Question from someone without a ton of experience in swapping out wheels/tires for road or offroad driving: how much does scrub radius matter?

I was trying out this tool below (mentioned in another thread) and it said "Scrub radius will be changed by 30 mm, this may affect the car's handling." From doing some reading, there are articles explaining the term and how it can affect handling, but it seems as though most people think it's not very important in terms of real performance.

Hi Nick,

You can count me as one that thinks this affects handling.

My Ranger hugs the road better than almost every other vehicle I’ve owned in the past, it’s hands down the best handling truck I’ve ever driven. That being said I personally wouldn’t do anything to alter Fords steering geometry since It does so well from the factory
