yer i dunno, i got used to Flows and yesterday back on 717s (same tyre size) cornering didn’t feel right at all BUT that could be pressure, tread, carcass or several other things. get wider rims if you can afford it they just feel better with any tyres imho. or try yours, nothing really bad will happen, the tyres might just roll (sideways) more than you like. also maybe more likely to get pinches or in extreme cases roll off but unlikely if you keep pressure reasonable (but then bigger tyres want lower pressures so you’re back to wanting wider rims).
ardent 2.4 is a really big tyre btw but yeah try it.
