Tires, one more time!

[azfiredog300]

Hey all, hate to keep beating this subject but I'm going to get new tires on Wednesday and I want to be sure. I am a little confused too because My tires are 700x15lt, load class C but the ply rating says 4 ply nylon cord. I was under the impression that load class C was 6 ply. I have seen the threads regarding tires and whether or not to upgrade in load class. Which tires should I get and not worry about slitting the rims? I think the ones on it are at least 20years old and have been sitting for at lest the last 14 years.

If you were at Airstream or many of it's dealers, they would install Goodyear Marathon ST 225 75 R 15 Load range "C" tires on your Airstream.

You should have the dealer balance the running gear at the same time.

Also, if the trailer has been parked for 14 years, the axles are more than likely shot.

You can check them out yourself, by reading the following article.

Are you referring to actual plys or ply rating?

Stick with the "C" rating. And make sure the actual weight rating of the tires (the new ones will have this stamped in the side wall) in pounds exceeds the total load.

So knowing the total load or weight of the trailer is usefull. Towed weight would include the trailer with fluids and gear inside rolled across a scale. This data would help you when you replace the tires and axle(s) if and when that occurs.
