Due to a recent run in with a fence post I got to buy two new tires for my car trailer. So now I have two nearly new load range D tires rated at 2500 pounds and two brand new load range E tires rated at 2800 pounds. I'm thinking I should run one of the new tires on either side of the trailer but I have a few things to ponder on. The trailer is a 20ft 10k pound car hauler that's loaded to max weight quite often.

-Would it matter which axle front or rear. Don't the fronts tend to scrub more on a tight corner?

-Since the LRE has a stiffer side wall and doesn't squish as much will this transfer more weight to the softer tires causing them to run hot?

I'm probably overthinking this but I have tendancy to do that

Did you have to get different lug nuts?

I didn't have to, but I did. The OEM ones were open and steel, the new ones are closed and chrome.

That my next project I need to get new rubber on the truck and trailer. Quote from my tire guy in Ontario, OR is about $680 for the truck and $400 for the trailer.
