3820FK MORryde LRE/4100
Good afternoon,
I have a question about the appearance of the big block of rubber where both springs attach directly behind the label that says Morryde, has anyone else ever noticed cracking in the rubber in this area? is this normal or do I have bad rubber. Its a late 2016 Montana with only a couple thousand miles on it. Also Ive noticed a lot of people talking about the trailerking tires which ofcourse is what I have. should I definitely get these replaced ASAP and with which tires would people with 5th wheels in the same weight class recommend ? I do have 110 psi wheels. any advice would be greatly appreciated.
Thank You.

Tommy,
Some cracks are normal - depends on how bad they are.
Go with G rated tires - Sailuns offer great value but there are others that will give you good service at a higher price point.

I have your model trailer and replaced all 5 tires with Sailuns after our 1st road trip of 3K miles. I absolutely feel so much better knowing those Sailuns are on my rig and are monitored with a tire minder. The extra $1000 is well worth the piece of mind.

The has been a lot of previous discussion about the Mor-Ryde rubber blocks. Back in 2013, Dieselguy wrote an excellent post about them.
We all probably have some degree of cracking ... this is very similar to a motor mount. Here's the inspection info right off the Mor/ryde's website. As stated, delamination is another failure scenerio.
Rubber Shear Spring Inspection
The rubber springs (Fig. 3) should be periodically inspected for any tears or cracks. If a rubber spring exhibits a 3” long and ¾” deep crack or tear, the rubber spring should be replaced. This can be checked by using a flat tool such as a putty knife. The putty knife can be used to probe the rubber spring in the affected area. If the knife can be inserted ¾” deep, by at least 3” long, the spring rate of the spring is affected and should be replaced.
Note: It is normal to see rubber spring weather checking, which is small surface cracks in the rubber. Weather checking does not require a rubber spring to be replaced.

You should read all of the topic as there is good info scattered throughout. Try doing a Search on "mor rubber cracks" and you will get interesting posts and even pictures.
