Can I do 1 more Track day with my rears RE-11?

scruffydog · 01-20-2013, 08:53 PM

I don't know if I can do 1 more HPDE track day coming up in Feb 3rd.

I have pretty much no tread left. Any input would be helpful. Thanks!

Also, another question. For Tread measurement, am I supposed to use the wider marker (left side) or the thinner one (right side)?

DEpointfive0 · 01-20-2013, 08:54 PM

Lol, that's not tread, I think you won't have enough traction

They're not designed at racing slicks, lol

Here are more pics

scruffydog · 01-20-2013, 08:55 PM

thanks for the input! I will get replacements then.

Shamu · 01-20-2013, 08:59 PM

Lol you have more than enough for dry day! Don't change them unless you Need wet tire. Little sketchy for wet driving.

DEpointfive0 · 01-20-2013, 09:02 PM

Lol, I'd trust Shamu or Spohn or chrischhorn over my opinion

scruffydog · 01-20-2013, 09:03 PM

I'm confused...so will I have enough traction? I think it'll be a dry day on Feb 3rd. I'm gonna be running Hi intermediate group. I won't get to the pt where wires will be showing right?

Oh okay, thanks! Here are my fronts, hopefully I'll have more than 1 day for the fronts...

If its dry, you will be fine. as for which bar to use, I think its whichever is the worst, but you aren't going to blow a tire or anything. I run Hoosiers until the first one cords.

Like a man! Lol

Japanjay · 01-20-2013, 10:19 PM

Should be fine. I know of several guys that will shave tires so they can still compete in classes that require a DOT approved tire.

djtodd · 01-21-2013, 12:01 AM

Agreed. Traction wont be worse. Probably better than a new tire on a dry day.

cossie1600 · 01-21-2013, 09:50 AM

not sure about track days. but they are definitely slower at your tread level in autox for me. still. it is plenty safe, especially given how good your edges look. u will be fine as long as it isn't wet

I see a differences when the edges on these tires wear out. not in the middle so much. I am on re11 #9-12 now

The bigger bar vs small bar is ~0.0300" different in height. The bigger bar is higher & closer to the perimeter of the tire; the bigger bar always reads to be less (worst); this is true all around the tire.

Prior to my last track day @ T-hill:
FD: 0.1295"
FP: 0.1105"
RD: 0.0500"
RP: 0.0350"

Now:
FD: 0.1155"
FP: 0.0880"
RD: 0.0285"
RP: 0.0095"

Ride them until you see a cord, mine only got faster.
