I have a 1987 Bounder P30 with the original size R8 19.5 tires. Have done a ton of work, new tires, coil springs, leaf springs, shocks, bell cranks, tie rods, track bar, etc but still hate the way this thing handles at speed. Just wanders all over the place. The shop that did my alignment says these narrow tires will aways be problematic and handle poorly on this suspension, so I am looking for alternatives and have a few questions:
#1. Has anyone upsized the tires and wheels on their P30 and if so, what were the results?
#2. As I understand it, these require at least a 6.75 wide wheel, and these wheels are only 6. Can you safely run this size on our wheels, or do you have to downsize to a 225/70R19?
#2. Is there anyone who makes a steel, or even aluminum 6.75 wide wheel that fits the P30 chassis lug pattern and hub? If so any links or part numbers would be appreciated!
#3. With respect to alignment, I'm running about +.25 toe per side and +3.0 and +4.0 caster, and I know these numbers have a big effect on high-speed stability which is my biggest problem. Any thoughts on if my current setup needs to change?
Thanks for the input!
