It was 70 degrees here in Alabama on Christmas eve day. My son turned 16 this year and is inheriting my 10-year-old sedan, which I've been pulling my boat with. So I bought a new car a couple weeks ago - an all-electric Chevy Bolt. One reason I chose it over other hybrids I was looking at, is I felt more confident about pulling my boat with the electric motor than with the CVT transmissions in all the hybrids. The electric motor basically has fixed gearing. The motor runs from 0 to like 8,000 RPM
I put a hitch on the car the weekend after I bought it, and yesterday (a week later), I hitched up my trailer to do some testing. When I pulled the boat out of our gravel driveway onto the street, it was all "whump, whump, whump" as I drove down the street. I drove it slowly around the block a few times to work the flats out of the tires, then pulled it down the interstate to the local airport and back. All went well - a little better than I expected! But now I think you guys have talked me into going out today and jacking up the tires.
BTW, I've also found on my TeeNee trailer with 1" axle, that the axle was bowed when I bought the trailer with my boat. It had been sitting in a warehouse for about 10 years before I bought it. Because of the axle bow, the wheels had an obvious camber - wider on the bottom than on the top. I jacked up the axle in the center and let it sit that way - one wheel off the ground - for a couple weeks, and it appeared to straighten the axle enough to take out about half the camber. Then I called out my son and he and I jumped on the tires with the axle still jacked up, and it bent the axle to get the rest of the camber out of the wheels. (Before doing this, I did take it to a couple of local alignment shops to see if they would straighten it, but they said they don't do trailers. Took it to one trailer maker, who said they would replace the axle for a couple hundred bucks.)
My boats have to go into 6 months storage each winter. I always jack up the axle to prevent flat spots in the tires. Sun accelerates dry rot too. I’m using the 5.4 x 12 .on all my trailers now. They seem to last longer.

One of the fastest ways to blow a trailer tire is to have it under inflated. This lets the side walls flex more and builds up more heat. I know someone who took their boat on a trip and blew a tire, he called me about and I said it was most likely under inflated, it just came out of storage I said check them, his reply was they look good, They can be really low on pressure and look good. Later I got another call when he got home and said they all were low. When trailering it is a good idea to also have a spare, right size lug wrench, a jack that fits the trailer and also a spare set of pre packed wheel bearings and the tools to change them. Get in the habit of each time you make a stop of checking the temp of the bearings.
