Tire pressure update

[Mudchief]

I posted before about the pressure rising when pulling the Montana. I contacted Doran who also makes Pressure Pro and they said that in weather up to the low 90's that a 10 to 12% increase is normal and above that 15 to 20% is normal.They told me that they set the Doran 360 to alarm at 25% increase because that is what the tire companies rate the tires for. However I am sure that was American companies and does the tires from China meet that. My tires from China were running 95 pound at 94 degrees which is about 18% high. like I posted before that may be why those Mission tires from China are blowing.

for what it worth. I just went a little over 1300 miles to Florida. most of that time my truck tires were. FT 86 psi & 87 temp, RT 91 psi & 98 temp, trailer tires were 92 psi & 100 / 102 temp

all tires started at 80 psi
