What tires for a Tow Dolly?

I bought a used American Car Dolly this summer that had brand new tires. After a trip to Yellowstone (from Denver) and a few local runs, the outside of the tires are completely bald. A neighbor said they were running too hot.

They are a 175/65/R14. I'm trying to figure out what type of tire I need that will hold up better. I think there are different ply's, weight and heat ratings but know nothing about tires.

Help me figure out what i need to buy, please.

THANKS!!

You have an alignment problem. The dolly needs to be aligned. We have a KK-460 and the owners manual has instructions. Do you have a manual?

No manual and no online documentation. I called the manufacturer who sounds like a one man show. He's in Minnesota on vacation for a week or so and of little help.

While waiting to hear from American, I'd load the car on the dolly and get it weighed. I agree with Mr._D, you need an alignment. With the weight information, any decent Tire store can tell you a good tire for weight and speed rating.

Where do you recommend getting dolly aligned. I started the summer with a brand new Master tow. For the first 3,000 miles the tires wore fine. Then I had the wheel bearings replaced. (Don't think they needed to be but that is a subject for a different string). Afterwards I noticed that both tires started cupping on both the inside and outside. They now have 6,200 miles on them. I'm wondering if what ever alignment adjustment are possible on a dolly may have been screwed up when the wheel bearings were replaced. Some tire places claim there is no adjustment. I had always thought that there was some adjusment possible. But want a reputable place that knows what they are doing. Don't mind replacing tires but would like to get problem corrected first.

Bad bearings can be heard or tested by jacking the axle and try to push/pull on top of the tire. If there is movement the bearings need attention. Try towing the dolly empty and have someone follow along and observe. Bouncing means tire balance, lots of wandering is a sign of out of alignment. You might also use these illustrations to get a handle on tire wear and what it indicates: Image Search Results for tire irregular wear

That tire sounds a little small for a tow dolly
My Master Tow dolly has ST205/75R 14
The S speed rating around 65MPH T means a trailer only tire,
They also have a R or a D tire...Radial or Bias ply.
Both are rated for 1760 lbs.
Some say a LT or Light Truck tire is also a good choice.

What tire pressure were you running?

Just replaced my tires on my Master Tow after 20,000 miles. Found that if I raised tire pressure to 55 instead of 50 it helped with the outer edge wearing. Replaced tires with Carlise Sport Trail ST 205/75D14. Same as came on dolly. Had bias ply and replaced with bias ply.

Tires are rated at 50 lbs. I have been running them at 45-46.
I'm glad to hear that 20,000 miles is achievable.

If I had car tires that only lasted 20,000 miles I would not be happy.
On the other hand I have paid 500 dollars for two motorcycle tires that are shot in less than 6000 miles.

Outer shoulder edges of a tire would indicate that the tire is low on pressure. check your tire pressure against the load.

If the outer edge is wearing and the inner edge is not, it is an alignment issue...too much camber.

Tires had some tread left on them, but I didn't find out about raising tire pressure until after I wore the outer edges down quite a bit. Decided it was best to replace them before I had any problems. These are also bias ply trailer tires built with stronger sidewalks. They are on a tow dolly with no suspension. I don' t think they are designed for maximum tread life.
