Price of tires…

At LR-G I believe that some tires will be "Commercial" grade i.e. all steel construction. Others may be more like regular LT construction i.e. Polyester / Steel. Commercial tires have in general proved themselves to be more robust and able to deliver longer life.


If you have confirmed your actual weight and that LR-G is what you need you would probably be better off with the all steel construction and to run at least 10% more inflation that the Load Inflation table advises for minimum inflation as long as you do not require full LR-G inflation.
Tireman, Are you recommending using 88psi using Load Range G tires as a replacement for the Load Range E tires that had a 80psi inflation?

Thanks,

Paul
 
We bought a 371 Fuzion that came with Sailun 235x85x16 tires 10 yrs ago. Never heard of them before but they were great tires. Don't know if the quality is the same but I would buy them again if I needed that size.

3 years ago I purchased TransEagle all steel load range G. The specs are exactly like Sailun except one speed range better. They were less than Sailun. I've had zero issues with them.

Cold inflation pressure should be based on the ACTUAL load on the tires and the Information found on the Load / Infl tables for your subject tire.
The tables give the MINIMUM psi for a given laoding so I recommend a +10% on the table inflation number.


I would need to know the scale reading for the load and tire size and Load Range to offer more detail reply. You can't base inflation on what the old tire spec was if you are changing size or load range.

I struggle with this during this time of year in the south. We traveled back from NC Friday morning and all 4 tires on the RV and my 4 pickup tires were all underinflated and in alarm. By the time I got home they were all 10 psi overinflated.
 
Is your system "Factory" or aftermarket? can you set the warning levels?


The only pressure you need to be concerned with is the morning cold inflation. If you start out correct based on scale reading you should be good all day and should not be getting warnings as a gain of 20% in PSI cold to hot running is not unusual.


Without a lot more info I have no idea what your problem really is.
 
Disregard the truck. That's a separate issue that doesn't bother me that much. When we left out on Friday morning the RV tires were all at just below the 100 psi alarm and in the high 40s low 50s temp. By the time I got home they were all around the 120 psi range. Temps were still low. 60s and low 70s. That's a bit too overinflated for my liking. So to get them down to a good warm pressure I will probably have to take 5 to 10 psi out. That will be grossly underinflated. I think sometimes too much data is not always a good thing.

I still do not know haw you arrived at 100 PSI being the correct cold inflation. Your tires have a PSI and load capacity associated with that sidewall PSI that is stated on the tire sidewall. I am wondering what test data you are basing your "feeling" that 100 psi is too high for a LR-G tire. You mention temperatures but am I correct that these are the air temperature (Ambient) at the time you were checking tire pressure? Does the sidewall PSI of your LR-G tires say 100 PSi?

Tire temperatures need to be measured when the tire has not been in direct sunlight or driven on for the previous 2 to 3 hours.


Ambient temperature during the day should not be part of your concern till you have confirmed proper inflation pressure based on a known scale reading of tire loading. Whos Load / Inflation table are you using as your reference?
For a reference, Gy shows a 265?70R22.5 LR-G as being able to support 5,205 @ 110 psi cold in single position.
