Thanks for keeping me straight on that!

The sticker is not brand specific. The pressure/load tables for tires are standardized. e.g. every ST205/75R14 load range D tire will carry 2040 lbs at 65 psi. 


mikes is correct that the sticker on the trailer is not brand specific, but it does refer to the size and load rating of the OEM tires that came from the factory. In my case the sticker is referring to load range C, ST 205/75R14 tires. The side walls on my Kenda Karrier Load Stars are in fact, marked ‘Load Range C’, single axle rated 1760 lbs @ max cold inflation of 50psi. The GVWR for my Retro is 3500 lbs, the GAWR (axle) is 3500 lbs, so the tires are good up to the GVWR as long as I keep them inflated to 50psi cold. My Riverside owner’s manual (Chapter 11, pg. 61)clearly states, “Keep your tires inflated to this maximum cold pressure.”, so the the trailer, the axle and the tires @50 psi are all good to 3500 lbs. 

So here is some good news for white sidewall fans: My tire shopping turned up Kenda Karrier tires sized ST 205/75R14 in Load Rating D with white sidewalls. The D rating gives you a max of 2040 lbs at 65 psi (with white sidewalls).

We have almost 13,000 miles on our Kenda Karrier tires (Load Range C), with minimal tread wear and no problems, so I plan to replace them this season with the same tire in Load Range D.

Watch out. Kenda doesn't make a whitewall trailer tire, AFAICT. In fact, they state: "WHAT IS NOT COVERED BY THE WARRANTY... any alteration to the tire such as, without limitation, grooving bead or sidewall decorative material or the addition of a white inlay (whitewall) to any tire."

Without digging deeper, I suspect the whitewalls are made by others by simply grinding off some sidewall rubber and applying some white rubber in its place. You can't trust the rating on a tire modified by anyone other than the OEM.

There has been quite the flow of info on this subject. Confusing also. Iam sure moat will agree.
Since I live in Ohio and Akron isn't so far away... I am willing to stop by Goodyears HQ and discuss the information we all want to know from a professional resource.
If nothing else, at least the applied info for Endurance tires related to trailering. Especially inflation information.
Then i will reveal the results.

mikes: Thanks for the caution! retro195 man is correct about this subject being confusing. I apologize to the forum for being a contributor to the confusion, but I think we all want to have some definitive answers on what is safe and what isn’t.

A couple of things seem clear: The Coker tires were not trailer tires and a number of Retro owners had problems. Riverside switched from Coker to Kenda and the reports of blowouts subsided.  The Goodyears and Maxxis are a good choice for an upgrade. Weight ratings for a given load range are specified at the max cold inflation pressure listed on the tire sidewall and it is safe to run that pressure. The government mandated sticker numbers on your trailer refer to the size and load rating of the OEM tires. If you install tires of a different size or load rating the sticker numbers are no longer accurate for the different tire.

Now the white sidewall issue:

mikes is right, the Kenda website doesn’t show white sidewall tires and the load ratings they list for C and D rated Load Star tires are slightly higher than the ones advertised for the white sidewall versions.  I think mikes suspicion may be correct that a third party (not Kenda) is adding the white sidewalls. Since the Kenda warranty has a specific exclusion for added sidewall mods, it looks like they didn’t want to be on the hook for liability for the modification that was oitside their control. The warranty exclusion does not necessarily mean Kenda disapproves of the mod, but rather that they cannot assume liability for something done to their tires AFTER they leave the Kenda factory.

Kenda has an office in Reynoldsburg, Ohio and I plan to call them later today for clarification

Having said that, I have had a good experience with the Kenda white sidewall tires on my Retro and I am not aware of any reports from other Retro owners of problems. If you are still reading..... thanks for hanging in there! And thanks to mikes, retro195man and other posters for their input.
