I’m new at this to. So the point of cutting tires is to get them flat across or do you put a angle on tire for handling
There are many different reasons to cut a tire.
Typically on a thick rubber tire like a Burris, you can "shape" the tire's contact patch to better suit your needs.
Round cuts, flat cuts, and a whole myriad in between.
Then there's rubber thickness and how it affects the tire, heating, cooling, prep absorption, and more.
Spring rates are also affected by cutting the shoulders of the tire: thinner = lower spring rate, thicker = higher spring rate.
Cutting tires affects the handling of the kart, especially as the track surface changes. Higher bite tracks need flatter cuts, lower bite tracks need rounder cuts. Some chassis also like particular profiles when it comes to tires. Flatter cuts can free a car up.
You can camber cut tires to better match the stagger in the rear axle, but it is seldom done except for specific applications like syrup racing.
Concentricity is really the least of our concerns when cutting a tire.
There's even more to it, but that's the basics of it.
