Tireman9, how could you set loads by temp. I never heard of that, scratching my head on that one.....

Knowing that pressure changes about 2% for a 10F change shows the numerical relationship.

I wish TPMS didn't report temperature as some are claiming they use temperature to set tire load.

I have run both types and found the external lower overall cost when factoring in the need to pay for dismount & mount & balance when you need new batteries with internal

Good deal. Thank you for the response.

My assumption is that the TPMS temperatures are there to warn you of elevated temperatures due to failed axle bearings or brakes. Or for those that do, heat created by overloading or excessive speed.

I have never heard of that either, but I don't doubt there are people out there who have tried it. I have heard of people adjusting their pressures due to ambient temperature changes though (e.g. summer vs winter)...maybe there's some confusion there.

Yes, I think for cost and (battery access) convenience, external wins. For appearance, anti-theft, and potentially higher accuracy with temps, internal wins.

Read a post where one guy was trying to "balance" pressure to get identical temperature readings.

My question isn't about temp. or press. but more about when is the time to replace the tires. I have a 2013 Solera Motorhome 24S. I have had it for 4 years now and have 25000 miles on the it. I've had the tire rotated once in that time and new valve stems put on. I keep the tires covered when not in use and check the pressure on them regularly. The side walls look good and there plenty of thread still on them.

I have heard that they should be replaced after so many years, anyone give me an idea of the standard on replacement?

IMO on LT tires I wouldn't be concerned of age until 8-10 years, but I feel that has a lot to with how the tires are loaded. Max load equals more flex/pressure, heat etc.

Lt's are different than St's.......St's 4 years if a lot of miles and heat/cool cycles

Motorhomes are different than trailers. Due to unique tire loading (side forces) the life of tires on towables is shorter and many feel 3 to 4 years is a reasonable life and much longer is pushing the limit of having a potential failure.
For motorhomes 6 to 8 seems reasonable with 10 being an absolute max.

There are however no guarantees.
