The Michelin LTX tire for SUV's and light trucks is a P rated tire with an XL load rating. They are rated at around 2135 lbs at 50 psi. You need to down rate the load by 10% for a trailer application. (comes out to 1985 lbs) Much different from a P tire that is only rated to 35 psi. Michelin used to offer a similar LTX tire that carried a LT C rating (50 psi). They dropped it. I am not suggesting using any other P rated tire and would not use any other P tire. But the Michelin LTX XL works fine on my trailer. Works just like the C rated LTXs I had on before. Michelin does not endorse any of their 15" tires for trailer use. I have run the LTXs for 6 years now, 5 on the LT C tires and 1 on the P..XL tires and still like them. If you are not sure you will, just get the GYM's and check them regularly, And you will know that you are using the "right" tire for trailers.

Thanks for your help.
Yes. The question was: What was the original tire size on the trailer? Overland63 thinks they were either 7.00-15's or ST225/75R15's.

But I'm not satisfied with that answer because a 7.00-15LT has a load carrying capacity of 2040# at 65 psi, while an ST225/75R15 is 2540# at 65 psi (Both Load Range D)., while an ST205/75R15 LR D's is 2150# at 65 psi.

Robert,

There are passenger cars and there are light trucks, - AND - there are Passenger car tires and LT tires - BUT - in the cross over, there is a mix. Large PC tires are used on light duty light truck vehicles - hence the description. (But it never occurs that LT tires are used on PC vehicles)

To eliminate the confusion, it is common to use the phrase "P metric" and "LT metric" when describing tire sizing. P metric tires come in "Standard Load (SL)" and Extra Load (XL)", while LT tires come in Load Ranges (C, D, E, etc.) although you will hear people say "ply", as in "6, 8, or 10 ply" (where 6 ply rating = Load Range C, 8 PR = LR D, etc.)

Those 2 types of tires are quite different - and as has been pointed out, in order to use a P type tire on a LT vehicle(which would include trailers) the load rating has to ben decreased by a factor of 1.1.

I am so sorry. Didn't read correctly.
Yes, you are correct in that they were 7.00-15's.
Thanks to everyone for their insight.
