What is the tyre pressure for a 155 70 R13 trailer?
What tyre pressure for a 155/70 r13 trailer or car with the same tyre size? The optimum tyre pressure for 13-inch tyres, on popular car or trailer models, varies between 2. For the rear, the values are slightly different, ranging from 1. Did you know your trailer type can impact your recommended tyre pressure? For instance, traditional trailer tyre have a psi of 35-44 on sealed roads, while boat trailer tyres should be around 50 to 60 psi.Should trailer tires be inflated to max psi? trailer tires should be inflated to the maximum inflation designated on the tire’s sidewall to reach full load carrying capacity. Remember, the air within your tire is actually carrying the weight!They are also typically speed rated to 65 mph max so highway speeds are perfectly doable. We recommend looking at our blog on the truth about trailer tires for more information! Safety tip: always make sure your trailer tires are aired up to their maximum rated pressure (you can find this on the sidewall).Car tires simply aren’t built to handle trailer-specific stresses. The thinner sidewalls cannot support heavy trailer loads or resist swaying forces effectively. Load ratings on car tires are calculated for vehicle frames, not trailer frames, which distribute weight differently.
