I have a camp trailer and I put car tires on it ,did great for 2 years then got into a wind storm and the tread came off
you have a obd2 system. and when the check engine light comes on there is a malfunctioning code. You need to take it to a mechanic if you can't diagnose it yourself.
Yugie29 is right, the actual code would be useful if you had it. However, I would try to unhook the air conditioner either from the fuse box or from the connector, as I am thinking you could have a short. I would also check the climate control switches. Good luck!
One key difference we need to think about though is the intended use. An automotive tire (if you listen to the vehicle manufacturers) is there to give you a soft comfortable ride. To do this they have lower air pressure and softer side walls which flex a lot. Trailer tires on the other hand are meant to carry a load. If we follow the 32 psi rule, the trailer tires side wall will flex too much and quickly overheat, possibility leading to a tire failure. More on tire pressure is a little further on. A big difference however lies in construction of the tires. There is a huge difference in the plies and belting of automotive tires versus many trailer tires. There is also a huge difference in trailer tire between manufacturer's and some are just down right garbage.
Trailer Tires Vs Car Tires
Apples and oranges. Car tires do not have the load bearing capacity of trailer tires. Your trailer has a specific trailer tire recommended predicated upon the axle weight and tire needed to do this efficiently(tread, number of plies, etc.). Car tires are not designed for trailers. Every tire has a purpose predicated upon weight, heat and friction. Not to sound a jerk, but you wouldn't put trailer tires on your car or truck, right? Different purpose under a different circumstance. Trailer tires are for load bearing, car or truck tires vary in need for a particular circumstance. You need trailer tires for your trailer, just as you would for off road tires for a off road vehicle or performance tires for a performance car on the track or street.
