I switched from ES31 14 inch to ES32 15 inch in my recently imported Vitz
While its not a significant improvement to ride comfort, its silent and I can only hear wind noise. My street has those “tough tile” roads and can barely hear them. Feel? Yeah reduced khar khar feel but the improvements were with sound.
Tire size is irrelevant here. If u get ES32 of any size I am sure u will have similar experience. What I cant say right now is how long it will last.
What tires are you running currently?
