Precise Tire Question
need a pro for a detail:
Tight fit...ET
Will it fit?
Front
Now: 18x8 225/40-18 ET34
NEW:19x8.5 225/35-19 ET30
My Bilstein PSS9 are REALLY close with my current
wheels up front
Rear
Now: 18x8.5 255/35-18 ET30
NEW: 19x9.5 255/30-19 ET35
Do you think it will rub on a W209 AMG?
If my math is correct: up front I have a -4mm ET=
meaning my new wheel is 4mm closer to my fender.
and my rear: I have a +5mm ET = meaning my rear
is 5mm closer the my shock
and I have 4cm of space between my current
rear tire and my shock... soo I may be able to put
some 265/30-19 and some 225/35-19.
Am I correct?
I know it's a long and precise question.
but Worth a shot.
is it a good idea to put 225/35-19 with 265/30-19
on a W209 AMG
Thank you very much for taking the time

Your math is not correct, it is a little off.
For the front, you are right the offset is different by 4mm, but your new rims are wider, so it is not 'just' 4mm closer to fender, you have to take into account the .5inch or 12.7mm (6.35mm/side). So rim alone is pushed out to the fender by 10.35mm by the rims alone, before taking into account the difference in tires. Different brands/models of tires have different measurements so there is no easy way to calculate.

Wow, great info on this detail.
I did not think of the wider rim (8in to 8.5 in) good to know
It's going to be REALLLY tight up front
Soo I HAVE to keep 225 front beccause of my PSS9 OK
Next:
Has for the back...
Could I be running 265 ? keep in mind I have 225 in the front with the PSS9
or the 225 with 255 is the best combo?
