The Marathons will have a higher load rating and are going to be better the unknown quality Freestar hecho en China ones we have now. Marathon is a better choice I've gathered from all the personal opinions I've seen. Biggest factor I see in failure is improper care, not where they are made. Too many just don't take care of their tires properly.
To throw out comments like all made in China tires are bombs waiting to happen is wrong. If that's what someone thinks, they ought to have something factual to back it up. Did the owner stay under 65 mph? Did they keep tires inflated correctly? How close are they to the GVWR or actual trailer wt? Towing on bumpy roads a lot like the washboard sections of I-5 in northern Cali? Tires balanced ever? See what I am getting at? ST tires can't take the same abuse that we're used to on automotive tires.
I've had the steel cords in 3 tires fail on tires in total while driving on the I-5 in Norcal. Two one trip and the other on a later trip. The first 2 were fairly new too. I can only imagine what that kind of road would do to ST tires. So if your ST made in China tires failed there, you'd automatically call them bombs???
I hate made in China quality just as much as anyone else these days, but you have to keep things in perspective and factual otherwise statements are meaningless. In fact, to take things a step further, then stop buying anything made in China and stop enabling them. Where are your clothes made? Kitchen plates and utensils? Electronics in your home? Just stop it already and stop whining about it. But nobody will 'cause the prices are too attractive and no-one can resist, from manufacturers to individuals. Don't get me going here!
If anyone can give me owner's experiences with Freestar tires, I'd love to hear about them. Google comes back with very little info. on them. May not have been around long enough yet to explode.
I have two choices with the dealer. Go with the Freestar load range C or upgrade to Marathon load range D. The Freestars are only 480 lbs above the GVWR which is not good. It's a no brainer as far as I am concerned without spending big bucks to upgrade from there.
Dealer is either woefully ignorant or does not want to get involved with discussing weight issues. Not a good way to run a business if you ask me.
