Expedition Trailer Tire Selection
OK so when I bought my M416 & was bringing it home the tires were dry rotted & were leaking so fast I had to stop & buy tires
I was forced to purchase trailer tires according to the shop rules (tirewarehouse) & they offered me ST tires however I wanted LT tires
I wanted aggressive mud tires for the trailer
so doing some research about this [since it still bugs me] I found:
Itrailer mentions, "There is an ongoing debate as to whether LT or ST tiresare the best option. LT stands for Light Truck-metric. LT tires can carry a substantial load and are used not only for trailers but also for full size vans, SUV’s and pickup trucks. LT can typically carry up to two thousand pounds of weight. ST stands for Special Trailer Service. ST have been specifically made for trailers and RV’s and are usually cheaper than LT".
TireRack claims, "Your trailer is a follower, which often makes tire sidewall flexing a negative. Sidewall flexing on trailers, especially those with a high center of gravity (enclosed/travel trailers) or that carry heavy loads, is a primary cause of trailer sway. Typical passenger radial tires with flexible sidewalls can accentuate trailer sway problems. The stiffer sidewalls and higher operating pressures common with Special Trailer (ST) designated tires help reduce trailer sway.
Also consider that Special Trailer (ST), as well as Light Truck (LT) tires are fully rated for trailer applications. This means ST- and LT-sized tires can carry the full weight rating branded on the sidewalls when used on a trailer.
However when P-metric or Euro-metric tires are used on a trailer, the load capacity branded on the sidewalls must be reduced by 9%. This means P-metric or Euro-metric tires with a maximum branded load rating of 1,874 lbs. for use on a car is only rated to carry 1,705 lbs. when used on a trailer".
Ok so the sidewall is stiffer, one good thing I guess
What really angers me is this:
Discount Tires states, "Speed
All "ST" tires have a maximum speed rating of 65 mph.
As heat builds up, the tire's structure starts to disintegrate and weaken.
The load carrying capacity gradually decreases as the heat and stresses generated by higher speed increases".
& now I need not speed, not that I do
so lesson learned on my part
