I have been reading with interest all the good things that have been said about MTR's
Sidewall strenght seems to be a real selling point.

My question is how do the Silent Armour Tyres compare in this sidewall area. I'd be using LT265/75/16

The Good Year site seems to be light on for Tech data, does anyone know what the ply rating is?
What sidewall "bulging" am I going to get at 25 psi @ 4+ tonnes.

The actual construction of the Silent Armour (SA) sidewall is 2-ply vs the MTR 3-ply, but both have all the "puncture resistant tecnology" blurb written on the sidewall. I would guess that the SA is not as thick in the sidewall, but have no way of being sure.

But, SA have a higher load index than the same size (265/75R16) MTR (122 vs 119), so they are like the old 10 ply vs the old 8 ply for whatever its worth.

I managed to puncture one last month, which I never did with the MTR, but we had 2 vehicles with Silent Armour doing the Hay River and Madigan Line, so nothing unusual there.

The sidewall don't bulge very much - its a pretty square shoulder. And I've found already that I don't need to air them down as far as I did with my MTRs.

Still reckon the MTRs will probably be a stronger tyre.

Cheers

Yeah I just got back from a small trip down south in WA exploring for a large campsite for our 4wd club to do a large group overnighter.

Now normally down south doesn't offer much trouble in tyres, however I was going along some old logging tracks and ended up actually getting quite lost, even with Ozi on the laptop!! (I know it's embarassing! who get's lost in the South West!). Trouble was, none of these old logging tracks were on the maps and they are scattered all over the place in some quite steep country, they started getting worse and worse and even though I could have followed the GPS to where I started I was running out of daylight and didn't really have time to back track the whole way and then get to my campsite before dark so I pressed on as according to the GPS I was only about 1km away and 70m above the main forrestry track that I needed to be on to get to my campsite!

I really gave the MTR sidewall protection a real workout IMHO, some of those tracks where very overgrown in places with branches and sticks all over the place. I bent two antenna brackets and put lots more scratches on the surf. :-)Lot's of turning around on dead end tracks in the scrub and driving over fallen down trees and old piles of wood. MTR's are no worse for wear after some real punishment.

I still love'em and the grip on that marble gravel here in WA still just amazes me everytime I drive on it, I've never experienced a tyre so good on it. The only downside that I can see is that on nice graded roads driving with 29psi in them I still make massive grooves in the roads, probally doesn't impress CALM or local shires much, but they are brilliant for traction. The advantage though is you can always tell if you've gone around in a circle cos you can see you're own tyres tracks! ;-)

I see a lot of posts on MTR and now SA - does anyone use the Goodyear Wrangler ATR? The tread pattern seems to be a compromise between these 2.

I'm currently using the AT/R ... Had 'em on desert sand, gibber, mud, & everything in between.. (very little gen-u-wine cross-country though)...
Been running these for a coupla yrs, and have no reason to be dis-satisfied with 'em, but I think I'll go for the Silent Armours when replacement is due ... Main reason being that the SA looks to have a better shoulder profile than the AT/R... On very low pressures, the AT/R exposes a bit too much side-wall to the ground for my liking...
I suspect that the introduction of the Silent Armour may have sounded the Death Knell for the AT/R......
