After 8,000 miles, more as these miles were from the last two trips, with the LT225/75R16 Michelins... I could have easily gone to LT235's. The LT225's have been a no issue and the extra bit of extra rubber on the road may, in the long run, be just as good and offer just a bit more traction.
I have not priced the small extra width as a comparison. If I was concerned about costs... I would have bought some fiber glass trailer with some brand of tires that I have never heard the brand.
There is a lot of space between the LT225's and the outside fender skirting. The 16 inch wheels and tires leave a lot of room... as I have a three inch lift, also. Without the lift, to change a tire you may have to get the trailer a couple inches higher to make handling the wheel and slip out to replace with the spare. I discovered that on the 25 Foot Safari. It was a NON issue, but never had the need to change the tire. This I discovered when replacing the 15 inch Goodyears with the 16 inch Michelins.
If I stand behind the trailer, the LT225's look narrow in the fender well. When inquiring about the LT225 and LT235 choices... I received NO RESPONSE. I became 'spooked' without having any experience from others of the minor width change.
Now... IF and it could never occur I purchase replacement Michelin tires for our current 27 foot International... LT235. Off the Grid Boondocking roads have not negatively affected handling or the tires. We carry a full Fresh Water tank, empty Black and Grey, full pantry, hardware... when traveling.
I will try to get the new 30 foot Airstream Michelin LT tire widths next time we are at the local Airstream dealership.
When you 'upsize' to 16 inch tires and wheels, the 15 inch Goodyears are in demand for boat and utility trailer owners. The five wheels and tires sell quickly on Craigslist at 75% to 80% of Costco kind of pricing. I would price the best price you can find and ask 80% with room to negotiate. These guys pay in cash... no checks... no problems.
The hustlers say they "only want the tires" as they have the steel rims. Probably rusted up and look trashy parked in their driveway. Don't fall for that line, but expect it and make them pay up.
I have not heard from anyone personally who has had ANY issues with Michelin 16 inch tires. Myself... we go to places most Airstream owners would never find appealing, which is Off the Grid and I am putting a lot of confidence in these tires to get us IN and OUT of our remote campsites.
Michelin tires are easy to find if ever... needed. I have a wonderful Trailer. If the trailer could dance... I would find the best shoes that fit and be happy for years.
As I always say. I am not a Michelin Dealer, Salesman or Tire Expert. I do not own a 'tire stock'. My opinions are from USE. Soft rubber. Hard rubber. Lots of mumbo jumbo out there.
My 2016 F350 diesel 4x4 came from Ford with Michelins. The high end longer Airstreams come stock and listed on the side tire guide as stock tires.
