Maxxis Bighorn sidewall split

[keithy47]

So while cleaning the Disco today i noticed a couple of splits in the sidewall of my drivers front tyre, tyres have only done around 7000kms, the splits are about 1cm away from the bead of the tyre, all tyres only inflated to 40psi road use and 18 for offroad. Im thinking the tyre is defective, has anyone else encountered this problem

It wasnt pinched on a rock while offroad was it? looking at the rim near the bead it looks like its had a hard time.

Posibile.

I noticed it's following the the manufacturing line (for want of a better way to say it).
I have seen this on truck tyres when on 2nd recaping.

Any chance of a claim from the tyre suplier given the low Kms.?

Check the insides of them too (the side you can't see easy;))


Cheers.

theres a few things that can cause that. It doesnt look like its impact damage Id suggest that its more likely to be a fatigue failure from running hot and low (high speed beach work) or, gauging by the rest of the cracking on the rubber, age and UV exposure.

[big guy]

Looks like some sort of fatique/manufacture fault.
Check the others and ask if its warranty work?

This can happen to any tyre manufactured at some stage, hope no one just jumps on it and labels them rubbish now as they certainly are not.

Similar happened to some Coopers tyres and they were ridiculed.

I hope they sort it out and you regain some trust back in the tyres as that is what counts when heading bush.
Trust is a must when heading bush or for that matter just down the road to get the local paper.

the remained of the tyre in that top pic looks dry and cracked all over, looks more like a really old tyre that has been in the sun a long time, not a tyre that has done 7000km

agree 100%

Looks like fatigue resulting from a manufacturing fault given the age. Looks like the wall is about to separate from the bead. Have had this happen about 10 years ago on another now very popular yank brand. It was replaced under warranty.

Look for the tire manufacture date yuo may have been given old stock as the rubber looks like its old and has been run soft and gotten hot even the white lettering looks a tad yellowish and ive never seen that in 3 years of buck shots

I have never seen it in any tyre, im with lokka on this, they look as if they are old stock or something, as i said before they look all dry and cracked. I would be taking them back as soon as you can and make the person you bought them off aware of the problem so they can get it sorted before they get to bad.

I had a complete set of Cooper ATR's replaced under warranty (I had to pay pro-rata on the km's already traveled) for a similar fault.

No explanation given but I wasn't keen on Fraser Is. salt water getting in there!

The Simex's fitted on my P38 when I bought it had similar (longer/wider) splits on 3 tyres. They were replaced under warranty with no questions asked - and I didn't even have the receipt from the previous owner.

you gotta love that, now thats the kind of service that makes you go back to a place and buy your next set of tyres.

[Basil135]

It does look like an old tyre.


Have a look here: Aged Tyres (http://www.bridgestone.com.au/tyres/passenger/care/age.aspx)

[isuzurover]

As others have said, the tires look old. What does the date stamp say?

See link above. The first 2 digits are the week and the 2nd 2 are the year - e.g. 5207 would be the last week in 2007.

I would be interested to know what the retailler and/or Maxxis say about it as I have bighorns as well.

No chance the tyre(s) have been exposed to a lot of ozone? As this would accelerate the aging process.

[keithy47]

Had a look and it looks like 4 of tyres are 0109 (including the split one) and ones is 0209. Im going put the spare on the drivers front and take the split one to the tyre place i bought them from when i get a chance. Im learning towards a manufacturing defect, just by the fact there are several splits all the same distance from the bead. Will see what they say.

[keithy47]

Update:
Well i fitted my (brand new) spare for saturdays run out to jelore SF, after stoping to check my pressures and air down i noticed the same side wall splits appearing in the new tyre.

thats got to be either old stock tyres or a manufacturing defect. If any of your rubber turned up on anything but a stores trolly (and even then I'd still have a crack) Id have them XX'd and a new pretty DO NOT USE sticker smack bang in the middle of the drivers vision area of the windshield faster than you could say "Hey Farey what the hell do you think your doing?"

[Psimpson7]

That's awful!!

What have the supplier said?

[keithy47]

I will be speaking with the supplier (well known retail tyre chain) tomorow morning.

[MickS]

Make sure you start with the store manager mate, not the tyre changer. Good luck and keep us posted.

They are cheap for a reason

[dullbird]

They are cheap for a reason

I wouldn't consider bighorns cheap!!

I wouldn't consider bighorns cheap!!


cost me $245 each for 255/85/R16


They are cheap, but remember a tyre is a disposable item


my 7.50 are more expensive,but better on road, better in the wet, better at highway speeds etc.....

[dullbird]

I dont think they are that cheap....I paid 250 for 245/75 but was originally quoted 270 and others have been quoted close to 300 I wouldn't call that cheap....


my mongrels were 180 now thats cheap......and silverstones are cheaper than maxxis...and BF's are only mildly more expensive for the old pattern.

what make are your 7.50's simex?

[dobbo]

what make are your 7.50's simex?




All around the same price regardless of brand roughly around $250 per tyre, mine are Goodyears, replaced 2 after one delaminated after 7yrs on the car (and being a tubed tyre it still got me the 5km's to the tyre shop, couldn't stuff it anymore)

[Ace]

Regardless of price Maxxis is a well known brand and it shouldnt be happening. It shouldnt happen with any tyre for that matter, especially after so few KM's.

have you been to see the dealer? Are they being replaced? I think lokka hit the mark, they have to be old stock, they must have been sitting in a yard for ages somewhere or something to have cracked like that.

[isuzurover]

They are cheap for a reason

They are certainly a lot cheaper than MTRs (which they are almost a copy of). However, the tyres in question were manufactured in the first week of 09, and tyres should have a "shelf" life of at least 6 years.

Mine were made in 07, and they show no signs of the above. So unless the tyres have been stored in pure O3, I suspect a manufacturing defect.

[stevo68]

I paid $320 a tyre at beginning of year.....plus they were just pipped at post by the new KM2's in a recent tyre comparo of 20 odd tyres. That aside...I haven't had any probs with mine....do 500+kms a week and then nail them bloody hard at least once a month off road.

Regards

Stevo

Like all things you get what you pay for, but for something like a tyre its not like a cheap chinese toy that you say oh well i should have spent a little more and got a better quality one and throw it out, tyres are a matter of safety and that isnt acceptable from any tyre.

I recenly bought a set of the new Goodyear MTR's with the kevlar in the sidewall to see how they went, yes they were expensive, but time will tell as to how much value for money is in them.

[keithy47]

Well i spoke with the store manager today and he agreed that it is being caused by manufacturing defect. He is going to contact the Maxxis rep to organise 2 replacement tyres.
I think it could have just been a bad batch of tyres.

[alien]

Good to see that things are happening for you.

Is it worth getting the outher 3 striped off the rim and checked for intenal damage?

Worst case is cost of 3 punture repairs but what about peace of mind?

Cheers,Kyle.

good to hear, it would seem that is the case, there isnt really any other explanation.
