Tire size and axle

I have just purchased a 1960 Tradewind. She was just sitting in the owners backyard for the past 15 years. The tires are flat and need replacing. Can I use the newer style tire size instead of the original 700x15 with out sacrificing safety and the possibility of the tire rubbing? The axel is the old style leaf spring. Do I need to replace it with the newer style or stick with the leaf spring one?
Thanks,
Terry

Welcome to the FORUMS !!

Hello, This response it just my own personal opinion; Using the axle as is will be fine. You should check all mounting bolts and make sure there are no broken spring (leafs). Be sure to check the brakes and repack the bearings. I prefer to use the bias ply 7.00 x 15 tires. They are more readily available in most areas, lower in cost, give the trailer it's original ride height, and the tire is stiffer in the sidewall. Stiffer, makes for less sway, especially for the single axle trailer.

I'v only seen a few of the leaf spring models, don't recall if you have shocks. My one recomendation is to replace or add shocks for a leaf spring trailer. We're told we don't need them on the torsion axle models, but it seems we all maintain them, anyway.

I think you should replace it with a new torsion style axle.

The original tire is 7.4" wide. If you replace it with a new metric ST tire the width is 8.8". I think you will have problems with the shock rubbing against the tire.

I own a 60 trdwnd and have the original hadco axle in it .I put in new brake
assemblies and replaced the springs (for my own satisfaction ) Sugarfoot
here on the forums also has a 60 trdwnd and just had her springs rearched .
Same tough hadco axle .no need to go with a torsion axle for any reason
that I can see if you have the original leaf spring unit in there .The hadco
axle is plenty strong .I run 700-15 Bias 9 ply tires .they look great due to
the heavy ribbed edges as original and they have a stiffer sidewall for better
stability ,the radials are softer ,ride smoother for sure ,but they cannot compare to the side wall strength of the bias .Mine have 4 plys in the side wall and 5 plys in the tread .All st tires have only 2 ply sidewalls .
most all bias tires will fit without rubbing the shocks ,fit the wheel well fine.
goodyear makes the workhorse rib ,towmaster offers bias (ive used them )
and I run herculese Bias now with great results .You do want new steel
2600# wheels with new tires (no split rims) all easily available .The shocks can be removed and matched up at your local napa or carquest stores .
they can go to the book with the specs of your old shocks and get you new ones .Alot of 60 trdwnd owners on the forums with the original hadco axles
in there trailers .The 59 units had smaller axles and smaller wheels and tires ,
so I also would upgrade to the 60 specs utilizing the heavier axle.The torsion
axle does offer a smoother ride so it is an alternative if you want to change out your whole axle .It does require axle mounting plates to be welded to your frame and alignment of the new axle to track straight plus shock relocation as well ,although the popular idea is too leave the shocks off the torsion axle but Airstream did not feel the same way and had installed them on all torsion axles up to present day ,now it appears some units today may or may not have shocks .they do serve a useful purpose to control tire rebound and do increase wheel control ,thats the point of having them .
Anyway ,for now just install the new wheels and tires and get her home
and decide what you might want to do .welcome to another 60 tradewind
owner .check with flyfshr here also ,hes got a registry going .what is the
bath configuration (ohio or ca built ) and the serial # .

I agree with Scott, there is no reason to try to re-engineer your suspension. Leaf suspension is fine, and if you decide to replace the axle and springs in-kind, total cost would be around $400.
Also, you can find 7.00Rx15 load range D tires for your trailer, they will give you the benefit of the radials, without losing ride height, or causing clearance problems in the wheelwells.

And I agree with Scott and Terry. Yes, I had my springs re-arched and an extra leaf added last week. Gained 2" clearance which I needed because of new sewer fittings. The spring shop said the old Hadco axle and existing springs were in great shape, would be a waste of money to replace right now. The original setup for the 1960 TWs are less expensive to repair and have stood the test of time. First, get it home, check it out, then decide what works for you.

As far as a newer tire rubbing the shock because of increased cross-section width, this can happen. So measure carefully for clearance if you upgrade. A D class tire would give you more safety margin handling load. Congratulations to another 1960 Tradewind owner!

Serial Number

The serial number to my Tradewind is 240261T. What does that number mean?
Thanks,

Hi Terry:

Congratulations on your 1960 Tradewind. Its serial number means:

24 = length in feet
0 = last digit of 1960 model year
261 = production sequence number
T = twin bed floor plan

Best regards, and Happy New Year!

Thanks,

The Safari models had a more open floorplan, so the bathroom area would seem larger.
Terry.
No, not that Terry, the other one...

Does anyone use Goodyear 8.75R16.5LT E tires? I am considering them for my single axle Tradewind and would appreciate any comments.
