It does!
It’s because of the 275’s. The wider the tire up front the more they tend to seek out ruts and imperfections in the pavement and start to wander around. 225’s don’t need that much caster to be stable.
With 275’s between my Challenger and my Duster I’ve run between about +3.5° all the way up to +8° for caster. I’ve found on my Duster that with less than +6° the front wheels start doing what they want instead of what I want, they’ll start tracking ruts and things. It’s not terrible but it becomes more noticeable as the caster decreases. I’ve also found that when I go past +7° the steering effort at lower speeds starts to increase exponentially. So I shoot for around +6.5°, at least on my car that seems to be a happy medium to balance tire wander and steering effort. Nice and stable at speed on the freeway and I can still park it at the grocery store without tearing a bicep.
