I'm expecting to take delivery of a road fitness bike that uses Alexrims DP17 rims (the 700c sized rim).

I can't seem to find any information on recommended tire sizes to be used with the DP17 rims. Also, I can't find information that indicates maximum (tire) pressure that can be used on these rims.

Alexrims website (https://www.alexrims.com/) doesn't appear to have the required information(?)

Does anyone know what tire sizes and maximum pressure that can be used with the DP17 rims?

I think the tires and tubes are more of an issue than rims, as far as inflating pressure goes. Go by the tire specs.

I presumed that rims designed for certain tire sizes should handle the respective tire pressures. But, I'm aware of comments posted in various places on the internet (don't recall specific websites) that mention the possibility of exploding or breaking rims due to (excessive) tire pressure. So I asked the question regarding tire pressure for the DP17 rim just to be sure.

Another consideration is the pressure rating of rim tapes also. Tires should not (in theory) be inflated to pressure exceeding pressure rating of rim tapes and rims (whichever has the lowest pressure rating). An example was a 23c tire that had a pressure rating of 145 PSI that I fitted to a wheel. The wheel had rim tape pressure rating of 130 PSI, so I could only inflate the tire to 130 PSI as I didn't want to risk higher tire pressure rupturing the rim tape.

I haven't found specific recommended tire sizes for the DP17 rim, but I have found other information which helps (to a degree).
