These are not
the cheap "china bombs" you read about being installed on trailers by any means.
I recommend you add steel valve stems, to get rid of the junk valve extensions, and a TPMS. FR does not
order the chassis with the M-B OEM TPMS installed. With good care these tires will "Age Out not
Wear Out" for most folks as the tires should be replaced ever4-5 years even if there is tread remaining.
The DuallyValve kit I used, and is often recommended here, can be found at Your Tire Shop Supply Here
. Give them a call and they can advise you on the correct kit. I added the front stems, with a 15 degree bend for the TPMS sensor, to my kit. They are great folks to work with... Installation, and re-balancing was $15 a wheel at a local truck tire shop so figure around $200 for this upgrade.
I went with the TST 507 TPMS...there are a lot of reviews on the forum if you do a "search" on them. I bought mine through Great RV Products
which is another good company to deal with...
