I used 84 Ford Ranger rear/axles, 4 bolt, 15 x 7 on my trike. Tire size is 215/65/15. If my rims Mustang, 4 bolt) were a bit narrower (6") I would have used 205/70/15. But the difference wasn't that much as I changed gearing to 3.00. If needed one can re-drill the axle, install 4 studs. We're not running 600 horsepower on these trikes.
Run rear tire pressures from lows of 12-16 (left/right) to 20/22-24 (left/right) and front tire (40). Rear air shocks about 40-ish lbs. Front air fork pressure: 5-6 lbs.
My trike is a 1985 GL1200 Aspencade, narrowed Ford Ranger rear with a 1996-8 GL1500 MotorTrike body. Also installed 5 degree steering. I built it in 2008 and is still running great.
