dmullen,

The problem you're going to encounter is tire size availability. Your RV comes standard with 205/75R/14 LR C (6 ply rated) tires. They are designed to carry 1760 lbs at 50 PSI.

The only "other size" that Maxxis makes in the 14" tire is 215/75R/14. It also is only available in LR C and carries 1870 lbs at 50 PSI.

There are no other 14 inch tires available from Maxxis, and both of the ones that they do make are Load Range C rated. So, trying to find an alternative tire in a LR D or LR E, even if your wheels are rated greater than 50 PSI is going to be difficult. I don't think you're going to find tires in your size, 205/75R/14 rated any stronger than LR C. If you consider going to a 15" wheel size, there are a number of options for tires in LR D and LR E configurations, but they are all significantly larger than your current tire, so you may (probably will) have issues trying to fit them into the wheelwells on your trailer.

As for having the wheel/tires balanced, it's the general belief that balancing the tires will help prevent wheel-hop which is the major cause of sidewall flexing which causes temperature buildup and possible sidewall damage. So, yes, balance your wheels when the new tires are installed.
