How to break in UMP mod tires

[timcole421]

I have new D's and New A's, how should I go about on a break in/heat cycle on these tires before sent out for the A-main?

Depends if your trying to gain stagger or not.

Put em on and run them. No break in required.

They'll last longer,not chunk out on rr and feather less if you run a heat race or 2 on them and wash them with simple green before you set them out for a high heat cycle in the A, unless u buy em at the track we never put on a green tire then run a feature.

Simple green will make you fail tire tests from what i hear.
