Well folks I finally had to bite the bullet and get some new rubber.

Still 54,700 miles on the original Wranglers isn't too bad.

As the tyres came off we measured the remaining depth at 3mm on the shoulders 2mm in the centre on the rears and 4mm on the shoulder with 3mm centre on the fronts. The wear was very even and no sign of feathering on any of the shoulders.

Anyone in a position to improve on this  Stornoway Grey GS ... What a fine motor ... but not any more ... ... psst look at my gallery!
Company cars ... a thing of the past - May 2013.

I'm on my 3rd set of fronts and 2nd rears at 31500

On 17,000 at the mo, running on 4mm fronts and 5mm rears. Reckon I'll get 20 - 25K Gone - TD4 XS Auto, Sumatra Black, Mud flaps and side strips, clear indicators, private plate, privacy glass

Rears replaced at 31,500mls - Fronts on 4mm.

Still don't understand why the rears have gone before the fronts considering the weight distribution (Engine, steering etc.) FL2 TD4 XS Santorini
