Default Tire experts your advice needed re 2014 IS250 FSport's tire replacement.

Tire experts I like to replace my stock Bridgestone 225/40/R18 front and 255/35/R18 rear.
Diameter of the front and rear is 25 inches, with the front's thread width 7.6" and rear 8.5''

I like to use Pirelli P7 Plus 235/45/R18 94V with larger dia of 26.5 but smaller 8.5 thread width all around.
Apart from the speedo error, what other problems will I be facing ?
I really would like know if this large size tire will clear the under fender without touching ?
Upon visual examination there seems to be 5-6'' space between the top of the tire and bottom of the fender.

I am aware that the car will be 3/4 higher off the ground.
If anyone has done this type of replacement pls help me out.

that... would make your car handle very poorly... and you'd probably rub the control arms

Why do you want to be so high off the ground bro?, yeah that's definitely going to handle poorly..

I wouldn't go anything other than stock OR 235/40/18 & 265/35/18. That would increase your sidewall height, but error would be marginal.

What are you trying to accomplish with that profile?
