I thought these tires would be true to size on my 18mm internal width rims.
I measure 35mm after install.
Do they stretch out over time?
Are these the 38s? I've heard from sources that the shortened the casing size some time in 2018 so all the gravelkings(slicks and SK) would measure "true to size" on modern wheels(whatever width that means). My 38c gravelking slicks from last year measure 40mm+ on 17mm internal width rims. This seems to confirm the change. I'll have to find a new tire that is closer to 40-42mm slick for groad use.
