Tire Pressure

[Tomfoolery]

That's a max pressure (32 psi) for bead seating, where they snap into place rather violently sometimes. Once set, you can air them up to the rated pressure, which should be on the same line as the 'max capacity' statement, either 2150 lb at 50 psi, or 2540 lb at 65 psi, depending on ply rating. If it's a single-axle trailer carrying the , you'll probably need all the capacity those tires have to offer.

Edit: Oops, too slow.

And it says "Never mix radial and non-radial tires."

Wouldn't you have to melt them down to do that?

Ill feel better when we hear from Matt who has been trailering for 2000 miles at 60% of correct pressure...

[mastreb]

Yeah so I've just gone 3000 miles at 32 PSI. Lot of wear on both the inside and edges as you would expect--down to nearly smooth on those edges, but fine in the middle. Now that I'm on the proper PSI the boat is a bit bouncier and fuel economy has gone from 15.8 to 17.1. I've got a spare, a jack, and a breaker bar with me, and I think that preparation has kept me from getting a flat, although with the corrosion on my lug nuts I doubt I'll be able to get a wheel off on the side of the road.

In any case, I'm going to keep riding on these until they give out or I get back to San Diego, having a new spare, the boatus trailer tow insurance, AAA, and Benz towing lined up along with a flexible schedule.

Being of an engineering mindset of course I like to test to destruction.

I have to give these Carlyles props for not blowing thus far.

Hubs are keeping cool. I'm certain they're over greased at this point so I'm going to leave them alone for a while.

I'd be juicing a little penetrating oil on those corroded items anytime soon - just in case....

I'm hoping nothing happens, but there are a lot of places out there that you just don't want to have a flat at. No place to pull off or an area you might not want to pull off and sit in with your family. We have AAA also, but there are a lot of places I wouldn't want to sit waiting on them to come. We waited over an hour in AZ a year ago when the radiator on the Suburban blew out. Having a blowout or even a gradual flat can just be a dangerous situation in itself.

Our tires were wearing on our Canada trip with the single axle. I'm about 90% sure they would of made it home, but stopped and put on new ones just the same. If they have wore like you have said on the trip I'd put some new ones on. Even if they wear that is a small cost to pay vs. the alternatives. The best,

Anyone have 2 spare tire carriers mounted on a single axle trailer for a "worst case senario" on long trips? Also, two of them might be arranged to help center the boat as it goes on the trailer with proper fendering.

I'm in the process of fabbing a 2-tire carrier right now, but the PO added a second axle to mine (before I owned it, of course ). There are many single-tire carriers out there that could be bolted back to back, using just one set of bolts, to carry two spares.

[Catigale]

That extra 80# of weight of another spare is not trivial on the single axle trailer - especially since it tends to be mounted up front at the tongue.

Still, for a X-country trip like Matt, I think I would want two tires.

Matt - if you want to order up another one and use my place for delivery let me know, Ill PM the address in case you dont have.

If you are at proper TP now, dont worry about blowout - Ill post a link to one I trailered on for 4 hours so you will feel better about your wear..



In August 2009, I trailered back from Cuttyhunk (200 miles one way) on 7 year old original trailer tires, and arrived home to find this..

[Sumner]

Cat I wonder if you would of made another 20 miles on that tire. We were at proper pressure but with the bent axle and negative camber we were wearing our tires out and fairly quickly. It is nice to have spares and the means to change them, but my main concern now is that the highways are so crowded and the places to get off on a wide shoulder are not always available and/or especially safe. It is no fun sitting right next to busy lanes on traffic that are going by at over 70 mph. When I'm towing, especially through cities I often think...'man I hope we don't have a problem here'.

Flats can happen anywhere, but a flat due to tire age or condition is one we can control,

It must have been close. The real danger was probably the fact that the outboard wheel bearing race was missing, as well as the nut, and only brake shoe friction was holding the wheel on

The replacement tires are now 5 years old, and I doubt I will run them another season. Single Axle Mac tires are just so close to the load limit I think it makes sense to eat 40 USD per year and not have to deal with flats.

Very good decision . I loaned out my car hauler trailer a couple years ago with tires a little over 5 years old but no real tread wear and the guy had two of the tires come apart down in AZ on the trip. I then replace the others, but soon I'll have to replace them again and I hardly have any miles on the trailer. My street rod has been sitting for 3 years now and I'll replace all the tires on it before using it as they are now over 5 years old.

If one is making local trips of a few miles between the house and a lake taking a chance isn't a big one, but if you hit the road and start putting some miles and heat in tires over 5 years old there is a good chance they will fail. I had that happen also to a pickup I'd drive in Wyoming short distances. Moving down to Utah at about the 500 mile mark I had 3 tires give out in less than 100 miles ,

I figure that with the second axle and a spare that I have three spares for a worst case scenario. I would hope I could repair/replace the first failed tire before going thru two more.

[Catigale]

Now you are talking Al

How about mounting the two spares angled so they turn into hull rollers for the trailer.

Come up with that elusive third function and its a mod!
