Tyre puncture

[ade]

My last two sets of tyres where coopers
St maxx. I live in the Pilbra and take my landrovers where
others fear to tred. Never has a problem over some of the
roughest terrain imaginable. My latest set of tyres are
Mickey Thompson stz. Today while out on a standard easy peasy
track I get a flat front drivers side. On inspection I find a small piece
Of wood has gone through the face of the tyre, directly through a snipe
in the tread. When I say small. I mean less diameter than a pen, and it seemed
quite soft when I removed it. My only complaint with the coopers was never being able to get more thang round 40 thou kms out if them with regular care and maintenance.
What are your experiences and comments.
Thanks

There's horses for coarses. You like your coopers, I hated them and then the first set I end up owning because they came on a second hand vehicle. They didn't last 5,000km and I had a blow out. BFG all the way for me.

Maybe you were unlucky with a fluke Mickey T. I know they are soft. I've had a set before and I don't use them now because my fuel consumption went up so much when I changed to them (previous vehicle). They do offer excellent traction but that also because they are soft.

Something else to note is the size of the tyre. Someone will say they had X brand and it was tough as nails then someone else will say they had the same brand and they were soft as cheese.

Check out the "load ratings" here Tire code - Wikipedia, the free encyclopedia and the corresponding ply ratings of the tread.

Check out the sizes for BFG here Mud-Terrain T/A KM2 | BFGoodrich Tires (http://www.bfgoodrichtires.com/tire-selector/category/off-road-tires/mud-terrain-t-a-km2/tire-details)
You'll see LT235/70R16/C 104 Q. Notice the "C" that's a 6 ply tyre but LT245/75R16/E 120 Q is "E" or 10 ply tyre.

The ply rating of the tread makes a hell of a difference. The load rating for the "C" tyres listed by BFG are about 1985@50psi and the load rating to the "E" rated tyres are about 3042@80psi. That's 50% more load rating. I find with the heavier ply tyre I can air down much more off road but the ride is a bit rougher with road pressure.

There's tyres and then there's tyres.

Happy Days.

What he said^^^^^^^^^^^Good example the 235/70/16 AT in BFG is not really LT,while the 245/70/16 is.

Ade,what size are you running?

i have run BFG for over ten years now,never had a flat ever:)

Touch wood.

I'm running 265/65/18. They where on my
New to me d three when I bought it. Had 225/75/16
On my d one. Was thinking of changing the coopers on
My d one to Bridgestone or bfg but then I upgraded to the d three.

Interesting that Mickey T has "N/A" under the ply rating for that tyre in that size. It does list ply rating for most of the other sizes though.

It's Load rating is 110 which is 1,060 kg (2,300 lb) so I'm going to have a guess it's 8 ply equivalent but no idea why they say "N/A" for the ply rating.

Maybe email Mickey T and ask.

I'd be keen to see what their response is.

Happy Days.

Feel free to email them. I can't be bothered
I don't see a lot of point. The damage has been done

Plays are not all the same either. Manufacturers vary in their ply material, thicknesses and the way that they are laid. I recall ages ago looking at one manufacturers tyre which was 2 ply 1500 denier, a competitors was 3 ply 1000 denier.

Well you were bothered enough to post on here. If you cant help yourself don't expect others to.

As for the point. If manufactures don't get feed back, how do they know there's a problem. Maybe they'll appreciate your information and give you a new tyre. Stranger thing have happened. If they don't care about your feed back then that's a good enough reason to shop elsewhere.

I recently bought some Stanley Spanners for my young bloke. I posted on there Facebook page how I couldn't get the spanners out because the moulded plastic tray was too tight of fit. They just said they hope my son likes his tools. I thought thanks tools. Last Stanley tool I buy.

Go buy yourself some Nankang tyres for 50 cents each and don't ask why they puncture.

Sorry if I sound short but I'm having a bad day with the Disco.

Happy Days.

I posted for others people experiences. Not to get into what ply etc
If your having a bad day with your disco keep it to yourself. Was merely stating what had happened. Wasn't planning on going into the science of it or to have some stranger take out his frustrations on me.

Ok. I'm sorry for the way in which I said it but not the point I was making.

If we don't consider why (or the science as you call it) then it's just people taking a stab in the dark. I find tyres interesting and very complex both off road and road tyres.

It's simple and dump thinking that leads people to think wider tyres give more traction. That just simply isn't true on it's own, off road or on road but it's a view taken by so many who don't want to consider how tyres actually work.

What do you care what other people's experiences have been if you aren't trying to find a better solution or option.

A quick check of the Cooper's Tyres pages shows all their S/T Maxx tyres are 10 ply. If you would make the effort to contact Mickey T, you might find out your comparing a much lighter tyre. I which case yes you'd expect it to puncture easier and there's the answer to why it may have punctured with such a small stick. You might be silly in buying another tyre of what ever brand without checking the ply rating because you might find it just as soft. You might be better off just going up or down 1 profile of the next narrow or wider and find you'll get a much higher ply rating.

So in the end rather than everyone reading your thread and finding all these people that have found Mickey T tyres to puncture easy, we get a thread with answers to why people have experienced problems.

Another product of lower ply tyres is they flex more. More flex creates more heat which softens the rubber. Softer rubber wears faster but offers more traction.

Lets be constructive rather than just talking rubbish.

Happy Days.

Applogy accepted. I just posted my experience withy new
To me disco three. The tyres where on it when I bought it and yes next time
Just like the last twenty years, when I but another set of tyres I will be looking at loading and number of ply

[alpick]

Cooper ATR 235/70 R17.

On the car when I bought it about 5 mm tread appeared in ok condition, so maybe 4 yr old.

Hume freeway south of mittagong , temp outside 35 deg, 44 psi, car loaded up for camping and returning home. 110 kmhr.

Started to feel a wobble like steering out of balance then BANG!!

Right rear Tyre exploded, delaminated, .

DSC helped me keep things together to pull over and regathering my wits, change my shorts and check out the damage. Messy but drive able. Didn't know my better half could swear like that! F****k F****k. F****k !!!

Just another exploding Cooper tyre to add the data base. Based on reports elsewhere I would never by Cooper tyres but as it was already there.....

New pirelli scorpion ATR'S going on after it comes back from the repair shop. $2.5k paint repair just a starter. NRMA comprehensive cover will pay for all except the tyre and provide hire car for duration of repair ( and it was the cheapest comprehensive off road car quote I researched - bundled with house and contents and landlord insurance, great service no questions asked just go to repairer and get it sorted.)

Another reason I will never buy Cooper tyres and will stay with quality insurer NRMA. Their premium breakdown cover recovered me to Alice Springs from 300 east along the plenty highway 7 days accom and hire car,for $220!!!!

Off topic - apologies:)

I'm with NRMA too. I was quite surprised and happy when I got the quote for my new D4 HSE which I took delivery of in late November last year. Traded an old Pajero with agreed value of $30,000, the agent told me to insure for market value for the first 2 years to save money as they replace with new during that time, then go back to agreed value. My premium only went up by a few hundred dollars. I was expecting much much more up to a couple of thousand. Same story, got all my insurance with them and have had for years and they repay loyalty with discounts. Also have had no problems at all with claims.
