Skip, Maxxis makes tires in China too you know. I had 2 sets of Maxxis made in China. They may just have a better handle on quality control.

FWIW, I had treads cracks at age 4.5 year on both sets. 5 years is it for sure on these things.



J

All Maxxis M8008 ST radial tires are mfg'ed in Thailand per Maxxis...

There apparently was a time when they were made elsewhere, but for now they are not, some of their auto and LT tires are made in their china plants…



Hi JJ,

Good to see your email note from Maxxis. It appears Maxxis has shifted what tire they make where over the years. He did not say they where never made in the China plant. Skip was talking 10 years ago and I was responding to that 10-year-old statement and that he would never run a China tire and always Maxxis.

This much I know as I had them, at least between Oct 2003 and June 2004 (maybe more, maybe less) Maxxis ST 15" C load range and load range D where made in China as at least one of their manufacturing plants. I had a set of both with the stamp in the tire side wall.

I also have a camping buddy who had a set of Maxxis 15" load range C out of the China plant that was now about 3 years ago. For reasons not known, he ended up with really bad thread cracks after 2 years.... I was shocked, he was ticked.... he now has converted to LT's.

So from your note it now seems that somewhere after 2007/2008ish period that all ST's have been moved to Thailand plant. Prior to that, they may had been made in multiple plants in different countries with the China and Thailand plants being two of them.

The country does not really set the quality of the tire, the company running the product in that country does. If the company making them ends up with junk being shipped, their name just sent down the toilet. In this day of uncertainty of ST trailer tire quality, Maxxis seems to be the leader in better quality control. After seeing my buddies Maxxis tires some how they slipped through the system. 2 years from now I will be faced with this issue and if I stay with ST, right now Maxxis would be it.

Thanks for passing along your note from Maxxis.

This looks like as good a place as any other to insert this little tidbit.

Tire retailers SELL tires to stay in business. When a buyer shows up with a rim/tire in hand seeking replacements, some of the important safety factors will be overlooked. That’s when the buyer really needs to know what they may get themselves into.

The DOT has made every effort to insure the buyer has the information needed to make a wise choice in the selection process. All sorts of information is molded right into the DOT certified tire sidewall. In the reference below you will find just one of them. A tire retailers installer will often overlook that information when installing tires other than the OE replacement size.

Earlier - page 3 - I posted a reference about the Maxxis Corp. Their newest Mainland China plant and test facility is independently owned by Maxxis. From that, I assume their ISO certification in China is equal to the one in Taiwan.

The tires I mentioned in the post I simply asked the guy at pep boys what the closest thing he had to 225/75r15 were in lt tires. These were them. Again. I am still confused. The load rating for these tires are similar to the ST tires currently on the trailer. Combined they will have around a 10k capacity, which for my TT is fine. I think. My gvwr for the TT is 7500 lbs and I am around 6500 ready to camp.

I just need to measure to make sure the 235's will fit

Ok experts. Tell me how this tire looks.

Dakota HT LT235/75r15


It's an lt tire and increases the tire size from 225 to 235 but it is an LT tire in load range C.

The tires are $140 ish each.

I think they will work for my application but I wanted to run it by everyone here. I just want the best tire I can get for my money and I want to avoid the tire troubles. Lol

Thanks!


They don't give detailed specs on it like what the load capacity is at it's rated maximum pressure. Just based on what I see there, I'm not impressed.
But then I'm not an expert !

Keep in mind that Passenger (P) tires ARE used as Origional Equipment (OE) on some trucks. When using a P tire on the RV trailer it's load capacity MUST be divided by 1.1 to get the devalued load capacity.

RV trailer tires are selected by the manufacturer to meet the minimum DOT requirement. That's the certified rating of the trailer's installed axle (s). In other words, axles rated at 3000# must have two tires rated at 1500#. It's best to add at least 12-15% to that figure to provide some reserve load capacity. So, find your trailer's axle certification label, divide by two and multiply by 1.15 to get the desired load capacity. Then look for rims/tires that will fit.

