For W203 C-class with Brabus Monoblock VI 18' 8.5 Front and Rear,<br> Can i go with 255/40/18 tire size for the Rear?( 225/40/18 Front )<br> Is it possible? Will it be more comfy than 225/40/18 all 4s?<br> <br> Thank you.<br>
Re:lee2375: Use a 255/35/18 in the rear. That is recommended.
Thank you lee2375. Why can not put 255/40/18 in the rear? How about 245/40/18? I need the ride more comfy on the tough road. Do you think 35 series is too thin for that? need suggestion again thank you.<br> <br> Brabus Monoblock VI 18' 8.5 all 4s
You need to keep the OD of the front and rear tire as close as possible. (more)
Generally speaking, if you go wider in the rear (an avergae stagger is 20-30mm) you would need to drop 5% in the aspect ratio to keep the sidewall height the same. The 5% drop in ratio compensates for the added section width. Therefore, the sidewall height on the 225/40 and 255/35 should be close to identical. Remember, sidewall height is a function of the aspect ratio and the width. A 40 series tire will not have the same height in all widths. It is simply 40% of the width.
