All would work but I would recommend no. 1, or no. 2 if your Frontier weighs less than 5000lbs. Then I would buy new base plate mountings for your truck. If you're still unsure and have a Camping World or similar supplier nearby, perhaps you should visit them and explain what you think you need and have them make their recommendations. You can still find used on CL or eBay if you want.
I follow these tire posts with great interest. Guess I have entirely too much time on my hands and I feel the urge to comment on some of your posts, so I will. Some may notice I always use "anecdotal" to express myself WRT tires, since neither I nor others can state too many facts when it comes to tires. And we all know that anecdotal means, for these purposes, "based on personal observation, case study reports, or random investigations rather than systematic scientific evaluation," right? Also, perhaps the "urban legend" comment from one poster comes from the anecdotal evidence posted over several years. Let me also state that I don't think it's "acceptable" to have to buy ST tires every three-four years, but it seems necessary.
Good for JIMNLIN who came up with the Carlisle info that I could not find but vaguely remembered: "Carlisle website on page 93 under Trailer Tires: Tips & Best Practices; (in part), Time and the elements weaken a trailer tire.
– 3 to 5 years is the average life expectancy of a trailer tire, regardless of mileage.
– It is estimated that in approximately three years, roughly one-third of a tire's strength is gone
– After three years, depending upon storage and conditions of usage, consider replacing trailer tires even if they have tread depth remaining.
– After five years, trailer tires should be replaced in all cases." Let me add that Carlisle gets my appreciation for being stating the apparent truth about ST tires, so the foregoing is factual rather than anecdotal.
I don't have a bone to pick with China; it's just that Chinese tires have flooded the American market and it's very difficult to buy American-made tires so most of the complaints are about Chinese tires.
So, most ST tires, anecdotally, should last at least three years. One of mine recently tread separated at four years and aired down slowly; guess that's still called a blowout. Tread looked great, aired properly, not driven above 65mph (per warning on tire), etc. I used to have a Class A with Michelins. Guess what, I had one blow at six years. Why? Same thing as ST tires, except (anecdotally) Class A tires usually last about six years before suffering the same fate.
So, to everyone that says their tires lasted more than three years or six years or ten years, goody for you and I'm happy for you! Anecdotally, however, it appears you are the exception rather than the norm.
I can't say with any authority that your tires are wearing poorly from lack of balancing. However, just yesterday I saw a cargo trailer traveling down the road with one of four wheels bouncing up and down, presumably from lack of balancing. I've never figured out why auto and truck wheels "have" to be balanced in order to eliminate tire and ride problems, but some folks believe trailer tires "never" need to be balanced. The tire dealer from whom I just bought my new FW tires just quoted me a price for the tires, mounted and balanced, out the door; he gets it and I believe it's necessary, too.
.........As hard as it is to do, RV tires should be replaced after five years, no matter where they were manufactured.
Nay, nay, sez me. ST tires may last three years. See my recent post entitled "Tires and Bugs." If you can get five years out of them you are fortunate indeed.
If you want to keep your short bed PU then you need to get an automatic slider unless you want to try to remember to slide a manual hitch if you get into a tight situation. I have the SuperGlide for my 5-1/2' short bed but it's very heavy (to remove/install) and more expensive than a non-sliding hitch. As others have said, you need to evaluate what your intended FW usage will be and purchase accordingly.
I've even done that with my very heavy SuperGlide hitch, about 250lbs. My rationale was that my 210lbs. and my wife's ***lbs. of weight is more than 250lbs. and is centered directly above my hitch pin when in bed, so the SuperGlide puts less stress on the rig. At least that's my rationale and I'm sticking to it.
quote - - " I had done a visual inspection and the tires had lots of tread. Now,"
In my eyes , that was your first mistake.... never run tires that sit prolonged periods without checking the air pressure . . I check mine before every trip...
Forgot to say that I did check the pressure; all were about 10lbs low and I aired them up to the max 65psi for those tires. Of course, it didn't make any difference because of the tire age.
Haven't posted for a long time and the FW wasn't used for a year and a half. Packed it up real quick for a short trip and blew out a tire within 30 miles. I had done a visual inspection and the tires had lots of tread. Now, having been vocal about ST tires being good for three years and questionable for the next two years then definitely needing to be changed out, I know better than to run on four year old tires. It took me more time to unwrap the separated tread off the axle than to change the tire itself, and fortunately a close by tire dealer had my size in stock. Of course, I didn't have the opportunity to shop around and try to find Maxxis and settled for four new Chinese tires, again. So anecdotally, I stand by my previous statements that ST tires are going to fail after three years regardless of their appearance, yada yada.
While the FW sat for a year and a half it became infested with palmetto bugs and biting ants. Didn't notice that until we were ready to go to bed and found the ants in our sheets, and saw scurrying bugs when we turned on the lights. Yuck; we had to do a quick shake out and spray before going to bed. Got back from our "short" trip and currently doing a complete clean, inspect, and bug bombing.