Many tires have LT in pretty raised white letters on the side wall but they are P rated tires…



We have to first separate the issues involved… the tire problems, and the country of origin are two distinctly different problems, but both are real problems… the second has a effect on a host of products including tires…

The ST tire problem is the low certification standards they must meet and the demand for cheap trailer tires… its really that simple, they are allowed to build a sub standard tire for trailer use… (that doesn’t mean they have to…)

Even tires carrying the DOT certification doesn’t mean it is a safe tire… it only means the mfg has certified that they have been tested and have met the certification requirements… but this is where china made tires come into question because they are out of reach of the US regulators…

What you don’t know can kill you when it comes to tires… Ask the importers of Westlake LT tires a few years ago…

(snip)
In June, Foreign Tire Sales appealed to NHTSA for aid in recalling an estimated 450,000 light truck tires sold under the names Westlake, Telluride, Compass and YKS after the company allegedly learned that the manufacturer, the Hangzhou Zhongce Rubber Company, had left a critical component out of the tire.

But the number of defective tires could be much higher, FTS told NHTSA, because Hangzhou has refused to specifically identify by Tire Identification Number, which tires are missing or were built with an insufficient gum strip - - a feature that helps to keep the tire belts from separating.

The Hangzhou tires join tainted pet food, lead-coated children's toys and toxic toothpaste as some of the latest Chinese imports deemed hazardous to American consumers. According to the New York Times, Chinese products now account for 60 percent of all product recalls today.
(snip)

If I remember the Chinese mfg never accepted responsibility in the matter and it bankrupted the American importer…




Chinas quality or should I say lack of it are legendary, historical, and well known to importers and mfg’s alike…

Paul Midler founder and president of outsourcing and supply chain management services firm China says it best, a 15-year veteran of dealing with thousands of Chinese factories he should know what he’s talking about… He describes how Chinese politics and economics lead to management attitudes that drive quality fade…

snip:
"quality fade." This is the deliberate and secret habit of widening profit margins through a reduction in the quality of materials. Importers usually never notice what's happening; downward changes are subtle but progressive. The initial production sample is fine, but with each successive production run, a bit more of the necessary inputs are missing.

Snip:

In early 2010, somewhere high above the northern hemisphere, Mark Krywko decided he’d had enough. The CEO of Sleek Audio, a purveyor of high-end earphones, Krywko was flying home to Florida after yet another frustrating visit to Dongguan, China, where a contract factory assembled the majority of his company’s products. He and his son, Jason, Sleek Audio’s cofounder, made the long trip every few months to troubleshoot quality flaws. Every time the Krywkos visited Dongguan, their Chinese partners assured them everything was under control. Those promises almost always proved empty.
As he whiled away the airborne hours, Krywko made a mental list of all the manufacturing glitches that had nearly wrecked his company. There was the entire shipment of 10,000 earphones that Sleek Audio had to discard because they were improperly welded, a mistake that cost the company millions. Then there were the delivery delays caused by the factory’s lackadaisical approach to deadlines, which forced the Krywkos to spend a fortune air-freighting products to the US. Even when orders were produced on schedule, Krywko wasn’t too pleased with the situation: The company always had precious cash tied up in inventory that took months to arrive after the prototypes had been approved.
One reason for abandoning China is quality: Some products are too flawed to sell.
The headaches had finally become too exasperating to bear. And so, on that flight, he turned to Jason and said that he was done with Dongguan. “I can’t do it anymore,” he said. “Let’s bring it home.”
Jason had been thinking the same thing.

With three blowouts with camper damage and replacing tires with the start of core separation(bulges)all were ST tires from three different manufacturers. The first blowout was the tires the camper came with and were LR-C. The remainder of problems were on LR-E tires in an attempt to not have problems but even the heavier, higher belt count ST tires failed. Blow a tire on the first camping trip of the Summer and you were out of commission for over a month for repairs.

I switched to LT 16" XPS Rib tires and have not had a single tire failure. I would never go back to ST tires.

I will probably switch to these when they hit the market from Michelin.

I think one thing to keep in mind with trailer tires is this:

When you have a tire going down in your car or truck you'll know it, you'll hear it and/or feel it. With a trailer, those tires are 20-30 feet behind you, you can't see them, definitely can't hear them or feel one going bad on you so I don't think you want to take a chance on putting cheap tires on your trailer, by the time you know you have a flat or a blow out it's too late, the damage is done.
