try southwest wheel they sell reasonably priced trailer tires

Just one other thought to this after reading about how important running the 50psi is...
If you have been running 40 psi for some time and decide that now its time to bump them up to 50 for a long trip be prepared for a roadside assistance...
Just FYI
I Now will keep that at 50..from new.

Anyone?

I have two old auto tires on my boat trailer from the previous owner which have both thrown tread. I need to replace them with trailer tires but the auto tire does not match up in size to any trailer tires. The tires on there now are 185/70/13. What size trailer tire is the equivalent to that? Looks like I will be buying from selecttire.com as none of the local places could help me with the 13" trailer tires. Any help is appreciated.

I have had to replace 7 Goodyear Marathon tires in the past year. I have 3 boat trailers and a travel trailer. Every one blew out sitting in the driveway and not moving. Even the spare tire on the trawvel trailer blew out. If these go bad I will never buy another Goodyear product and would suggest every one do the same. Could use suggestions on a good tire brand.

I have a Champion on a tandem axel trailer. It had Carlisle Tires and 2 blew out and 1 seperated. I now have 2 Maratons and 2 supercargo's. I will see which goes first! Now I have to repair both fenders and repaint. Thats a drag.............

I've been running regular car tires to haul my Ranger around for years. No problems, no flats. I'm running steel belted radials. Trailer tires or car tires both are succeptible to flats. Only difference I saw is that my radials tend to allow my trailer to bounce a little down the road as apposed to a stiffer ride. My Ranger doesn't seem to mind as long as I get her to the water.

Trailer tires are designed for intermittant use with long periods sitting in one place. They are designed to not develop flat spots from sitting.

Car tires if left sitting under load for long periods will get a flatspot in them, and will cause addition wear, as well as additional bouncing type stresses.

Go with trailer tires, the extra 15/20 per tire is well worth it.

IMO, Carlisles are a waste of time and money. My last set of tires I ordered from a tire company on Burnet Rd. in Austin. I ordered Marathons, but Goodyear sent the place HMG 2020's. So far, they have been good tires. They say "Property of U-Haul" on the sidewalls though, so I kept my receipt.

someone told me that goodyear trailer tires are made by carisle. don't know if this is true though?

Goodyear Marathons.

I just got two Tow Master II Radials from Plano Tire at 15th and 75 in Plano, remove and dispose of old tires, balance and mount new tires for $162. I was recommended there from someone on TFF and told to ask for the Manager Mike as he is a fisherman and on the board frequently so that is what I did. Mike was a nice guy and from the research I have done I think I made the right choice with the Tow Master II Radials. Time will tell.

Being you have 14's i would stay with a trailer tire in the recommended load range or one above it. On a load hauling trailer with a larger size 15 or 16 i might put on a LT truck tire but for your application the trailer tires would be a more safety conscious not to mention the liability is not on you if something were to happen if you are running with a manufacturer recommended rated tire. Rwegardless of what tire you are using; tire pressure on a trailer tire or any tire really is critical to the wear and to the ammount of heat it generates and dissapates which is usually the cause of separations and blowouts. Always check your pressures and balance them you can have a 10 psi difference from summer to winter here in texas. If the tire shop has a nitrogen fill station ask about it many do i would recommend having them fiilled with it as it doenst vary when things heat up. Its cheap insurance to the temp thing if you dont ever check your pressures and adjust them.

The last sentence in your post says it all. Anything with the load rating that is not "made in China".
