Need help with these 19" wheel fitments please
19X8.5 ET25 on a 255/35/19 fronts
19X10.5 ET45 on a 295/30/19 rears or possibly 285 but I'm hoping 295 will be ok
car is slightly lowered
thankyou
I'm moderately low and I'm running 19x8.5" ET28 (ET38 plus 10mm spacer) with 255/35R19 and will rub on big dips. I rub on the flange of the bumper/fender seem (at 1 o'clock in the pick below).

I am either going swap the barrels for another 8.5" which will provide an ET24 without spacers or go to a 9" with an offset near 32-35. Going to another 8.5" will require some fender modification to be completely rub free IMO.
As for the rears, I run a 9.5" ET38 with a 285/30R19 and have no problems. You will have more tire stretch, about 6mm more poke, and slightly taller tire. I think you should be okay with the 10.5" ET45 and 295/30R19. I think there are others who have run that.
im lowered with h&r front springs
is your rubbing upfront a huge problem and do you get much on fast corners?
im currently running 20s with
10.5" rears on an ET42 with 285/25/20
9.0" fronts on an ET32 with 255/30/20
my new setup up front will sit 0.6mm more out the arches and 13.4mm away from the suspension strut
and the rears will sit 3mm closer to the rear strut and tucked 3mm inside the arch then before, according to a fitment calculator I used
I rub when I did a dip going straight. I haven't noticed any taking corners. I imagine that is due to where I rub so taking a right had turn, would put the left wheel turned away from the spot at compression and then the right is uncompressed.
Now as for the clearance of the tire on the 8.5" vs 9" with similar measurements to the fender, the shoulder of the tire is more outboard in the 8.5" while the 9" its inboard and more stretched, giving you the bit of clearance.
So if you aren't lower than me, and have stiffer springs, and depending on the tire brand you use, you may end up not having any or perhaps only a bit like me. Just wanted to pass on my experiences. For me, it doesn't bother me. I know it happens so slow down when I can.
