TIRE TIRES TIRES
Does anyone have any information from the tire manufacturer why we should use trailer tires instead of truck tires on trailers? If all the side wall ply and tread ply are the same, what is the differe...

reaction to above.
I did not state that ST tires álways have stronger sidewalls but if done it also influences the heatproduction.
My believe is that some ST tires are as LT tires constructed and set in the market as ST with higher maximum load calculated for the more deflection allowed for lower speed.
Also ST tires are in the market with 35 psi AT pressure , and I suspect them to be constructed as P-tire and set in the market as ST, with at most a bit lesser profile.
For Motorhomes in Europe , where I live, Continental and Michelin and mayby also others, have Special camper tires with given as information stonger sidewalls. Most are D-load/8PR with AT pressure of 4.8 bar/69/70 psi, wich is a bit higher then USA system 65 psi, to my conclusion to compensate for the more heatproduction because of the stonger /stiffer sidewall.
Michelin prints maximum pressure of 5.5 bar/80 psi on it, the same as standard load and XL only give maximum pressure.
Continental calles them Vanco camper tires.
They give maximum load xxxx kg/lbs AT 69 psi ( cold) but also maximum allowed pressure of 80 psi/5.5 bar .
Also they often give a second loadindex for other maximum speed, the same as is done on most truck-tires in Europe.
Sometimes higher speedcode and lower Loadindex , other time lower speedcode and higher loadindex given.
But also for these camper tires , I suspect them to be only slightly different then the normal C-tire ( Eur for LT).
