As Harry mentioned too fast on rmoving urethane or to kuch pressure actually overheats or in my terminology cooks the tire. It really has a negative impact on the grip. Also i always glue the tire to the wheel before truing to avoid any slippage.
Take your time and do it for as long as it takes withiut overheating the rubber.
Without a machine be very cautious of the pressure applied and do both tires at the same time.
If it takes an hour to get it right ,
it may gain you 10ths on track, do it in a rush and gain nothing
