Big Snip
Remember: If you go for passenger car or LT (Light Truck) tires
instead of the ST (Special Trailer) tires, you have to add 25% extra
load, usually bumping up two notches on the Load Rating scale from a B
to a D or E. That usually removes the financial advantage of using
passenger or LT tires.

Another Big Snip

ANd if you are planning on putting passenger tires on a trailer, take
the rims in and DO NOT tell them they are going on a trailer. Don't
know about where you are, but no tire shop up here will install P
rated (or even LT) tires on a trailer _NO WAY.

And just a word of advice - don't waste your money putting P rated
tires on a trailer anyway. Can make an otherwise well behaved trailer
into a towing nightmare - while ST tires can do the exact opposite.

Well, if you are out in the Sticks and need a tire *now* to get
home, it's safe enough to use LT Tires in a pinch - but you HAVE to go
a lot heavier than the ST tire that the load of the trailer calls for.
You're right, those P-Metric floppy 'soft ride' sidewalls and sticky
'corner like gumballs' tread will have that trailer dancing the Watusi
as you go down the road if it isn't loaded perfectly - especially the
cheap ones. Which is why you go the other direction and use the
12-Ply (Load Range E) or higher truck tires. Something nice and
stiff.

If they flat out won't sell you tires, they're stupid. A true
businessman will always find a way to make the sale, not find excuses
to NOT make one.

Reminds me, I have to call Costco Corporate and see if they are
really in the tire business or not.... They refuse to sell anything
other than passenger car LT tires, as well as refusing to service
older cars or any other vehicles *or* loose rims that could be put on
them.
