Which option has higher impact on FC?

225/50 has larger circumference but 235 also adds a little to circumference but also wider so more drag, no?

Why upsize...looking for a bit more sidewall for comfort and also a slightly beefier look

using goodyear excellence now. I find the ride pretty harsh I want max comfort by swithcing to best comfort tyre and a slight upsize since this is a family car. but dont want too much penalty in fc also. now even my smaller car is more comfy using conti UC6.

1st - Consider upgrading or changing to comfort base touring tires like Primacy/Turanza/Advan Db/Ventus Prime 3 etc tires first..

2nd if already done that and felt the sidewall still stiff, consider downgrading your sport rim from 17 to 16 if still got space to downgrade.
225/55/16 or 215/60/16 would be alternate choice but do take note when comfort side go up, handling side will go down.

I've used yoko advan fleva, michelin xm2, Gy excellence, and Conti UC6... what better in comfort and noise above all these?
