Difference in trailer tires..

I didnt make myself clear, but I was specifically asking about 7 x14.5 tires that are approved by DOT for Highway use... I has always thought you could only get these tires for 'mobile home use only', but obviously if Hudson is selling new trailers the tires have to be approved for such..
thanks for the feedback..

The contractor I work for has a couple lowboy trailers with the 14.5" tires. They're highway approved, NOT mobile home tires. Not that common, but available apparently

Pretty sure that most trailers have springs to absorb impacts. The shock just prevents bounces, right.

According to Monroe, the people that make a large percentage of modern shock absorbers, they dampen shock released by the springs as a reaction to sudden compression or de-compression. Springs will not "absorb" impact shock. They only re-direct it The energy that a spring absorbs is released when the spring rebounds. Shocks, as a result of absorbing that impact, keep tires in good contact with the road, as well as takes away some of the recoil effect of the spring that would also be sent through the vehicles frame.
Springs and/or tire sidewalls don't offer the smooth dampening effect that a hydraulic shock can.

Me, too. /forums/images/graemlins/frown.gif On the round trip to Alaska and back in '72 with me pulling a travel trailer, my parents pulling a travel trailer, and an aunt and uncle with a pickup camper, we experienced 17 flat tires. /forums/images/graemlins/tongue.gif Then my '89 fifth-wheel trailer came with ST (trailer) tires, but they were bias ply. I made it all the way to Anchorage with it in '90, but found when I got there that two of them had big bubbles in the sidewalls. I believe the first radial trailer (ST) tires were made by Goodyear in '89 or '90 and I put them on the fifth-wheel when we got back south. Goodrich came out with their own radial ST tires in '91 while I was back in Anchorage working at my brother's tire dealership. Personally, I wouldn't even consider bias ply tires on anything that was going to be used very much because the radials will last enough longer that they're cheaper in the long run.

Thats the way it goes here, Brian. Hijacked threads is a risk you take.
In my post I was referring to DOT approved Powerking brand LOWBOY tires
but I have to add the more favorable HD version only came in 8-14.5 still you cannot find a 2800 lb load tire thats as small as a 14.5.
Oh did I mention to buy american or canadian made tires /forums/images/graemlins/laugh.gif /forums/images/graemlins/wink.gif /forums/images/graemlins/shocked.gif /forums/images/graemlins/smile.gif /forums/images/graemlins/grin.gif /forums/images/graemlins/blush.gif /forums/images/graemlins/grin.gif /forums/images/graemlins/blush.gif /forums/images/graemlins/smile.gif

My previous trailer was a 14' Hudson tandem axle. It had 14.5 tires on it. Here is a link to a place that sells the tires. Click Here They are used to give a lower trailer.

which tires are the ones that are like max psi of 100psi? My trailer was bought used, no rated weight, well it was on paper as 2000lbs lol but i guess the builder did that for registration purposes, the previous owner had a 9400lb loader on it a few times and he said it rode great.
My 3600lb car doesnt put a dent in what this thing can haul, its a 16ft long dual 7k axles open car or equipment trailer.
My dumbarse was pulling the car around with 40~ psi in the tires till i realized my 91 f150 was really struggling on highways to pull this thing along lol, Here it should be at at least 60+PSI for 3000lbs or more. I tested the used tires to 85psi and they seemed fine just rode hard for the weight on it at the time.
Ive seen other 5200lb dual axle 24ft enclosed triailers that have "car" looking 15" tires?
