How bad is a crack in the sidewall?

Jiggles · April 19th, 2014, 05:32 PM

I noticed a very tiny crack circular around the wheel on the sidewall. Not sure if it's serious or not, I just raced on these tires last month.

Doing a trackday tomorrow, am I gna die?

They won't help your lap times.

Just rub some shoe polish in it and it will look like new again

Light surface cracking is relatively normal, but it kinda depends how much / how deep before you can make a call on whether you should worry or not. How old are the tires? (check the 4-digit date code on the sidewall)

It does seem very light and tiny. Can't even feel it with my fingers. I'll check the date code tomorrow, I might just get them switched out at the track tomorrow idk

alex.s · April 20th, 2014, 12:29 AM

what kind of tire

Jiggles · April 20th, 2014, 08:05 AM

Rosso 2

I found r1122 is that the date code?

Also found 4312 is that the date code?

Jiggles · April 20th, 2014, 08:20 AM

Crack goes probably about halfway around

Alex · April 20th, 2014, 08:29 AM

4312 is the date code; it means the tire was manufactured in the 43rd week of 2012. (in other words, not that old). The crack in the pic looks like minor surface cracking, I wouldn't worry about it at all.

I didn't

kirk595x · April 20th, 2014, 10:15 PM

Looks like just a cosmetic imperfection from the molding process. I've had similar imperfections on MX Tires and never had a failure.
