At first glance, trailer tires do look a lot like light truck tires, but they have some pretty important differences in how they’re designed and constructed. They often have much higher inflation pressure too, making it easier for them to handle heavier loads for towing. Trailer tires have a whole different set of stresses and loads, and that's why tire makers specify that light truck tires aren’t suitable for use with trailers, and trailer tires should never be used on vehicles. The Green Max GM R781 is a budget-priced trailer tire that is a great fit for camper trailers and light industrial use and is available in a variety of sizes and load ratings for your application. Let’s go in for a closer look at this Green Max GM R781 review:

SimpleTire’s view on Green Max GM R781 tires

Are you familiar with SimpleScore? SimpleScore is the proprietary rating system that the SimpleTire team developed to give you a quick, at-a-glance idea of a tire’s strengths and weaknesses. We look at the tire’s technical details, manufacturer info, specs, customer reviews, and other bits of information, then we process that all to a 1-10 numerical value for the categories of traction, durability, and longevity along with an overall average SimpleScore. In the case of the Green Max GM R781, the SimpleScore numbers break down like this:

Green Max GM R781:

• Traction: 7.2
• Durability: 8.6
• Longevity: 7.2
• Overall average SimpleScore: 7.6

The Green Max GM R781 would make a great choice for light to medium trailering duties. The GM R781 is designed for easy, stable towing at highway speeds (the M speed rating is quite a bit higher than what many trailer tires offer), and the tread pattern enhances straight-line tracking with minimal tendency toward trailer sway or wander. Wet-weather performance is good, as the Green Max’s four wide circumferential grooves are designed to resist hydroplaning by quickly routing water away from the tire’s footprint.

With a ply rating of up to 10, the Gladiator QR25-TS would be a great selection for larger, heavier camper trailers. Its combination of steel belts, a polyester casing, and nylon cap ply give this tire great stability and handling at highway speeds. The ozone-resistant tread formulation is a great feature too, when you consider how many trailers spend months outside in the weather and may not be driven very frequently. Like all trailer tires, the Green Max GM R781 is purpose-built for towing duties and should never be mounted on vehicles.
