New Maxxis yesterday- not so sure
I need some advice. I bought brand new Maxxis 8008 yesterday at a shop I have never used before. I had to travel 160km as they were the closest shop that has Maxxis brand tires. They are 225/75/15 ...

From Roger Marble's RV Tire Safety blog, "As a tire engineer I suggest that people select an inflation pressure that will provide at least 15 percent extra load capacity over the heaviest loaded tire on an axle" and "If you have a multi-Axle trailer you should be running the pressure on the tire sidewall.". There is a LOT of great info. on his blog.
Yes, as mentioned, always run the tires at the sidewall max. psi. Would be a good idea to take a run through a scale and determine the TT's GVW (while there can also get TW and TV's actual payload capacity). An estimated GVW of 8,000 is realistic and would be a payload of about 1500 lbs which would be around "normal" but depends on any kids, pets and in-laws and stuff needed for them that would be in the trailer. The payload in our 29' TT is well under 1K lbs for two adults and a dog. You can sometimes reduce psi based on actual load on tires but higher reserve load capacity is a good thing plus the TT doesn't need a softer ride.
So if your TT does indeed weigh around 8K lbs and you subtract the TW of say 12 percent, the actual weight on the tires would be 6800 lbs on a total max. tire rating of 10,160 lbs (at max. psi) for a reserve load capacity of over 30 percent which is very good. Unless you load your TT to the GVWR max. and were heavy on one side you should be fine as long as the tires are kept at 65 psi (cold @ ambient temp.). Our TT comes standard with LRC tires and we upgraded to LRD, have over 30 percent reserve capacity and have never had issues.
Run 65 psi and you are *very* good to go. Happy camping. :)
