Here is a different take on a tire question - I have seven Firestone Transforce radial tires 225/75/16, load range E, that are six years old. I want to take them off my GMC for age. So, if my 2004 Ford Ranger 4x4 pickup calls for 245/75/16...is there a design or engineering factor I may not be aware of that would make them unsuitable to switch to the truck? The Transforce probably have 10,000 miles on them, and I would do all five on the truck so spare would match (and replace the 16 year old original spare). I would expect at least 4 years of service on the truck if suitable.
The inflation chart from Firestone goes down to 35 psi, which is close to the 30 psi Ford recommends.

I understand the tires being an inch shorter (resulting in truck being 1/2 inch closer to ground) and speedometer change, and a bit higher RPM, but I'm curious to learn factors that go in to this. Would they ride like bricks or soften up at lower psi? Thoughts?
Here is a handy dandy comparison site also:
