Thread: Simex Centipedes on a Disco1

Thanks Pete, your Disco looks great in that photo.

Having driven on the Centipedes for a couple of days now I've become aware of an alarming grinding shudder when pulling up. For a while I was convinced one of the wheels must be about to fall off but could detect nothing wrong. Today I checked the tyre pressures and discovered they had ~46PSI in them. The fitter told me he put 36PSI in them so I hadn't bothered to change them to 'normal' pressures. Now I've dropped them down to the pressures specified for the Michelins which is 34PSI at the rear 28PSI at the front. Initial roadtesting shows a much quieter ride and no shuddering when pulling up so hopefully that was the right move.

Well despite everything looking good on the road-test and on the 'cross-axled on the ramps' test, things did NOT go well under real off-road conditions.
The tyres rubbed (if thats the word for smoking rubber and mangled metalwork ) on both the front and rear wheel arches. The straight camel cut I used is not enough at the rear and the tyres were even having a go at the front part of the rear arches - the bit that's covered by the rear doors. There is some rubbing at the front as well but that may be fixed by a little tweaking of the lip. The tyres themselves have had some parts of the outer lugs removed when cutting into the metalwork.
The problem seems to be not so much the size of the tyre as the way the lugs protrude at the outer edges. More investigation to follow.
