Are the Maxxis and Goodyear Marathon's the only best brands out there? I really am hoping for a third option,

1. I read that KZ does not recommend Maxxis for their trailers

2. After all the Goodyear horror stories I've read, I simply don't trust them any longer.

I found that when I searched the threads here. I don't recall who posted that exactly, but he said he spoke to KZ and that's what their engineers said about the Maxxis brand. He did say they recommended the goodyear brand.

John can you explain to me what the 175 versus 185 difference is. I'm not that well versed on tires other than rim sizes.

Steve and Matthew……trailer tires made to handle a higher load…..the greater margin of safety that I referred to in my first post……my logic:

ST175/80R13…..C-rated @50 PSI Cold = 1360 Lbs. load capacity per tire…..2(1360) = 2720 Lbs.

ST185/80R13…..C-rated @50 PSI Cold = 1480 Lbs. load capacity per tire…..2(1480) = 2960 Lbs.

The GVWR of my Sport Classic 14RK is 2700 Lbs.  Thus, margin of safety is increased 260 Lbs. over the GVWR and 240 Lbs. over the standard size ST175/80R13 tire, with the use of the ST185/80R13.  NOTE: The brand I replaced the original China-made tire with was Maxxis.

I did see 175/80 r13's with a lower load rating on them. It was the Maxxis link that had them.

Steve, what is your source for "KZ does not recommend Maxxis"?  What tire brand (s) do they recommend?  Perhaps, that source is me.  See my added post further down this thread.

I replaced the 14RK China-made tires that came came with our TT, resizing from ST175/R13 to ST185/R13 and have not had any issues whatsoever.  I appreciate the additional margin of safety.

Goodyear Marathons, now made in USA, need some proving before I'll trust them again.

Steve:  Reference "Tires" in "Repairs & Maintenance" forum, initiated by Jenny and George (jjmummert).  When referring to our 14RK, with its 13″ tires, I said "I had wanted to replace with Maxxis ST-205/75R14, but KZ-RV Design Engineering did not recommend, as not enough clearance in the wheel wells."  So, Steve, perhaps my statement was taken out of context or remembered only in part.

Steve, Kenda perhaps has an ST rated tire.  Seems that they have faired about as good as the China-made tires, though.
