Winter Tracking Tires ?
 

Can anyone recommend an all season tire (not a winter snow tire) that is sticky below 50 degrees F ?

In for:popcorn:

A snow tire will be MUCH better in the cold than an all season. They run softer compounds to maintain grip in colder temperatures.

If you want less squish, get a performance snow instead of an ice/snow. You'll find similar compounds, but with tread blocks designed for dry pavement more than deep snow or ice.

Still looking -

Anyone know of an all season tire (no cleats) that works at below 50 degrees F., and is stickier than average road tires ?
A winter snow tire would dissolve at ambient 40 to 50 F. on the track.

I don't know the answer to your question. But it brings up another question. Many tires say they are not to be used below a certain temperature. But you're asking about a track tire. Wouldn't a summer performance tire heat up to an acceptable temperature on the track?
Why would you want an all-season tire for track use? Are you planning on driving on a track with snow on it? I think providing very specific details of the venue and conditions might help you get a more accurate response.

I am asking about an all season tire, not snow, or track tire.
Very specific conditions are - pavement under 50 degrees.

A simple quest for an all season sticky tire, as I will be tracking from about 25 to 45 degrees F., and snow tires melt and the cleats rip off (except when the 4x4 Subie club rents Mosport after a snowstorm) !

Ambient temperatures don't matter at all for a tire. What matters is track temperature, and how much heat you'll be able to get into the tires.

At 50F (10C), any typical good summer tires will still get plenty of heat on a track. At 25F (-3C) you're might be below what a ZII/RS3/Rival/RE11A/etc will need for heat, BUT if it's sunny out the track temp will probably be high enough to get them working well too.

Are you just lapping in the cold? Have you tried typical summer tires yet and found they don't build enough heat? You can always drop the pressure a few psi to help build some heat as well.

I know at an autox last weekend it was under 10C but when it dried out there was lots of grip on typical summer track/autox tires.

^^^what he said^^^
If you're on dry pavement driving hard, I'd steer clear of A/S tires. Go for summers.

Yea I'm going to a few track days in next few weeks. im sure the mornings will be below 50 degrees and even still dark out since I'll be swapping tires at 630 AM.

Never had a second thought about using my 200 tread wear tires. heat is a hell of a thing. ambient may have a large impact on something that has air running over it (radiator, etc) but I have a strong feeling (i.e. broscience) things that have a lot less air such as tires and brakes are not effected as much.

But as I said, I don't have much experience and haven't experienced "cold" temps yet. Soon.

I tracked my ZII's around 10* C in the rain (OTA school in early May this year) and they were totally fine.

I've run Michelin Pilot Sport AS3 on the track at 40 degrees with no issues. On the street the coldest temps I've used them in was mid-20s.

What does the term 'average road tire' mean to you?

I tracked Direzza Star Spec's at between 3 to 8 degree's C and it took 6 laps of driving on a skating rink to warm up the tires, (5 laps to late) while being out cornered by Prius tires LOL !

My Direzza ZII's have been tracking since last May and are now bald and have to come off.
I want to replace them with an ALL SEASON (not a snow) tire that is noticeably stickier in the cold, so I can go fast in the cold.
The twin goes to bed during high salt and gets new ZII's for high summer.

Experience with sticky all seasons, anyone ?

What about these? http://www.nittotire.com/passenger-tires/motivo-all-season-ultra-high-performance-tire/

I know @ Dipstik-sportech has them on his car right now. Maybe he can chime in.
