[QUOTE="machoheadgames, post: 438543, member: 18789"] It can be a bit trickier than that. Taller tires lessen the scrub radius, changing where the kingpin axis hits the ground relative to the tire. Less scrub radius equals easier to turn. Of course, width of tire and type of tire also play in. A highway tread 9.5” wide tire that’s smaller and leads to higher scrub radius would still steer easier than a 12.5” wide mud terrain that’s taller. I only mention all this to say that it’s not quite as simple as smaller tire = easier steering. The worst offender of any of this though is the wheel backspacing. Downsizing to smaller tires on low backspaced wheels will not handle great. [/QUOTE]
