Trailer wheel balancing question.

I have been told that new campers are fitted with cheap bias ply tires and are not balanced from the factory. My tires were worn unevenly so I bought new radial tires and had them balanced. So far they are looking good and I am sure they dont shake or vibrate. If I ever ordered a travel trailer I would make sure it came with balanced radial tires. Even if you put new tires on yourself the cost to do so is well worth it. If I remember correctly it was less than 60 dollars a tire mounted and balanced.---Be sure to protect your new tires from the sun with tire covers.
