Bro you asked same question in QQ chat.
I am one of the QQ change to 235/55x17 and it is totally fine. Some more the diameter of this size is same as 215 so it wouldn't affect the speedo reading.

Haha thought this was a more appropriate place. Thanks again!Bro you asked same question in QQ chat.

just MHO
changing the tire size is acceptable is conversion is a recommended one by vehicle maker or tire maker
For QQ case it is ok to put 235/55/17 instead of 215/60/17 and some one had high lighted the overall diameter is same (so speedo meter reading is not affected )
MY view is If you original size is available so no reason size change ( some WS might just simply pushy because they do not have them in stock )
putting 235/55/17 my concerned is can your currecnt take the wider tire? ( base on my technical research this 235/55/17 can mount on rim width from 6.5 to 8.5 inch
ideal width for 235/55/17 is 8inch
Just my personal POV

Both cost $212/pc
3. Bridgestone Dueller $196

as what bro marcostan said, it is ok to change to wider tyre (as long as your rims follow appropriately) because will not affect speedo reading. It's only those that change to larger diameter wheel (rim + tyre) that must pay attention to more things like wheel well clearance etc.
But! do note that the handling of the car will change because suspension geometry changed due to wider rim (not so much of issue with a bread and butter car);
However, your fuel consumption would also be higher because got more rolling resistance due to wider tyre contact patch (a bit more issue with bread and butter car), though the increase wouldnt be SO significant.
in car, all parts of the car affect some other part in both big and small ways. as long as you dont push your car to the limits and drive normally, a bit of change here and there will be ok.

Increase in unsprung will increase FC

I never quite figured out this wider tyre = more contact patch thing.
Using newtons law of equal and opposite reaction. its the psi of the air pressure that determines contact patch no?
e.g. psi x contact area x 4 = weight of car

Do not, I repeat, do not use wider tyres n bigger rims unless yr car has sufficient torque. wider means more rubber touching the tarmac, and increases FC, road noise, slower, difficulty in revving. Some cases, tyre may even hit the inner fenders(front tyre) when you steer.
Wider tyres only can feel the benefit of stability if u drive like 150kph or above, where that extra cm helps. If u dont drive up north, forget it.
Just follow maufacturer specs. Been there done that.

ya correct .
using wider tyres dun mean more contact surface , or more grip.
it only change pattern of the contact surface. example. rectangular to square. or to rectangular another direction.
wat it does improve is the corner stability. cos of the width .
but the result of lower profile tyres mean a more bouncy ride. more often then not. it decrease the grip, instead of improveing it.
f1 is a great example. see their tyres where got low profile. ( they still testing)
if talking about grip, low profile mean more 'chio' , nothing else.

use these 2 online rim/tyre calculators to check the sizing and fender clearance

the respond to this topic is Good
I didn't know buying a tires lots of thing to consider
so if you worry
Follow what is fitted originally (from Car manufacturers)
Or optional tire size from your car manufacturers recommendation (check this info from your car owners manual or Label on your car)
to me
bigger is not necessary better
speedo meter reading is not everything
Quality is the most important and my priority

A good rule to follow is change all or change none.
So either stick with all stock, else change both rims and tyres. Don't do half past six, keep rims and change tyres.
Wider tyres may not fit on your rims, do check the guidelines. Yours is currently 215 so likely your rims are 17x7. To go up to 235 recommended you use 8 inch rims, min 7.5

It's so amazing to see 1.2 turbo and 1.5NA with 18",19" & 20" tyres.. Super cool looking 😂👍🏻👍🏻Do not, I repeat, do not use wider tyres n bigger rims unless yr car has sufficient torque. wider means more rubber touching the tarmac, and increases FC, road noise, slower, difficulty in revving.
