Maxxis ST Radial M8008 Trailer Tire Test ReviewPosted in How To: Wheels Tires on December 14, 2016
We’ve put several thousand miles on the Maxxis ST Radial M8008 trailer tires without any issues. Our car hauler weighs in at about 1,500 pounds and regularly carries a 4x4 that weighs about 5,000 pounds, for a total of 6,500 pounds of rolling mass. Anyone that’s regularly towed his or her 4x4 cross-country on a car hauler has likely experienced a trailer tire failure. Understandably so, there are many different things that can cause them to come apart like a Cinnabon in a blender. These include sun damage, old age, overloading, low tire pressure, impact with a foreign object, and so on. The thing to remember is that not all trailer tires are equal. Some trailer tires are of a better quality, more robust, and more UV-resistant than others. Also, radial trailer tires roll more smoothly, run cooler, and wear longer than their antiquated bias-ply counterparts. Having had more than our fair share of trailer tire failures, we are happy to report that our Maxxis ST Radials haven’t even whimpered from our trailering abuses and appear to be wearing incredibly evenly after two years of service.
A typical car hauler trailer comes with a pair of 3,500-pound-capacity axles. To cut costs, they often come with passenger car tires mounted on 15-inch-diameter wheels. These tires are usually not up for cross-country hauling a 4x4, as evidenced by the overly bulging sidewalls under the heavy load. That’s where the eight-ply Maxxis ST Radial M8008 in 205/75R15 flavor comes into play (part number TL15703000). This tire features a D load rating with a max load capacity of 2,150 pounds. Watch out though, as there is also a less desirable six-ply version with a C load rating and a max load capacity of only 1,820 pounds. The fenders and frame on some trailers will allow for the much larger 225/75R15, which comes in both an 8- and 10-ply version with 2,540-pound and 2,830-pound max load capacities, respectively. The higher load rating and increased air pressures help keep the tires cooler under a given load and allows them to last longer. However, make sure your wheels are rated for the higher capacity before mounting up your new Maxxis tires.
