You're kidding...Right?

Just had new TOYO tires installed on our recently purchased Tiffin 36LA gas m/h. (2014)

They seem to ride a bit harder than the ones replaced. I see the installer set all tire pressures at 110 psi.

Now, I read that I should weigh all four corners to adjust each tire to the proper pressure. But, before I do so, fill the gas, propane, water, black and grey tanks, plus put in all our gear, tools, dogs, cats, and any people that might ride with us, before weighing.

Then add 5% for road temps, cold or hot.

I did weigh the rig for the front and rear axels, but surely there's some kind of average to stay within the safety factors.

So, flame me, scorch me, inform me....Please.

First time motorhome owner, just looking for answers.

Thanks in advance,

  • You do not have to take each wheel position weights. While that's nice to know it's not easy for many of us to get. Yes of course you can take averages from each axel and then refer to your inflation chart to get proper inflation.
