I don't know a lot, but you may want to consider something like this... Your tires looked very full. I was not able to tell if the tires were spinning, my eyes aren't as fast as they used to be.
I thot the same thing, looked like they could be dropped a pound at least.
Front of springs stiff and clamped, back unclamped and let the leaves spread like the tips of buzzards wings.
You gotta have some initial bite tho-----------with a loose front end , At the present time I haver neither, don`t feel bad!
