Jack,
For whatever it's worth, this excerpt was taken from page 43 of the copy I have of the current Good Year engineering data book:
"LT — Light Truck tires for service on Trucks, Buses, Trailers and Multi-Purpose Passenger Vehicles used in normal highway service. "
To me, the way I read that, they are approving the use of their LT tires on trailers. It does not mention any restrictions on any given LT tire of any size in their range. This data book covers all of their brands ( Good Year, Kelly, Dunlop )
Again I am not trying to discredit the tire or ones chosen use of the tire… it’s the tire builders ducking and hiding from that use that concerns me…
I have read tons of literature from GY and on GY, though it’s been some time now I have spoken to them on the phone and by E-mail… also to Maxxis and Carlisle by phone and e-mail, and Continental by e-mail only… I know what they told me and what is available in the US market… I have also searched the catalogs of the aforementioned as well as Toyo and Yokohama…
So other than the Marathon’s from GY what is available for trailers or RV trailers from them … here is a result of a search on the GY website… no boxing anyone in the corner here…
Your Search Criteria: Application: Light Truck: Wheel Position: Trailer Tire Size: LT235/85R16 G (only size available) G614 RST …
There are 1 tire(s) based on your search criteria: G614 RST: Position: Trailer
LT235/85R16 G: 75 SPEED RESTRICTED: MAXIMUM LOAD 3,750 POUNDS: 110 PSI…
Again not a typical TT tire…
Some standard language used by a lot of tire builders like GY…Yokohama version of the same language… “LT Identifies a light truck tire for service on trucks, buses, trailers and multipurpose passenger vehicles for normal highway service and to be used on a five degree tapered bead seat or on a 15 degree bead seat rim. “
But then Toyo version,
“TIRE TYPE: Tires with a “P” are for passenger car use. Some passenger car tires may not have a “P” and are considered hard-metric tires. Some light trucks and SUV’s are equipped with original equipment P-metric or hard-metric tires.
Tires with a “LT” are for light truck or SUV use only. “
