General Request to ALL
When asking about specific loads or inflation or alternate size it would really help if the basic information was provided.
While I am more than willing to consult the standards books or provide an opinion I really can't spend hours trying to first solve the problem of knowing what tire I am being asked about.
Please provide the "Complete" size. That would include the Service Description part that comes after the rim diameter as well as the type tire which is the letters up front if any.
235-r-15 isn't correct but many times that is what we get.
If you have an LT235/75R15 107/110Q Load Range D is actually a different tire than a
LT235/75R15 Load Range D.
Also concerning the load on the tires. As a minimum you should have a real scale measurement of the total load on all the tires. While you may feel you know a lot about your "Death Valley Special" RV not all of us know if it has one, two or three axles.
Ideally you should have at least once had your RV weighed with certified scales where you can get the individual loads on each tire.
Almost ALL trailers are out of balance axle to axle in addition to side to side with a good portion (usually the ones with tire problems) discovering that they are at least 5% off and sometimes as much as 15% out of balance.
So in addition to the complete tire size how about:
"I guess the 4 tires on my trailer carry 10,000 pounds"
or
"The tires on my front axle carry 5500 and the rear axle 4500"
or best of all
"RF 3300 LF 2200 LR 2700 RR 1800"
Finally if you really want to do a bang-up job then the tire Brand and design as molded on the tire, the Max load and inflation as molded on the tire and an in focus picture of the placard would be of great help.
I know that if given the choice of who to answer first I would answer the person that supplies the most information first.
OK I am now stepping off my soap box.
