Re: Need some tire/rim education please In reply to
Since we are in the topic of trailer tires - what is the proper pressure to put in them. I don?t have either of my trailers nearby so unfortunately I can?t speak with exact specs. I do recall on our speedboat the tires could take up to like 60lbs or more and the tires on the trailer if the 14? Lund trailer would take a similar amount. With my vehicles it is easy to know what to put in the tires but on the trailers, at least the Lund trailer, there is no sticker with recommended tire pressures. There may be stickers in the Yamaha speed boat trailer and maybe on the jet ski trailer as well.

I know that when I put all boats into winter storage I up the pressure to try and prevent flat spotting and since I can?t get to this trailers, put in extra to compensate for the slow leakage that tends to occur.

Thanks

Mark,
I go by the max pressure rating listed on the sidewall of the tire. I try to keep it at or near max.

Okay. I haven't been back on the computer much since Friday but if I can't find LT tires that would fit my rims, is there something I should look for when changing rims? Or something I should stay away from? Meaning, can I go up in tire size a little? or would that potentially be a problem since it's a dual axle and presumably that would make the tires closer together if I go up in tire size?

How much playing around with specs is okay?

I had to go up in tire size a bit, but I also needed slightly wider wheel, but only like a 1/2 inch in diameter increase for the tire. The ST tires are nearly always a unique size (my guess is to make this exact process harder). Online there are tire size converters that convert the width and and side ratio to diameter and width. There are 80 million tire sizes out there and if you can find a tire size chart that lists the sizes in order, you can go from your size and just keep going up a size step by step and looking on tirerack.com (or similar). You want to closely match size, but look at capacity and pick a tire with at least what you have/need.

Playing with the sizes, you need to not create clearance issues, so look at the trailer and see the clearance you have to work with knowing that the axles need to move up into the wheel wells.

This calculator should get you on your way:

Damn, I hate to pile it on, but wheels can also be offset (they are usually O" offset on campers). If they are offset from the factory (projected out) and you buy new zero offset rims, there can be clearance issues. I went from a zero offset to a wider zero offset.

Dani,

As Tod says, there can be a lot to understand and absorb when making a complete switch with tires and rims. It might be good if you can hit a local tire shop in their non-busy time of day and just ask for an education and some advice. I'm telling you this, not because of your gender, simply because it's a good place to learn. Now remember, I come from a small town and are used to small town friendliness. A larger town and run em in and run em out business mentality, may not be as helpful.

Mark,

My boat trailer tires call for 65lbs psi. They are Carlisle Sport Trail LH Bias - 4.80 x 12" LRC/6 ply.
My 28' travel trailer has ST205/75 R14 6 ply and I run 45lbs psi in them

Dani,

Todd has you going in the right direction. Since it's a hand me down 24' travel trailer I would suggest pulling it to a RV dealer or RV repair shop and have the tires, axles, bushings, electrical components and brakes inspected. Do you have an equalizer hitch? What ever your driving now it most likely wont match up to Steve's trucks hitch height. The hitch needs to be adjusted properly. If your still driving that Toyota FJ it most likely won't have a 7 prong plug or a brake controller. The 7 prong gives you electricity for braking and charging a onboard 12v battery in the camper. You'll have to have those installed. I know you didn't ask for any of this and maybe you already know this but it's something to think about before you get out on the highway.

Take care,

Dave,

I ask questions here in a large part because of my gender. I have been around here long enough that I do not feel as though people here would deliberately lead me down dangerous paths. I know that here I can at least get a basic understanding of almost anything so that when I go to talk to someone in person, I am not completely uninformed about what I am asking. And the folk here will be honest with me...if what I ask is stupid, reckless, off the wall...people will tell me and often follow up with WHY I need to rethink what I am thinking.

Being a woman can bring great perks and leniencies when it comes to some things. Sometimes the attitudes are very much of a bless your little heart, you are too simple to understand nature. Sometimes folk genuinely want to teach me. Sometimes they see me as an easy mark. Unfortunately I have been on the receiving end far too many times when it comes to vehicle maintenance or fixes of not understanding what is being talked about. And mechanics, some that come highly recommended, have often tried to take advantage. Sadly, I have been burned too often by mechanics that unless my vehicle is obviously in its death throes, I will no longer have anything done until I have two other people vet the information I have been given. One another mechanic and one my dad or brother or uncle.

So, I am not offended at all with what you suggest and it is something that I had already thought of. Asking questions here at least gives me a basic starting point. So hopefully when I do talk to the local folk, they are less inclined to take advantage of me.

Ed,

I have considered that the brakes may need checking out, though do breaks go bad from just sitting? That is an honest question. I do not think they would but I do not know for sure. I do still have the FJ but it will not be used to tow this trailer, except perhaps to move it around my property. I bought Steves truck so I have an adequate towing vehicle for this trailer electricity wise and hauling power/ stopping power wise. The hitch may or may not need some vertical adjusting since the truck was set up for the big trailer. It is something I will have checked out before my first big trip and something I had not considered. I appreciate the thoughts.

