Tire Break-In

The Ecsta V710 does require break-in. New tires will be slippery for their first laps, and will begin to feel better as they get scuffed in and build up heat. We recommend that drivers heat cycle their tires 3-5 laps before using them in competition. Heat cycling helps you get the most consistent performance and tread life out of your tires. It is the process of gently bringing the tires up to temperature for a short duration and letting them cool. Ideally, you should break in your tires, remove them from your vehicle, and set them aside for more than 24 hours before your track sessions and races. Often this requires running a practice session on new tires to prepare them for a future race, while you use tires prepared previously for the current race. The Tire Rack offers an automated heat cycling service which can complete this process before your tires are delivered to you.

Are you using them for competition? If not, you could just heat cycle them early on a track day.

+1.

My track tires when they are heat cycled by TireRack last longer than when I do them. And besides them doing it on rollers with consistency, the key is: An important heat cycling step is that after being brought up to temperature, the tires require a minimum of 24 to 48 hours to relax and reform the bonds between their rubber molecules.

unless you intend to race them outa the box then no.Another point with dot R compounds is shaving...you should shave them to be more consistant and to actualy last longer....how much depends on how many mm of tread they start with.

I was going to use them for my de4 events. I don't want the down time of only doing a couple laps then having to swap the tires during my 20min session.

Usually heat cycling helps improve the life of tire but at the cost of peak grip.

If you're going for a qualifying lap, go with stickers.

honestly with the RA1 I'm used to, I'm not sure that heat cycling from the dealer was crucial.During any day of hpde the tires will peak and trough,you just have to adjust your driving style depending on grip.I have no experience with the kuhmo.
