Now I am confused about tires

[urb2165]

Now I am confused. I will need to replace the 4 tires on my 1959 Ambassador. They are 700 x 15 now.
I was considering going with 225 X 75 X 15. But now do I need D or E rated tires?
I have also been told that each wheel should be steel and rated at 2600 Lbs or better. Each wheel should be 15 in x 6in with 6 hole patter with a 5 1/2 bolt circle and zero offset.
Suggestions are welcome.

I'd buy these:

Marathon ST225/75R15 Tires

ST225/75R15 2540 lbs (D) rating (with all 4 tires will support up to 10,160 pound trailer weight.

If the wheels are Airstream factory wheels you should be ok. However, I think the wheels should have their rating placarded somewhere on the wheel.

The best scenario is to match the tire load rating with the max load of the trailer + 10%.

Too low a tire rating and the result could be very exciting situation.
Too high a tire rating and it is a waste of money and potentially a harsh ride for the trailer.

So "D" or "E" rating sugestion becomes a guess not knowing what your trailer weighs when fully loaded with gear and liquids. Or one needs to know what the GVWR, however a 1959 unit did not have that kind of rating when it was manufactured.

We recently replaced the tires and wheels on our "78" Ambassador. The specs you listed are correct for our Ambassador...I assume they may be the same for yours. Purchased our from: 15" SIX BOLT ALUMINUM TRAILER WHEELS FOR TOWABLE RV'S, FIFTH WHEEL TRAVEL TRAILERS, BOAT TRAILERS, CARGO TRAILERS, HORSE TRAILERS AND MORE Great people to deal with and fairly priced.

Going sideways here....have you had a chance to check out those new wheel balancers called Centramatic wheel balancers -- you can see a demo on you tube. They are made in Dallas and theirs cost around 200.00 for a set. But the company that makes them says that Inland RV is cheaper. But they are a cool finishing touch to your new tires if and when you get them.

Here's that link....Centramatic Happy reading!

It seems I my be in the same boat soon, having to replace my tires. Another question is can you replace them with truck tires. it seems most trailer tires are only rated to 65 mph. would I or someone else be better off with a D or E rated truck tire that is built for higher speeds. I have noticed my tires can get warm in the summer at highway speeds and my the tires on the TV are not as warm...

I recommend checking this link regarding special trailer tires, light truck tires and passanger tires.
