Hey guys. Can someone explain the above mention of tire psi being 40 front and 45 rear? I have all mine set at 36 as that's the recommended according to the chart on my door. 83 sunrader 6lug rear 5 lug front. These are what I have. 6ish months old https://m.tirerack.com/tires/TireDetailsServlet?tireMake=Yokohama&tireModel=Y356&partnum=8R43568

The numbers on the door was for the pickup before the home was added  to the back.  I run 45# on the front and 50# in the back . I have the yokohama 365 on mine too.  Was Highly Recommended by the late Sunrader  Bob. He was the Toyota motorhome guru !

I don't know about all Toyota motorhomes, but Winnebago at least added their own stickers with tire pressures indicated. I don't know if other manufacturers just left the Toyota stickers.

'Correct' inflation pressures have been discussed before (often) as well as Load Inflation tables.

Ok I will bump mine up. I wonder why different pressures in the front and rear? Interesting.

Tires are designed to the most efficient profile for stopping, traction, braking, resisting hydroplaning, control etc.  This profile is altered by the addition or subtraction of weight, which can be compensated for by changing air pressure in the tire.   Best I can describe it,  HTH   Jim

TIRES!! Learn to read a DOT date code. The coach I just bought had great looking tires, lots of thread and only 1 tire had some very minor weather checking. 4 of the the tires are 14 years old! I had one blowout on the way home.

There is some controversy weather a tire is good for 6 or 10 years, me personally 7 years max. I also had a flipper in Tampa tell me a coach had new tires, they were 6 years old with tire shine on them.

Learn about tire size and load range also to make sure they are the right tires! HTH JIm SW FL

A friend gave me my camper and the tires looked good, one of the valve stems on the rear dually went bad so I took it to discount tire and they wouldn't touch them because they were seventeen years old. They won't touch anything over ten years old. I put all new rubber on the rig. The front tires were only 5 years old but were the wrong load range so we did those to. I'm not going to mess around with something that could kill you if it goes bad.
