Many tires are branded with LT in the name, or marketed as a LT truck tire and come as OE tires on light duty trucks but are really only P rated tires… a Wrangler RT/S might be an example and comes in sizes P235/75R15 105S --- P255/70R16 109S --- P265/70R16 111S…
Or the Michelin LTX® A/T2 Light Truck tire might be a P235/75R15/XL 108 S or a P275/60R20 114 S …
but they are still P rated tires not LT tires…
And they need to be derated for use on trucks SUV’s or in trailer applications… marketing won’t change the facts…

“Until the arrival of the global vans, the Euro-metric commercial tire sizes were “incredibly limited,” according to Mr. Rastetter.
Mercedes-Benz North America recently introduced its Sprinter Euro van.
Some tire makers have listings of such tire sizes in other markets, but Goodyear declined to comment on the issue and Continental said it will be introducing a 16-inch rim diameter all-steel-belt tire for the pickup and delivery segment in the U.S. in 2015.”
“Chrysler appears to be planning to address the issue after it began shipping the 2014 Dodge Ram ProMaster late last year to the U.S. The vans are fitted with Continental tires in size P225/75R16C but will transition to Nexen brand tires later this year, the auto maker said. “
The commercial van tires as they were originally known by are Euro Metric tires with a new commercial designation and higher load capacities and higher air pressures… they were initially manufactured for and marketed for use in countries other than the US… their introduction into the US has largely been done by third party sellers and not the Manufactures themselves who still resist importing to the US…
Metric / Euro-Metric -- 185/65R15 88T
Metric tires, also known as Euro-Metric tires because the sizing originated in Europe, don't have a letter designation. Euro-Metric sizes are equivalent to P-Metric sizes in dimensions, but Euro-Metric sizes have subtle differences in their load-carrying ratings and capabilities. Euro-Metric tires are usually found on European cars, but they're also used frequently used on SUVs and vans.
C = Commercial
Euro-Metric tire sizes ending with a C are commercial tires, for use on delivery trucks and vans capable of carrying heavy loads. In addition to the C designation, these sizes are also branded with a load range or service description rating…
they are P rated tires on steroids JMHO…
Per the tire rack, “Three tire-sizing systems are used on the Original Equipment (O.E.) tires fitted to today's light trucks, Euro-metric, P-metric ("passenger" metric) and LT-metric ("light truck" metric)… 1/2-ton vehicles use Euro-metric and P-metric sized tires, while some 3/4-ton and 1-ton vehicles use LT-metric sized tires.”
Say what you will the commercial tires referenced ARE Euro Metric tires…
they are close relatives to the P and Euro Metric tires, and are heavy duty replacements for the standard or XL P and Euro Metric rated fitments…
