Yes, you will rub with 40s I know couple people running 35s and they get slight rub on hard bumps
I wanted some thoughts on as this set up for 14 Genesis stock suspension.
Front 255/40/20 on 9in wheel +34offset
Rear 285/40/20 on 10in wheel +34offset. I want a thicker tire wall for more protection of wheels from potholes/bad roads and a more comfortable ride but I'm scared of rubbing the fender... not sure if 35wall might be better or if I'm good with 40wall tires. Please help if anyone has used 40 on their tires.
