Hell, it's not even a motorcycle. A friend has an MTD Yardmaster riding mower with a flat tire. Tubeless, but it's a sidewall cut. He can't get the wheel off. Rear wheel, left side, 1 bolt in the center. Pulled the bolt out and now it looks like the next step is to get a big hammer and start knocking the wheel off from the inside. I am just no willing to take the next step. The whole thing looks under engineered and probably won't receive the big hammer appraoch well. Any suggestions?
