The trailer I pull is 13K loaded when it comes time to change can I go with a lighter tire?

Kind of funny when they unloaded this truck from the transport I was there and took it on the spot...Had a "A" plan so still was under what a 250 list for.....

 

I guess that's entirely up to you. I don't know what load ranges of tires are made that fit 19.5 inch rims. But if you're pulling only 13K, you could easily go with a load range E or D.

 

Thanks for the info!

 

The lightest load range you will find for 19.5" wheels is Load range "F" (12-ply) your truck came from the factory with Load range "G" (14-ply).

The 225/70R19.5 tires have these load ratings

F = 3640lbs
G = 3970lbs

Without weighing your truck & trailer loaded ready for travel at a CAT scale you will not know the actual load on your rear axle and tires. Weigh your rig and then you will know what load range tire you need to run.

One other thing, most tire websites list air pressure table for commercial tires, so when you are empty you can air the tire down for the lighter load.

Here is the link to the inflation tables on the Continental Commercial tire website.

Wonder if this would help with the wondering on grooved pavement?

 

Maybe, you can try it, off road tread patterns always track a little worse than a highway rib on dry pavement. Lower air pressure should make the ride a little smoother.

 

You can visually tell the difference between the tires. The one's on the F450 & F550's look much more like the commercial truck tires. And looking at the grooves, you can wonder why they track the way they do on those surfaces.

 

What kind of tire is the THB max traction option? what is the load rating?
