Best size tires for a 4'x6' utility trailer for long freeway trips

[Li'l Work Truck]

Yes, Dexter. The Lowe's website confirms your suspicion. 5x4.5

What do you do about the diff?

Leave the oil in and let it spin. Or remove the spider gears.

If you leave it to spin, have it turned around backwords and rig up some LED lights on the pinion flange. That'll distract the drivers behind you.

My reason for trying for the same tire and wheel as your truck is so you only need to carry 1 trailer spare. The truck already has one.

Rig up alternator to pinion. Wire to inverter. Hook inverter to charger on EV. Perpetual motion achieved.

Always remember…
If you do match the vehicle tire size, never run a P series tire on a trailer. You can run an LT tire in place of an ST tire.

I get the statement, but what's the reasoning? Are the P tires to low of a weight rating for trailer use?

Normally there are tons of axle options at tractor supply. Then you can get the axle with the hubs in it already and probably get the bolt pattern you want.


Just unbolt that axle and bolt in the new one

Wag...
It probably doesn't matter on a single axle trailer, but dual or triple axle there is a lot of side force when turning corners. I believe there are more cords on the ST sidewalls, and probably the LT.

Yes, It’s about sidewall strength. P series tires are weak.
Will they work?
Probably. How long will they hold up is the real question. I’d rather go with something that’s well documented within the offroad trailer community to hold up to the side loading that a trailer tire sees. P series tires on a trailer are know to fail.

I had considered that, but I probably won't be keeping this trailer long term. I want to build or modify something that'll easily carry 10'-16' long construction materials, but not be full sized and too heavy. Maybe an 4' to 5'x 8' to 10' basic utility trailer that can be temporary expanded in length. I've got another trailer without paperwork that I'm going to look into getting registered down the road. I'd like to have a trailer with electric brakes and maybe dual axles.

Aren't the stiffer sidewalls on LT rated tires more resistant to swaying and being jittery?

A single axle trailer doesn't see side loading. Not any more than any vehicle already on the road.

The answer to that is "boat trailer".

The side loading on a single axle isn’t from the twisting as much as it’s from sway. All trailers sway, there’s no way around it. The LT tires will handle sway like an ST. The Ps won’t.
Is it worth it when a ST tire on a rim is about the same price as a P tire without a rim.
