The tires are getting pretty old - I'd replace them.
If your trailer really weighs 4400 lbs loaded, the load range C tires are fine - you'd be several hundred lbs below their rated capacity after taking off the tongue weight. The load range D won't hurt if you're not certain about the weight though. In either case, radials pull nicer than non-radials.
Thank u all for the help, yes I think I will replace them with the D rating. found them on line for 62.00 per tire with free shipping. well worth the piece of mind.... will have the bearing greassed and changed at the same time.
thanks again for the answers
