Probabally a bit late to be asking as i have 2 on with another 2 too follow

I notice the 15 inch tyres are still a lighter construction than the 16s and even the 16s have one less tread ply than than the old MTR

I had major problems with sidewall damage with the old MTRs (absalutly no tread puntures) copping around 10 sidewall punctures in the 4 1/2 years i ran them. pressures seemed to make no difference with puntures being copped at all pressures from 40 to 15 psi and pressures in between

i considered the new BFG tyres but in the end the kevlar in the sidewalls swayed me

Im hoping the new kevlar in the sidewalls has rectified the weakness in the old ones

typical scenes from most trips which involved leaving nicely graded gravel roads

I've been using the old MT/Rs for the last ten years on four different 4wds & have never had a problem with them.

I went to order a new set the other day & was quoted $450 each! I think I will look around for something a bit cheaper!!

Dave Douglas in Alice quoted $450 each for 285/75/16.

My last set was 265/75/16 for $349 each in Windsor western Sydney.

I reckon at $100 more each is a bit much & I've been hearing some not very complimentary comments about the new MT/Rs from travellers passing through here.

what sort of things? you often get people expecting different things out of tyres,

being more aggressive than the old MTrs their probabally noisier and the high silica compound compramises grip with longevity - same as the old ones.

I wouldnt expect people to have issues with them driving on gravel roads

there is always going to be a big price hike for 285s over 265s

even $349 for the old ones is a bit rich in Sydny _ i would be expecting more like $300

you can still pick up the old ones in perth for just over $300 priced only last week

We had a bloke here last week who had a lot of chipping & cracking in the tread area of his new MT/Rs, so he took them back to his supplier who showed them to the Goodyear rep'.

The rep said that this shouldn't have happened & replaced two with Duratraks free of charge, he's not real happy with the Duratraks either!

Bridgestone A/Ts are not much better, I got two sidewall punctures on my last trip almost identical to your photos.

Got them for $250 each though.

Just a little insurance for you, my daudhter and son inlaw have a mechanical business in the weatbelt in WA and they have the Kevlar wall goodyears on their triton as they were having problems in the stubble left by havesting puncturing sidewalls since trialling the goodyears they have no more problem and have around 80,000 klms on them so hopefully this will work for you.

I had the previous MTR's (265/75R16) on my GQ LWD Patrol and never had any issues with side wall punctures. i was extremely happy with them - while on trips with other people getting punctures from bad cattle grids, staking, etc we never had any issues or flats. the worst I had was a bad cattle grid tearing a lug (which I later had vulcanized to repair it) - other people were getting flat tyres/punctures form the same bad cattle grid.
Im on the new MTR's with kevlar now - yes DAMMM expensive but I was lucky to get them while goodyear had a sale so the price went form $425 to $375 each.
The new ones are much more aggressive so they dont roll as well - I've recorded slight increase in fuel consumption from the old to the new.
In the sand they are fantastic - I've been on soft sand with them down at 18PSi and there is little sidewall bulge - all increase went front/rear which I was really happy with, one of the guys with us had mickey thompson MTZ's and they were at 18PSI as well - they had appallingly bad side wall bulge - I thought they were down at 10PSI they bulged so bad - they were fitted to a Disco3...
On the road they have been great - when perth had the massive storm pass through I didnt have any sideways pull as I drove through puddles - which I had on the previous model of MTR's..
So im really happy with them - doing a big trip to Carnarvan ranges in Aug so we will see how they wear/handle with the camprite camper and car fully loaded for that 2week trip in the bush...

Gday Davoe,
You've done well to stick with the Goodyears. When you're doing that sort of damage on the old MTRs which had one of the thickest sidewalls of any tubeless radial tyre, then I'm a little pessimistic about how you'll go with anything else.

I've bought some Federal Couragia A/T in 235/85R16 for my TVan and might buy a set for the Landcruiser. In this size (and a couple of others) they have a 3-ply sidewall and they are cheap - mine cost $225 each. Not sure what they cost in 285/75 but at that price I think they are worth a try. My daughter's 80series runs Federals and they are a good tyre - quiet, don't chip and she's had no punctures.

Hmmm ive heard them mentioned before. Dont know if I could get them locally but I would have tried to price them at least

I guess with that cut the sidewall held up as it didnt go flat.

still not sure when i did it as i had done alot of beachwork and would have thought id notice it when re inflating

The photos you have posted show exactly the reason i changed about 3 years ago from MTR's to Mickey Thompson MTZ's.
With MTR's both my son running 33's on his hilux and myself running 285/75/18's on the 80 series experienced a series of sidewall puntures when sticks hit the shoulder of the tyre and where then trapped in the open sidebiters to end up infilcting a sidewall puncture which in most cases rendered the tyre US.this is because the sidebiters are between the tread blocks.
On MTZ's with closed top on the sidebiters( they align with tread blocks) the sticks are deflected off the shoulders or at worst punture on the shoulder ,a pain but at least the tyre is still repairable.
I believe its a treadpattern design flaw not a ply strength issue
wouldnt pay the money they are asking to even try the Kevlar MTR's.

the sidebiters are completly different on the new MTRs

as i said i picked the new ones up for about the cost of what most other tyres are going for (except for cheaper brands)

Gday Howard,
Yeah, it seems to be the sommon spot where tyres get staked - BFG have it all the way round. the tyre below copped 3 stakes - you can see where its been plugged.
