Hey Patrick, thanks for reaching out!
I recommend picking up the Kenda K371 Bias Trailer Tire # AM10004 and using the Americana High Pressure Rubber Snap-In Valve Stem # AM20907 for your wheels. This tire has a 65 mph speed rating and can be inflated up to 90 psi which is why you'll need the high pressure valve stem.
As for the bearings, we have the # L44649, but we don't have the LM11749. To replace the seals and dust caps though I'll need you to take some measurements of the seals (inner and outer diameters) and the diameter of your hub bore where the dust caps install so I can make the correct replacement recommendations.

Hey Patrick, how did the Kenda K371 tires and high-pressure valve stems work out for your sailboat trailer? Once you measured the seals and hub bore, were you able to find the right replacements for the bearings and dust caps? Your update could make it easier for others working on similar small trailers.
