Asymmetric wear of tires
Dear all.
I need advice.
I have a fairly new Domane S6 2017.
Came with 25" tires. I called Bontrager and they told me I can fit 28" with no issues.
So I did. I also got new (larger tubes) and a bike fit.
The bike gained a lot of comfort and performance even though I know most of it has to do with the fit.
Anyways. While Im happy with the new set-up, I have done about 100 miles so far and noticed both tires are not wearing out exactly in the center. They are slightly biased towards the left. Especially the back tire. You can barely notice the front one, but on the back one there is at least 1 mm bias.
What can cause this? Was the change in tires?
I also wonder the potential issue this can have.
Previous tires: Bontrager R1 25mm
New tires: Bontrager R3 28 mm with continental sport tubes.
Any advice is greatly appreciated.
