SPendrey Posted August 26, 2010 Share Posted August 26, 2010 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.

dazwell24 Posted August 26, 2010 Share Posted August 26, 2010 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 Quote Link to comment Share on other sites More sharing options...
SPendrey Posted August 26, 2010 Author Share Posted August 26, 2010 Thanks for the feedback... I have used them once or twice on the motorway, not exceeding their rating I'm sure, but anyway I take your point especially as they're not really a road tyre.

ThreeSheds Posted August 27, 2010 Share Posted August 27, 2010 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??

nicks90 Posted August 27, 2010 Share Posted August 27, 2010 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 Quote Link to comment Share on other sites More sharing options...
SPendrey Posted August 27, 2010 Author Share Posted August 27, 2010 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?! Quote Link to comment Share on other sites More sharing options...
landroversforever Posted August 27, 2010 Share Posted August 27, 2010 Scott, I cant remember which one you were burning out on the waffle back in January time.... One of those? Quote Link to comment Share on other sites More sharing options...
SPendrey Posted August 27, 2010 Author Share Posted August 27, 2010 That's a good point, it was these. Certainly a possible candidate for the reason why. Thanks Ross, well remembered. Quote Link to comment Share on other sites More sharing options...
