Help! I can't find tires for my single-axle Ranger Trail trailer. The 17 year-old Michelin P215/75R14 tires got old, 2 years ago a problem developed with one and I replaced it with a same-size Toyo (Michelin no longer makes this size). Now, I gotta buy two more and can't find any. They're telling me there's a shortage of Toyo tires due to the earthquake disaster in Japan.
The problem is that I'm stuck with this size due to the limited fender clearance and the wheel size. And, I need the 1664 lb load capacity (each tire). I'm asking for helpful suggestions. Thanks

Do NOT go with Carlisle brand tires. They have brought me nothing but trouble.

There are many factors that effort trailer tire ware, road surface,appropriate axle size and flexability, correct tire chamber, correct load range tire, tire speed rating etc..etc... If you have a single axle trailer and a heavy boat 2,000 lbs or larger, I would recommend you look at a load Range D tire. Load range D may not be necessary for those with a tandem axle trailer other than the speed rating. The majority of ST (Steel Radial Trailer) on the market are load range C tires with a maximum speed rating of 65 MPH. I believe most of the issues I have experienced where due to Load C (4 ply) and the low speed rating of 65 MPH. I usually travel at 65 to 70 MPH when pulling my boat and most of my tire separation has occurred on long trips that exceed 65 MPH. Due to fender clearance I am limited to using 14" rims. I spent some time researching RV forum sites and discovered that these guys are having the same issues with tire separation on 14 " rims. I have tried 6 ply bias and radial tires and I believe the radial tires are best for me since radial run cooler. I have tried all brands over the years and was sold on Goodyear Marathon tires up until about 6 years ago when I started having issues with them. The RV guys are now recommending the Kuhmo 857 over the Goodyear tires. The Kuhmo 857 tires are 6 ply with a high speed rating of around 90 MPH if my memory is correct. I purchased a set about a year ago and I am very pleased with them to date--will know more in another year. When I purchased mine, these tires were hard to find. I got mine on line from Tire Rack. If you currently are using a ST 205/75/r14 tire you will need to purchase the Kuhmo in a 195 R 14 size to get the same tire size. Not sure why the difference but I assume it has to do with the load range D vs. C and 6 ply vs. 4 ply. In my search, I also found a Hankook also sells a 14 " trailer tire in a load range D. Tire details listed below for 14 inch tires:

Kuhmo 857 195R14 Load D Max Load 2094 65 psi 7.8� wide 26.2 � tall

Hankook RA08 195R14 Load D Max Load 2094 65 psi 7.6� wide 26.3 � tall

Hope this helps
I did my research and I'm going with the Kuhmo also buying from Northern tool for 19.99 a pair of tire cover so they don't get sunburn while parked outside.
