I think it may be worth a shot since tires are relatively inexpensive. Is there any caution against mounting 32 or 35 tires onto an 19mm rim? My bike came with DT Swiss P1800 splines. What advantages would I have to getting a wider rim down the road if I wanted a dedicated entry-level gravel set? Do wider rims mean even lower pressures?
