Car is Camry ACV40 2011. Orginal rim/tyre was 215 55 17. few years back changed to 18" with the following specs

rim = 8.5x18”
tyre = 225 45 18

after checking https://tiresize.com/comparison/, the circumference and wall were reduced by -1.1% and -14% respectively. From there, it seems 235 45 18 tyre size is closer to the original size except for the width (wall improve from -14% to -10%). I think 235 45 18 can be used and would like to know others' opinion as well

Thanks

speedometer difference doesn't really matter, the difference is still not significant enough to make a difference

assume you use the same tyres model as the 225/45/18

when you use 235/45/18, you will feel softer sidewall (bit more comfort) and higher rolling resistance since 235 has more contact with the road, and probably increase your fuel consumption too

225/45 on 8.5 is stretching the sidewall a bit, so for the same tyre you will feel more responsive handling using 225/45, but of course the traction wont be as great compare to 235

Hi there,

I had a quick look on my inch up table here and yes 235/45R18 should fit for your case with a tolerance of -3% +4%.

in the link above, I also describe the pro's and cons on doing so. Hopefully this helps.

Thanks!

thanks for the input.
