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.

:confused:

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.

Date code on tire?

Date code on tire?


This a date code?
T312617 GP400A (different on fronts - they had to be ordered) :confused:

Did I get 'old' tires???

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!!!!

All I can say is sticking em in AZ is not a problem. I love em ;)

I had 315 Sumis on an LT1, and they were hard to break straight.. Granted, only an LT1 2,73, but it was tight - with a good burn... They held, and would still chirp 3rd.

The F1's didn't even sound off when they broke... :icon_scra

You hit the curb there ZR1North?

Look for a 4 digit, ie. 1912, 19th week, 2012 man date

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!:o

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

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)

The GS-D3 Goodyear tire may only rate a B+ in dry traction, but it has a couple of things going for it.
1) Wet traction
2) It doesn't get instantly dangerous when the tread is half worn.

it is a little easier to spin cold once you are on the last 30% of the tread, but not nearly as much as some other tires i have owned. Unfortunately these tires in the 315 size are pushing $400 each.

Did you damage something?

I will do a short write up in a few days when I think I am sure we have full recovery but yes, lots of damage when it broke loose.

I managed to minimize the damage when my skid control training kicked in, but not before hitting the curb and nearly breaking the right rear sawblade in half and dislodging the gas metering assembly in the tank. Two rear spindles were bent and the right wheel bearing was toast.

The hardest of the fix was finding a replacement 11" machined-faced sawblade. Thanks to Marc Haibeck's tip and a great forum member (who does not want to be indentified for fear of being labeled as a "wheel ho") I was able to pick up four brand new, never-mounted machined sawblades - many, many thanks, guys!

Allen at Allen Stainless Steel Exhaust in Indiana was able to supply original spindles with rubber bushings and the GM wheel bearing - thanks for the lead, Marc, and for the quality parts and service, Allan!

I am still playing with the alignment to try and reach perfection, but it is pretty much there. I'll keep you posted once I reach nirvana - hopefully in the next few days.

Lesson learned - drive it like an old lady if you have F1s and it's less than 40F!

You have to be careful with any "summer tire" on cold days. This happened locally, to a Z06 on a below 50*F day. http://www.youtube.com/watch?v=WlsPNlGsTJU
I believe the driver made it out, but was critical condition (never heard about the follow up).
