I'm running 225/75/15 D rated tires on aluminum rims inflated to 65 psi. The only GY Endurance tires I find this size are E rated inflated to 80 psi. I do not know anything about these rims other than they are round aluminum objects.
Should I be concerned with airing up to 80 psi on these rims?
If I do go this route I will get metal valve stems.
Thanks

Not trying to hijack the thread but related. I just replaced my LRE with LRG tires. The Max pressure on the E's are 80 and the G's 110. The Rims do support the pressure. The Labe from the manufacturer state 80PSI based on the E tires. Do I inflate to 110PSI with the new tires or a little lower?
My concern is at 110PSI the tires will be very stiff and it would cause more bounce in the trailer while towing, is that valid? I know at a lower pressure capacity is reduced and more heat buildup may occur. Anyone out there who has upgraded to G's, what do you do and what if anything have you noticed?

According to the GY chart I would only need 40 psi in my tires since my 5er only has 7200+/- lbs on the tires. Divide by 4 thats 1825 lbs on each. 40 psi gives my 225/75/15 tires 1880 lbs.
Assuming my left side tires are carrying 700 lbs more than the right side. Using those tables and adding 5 PSI would still allow me to run the 235/80R16E's on my 5er at 60 PSI. Not likely. I have never had a wear problem running 80 PSI and always end up changing tires because of age, not wear.

The left side tires on my 5er are carrying a good 800 lbs more than the right side, so I am not about to just divide my trailer weight by four and set pressures for the max tire load rating at that weight with no surplus load capacity.
Per GY Tech they say to weigh each tire if possible and use the heaviest weight on the axle and add 5psi to what the weight/inflation chart says. This if their recommendation if using the charts for upping the load range from lets say "C" to "D".
Thats for motorhomes and trucks ,most tire load tables I have seen also have this statement at the end /back in fine print "however in applications where axles are closely spaced i.e. trailers with mulitable axles use maximum sidewall pressure .
If its a trailer don't waste your time looking at the table' look for the fine print.
As I said per GY Tech when upping load range do as I said above. I guess the Load/Inflation charts are for nothing as the tires say "For Trailer Use Only".

Overinflating can reduce traction, braking ability and handling, as well as result in uneven wear and an uncomfortable ride...The proper air inflation for your tires depends on how much your fully loaded RV or trailer weighs...See load inflation charts...actual air pressure required should be determined based on the actual load on each individual tire.- Goodyear Tire Care Guide (emphasis added)
Inflation pressure should be adjusted to handle the tire carrying the heaviest load, and all tires on the axle should be adjusted to this pressure.
