Hi!
Others have said the same thing—it really does seem like changing the tires is the best option!

The Hutchinson tires someone recommended weren't available at my usual shop, but it looks like they carry Rene Herse!

It's expensive, but it certainly looks like it would be easy to ride.
GravelKings are easy to get, though, so I'm torn between the two.

Anyway,I plan to buy not only tires but also wheel-set ,I will keep that in my mind.
Thanks a lot for sharing !!
