How do Schwalbe tires age?

Geof Gee <geo...@gmail.com>: Aug 06 10:41AM -0400 What rims do you have on the Crusoe? My personal experience is that Schwalbe tires are difficult to mount properly on the Alex DA16 rims that often come with Bike Fridays. (is it DA16? Can't remember off the top of my head) Bike Friday wrote some blip about it at some point.   -G Arlington, VA     --   "Sometimes I forget things. Who I am. Where I am. Unimportant things.

Ken Preston <ken...@gmail.com>: Aug 06 10:46AM -0500 The rims on my Crusoe are DM 18 rear, AX 18 front. The rear is a second wheel for this bike. The front is the original one. I've had the tire problem we've been discussing with both of these rims.   Ken   On Aug 6, 2025, at 9:42 AM, Geof Gee <geo...@gmail.com> wrote:      What rims do you have on the Crusoe?

They are at least 4 years old, low mileage (at least riding miles; we moved the bike from Utah to Nova Scotia a few years ago), and the tread is still very good. However, my wife started noticing a wobble in her front wheel, which I confirmed had nothing to do with how the tire was seated, nor any visible damage to the tire. I have removed and reinstalled the tire a few times with no change and the wobble is very visible when I spin the wheel with the tire in place. The rim is lovely and true. Yesterday I rotated the tires (front to back) and the (formerly) rear tire was also distorted, but not as badly. On our ride, my wife claimed the ride was much better than before.   Eyeballing things, I can see some side wobble in the newly installed front tire but the rear tire has side-to-side and some up-and-down wobble, which she very much notices on the front, less so on the rear. She is happy in the short term, but I am not happy with tires deforming like this.   Question: is it common for tires (Schwalbe Marathons in this case) over time to experience this sort of deformation? I cannot recall it from many previous tires, but mine tend to wear out in the tread before they get to be 4 years old.   I will simply order new tires and get on my life, but I was curious if this behavior was in any way specific to these tires, suggesting I move to a different brand (assuming I actually have options for 20 x 1.5 in (40-406) tires).   Thanks in advance!   Best,   Rob   --   another great conversation from the Bike Friday Yak!   ---   You received this message because you are subscribed to the Google Groups "Bike Friday Yak!" group.   To unsubscribe from this group and stop receiving emails from it, send an email to yak+uns...@bikefriday.com.   To view this discussion visit https://groups.google.com/a/bikefriday.com/d/msgid/yak/3526B5A2-F059-45BA-B19A-EC4B7A7FB3A6%40gmail.com.   --   "Sometimes I forget things.

All our bike are stored inside our attached garage. It is not heated so does get hot in summer and cold in winter. I live in central Canada so cold means -30 sometimes. 

Most of my riding on my Crusoe is on paved roads or paved bike paths. I would say less than 10% is on gravel or crushed lime trails. 

As I mentioned before this distortion of the tires seems to be exclusively on Schwalbe tires and the 20”, 406 size. I run Marathons on my road bike and my Brompton yet have not had the same issue unless the tire is very near the end of its useful life.
