F1 'stickiness' (or lack thereof...)

[Schrade]

I got new F1's, and the rears broke loose the other day. Kinda' surprised me here. Hammer was NOT to the floor, and blacktop was dry. THen later, I saw hardly any markings on the road.



This happen to anyone else with this model rubber on the corners? Is F1 a 'hard' rubber?

Cold pavement and cold tires no sticky!!!

If you're referring to the GY F1-GS-D3s, like Big John said, "no sticky".

I've had them for about 5 years now, and I find that much below 40 degrees they're pretty pathetic. And, it gets worse as temps drop from there, I find.

In retrospect, I had just fired it < 1 minute before, and of course, the blacktop was cold too (Gore let me down on another Global Cooling Winter & Spring)

Interesting! I have the same observation/complaint. I take the point that the warmer the pavement and tire, the better; but I expected better from such an expensive tire.

Last October on a cool dry afternoon, I accelerated hard in 2nd to activate the secondaries as I had done at least 25 times before in the same location (on a up-hill grade) and much to my surprise, the back end broke loose - unlike the previous 20+ times when I did it with cheap Sumis on - often under the same temperature conditions. $4,500 later with new wheels and many rear suspepension parts, I am finally undoing the damage from that fateful October afternoon.

WIth less than 200 miles on the F1s, I'll keep them and hope I am happier at the end of the summer. At the moment though, I am not impressed!!!!

Oh, believe me, I'm not meaning to sound like I'm dissing them. They are fabulous in summer temps (as a street tire), and I credit their ability to hold most of their grip on wet pavement to saving my bacon once. (Met a pickup taking his half out of the middle on a blind, wet pavement curve. I wuz already pushing it a little. But! Suddenly I had to change my line - pretty drastically - in mid turn. The F1s bit without a whimper, as if to say, "What? It's just a little water!" Obviously, I was impressed...AND grateful!)

I can live with their short comings in rare below 40 temps for an occational winter outing. But, they ain't up to snuff, and these short wheel base cars can flip ends QUICK if you're not kerfull!

I agree. They're a super summer wet/dry performance street tire.
