So I replaced my OE tires with LT tires last fall but kept the stock size. Wondering what everybody likes to do for tire pressures in this case? I have been running 48psi as that is what a couple calculators have recommended but I am seeing anywhere from 48-50psi as the recommended pressure. Tire shop wants to put them at the door sticker pressure of 35psi, but that was for a 116T load tire not an E range.
Door sticker: 275/65r18 116T 35psi (all four)
New tires: LT275/65r18 123S
I have attached three different online calculators but to me it makes sense that the pressure required *could* change since the two tires are designed with different load ranges and pressure requirements. Interestingly running 48psi for the past 8 months I seem to experienced rather even wear so unless there are compelling reasons to do otherwise that is what I intend to continue doing.
