I drove each wheel, one at a time, onto the scale, documenting each wheel's weight. The Goodyear rep (now retired) used those weights to have me adjust the tire pressure I used on my Goodyear tires. My rear tires carried more RWD vehicle weight than the front tires. I was advised to set my front tires to ~45psi, and my rear tires to ~55psi. (Someone verify the following) I am thinking the reason the i3 EV has wider tires in the rear is the i3 weight distribution front-to-rear (like my old EV) is not the same. If after weighing each of Lawrence's Leaf EV wheels, it might be, Lawrence would use the wider i3 supported tires in front at a high tire pressure, and the narrower i3 supported tire in the rear at a lower tire pressure. The last thing I can suggest, is if Lawrence is eyeing using i3 sized/supported tires, he chat with the i3 forum folk to know which brand and model tire works well for their i3 EVs.