I get it on the mechanic thing, I hate it when they try to pull it on me and I know it is worse for women. The Toyota dealer that we go to is amazing how bad they upservice women. Standing in line and listening they get the full treatment recommended every time.

Brakes and bearings need looked at. Both are done at the same time. Bearings are an every year thing for most (manufacturer says 15K service interval on mine). If you haven't repacked bearings, it is easy and not too time consuming. Looking at the brakes is easy and you may have to adjust them (easy but weird). One of the main reasons to pack bearings and check brakes is to make sure you don't have an inner seal leak that lets the bearing grease get into the brake guts. Brakes may be self adjusting, which means they just need checked or traditional, which means they need adjusted.

Adjusting the hitch is straightforward, but often needs some seriously large wrenches that aren't commonly had. Is it a weight distributing hitch (does it have bars that need loaded with hitched up?)?

Happy to walk you through any of it you haven't done, it is all easy and takes part of a day.

I HATE going to dealerships. I do it rarely and when I do, I always leave there reminded of why I HATE dealerships so much. They seem to be the worst of the worst when it comes to trying to take advantage of people, women especially.

Are there some videos that you might suggest when looking at brakes on what to look for, or even to tell what kind of brakes I have?

Bearings are easy to do. I have done that numerous times. The biggest challenge has often been finding the right bearings to replace old ones with.

Thinking about the hitch I will have to check it out again. The big trailer was a weight distributing hitch that could definitely be adjusted. But that hitch is staying with the big trailer for when it is sold to someone else. Steve always switched out the hitches when changing trailers (camping/boat) so I gotta check to be sure. I know he left the hitch with the trailer when we put it up back at my house and if it is a weight distributing hitch, it makes sense that he would have left it with the trailer so we knew where it was. I will check that this evening.

There are not many manufacturers of rv running gear. Dexter is the largest. For the brakes, you need to check for grease intrusion from the bearings and brake lining thickness, there isn't much else, just that it moves and it gets adjusted if needed. Are the manuals with the trailer? If you pulled the drum, you can easily match the drum with the drums on etrailer.com or call the trailer manufacturer.

Usually the bearings can just be inspected and repacked, you just need new inner seals (which if you know make and model is easy to get).

Okay. I do have a weight distributing hitch with this trailer. I know Steve has used it with this truck but I do not know if it was properly set up for this height truck. He bought the trailer when he had his old one ton and I assume he had the hitch set for that truck. But I honestly have no clue.

I have a few places to look to see if I have the manuals for the trailer. Some in the trailer...others might be somewhere in storage in Cocoa. If that is the case then I will likely be better off trying to google what I have. But I shall check all the hidey holes of the trailer to see if Steve left the manuals in the trailer.

Let me know what you have for a hitch I have a common one ao there is a chance (Reese Dual Cam) and can help set it up or point you to the correct info.

I'm happy to get you started on all this if you want over the phone or via text, I'm starting to think about camper stuff/repairs for this summer already, so it is on my mind.

I wanted to give an update and thank everyone for their help.

I went ahead and just replaced the tires with new ones (Goodyear Endurance I believe....the highest ply ratings I could find). The rim that was donated to my yard actually fits the trailer so I didn't have to buy a new spare rim!

I was looking into trying to find LT tires that would fit my rims, or finding something that could be substituted but I really didn't have enough time to try and figure out what I was looking for. I had been hoping to have everything ready for turkey season.

I wasn't able to get the time off to use my permit the way I had hoped and once they enacted the curfew here, my regular stomping grounds were now too far away so I figured it was better to just stick closer to home and learn the woods here. I do still need to check the brakes and I know I need to redo the bearings. I didn't end up doing them when I had the tires off because I didn't think about it until it was too late and I was also short on time that weekend (I wanted to take advantage of a tire sale that was going on). I had hoped to be able to make one trip to the tire shop with all the wheels but turns out I didn't have enough jacks to be able to take all of the wheels off at the same time so I had to make multiple trips to the tire shop.

So, I will take a weekend in the near future and redo the bearings and checking out the brakes to make sure that they are okay.

I wanted to say thanks for the help!

Dani,

Goodyear Endurance are what came on my trailer and so far, with 12-13k miles are performing just fine. After this thread debuted I did a little digging and found out that these Goodyear tires are now made in the US. Goodyear seems to have put a lot of engineering effort into them - certainly trying to get their reputation back after the Marathon (China bomb) debacle.

Glad to hear some good stuff about the Goodyear Endurance. I was a little leery about getting Goodyear after remembering about so many issues in the past. But it was the highest ply rating I could find in town.
