Trailer Tires - locked up brakes

I was trailering my boat today daydreaming and had to hit the brakes a bit hard which caused my trailer surge brakes to lock up. Unfortunately now 2 of the tires have a flat spot(no tread) from sliding on the pavement. Do I need to buy new tires; are they dangerous, or should I be OK?

Post a picture or have a tire dealer look at them but sound to me like you should replace them if you tow any distance or at freeway speeds.

If you have carsile tires replace them ASAP, They are just waiting to delaminate on you at the worst possible time.

Dang, how long were you skidding in order to put a flat spot on the tires. Had to be a heck of a patch.

I was thinking about replacing the Carlisle tires anyway. I found some Good Year Marathon on Tire Rack for ~$65 each. What is the difference between B rated and C rated?

Read this article for all the info you need:

Basically the letter refers to the max towing speed the tire is rated for. The max speed for B rated tires is only 31 mph and on the C tire it is 37 mph. Most likely you need to find a tire that is rated at least a G.

Yeah drive directly down and unload those Carlisle Tires. They are prone to delamination even when the treads are good. (Happened to me & at least 6 others that I personally know) Can't go wrong with Goodyear Marathons !

What size is standard on the MC trailer? Anyone know. I wanted to take a look on the net for tires and don't have the size in front of me.

My Carlisle delamed after 3 months and less than 1000 miles. When we pulled them of at the tire place I couldn't believe how floppy the side walls were, replaced them with light commercial truck tires, hopefully they will be all good now.
