I like the idea of the tires lined up like a giant sound baffle. I have seen that before. At Hap Baker in Carroll county they have shooting boxes you put your barrel/muzzle in to muffle some of the blast. Maybe build a gun box and spray it with rubberized undercoating to help deaden the sound? I would kinda make notes of all the compromises you have tried to make, along with noting any interactions you've had with him. Log the times you shoot. That way if the complaints escalate you have some kind of reference for the LEOs.
I live in central Carroll county, and I am just inside the city line, in a small tucked away townhome community. I can't even legally shoot airsoft or BB guns on my property. However, across the tracks, about 1/4 mile away, there is a farm where the shoot sometimes. Kinda freaked my wife out at first. I told her not to worry about it, as we are in the country, but she asked, "What if we have bullets whizzing by the house???" I jokingly told her to return fire. She has gotten used to it, as most neighbors have, but we have some newer ones who swing a bit left and seem a little bothered by it, although I trued to assure them it is normal, we are far enough away, and its nothing to worry about. I just wish they'd invite me over to shoot over there, lol.
Walk over to the farm when they are shooting, and ask if they need any help. Maybe they'll be neighborly...
