Tire Sizing

[u/MrUnlimited24]

Hey guys quick question and looking for advice. I currently have a 2011 SL550 and with stock 18in wheels. Will there be any issues if I go down from the stock staggered setup of:
Front: 255/40/R18
Rear: 285/35/R18
To a new setup of:
Front: 245/40/R18
Rear: 275/35/R18
Reason for the move is because of limited choices on the stock setup. Any advice or recommendations would be greatly appreciated. Also would like to hear what tires you guys prefer as there’s so many to choose from.

I would not. You’ll have less rim protection and your speedo will be off as well.
