My 2022 Mazda cx5 has p225 65 r17 tires on it.
I have a good set of p225 55 r18 snow tires.
Can I put those on my car?

Thanks

 

If you have the wheels and they have the same offset then yes, you can. The car is sold with both 17" and 19" wheel sizes.

 

Wouldn’t you just want to run it through a size calculation chart, make sure the circumference is identical, odometer settings ABS sensors etc?

 

You'll need wheels with the right off set and bolt pattern. Otherwise, they should work just fine.

 

No, he cannot put 18” tires on 17” wheels. That is what the OP asked, he said nothing about wheels.

lol. he asked if he could put them on his car, no mention of wheels....message boards can become a little confusing...

 

It would actually be very easy to put 18" tires on 17" rims. No tire machine needed.

 

I agree Carpe' and Alan - ,,,,we all know that contingent upon which trim / level you acquired - either 17/19s- Most may need 2 get the dogs tennis ball and bite firmly whie reading -
The17" or. 19" refer to the DIAMETER of the rim itself - if measuring a line from one side to the other passing directy over the midde ( center cap ) . The 17" will be ..(17") , and the 19" will be (19") - thats perddy dang straight forward ....Now The interesting thang is if you measure a straight line from one end of A mounted 17 or 19 TIRE ( on the respective 17" or 19" rim) either size , from the top of the tire to the road - ( over the center cap) this DIAMETER will be the same for either a 17" or a 19" rim - -

 

yes thats true, the model is designed for different size wheel. different profile tires, 50, 55, 65 are used to make the circumference/ diameter the same, this way there is no need to recalibrate, ABS sensors, odometer, speedometer and whatever other parameters are measured by tire revolutions per mile. the profile is a measurement, a percentage of height of the tire to width which will only change the height of the tire outside to bead. lower profile tires handle better but can produce a harsher ride and more prone to damage from potholes, and just the opposite with higher profile tires. so the circumference will be the same for all model trims even though the wheels and tire diameters measure the same

 

IMHO, assuming you have the correct wheels, this size is still not recommended for your car as the 225/55-18 i s 2.8% smaller (20mm) in overall diameter than your stock tires. The rule of thumb I have used over many years of doing +1, +2, (or -1 conversions for snow tires) is to stick to +/-1.0 to 1.5% difference in diameter, especially in AWD cars, but with all modern cars these days with sensors and safety systems designed and calibrated to the manufacturer designed tire size.

The largest difference I have ever gone on AWD is 1.5% from 245/50-17 to 255/40-19 on wheels with appropriate lighter weight, wider width and therefore offset, which I kept to within 2mm of stock without any interference.

The perfect size 18 inch tire size for you would 225/60-18, which is an insignificant 0.4% larger.(2mm)

I use this site for visualizing wheel and tire differences. It has particularly helpful to me in the past when calculating offset changes.
