I forgot to check clearance for this spot before ordering tires…
Swapping out the tires on a new to me bike and having some rubbing troubles. Is rubbing in this spot a result of the second measurement (40c) being too big or something else? Hoping that swapping to 700x35c would help. It had bontrager H2 700×38 tires on it before and they were fine clearance wise but they had smoother tread. The new tire is a Panaracer Gravelking SK+ 700x40c if that makes a difference.
I Haven't replaced tires until now so sorry for the rookie mistake. I'll probably use this tire on the front and get a different one for the back. I just want to be sure to order the right size for the back since I already messed up once :p

A wider tire will also have a higher profile. With bicycle tires, they only list the width, not the height, in the sizing.
It will help, but I honestly could not tell from pics if this will be enough. Rn it seems to be unusable with this tyres. Which could mean that even 35mm will be cloooooose. And, I talk by experience, a close tyre plus some debris could result in a nice crack at the BB shell. Go to lbs and check
a side view would help but yes 35 will likely fit.
Is there any clearance at all? A 35 may be ok. I have the same lack of clearance (I have like 2mm or so) with 50mm gravel kings but a 45 is fine. This was the 50, and in my next reply …

What was the original tire size?
That’s rubbing a lot. Don’t think a 35 would be much better.
Yes
This is a bit drastic but that chainstay bridge’s only job is to support a fender. 15min with a hacksaw and a file and it wouldn’t be a problem anymore.
I blame the Internet, people front like you can’t ride down that bike path without buguns
Move the wheel back at the axle bolt Or quill clamps.
Slightly off topic but do we have the same bike? For reference I have 700x38s on a 20 inch frame

35 smooth or 32 knobbed.
35 smooth will not pick up as many rocks.
You could also go for a 584 rim with wider tires or have the bridge put higher by an experienced welder if it’s steel.
Also, for the love of god, oil your chain
What wheel size is the frame buit for? If this is an old steel MTB frame from the 1990-s, it might be for 26″ wheels.
You could try 27,5″ but as you can see on the photos, 28 (700c) might be too big.
Is the wheel all the way back in the dropout?
