19.5 tires on a drop deck, do they hold up?

I looked at that option but decided on 17.5 instead for the extra inch. The 17.5’s seem to fit really well in Pennsylvania’s potholes. Better carry a mounted spare

 

I have never run the 19.5's, but tehy sure can't be worse than the 17.5's. Actually there is 3 different sizes of 17.5's, I had the smallest on one stepdeck, and they would sure change your driving habits, they ween't made for speed. lol
They were also not made for rough roads, I bought that trailer to run back and forth from all over the states to Alaska, and the rough roads (I think) would break belts in the tires) half way or better around the tire would look like new, and the other get right down to the wire, generally at lest one per trip.
I think if I would have put the largest 17.5's, which if memory is right were 235 r, I would have had better luck and maybe even pulled that trailer more.

 

At 75 mph those little tires (and bearings) think it's 90 mph if I remember my math correctly from when I figured it out.

 

Yep, I could max out on weight or even be over and they would hold up fine, they just wouldn't take speed. I was reminded of the old tube type bias days. lol

 

Not to mention, that the only available 17.5 at a petro or ta is a bridgestone 6 series going for right around $700

 

Had 19.5 on a 53 step with slide axle.
Never had any real problems. Wear was about the same as 22.5’s

 

I had a step with 19.5. tires didn't last as well as 22.5/24.5.
I traded that trailer for a step with 17.5. I don't think I ever got a full year out of a tire.
Weight didn't matter much. Speed over 62 during the summer, especially in the south did.

I just traded that step for one with 22.5.
Hoping to lower tire cost. Just haul shorter oversize.
Good luck and carry a spare.

 

We’ve had good luck with these. We have a 2008 and a 2012. Also have a 2018 with 17.5 and a sliding rear axle that we don’t use unless we have to because it’s harder on tires. Last I heard they hadn’t figured out how to slide an axle with the wheel wells

 

Rank, what size 17.5's are you running. Mine had the smallest iirc they were 215 r 17.5 I belive they also have 225 and 235, I have heard the 235 's work much better.
