Changing Tires.... Bias Ply or Radial

[tizfun]

Hey there everyone... In need of some advice from anyone who has changed over from Bias Ply to radial tires on their boat trailer... I've come across some nice aluminum rims for my trailer and looking to put some tires on them.. I currently have ST185 13D (Load range C Bias Ply) on the factory rims from Shorelander.. Should I go with the same type of tire for my new wheels or go Radial.. The radial will be the same size 8 ply.. I'm concerned about the sidewalls and whether the radials will give me a good tire life.. Anyone swapped over to radials ?? If so, how have they been for you ??
I'm just not sure about the radial tires.. Even though they are cheaper..

Radials for sure. And balance them.

13's are limited to Maxxis for a quality tire. There is no Chinese tire that is quality in 13" size. Goodyear's new ST tire does not come in the size either.

Went to a trailer shop and they are offering Kendall in bias ply and Velocity in the radial ??? Not sure either of the brands...
