No tires for OE 215/50/18 - replacement recommendations?

My 2016 CX3 GT will need new tires soon. The selection for 215/50/18 tires is non-existent and the prices are horrible.

Looking at alternatives, it looks like the 235/45/18 size is less than 1% smaller than 215/50/18. Is that something that would fit on the stock wheels?

If I have to replace the wheels, what size would you guys recommend? I'm willing to sacrifice handling for increased ride comfort. Should I switch to 17" or 16" wheels?

Hi, I think the 235/45/18 will fit fine, another size to consider is 225/50/18.

I have attached a few sheets showing the comparisons.

Here's a site you can plug-in sizes.

There won't be a significant difference without carefully calibrated equipment while the car is being driven by a professional on a recently re-paved race track.

Just have a look at the sticky at the top of this sub-forum and have fun searching.

The 235/45/18 tire requires a 17.5" min rim width, so it looks like it's not going to fit. Will look at 225/50 in more detail but looking like I might as well change the wheels.

The sticky is nice, but doesn't answer what I asked. Thanks for pointing it out though.

For years, Yokohama has been my go-to tire brand. I recently bought a set of 225/50/18 Advan Sport A/S. For me, they were the perfect choice for a replacement tire; the cost was about $740 with mounting, balance, and road hazard.

I just replaced two of my original tires (the other two will be replaced wihtin the next month).
I considerd changing size, but found several options in the orig. size, among others Continental and Michelin makes tires in the orig. size.
I went with Michelin Primacy 3. They do very well in tests and I have used their winter tires for years.
The price is about the same as a 225/45-18 tire, so no real reason to change size.

I just put 235/50-18 Michelin Pilot Super Sport tires on my OE rims and they mounted up easy. Rides like a dream.
