Just something to note. The proper tire pressure is listed on the door sticker. 80 psi is probably pretty close to what the vehicle tire spec is though. Not here to criticize. Love watching the tv show and you tube channel. Thanks.
Yeah shouldn't be going with the tire pressure on the actual tire. Now a trailer you want to go with what the tire says but a vehicle should be listed on the door as Paycheck Monster stated. The front and back tire pressures can be different, for example my truck front 30psi back 33psi.
Now if we could get the dnr to implement these size regulations on the winnebago system we would be Golden. Although after 10+ years of fighting for a change and it hasn't done any good
