Not sure I would fit non-standard size to the wheels. Why are you thinking about doing this?
You can mess up the abs system and Speedo fitting tyre's sizes that don't fit the rim correctly
If the physical diameter of the new wheels is significantly different from the factory ones, your speedometer readings will be off. It looks like those tires have a lower profile than the factory R17, so I would advise against them.
If you want to use lower profile tires, you should compensate with the rim diameter, so in this case you should go with R18 wheels.
I've not looked into the tech. data on your 235/55 R17 vs allowed/default tyres.
The key essential factors are:
o Rolling radius / Rolling circumference / revs per mile
o Clearances
On clearance not only a the obvious wheel arch and full lock to lock clearances to all surfaces of importance but the tyre inside wall clearance to strut / shock absorber components. This latter point is often missed as these running clearances can only really be checked with the vehicle on a hoist/up in the air.
Lastly is *dynamic* running clearances.
I'll use my long since gone Fiat Uno SX as an example. I pushed the tyre size to 185 (same rolling radius). All clearances were good/ample EXCEPT on initial inspection the rear axle trailing arm to inner tyre wall. When static it looked OK but I had to do a lot of testing (on road and track) to check the dynamic running clearance.
e.g.
1) static unloaded tyre has a wall to wall measurement of X. This will change to X++ where the tyre contacts the ground. As the tyre rotates it takes a finite time for X++ to return to X. The faster you travel the X++ will reduce to X+ and at a given speed X+ my still contact the trailing arm/other item.
2) Extension of 1) (a straight line case) a car cornering hard not only has an X++ bottom size but also a Y off centre defection. So now we have to allow for even greater clearances. It is worth noting that lower profile tyres can side loading deflect less than higher profile tyres.
My advice is to look up all the tyres measurements/data for your current tyres and then those of the chosen replacement tyre. Now go and look at all clearances on your 500X with the current tyre.

1) 235/55 r17 is 3% bigger diameter than original 215/55 r17.
2) My observation is that with original 215/55R17 speedometer displays approximately 3% higher speed than GPS. 235 tires will fully compensate that speedometer mismatch.
3) Bigger wheels looks cooler.
4) Bigger wheels run smoother.
5) I looked into the wheel arcs and it looks like there is enought space for 235 wheels.
This is why I look on to 235/55 r17 tires.
However before to buy them I whould be sure they will fit.
Unfortunately nobody has experience with that tires size on 500X.

My original wheels are 215/60 R17, so I assumed yours were too. In case of 215/55 it should be fine, that 3% difference shouldn't affect anything much.
If you manage to confirm that the front wheels will have full turning clearance with the 235 tire width, I don't see any other problem with the dimensions.
My original wheels are 215/55 R17.
BTW, diameter of 235/55 R17 are identical to your's 215/60 R17.
Yeah, I figured that much.
I'm using a 225/50 R18 set for summer and its diameter is roughly the same as my original 215/60 R17.
