Make sure to choose the right tires for your specific application.
Due to their affordability, many trailers come with bias tires. Radial tire are often an upgrade.
Bias tires heat up faster than radial which makes them suitable for local driving.
If you are going to tow your trailer beyond you local area, you should consider upgrading to radial tires.
If you choose the wrong tires, they could rupture from overheating and leave you stranded beside the road far from help. Ruptured tires can cause damage to your trailer and cause you to lose control of your vehicle and your trailer.
If radial tires are better, why do they put them on trailers?
The trailer business is very competitive. The added cost of radial tires will cause many buyers to ignore ads with a slightly higher price. They will not get the opportunity for a dealer to explain why their price is a little more and the benefits and danger of not purchasing the right tires for their trailer.
