Does everyone round the edges off? How much rounding? to the rim?
Do most people leave them stock square?
What are the advantages/disadvantages to each prep methods?
rounding the edges is needed, otherwise the car feels edgy and less predictable. as a guide, most tires come rounded out of the box, i tend to do smaller, while most people round them more. (they are faster)
tire diameter depends on the track conditions and your wallet.
if the track has fast corners, low traction, and high wear, then leave the tires big, just cut them to get the split you want.
for higher traction, slower corners and lower wear, it makes sense to cut them down more.
really fast guys with deep pockets cut tires to just last the race length.
