Looks like the chainring needs to move ‘out’ or ‘away’ from the frame just a little bit.
Here’s what I did to fix the same issue about a week ago.
1. Remove the crankset
2. Unscrew the bearing cone that holds the chainring against the crank
3. Put a thin washer/spacer over the crank first, then reinstall the cone ring. This will move the chainring away from the frame.
4. Reinstall the crankset
NOTE: you only need/want a thin spacer (like 1/32 to 1/16”) or you will have a reverse scenario or not enough threads to keep the crank from hitting the non-drive side of the frame.
I think I bought a bag of thin washers at Home Depot to use for this.
There is another option, it is to flip the rear sprocket. They are typically dished and in most cases are installed with the ‘dish’ facing inward, simply pop off the retaining ring (can be a pain) flip the cog and reinstall the ring (can also be a pain). A pointed awl pushed into the cutaways on the cog will help stretch out the retaining ring (see pic)
Both have worked for me to aid in alignment or provide chain clearance from the frame when running wide tires.
Hope this helps.
