Trailer tire pressure

[jkbstingray]

1900SCR, what PSI are you running in your trailer tires? I normally don't fret this too much as we're 8 blocks away from the boat ramp at 35mph. But we're moving next week and I will be pulling the boat 275 miles at highway speed. Single axle, tires are rated at 80psi cold. I check mine and currently have 60psi. Will that work, or do I need to adjust?

Thanks!

Unless you know exactly what your boat and trailer weighs, there is no way to know what tire pressure you need. Go with the max of 80 psi cold and you'll be safe. Always use the sidewall inflation pressure unless you know the load on the tires.

Concur.

Ok, thanks y'all. I'll just pump them up and go then. Sounds like a plan!

The other important issue with trailer tires is age. Trailer tires usually age out before they wear out. Trailers sit more than they roll. Tire rubber degrades faster when it is not ‘massaged’ via rolling. My rule is 5 years old, replace them. Some go 7 years. Kinda depends on load on the tire. Most trailer tires are run at close to max load rating so age has the greatest effect.

Yessir! These are only 2 years old... when I bought the boat I towed it about 60 miles to get it home. When I got home and checked the tires, they were so old there were literally chunks of rubber breaking off of them. It's a wonder I made it home!

I would also repack the bearings if they haven’t been done in a while.

Yep, just done last week. Great suggestion though, thanks!
