Im looking for replacement tyre on my Corolla Cross Hybrid.

Currently on stock 225/50/18 Toyo CR1. Going to be replaced soon, mileage 51000km.

Searching for same spec, all prices above rm500.
But 225/55/18 seems much more cheaper. Can get less than rm500

Can i replaced with it? From on9 tyre calculator, doesn't run far from the speedo speed.
Yes it does give slight higher profile.
