I am continuously having flat tires on my trailer due to picking up nails, screws etc.

Usually its in the rear trailer tire. I am tired of fixing or replacing tires.

Someone recommended to buy 14 ply tires and that would stop a lot of the flats, expecially when I pick up a nail in the sidewall.

I have a 4 hrs with a 5' shortwall. Currently running 10 ply load range E tires. (BF Goodrich).

Can someone recommend a 14ply tire or other options I may have.

Thanks

Don't think these are yet available in trailer sizes.
