I'm not sure about D Load Range being OEM for 2015. My T21QBHW came with ST205/75-14 C Load Range tires and it is the biggest, heaviest A-Frame FR currently makes at 2,352 pounds Unloaded Vehicle Weight and a GVWR of 3,336 pounds.
That hefty weight doesn't leave a lot of room for error on most C Load Range tires if you are at, or even near, the trailers maximum GVWR. For that reason, along with a general concern over the stock tires, I'm looking at replacing the OEM tires.
I've decided to go with Maxxis 8008 ST215/75-14 C Load Range
tires. While staying with the OEM 14 inch rim by "upgrading" to the 215 width, versus the OEM tire's 205 width, provides a slight increase in tire load capacity. The 215's have a maximum load of 1,870 pounds per tire, 3,740 pounds per set, versus the Maxxis ST205/75-14 Load Range C tires at 1,760 pounds per tire or 3,520 pounds per set. Both tires have the same maximum Air Pressure, 50 PSI, and are close enough in size that I
do not expect to have any wheel or fitment concerns.
While that change is only 110 pounds per tire, 220 pounds per set, the higher rating adds a little bit more comfort
margin for me
at roughly the same price. When looking at only
the trailers GVWR (3,336 pounds) the 215's are rated at approximately 9% higher than the GVWR, at the maximum allowed weight per set, versus approximately 5% higher than the GVWR for the 205's. There is my
I do not
advocate going over the factory GVWR, running "overweight
", nor do I intend to ever do so. And I know
that upgrading tires alone will not
increase my GVWR rating by even one
pound. But I believe upgrading to the Maxxis 215's will result in a less stressed, cooler running tire which is one of the key factors in tire life. I'll also be installing a Dill TPMS
at the same time I swap tires.
I advise anyone looking at replacing their tires to do their own research and carefully check out their options. What I
, or anyone else, thinks will works best is not necessarily the best option for everyone. I do not
claim to be a ST tire expert, nor have I found one I
, so I've spent quite a bit of time researching before I made my
choice. This "upgrade" is about $600 for three tires, I'm replacing the spare tire as well, and the Dill TPMS. I'll find out if it was a good choice and will only have myself
to blame if it wasn't...
I'll get off my soap box now....
and I apologize in advance if this came across as a "rant" as it wasn't meant to be one....
