Tyre Wear - Is this normal?

I've been using these Insa Turbo Dakar (remoulds) for 18 months, probaly 70% on road, 30% off. I noticed the pair which were up the front have developed splits through the tread blocks as shown in the pics attached. Not totally through the block, but perhaps 30% in? The main one running the entire length of the centre of the tyre matches the rubber 'mould' bits that are still attached to the main tyre body - you know, the flappy bits of rubber that just get left behind! Others are still in the same direction, following the tyre rotation, but not central.

To be honest, I'd be happy if one of these went pop, 'cos I plan to replace them with larger Khumos (probably) when these expire, but of course it'll happen at the most inconvenient time!

Ta.

hello mate as a ex tyer fitter trained by good year dunlop and a commercial fitter the cuts to ur tyres are more than likly to be caused by the speed of which you are driving at they are remould and will have a speed rateing normally lower then a new tyre anfd when you drive above this speed the tyre will slowly break up i had a pair of dirt devils that did the same its called delamination

happens a lot with commercial remoulded tyres

hope this helps you mate

Looking at the photos - and bearing in mind I have no relevant training of any kind - to me those cuts look like, well - like cuts. perhaps from spinning up the wheels on rocky ground?

My understanding of delamination (again, not backed up by any training or specialist knowledge) is that it causes the tread to lift off the carcass??

they look like cuts to me as well, mine are covered in them due to wheel spin on shale and rocks. you spin a wheel on a sharp bit and you get a nice cut in the tread a few mm deep on every block over the whole circumference of the tyre.

this is delamination

Nice tyre... hope mine don't do that any time soon. Checked the speed rating for these, and they are rated 'S'... and in a diesel Disco I don't imaging I'd ever get close to 113mph, and I can guarantee I haven't even tried :)

Anyway, most of the lanes around here are flint/chalk based, so I guess the trend is that these are cuts rather than splits. Hope I can make them last until the next bonus payment then?!
