16" SenDel/Michelin Combo

[56ovalwindow]

We spend most of our time away from improved sites. Trailer is “lifted” and taller wheels/tires will give us a bit more clearance when crossing creeks, streams, and shallow rivers. Trying to keep from damaging the drain pipes and valves.

16" Michelin LT225/75R16/E LTX M/S2 tire is rated 2,680 pounds @ 80 psi and 29.2" diameter

15" Michelin LTX (P) 235/75R15 XL tire is rated 2,183 pounds @ 50 psi - derated to 1,985 pounds and 28.9" diameter

15" GYM ST225/75R15D tire is rated 2,540 pounds @ 65 psi and 28.3” diameter

15" GYE ST225/75R15 tire is rated 2,830 pounds @ 80 psi and 28.3" diameter

14" GYM ST215/75R14C tire is rated 1,870 pounds @ 50 psi and 26.7" diameter

The 16" Michelins will work in any wide body twin or triple axle Airstream 25' and longer. The increase in ground clearance is 0.45" plus more proven reliability.

We upgraded the stock 14" GYM tires and wheels on our 2015 23D to the 15" Michelin tires above on 15" SenDel T03-56545T wheels rated 2,150 pounds at 60 psi that match the 16" SenDel T03-66655T wheels mounted on our Classic with the 16" Michelin tires. This elevated the 23D 1.1" to the same elevation of our 2013 25FB so the reused Hensley hitch of the 25FB worked with no modifications of settings on the 23D using the same tow vehicle.

I have heard the factory wheels are rated for 2600 pounds. I would personally want wheels rated for that load or more. The same for tires. (Depending if they had to be de-rated because they were not designed for trailer use.)

The Goodyear tires (GYM) listed above are no longer available. Replaced by Goodyear Endurance. (GYE) And the GYE seems to be a far better tire than the GYM with now some history of them in the field.

My prior post mentioned the 15" SenDel wheel with the five lug bolt pattern of the 14" stock wheel on our 23D. The center hole is the same diameter as the OEM wheel so we reused the center caps.

The 15" T03-56655SM SenDel for six lug nuts is rated 2,830 pounds at 80 psi.

The Classic's 16" SenDel T03-66655M wheel is rated 3,580 pounds @ 80 psi. The center hole can use the stock Airstream center cap.

Hi All,

Just reading this post as we are in the process of purchasing new wheels and tires for our 1988 29' Argosy.

We have ordered 2 new axles from Colin Hyde and should be here in about 2 weeks. He recommended the following for wheel/tire set up:

Michelin 225/75/16R (2800 lb each load rating) tires
SenDel 16" TO3 Wheels.

He suggested we go with the 225/75/16 over the 225/75/15 for more weight bearing.

I'm seeing posts where other Michelin tires are suggested and referenced so looking for input/thoughts on this combo.

We are heading out to full-time around end of June - house goes on the market in 1 week. Crazy busy around here with the sale and renovation at the same time.

Thanks so much for any input~

The 1988 Argosy has a GVW of 7,300 pounds, the same as our 2013 25FB International Serenity. We mounted 15” Michelin LTX [P] 235/75R15 XL passenger tires as recommended by Andy at CanAm. They are rated 2,183 pounds but must be derated to 1,985 pounds for trailer use. There is a new “Defender” series in that size with a higher load rating that puts the derated load over 2,000 pounds.

We ran 44 psi and the trailer had a softer ride and a larger foot print on the road than the stock 15” GYM tires.

We upgraded our 2015 23D International Serenity from the stock 14” tires and wheels to the 15” Michelin tire captioned above mounted on 15” SenDel T03-56545T wheels (five lugs for 10” brake drums) and they matched the 16” SenDels we mounted with the 16” Michelins on our 2014 Classic with a 10,000 pound GVW.
