I have a 2001 sl500 stock tires are (245/40ZR18) front and (275/35ZR18) rear I am running 19" now with 245/35/19 front and 275/30/19 rear. I am going to go with 19x8.5 in the front and keep the 245/35/19 tire and the rear im going to use a 20x10 what size tire should I use 275/30/20? I would like or 285/25/20?

Luke@tirerack

the size that would be correct are

245/30-20
275/25-20

but, they do not have the proper load capacity and are not recommended

But I would like to have 19 in front and 20 in rear

Luke@tirerack

if you did that the rear sidewall would have a different defflection rate than the front which would have an adverse effect on the cars handling
