In over 20 years I have never had sidewall damage and I have done some stuff where I thought the tyres would not survive and they came out unscathed. Always in the past been on 16-17" rims running 32" tyres. I also have some chips out of my front left rim (factory 19"), I'm assuming this happened in the sticky spot. It probably lifted some rocks out of the track when it lost traction and spun. This just goes to show that the low profile tyres are extremely vulnerable and susceptible to damage along with the rim. :( Cheers, Babs :D Sent from my iPhone using Forum Runner

Just now noticed another cut in my sidewall.

The first one was rear drivers side this one is rear passenger side.

Mega ****ed :(

Disappointing! :( Still, they stayed up, and we will never know what those particular rocks would have done to a tyre of another make.

I can't see how their sidewall rubber would be softer after going to all that trouble to make them LT and hard wearing.

I have been driving those track and worse in that region for years on Coopers and BFG and never ever had tyre damage.

I had a mate a couple of years ago slice a sidewall on standard Hilux tyres and put it down to a freak incident but not now, I'm now convinced the Coopers and BFG are a lot tougher tyre in the sidewall.

For the driving I was doing this should not have happened. These are bulldozed tracks no ruts or steps just flat tracks, the sticky bit I was referring to with regards to slipping was due to the incline, this is steep country but you couldn't ask for a better track.

Example of the terrain in this photo.

A lot of loose rock but nothing big.

I'm putting it down to the low profile and brand of tyre being weaker in the sidewall. In saying that it still probably the best choice unfortunately for a 19" rim :(

Pardon the spelling mistakes in the previous post.

Here is another photo.

A mixture of fist sized rocks and no bigger.

In over 20 years never a problem. Now one drive up and two slices. :(

Would you have used 42 psi in the other tyres or did you keep the pressures up on the 19" to avoid pinching the shorter sidewalls? At 42 psi the sidewalls wouldn't have much give. Lowering to around 30 psi may have been a useful compromise.

It's not good Babs. I have done 30kph on heavy gibbers in Sundown National Park fully laden... Sharp hard rocks and no dirt... Just rocks. Combined with hours of slower driving on the same rocky roads. My Maxxis 751 LT are completely unscathed from that. Sorry to see the tyres cut mate.

Cheers

I didn't take photos of the heavy rick areas but even this part had a lot of sharp stuff. Cheershttps://www.aulro.com/afvb/images/im...016/10/814.jpg

When mine are due (18'' Freelander 2 ) I will be probably tossing between these two.

A relative had Yoko ATs on and said they were OK for about 50,000 ks, but then he switched to Toyo ATs. Not sure what that proves - OK but not great, I guess.

Yes Graeme I have always kept the highway pressure on the previous tyres only letting down pressure for rock steps and driving up the rocky creeks. The tracks hasn't ever been any real need for the drop on bulldozed tracks.

And yes from research I was of the understanding that retaining higher pressure on the lower profile tyres reduced the chances of sidewall damage.

Trouble is when you air down already thin rubber the rims just look SO close to the ground. It's a conundrum because with them up the tyre will not deform around sharp objects and pop back... It is more prone to damage with full pressure. Likewise full pressure puts more stress and shock on the carcass, rims and ultimately suspension. Cheers
