Can someone please let me know if this would work?
225 40 19 FRONT AND 255 40 19 REAR

Would the performance change at all, and would this damage the car?

 

Anyone???I am from Canada

 

yes it will work and wont be a noticeable change if you're sticking with the same tire. The only way you'll notice a change is if the new tires are better or worse than the current tires.

yea it will work. ru on oem 19's rays??
i have the same setup, 225/40 front and 255/40 rear.

 

Yes. It will work.

 

Have seen others with that size as well.

 

works fine

 

Touch taller than oem but probably within acceptable limits.

If you are running coupe wheels on a sedan, I'd recommend 255-35-19s though

 

this would be way to small size for both coupe and sedan

 

No it's not, that's what Im running.

 

Actually no it is not.

Sedan
245-40-19 is a touch bigger than the 215-55-17

255-35-19 is a touch smaller than the 215-55-17.

Obviously a 255-40-19 is a touch bigger than the oem 245-40-19.

255-35 isn't revelant to the coupe portion of this discussion

I've done all the leg work already.
