Trailer tires vs regular tires
I've heard that you can use regular tires on campers as long as you get one load range higher.Any input on this. Thanks

As has been said : As a general rule P or passenger car tires are not a good substitute.
The load rating (in pounds ) posted on the sidewall of "P " tires must be derated by 9 % .
What sometimes happens is somebody has a " take off " tire from their pickup that has P rated tires and they mount them on their RV because their RV tires are "cracked " from the sun and ozone .
Then the P tires fail because they do not have adequate load reserve capacity , either .
As others have said an ST or LT tire with additional weight capacity in pounds is the cheapest way to prevent tire failure .
Presuming that you have load range "C" tires max 50 psi, now :
If you buy a load range D tire you can pick up 10- 20 % in load rating in the same size tire . If you inflate to 65 psi as shown on the sidewall you pick up reserve capacity .
Further , even if you miss an inflation check and your tires deflate from 65 psi to 50 psi you still have the same load rating as the C tire at 50 psi.
