I do 8 reps with 4 wheels on either side, is that respectable

My grip starts to fail before my back and legs.
I'm going to keep increasing the weight untill i can get 6 wheels either side for 8 reps then i'm gonna stick on it. I'm gonna do this with bench press aswell when i get to 3 wheels either side. No point going any higher because you will wind up getting injured.
