Tire break-in miles?

osbornsm

Hello all,

I just picked up a set for Toyo R888 for the track.

How many miles would you recommend driving on the tires to "break them in"?

I didn't think it wise to go hot lap on brand new tires.

for me it takes about 50miles, but depending on how u drive it might come sooner then that, or later.

the best way to tell for me is to make a fast-ish turn and if the car feels disconnected front to rear, it needs more break-in.

It depends on whether you are referring to "heat cycling" race tires or manufacturer recommendations for breaking in any new tire. Generally speaking, new tires require 500 miles to get through their break in period. Consult your factory's recommendations for properly heat-cycling race tires as those will vary.

wow 500miles will take me like 2yrs. lol

You're looking for proper heat cycling on track, NOT break in. You'll need to look up toyo's recommended heat cycling procedure. If you don't heat cycle properly you can ruin the tires and they'll go greasy really quickly on track.

If you buy your tires from the Tire Rack, they offer the option of heat cycling the tires for you, that way they are good to go when you get them.

Yeah just talked w tire rack... they say $15 per tire for heat cycling.

Also here is the Heat cycle / break-in procedure for track tires.

1. Get tires warm without spinning them (no burnout / drift).
2. Let tires cool overnight, preferably not on the car.
3. After 24 Hours has passed... enjoy!

500 miles to "Fully" break them in.

I was going to ask the same question ^ that seems a bit high.

No no no. This is for street tires. Do not confuse street tires for R comps (which are sometimes street legal if they are DOT approved)

Give this man a cookie and close the thread please before we get more stupid advice from people who don't know the difference between dedicated track tires and street tires.

This is road tyres in normal DD .. it takes somewhere between 100 and 500 miles to scrub off the mould release agent used during manufacture and also a few heat cycles for the structural changes in the rubber polymers to be activated for best tyre life (road tyres are not optimised for grip - their primary optimisation is for life and that means resistance to heat cycling).

Race (or semi-race which is the R888) as pointed our earlier in this thread require a different process which is basically put the tyre through a heat cycle for the polymerisation to occur and then scrub the tread surface to get rid of the release agent and you have best possible grip - R-Specs and slicks "only" get worse (lose grip) thereafter.

You guys in the USA are lucky in that Tyre Rack will do the heat cycle for you.
