The SenDel site wheel specifications area was operational today. See the attachment.
We used the SenDel T03-56545BM wheel on the 2015 23D International Serenity to replace the OEM 14" GYM ST215/75R14C tires rated 1,870 pounds @ 50 psi mounted on the factory stock 14" wheels.
We installed the Michelin LTX (P) 235/75R15 XL tires which are sidewall rated 2,183 pounds @ 50 psi, but must be derated to 1,985 pounds for trailer use. (See 49 CFR 571.110 for the derating details) We run 44 psi per the CanAm pressure suggestion which is the same pressure we used with this tire when I installed them on our 2013 25FB International Serenity that had a GVW of 7,300 pounds versus the 23D GVW of 6,000 pounds.
Mechanically on the 23D, we had to trim the metal on the front curb side wheel well opening to be about ¾" away from the plastic wheel well which is the opening setback from the wheel well on the street side of the trailer. The opening was 3" set back.
Our 16" Classic wheel and tire conversion used the T03-66655T wheel which is the model Airstream installed on the Eddie Bauer and installs on the 2015 and later Classic. This wheel plus the Michelin LT225/75R16/E LTX M/S2 tires are for sale at the Jackson Center customer service store as replacements for most 15" tire and wheel applications.
Note that the 14" Airstream wheel hub was used in the 15" SenDel wheel as they both had the same 3.19" center bore. The factory 15" wheel hub was used on the 16" SenDel wheel as they both had the same 4.50" center bore.
