Another tire question

That Kumho 857, Maxxis, or Goodyear Marathon should serve you well.
Yes replace them all.

Ok I had my first blowout this camping trip. I am running 205/75/r14 Goodyear marathon. They are 4 years old now. I normally run them at 45psi. Should I go ahead and replace them all or can I get some more life out of them? Tread depth is almost new. Should I go back with Goodyear or another brand? Thanks Michael

I run this size on my TT, and I can tell you, the majority in this thread have no idea what they are talking about. They run their mouth before they run a search.

For years I've looked for better tires, bigger, higher load rating, even LT rated, and they DO NOT EXSIST in this size.

Go to a 15" wheel, and you also grow the OD of the tire. There is no lower profile 15" tire that retains a near identical OEM tire diameter.

You best bet is to replace all 4 tires, because 4 years is more than enough life for TT and tires. Stick with radials. Just understand tire blow outs can occur at any time, to anyone, running ANY TIRE. Higher load rating (as long as you were not exceeding or nearing load ratings previously) does not equate to fewer blow outs. Period.

I would run max cold PSI of 50 though, nothing less. Personally, I even run a little over 50 for longer, all interstate runs where I run 65-70mph all day.

The claimed industry standard says to run more than 50psi for extended high speed travel. I did this with my OEM bias ply China bombs for 3 seasons and never had an issue but I wasn't comfortable with their wear pattern. So as of late summer, I now run Carlisle Radial trail RH which are fairly new, thus have practically zero bad reports.

The Carlisle tires have been on the road about three years now. I bought the new ones in Florida, ran them up to Maine and back out to Utah with no issues. However, I never exceeded 60mph. I can't say the same for rigs passing me at 70plus.

When you say you had a "blowout" what "exactly" happened?

Rememeber-99% of blowouts on this forum are inconclusive as to what caused them.

Sendel's email reply to me simply confirms their spec's, which appears to be shared by every other 14" and 15" trailer wheel I find. There may be a 14 or 15" wheel out there somewhere that can handle 60psi+ cold, but heck if I am spending anymore time looking!


Sendel's email;

For your question regarding air pressure it is important that you stick with our max psi of 60psi cold. When tires are run they develop heat and the pressures increase. If you have exceeded the pressure and then it increases it could possibly go out of parameters that the wheel was built and tested for.

Thanks and take care,

From the 2015 Sendel wheel catalog, the following quote regarding their wheels meeting SAE standards ( bold letters added by me ):

"Quality and Testing
These wheel brands share our high level manufacturing technology and quality principles. As a
private label manufacture that supplies many O.E. vehicle and trailer manufactures our items pass the
most stringent demands of testing. All of our wheel products have tested and been approved by global
quality and performance standards. SAE J2530, SAE 1204 and JWL are some of the most recognizable that we have passed.

For some of our recent trailer wheels we have made the extra effort in design
and manufacturing to pass both SAE J2530 and J1204 on the same wheel. To our knowledge we are
the only manufacturer of trailer wheels that offer this level of certifications. "

So what does this mean to you exactly?

Well, I dug around to find the MFG of my 14" wheels, and found they are also made by Sendel Wheel. (These guys make a TON of trailer wheels...holy crap!) They state the max load rating is at 60psi for my wheel. And their rating system is 60, 80 or 110psi and only the 110psi wheels are rated SAE J1204 certified.

Check it out...its the same story for all their 14" wheels. 60psi rating.

Kuhmo Radial 857

I put these on this past summer and could tell a significant difference immediately. Trailer tracked better and less side to side sway when we encounter high winds in Colorado. They have the highest load rating at 2271 lbs per tire and 99 mph speed rating....if you want to risk it

Another happy customer with these tires....in 2012, I had an ugly blowout with my smaller TH. Tried Maxxis, had another blowout....JIMNLIN suggested these tires and we have been happy ever since...they have two cross country trips on them (both summer trips) and several up and down the eastern sea board with no problems...they also ran quite cool through the desert. A plus side, they can go faster faster than 65...for those that like to fly at higher speeds.

These have the highest load rating in this size, but its strange. Last I shopped, which was just 5-6 months ago, they did not categorize the tires purpose as a trailer tire and I cant find any documentation that I saved showing it was available in this size that long ago. It was not listed.

Now they make it more clear, it can be used as a trailer tire, or commercial truck and comes in the 205/75 R14 size. Reports on this tire on trailers is not bad (in other sizes) but there are bad reports too, like any tire on the market. This sounds like a pretty good option, if its not double or triple the cost.


Edit: I may have omitted these from being a contender due to the 65psi rating. I could not find any confirmation my aluminum wheels could handle 65psi cold, which may be 70psi hot. The size is still puzzling me, even tire rack shows it as 205R14C vs 205/75 R14 and its very difficult to find elsewhere.

When I replaced the original China tires with the Kuhmo's, one of the first things I noticed was the weight. They are probably a good 7-10 lbs heavier that the tires I took off. To ne, this translates into more product, which can't be bad.

I replaced mine in July, and at that time, I think they were still marketed primarily at a European commercial tire, but they have since altered their website to reference trailers.

All tires have good and bad things happen, but in the few months that I have had them, I have been pleased and barring any unforeseen future issues, I will replace with the same tires in the future.

As far as the 65 PSI, the trailer came with aluminum wheels, so I just aired them up to 65 PSI and didn't have a problem. I think that Discount Tire might have put in a more robust valve stem to handle the addl PSI.

RinconVTR, I PM'd you.
