Tire replacement?

redaunt

We have a 2016 320, Outback edition. It still has the original tires. From 2016 to 2019 it was stored outside in Austin TX with a cover. We moved to New Mexico in May 2019 and it was stored outside (no cover) for about a year, maybe 18 months. Since then it has been stored inside. Our trips are generally short so it’s doubtful we have more than 10,000 miles on the tires. Still lots of tread on the tires. We are planning a trip to Montana in August. We took it camping last week (about 250 miles round trip) with no issues. Do we need to replace the tires before driving from New Mexico to Montana?

I'd be tempted to replace them before a long trip. "They" say every 5-6 years for replacement regardless of mileage. Here's an article:  https://camperreport.com/how-long-do-camper-trailer-tires-last/

Tires deteriorate over time regardless of mileage. It would be relatively cheap insurance to replace the tires rather than risk a blowout. I just replaced the tires on my 2018 with Goodyear Endurance tires.

I'm thinking new tires for my 2017, also.  This thread has some suggestions.

We replaced ours when small cracks were observed on the sidewall.  They lasted 5 years from the date of manufacture.  Be sure to check the link note by @pthomas745

You can increase the life of tires by covering them when storing your T@b to protect them from UV damage.  These have worked well for me and are easy to install and remove.

If they are holding pressure and there is no cracks on the sidewalls ("checking" is the proper name, caused by UV exposure and not being used), they should be fine. They are getting a little long in the tooth. Age will cause failures in the rubber, but not as fast as exposure to the sun.

On a long trip is a bad time to work out a replacement. Tire rack has trailer tires available, but I don't know if they are in-stock or if they have to order. If you have a local guy you like working with, replacing before the trip may be the better choice.

If you plan on new tires, I would recommend replacing the spare too. People forget about the third tire until they need one.
