The title says it all. It’s late October 2025 as I type this and between now and Spring of 2026, I’ll be replacing the OEM Yokohamas G91A’s on my 2024 CX-5 Select.

I've been thinking about a slight upsizing from 225/65-17 to slightly wider 235/65-17. Tire Rack says the wider tires will fit without any problem. But I’d like to know if anyone has upsized like this and noticed any particular upside or downside as a result. Handling? Braking? Fuel mileage? Anything that comes to mind.

There are a number of tires I am considering, including the Goodyear WeatherReady2 and Pirelli Scorpion WeatherActive as all-weather options… or the Continental CrossContact LX25 and Pirelli Scorpion AS Plus 3 as all-season options that still do well in winter.

Thanks in advance.

 

Upside going to wider and taller tires , you may feel a slightly more confident braking and handling, downside is your MPG will likely be less.

As far as tire tread pattern and brand you ONLY can decide based on reading the technical information and tire reviews. This means before you look at any brand or tire write down on paper what you want from top most important to you to the least of about 6 things. No more or less then do your research.

Most that give advise about tires is based on very very very limited experience to compare more than 2 or 3 tires brands and tread design . The shelf is long with how many tire variations in each of the numerous brands available.
I am not saying that recommendations are to be disregarded only that they will lack depth of experience.
You also can not really on another person having exactly the same service condition Mazda ,driving style as you do and where their driving road and environmental conditions are when reading recommendations.

 

While the MPG is going to probably suffer a little bit, my other concern would be that the car will not be reading completely accurate with the mileage and speedometer. It would be a small error but still noticeable.

 

The GPS on the heads up display mapping only displays real MPH to which you can adjust your throttle reposes to compensate.
The tire size the OP is contemplating would only change about 1-2 mph at 65MPH? Natually you would need to use a speed tire calculator for the correct ,
MPH difference.

 

I would only ask ..why ? I personslly wouldnt alter the oe spec tire size - while there may be adjustments in the hud or whatever to get the correct mph - its still changing the rpm ratio of the transmission to the engine,- its a precision engineered component - the driveline- - as well the suspension ....but its your call

 

235 65 17 is an optional tire size rated for the CX-5 with factory 225 65 17 equipped tires.

See Mazda model year tire optional sizes Mazda USA website.

Sometimes this information may be in the drivers door jam of some vehicles which pertains to tire psi.

 

Are you saying some CX-5's with 17" wheels have 225 and some 235? I have never heard of this when there are no optional wheel tire packages (which I have never seen on the CX-5). Also, it's my understanding the correct tire to pick with an OEM 225/65/17 size would be 235/60/17 to keep the approximate ratio the same. But as others have said, it's a pretty small difference.

 

Read again what I said!!! exactly...

 

Why was the question - but 65% of 225 is greater than 60% of 235 so its not the same - may be no issue - ? but i go oe unless its a battery etc
