Putty Posted May 28, 2009 Report Share Posted May 28, 2009 So I have a set of Z rated 30 series tires I run in summer months. Oddly one is flat. I pumped it and noticed a crack, if you will, on the corner, that is releasing air pretty good. Not the side or the thread..the corner. I slid a plug in it. It's holding air, but is it safe?

Snowflake Posted May 28, 2009 Report Share Posted May 28, 2009 I wouldnt trust it at Z rated speeds... Quote Link to comment Share on other sites More sharing options...
verse Posted May 28, 2009 Report Share Posted May 28, 2009 They say you shouldn't put plugs in Z-rated tires, but I probably would do the same. If you want someone to put a plug in it, post the area you're around or go to Derek at NTB. I could patch/plug it in Hilliard. Quote Link to comment Share on other sites More sharing options...
Crossle Posted May 28, 2009 Report Share Posted May 28, 2009 If it is not "In the tread" technically you should not plug it for fear of tearing the sidewall and making it worse/ it not working at all. On the other hand, I did plug a LT tire on a work van probably in the same place you are talking about and i have not heard otherwise from the guy and i see him almost every day.... If it goes flat, new tire, if not....meh, don't do Z rated speeds lol. Quote Link to comment Share on other sites More sharing options...
Guest tbutera2112 Posted May 28, 2009 Report Share Posted May 28, 2009 hit about 80 and cruise for a few mins...thats how i just found out my tire was bad lol Quote Link to comment Share on other sites More sharing options...
Putty Posted May 28, 2009 Author Report Share Posted May 28, 2009 I plugged it and it is holding air. I have not put them on the car yet. I didnt want to bother if it was not safe. I don't do Z rated speeds, so that isn't an issue. I just dont want the hassle of it going flat and needing a tow.....at the wrong damn time. I don't feel like buying a new tire at the moment...before you ask. Quote Link to comment Share on other sites More sharing options...
Cordell Posted May 28, 2009 Report Share Posted May 28, 2009 If it's leaking from a crack, I'd be replacing that before it cracks more and shreds. I wouldn't risk it. Just an FYI, if you patch a speed rated tire technically it reduces it's speed rating. Quote Link to comment Share on other sites More sharing options...
starkmaster03 Posted May 28, 2009 Report Share Posted May 28, 2009 Was it cracked like from dry rot? If so I would not trust it but other wise I would trust it even though at the shop we are not allowed to plug it. Quote Link to comment Share on other sites More sharing options...
Putty Posted May 28, 2009 Author Report Share Posted May 28, 2009 I could not tell if it was dry rot. How the hell else does a tire crack? These tires/rims sit all winter long and I switch in the summer. I've never seen such a thing. A damn crack. Quote Link to comment Share on other sites More sharing options...
Cordell Posted May 28, 2009 Report Share Posted May 28, 2009 Tires crack from dry rot, defect, or just pain old junk. I don't trust cracks, how many tire caps do you see laying along side the road? They aren't all from big trucks. Quote Link to comment Share on other sites More sharing options...
nurkvinny Posted May 28, 2009 Report Share Posted May 28, 2009 No, you should not run a tire that has a crack plugged on the edge. There, the obvious answer first. Now, my real answer... only one way to see if it is going to hold/last... Quote Link to comment Share on other sites More sharing options...

TTQ B4U Posted May 28, 2009 Report Share Posted May 28, 2009 Tires crack from dry rot, defect, or just pain old junk. I don't trust cracks, how many tire caps do you see laying along side the road? They aren't all from big trucks. yep....they just ran a story on the news about old tires being kept and sold in inventories. Shelf life they say is like 5yrs. personally, I wouldn't run it at all. especially since you're carrying more precious cargo than just your butt. BTW....post some pics of the cargo daddy. enjoy those moments. Quote Link to comment Share on other sites More sharing options...
verse Posted May 28, 2009 Report Share Posted May 28, 2009 I didn't see where it said it was in the corner. I'd probably just replace it. Quote Link to comment Share on other sites More sharing options...
TurboRust Posted May 28, 2009 Report Share Posted May 28, 2009 a tire is probably cheaper than the new rim you'll eat up crusing 70 down the highway. if you had a nail in the edge and it was a puncture I'd tell you to plug it and forget it. but cuts/slits/cracks are bad, they just spread.

Akula Posted May 28, 2009 Report Share Posted May 28, 2009 Take it to Taylor Tire, they have a balancer that takes it up to z rated speed (and are VERY knowledgeable about these things) Quote Link to comment Share on other sites More sharing options...
Dave1647545494 Posted May 29, 2009 Report Share Posted May 29, 2009 post a pic of the tire it sounds like you need a new one, but hard to tell without looking at it Quote Link to comment Share on other sites More sharing options...
