7.00x15 6 ply Load Range D
I need to replace the tires on my 1967 Trade Wind. the current tires on it are badly weathered. The tires on the wheels (which are original) are 7.00x15 6 ply load range D. I thought 6 ply were always load range C. I'm thinking of getting the Marathon 225/75/15 tire, load range C, as I am concerned about the warnings regarding splitting the rims if I were to upgrade the tire. I'm just confused about the tires on there now.
Thanks,
Wayne

These tires are still available--The sidewalls are stiff and they hold 65 pounds of air. Radials flex more than these bias ply tires. I replaced mine with the goodyear 700x15 6 ply @ $87. each. They ride and track beautifully.

Boy am I glad that this came up. We are going to replace the tires on out 54 Cruiser and replace the split rims (cause they REALLY are split) and was wondering what size rim would I need to get for this tire?

I have tandem axles. What tire are you using, and what size?

My old tires are Kelly Springfield Custom Armor Trac. They are rated at 2040 pounds at 60 psi. They are bias ply. What model Goodyear tire do you have? Are they radials?

Rasmuw,
There are very few reasons to buy bias ply tires today. Number one to me would be an original restoration. Number two would be a sidewall penetration if you go off road a lot. Number three would be to get an exact same size tire.
Radials run cooler with less rolling resistance, turn nails much better but, the 225/75r15 is about 1/2 inch lower at the axle centerline which can cause the rear to drag.
You could buy load range c or d and just not inflate the lrd above 55psi.

I just checked last night and I have 7.00-15 LT's on my trailer. Dual axles. Now I am a little worried that the LT's should be replaced for ST's.
When I got them I specifically asked for trailer tires.
I will say that the tires look in great shape and have given us zero problems (save having to add air on occation).

Im not a big fan of radials on a trailer at all. Ive seen what they do to one when they blow out. They dont just go flat like a bias ply tire does. They come apart in a big way!! I have seen my friends A/S damaged from radial blow outs.. Im thinking about putting bias on my 1997 30 ft Limited..

You want TRAILER tires The stronger sidewalls keep the sway down. The height is correct and since no tire on a trailer is good for more than 5 years, I plan on running these on my 73 tradewind forever.

Bias-ply runs hotter and doesn't last as long as radials. They were superceded in design more than forty years ago, and haven't been oem provided on cars in more than thirty years.
LT tires are, according to dealer Andy Thompson, more resistant to punctures than the ST tires. I have had both bias and radials on my trailer and it was obvious that the bias-ply tires were having to work harder to do the same job; I went to LT tires of the same rating (both at the recommended weight-rating for the trailer; "ply" rating is obsolete) and now have tires that:
are used in commercial service on delivery trucks that see constant, changing loads and abuse, yet stand up well
run cooler, with a better tread design
are unlikely to be worn out at the end of five years
are tires that the manufacturer depends upon to make and ensure their reputation among commercial customers
The ONLY bias ply tires I now see as being sold new are on ridiculously small trailers sold for homeowners to haul, maybe, an ATV or a lawnmower or two.
Twenty years ago this argument may have had some validity.
Heat is what weakens and kills tires.

Blow outs...
Hello Airboss,
I am also concerned about what radials do when there is a blow out....or should I say blow up! I have seen a number of AS damaged because of this. I have a 25FB and am thinking of swapping my marathons out for bias. Which bias would you recommend?
Thanks, Randy

Those Carlisles are the ones I removed. And, it isn't true that they don't blow out. But you're welcome to them, and good luck. Let us know what you find after a few years of use.
