I have a set of 6 BF Goodridge Trac Edge tyres, 5 on silver steel modulars, one on a standard 110 steel wheel.
Trac Edges are a great all round tyre, between an AT & MT, unfortunately no longer available.
2 tyres are about 10/11mm, 2 are about 7mm, one at 5mm and the 6th is worn on one side but is on a steel modular that matches the rest. If I recall they were 14mm when new. No splits or damage on the sidewalls.
Size is 235/85x16, perfect for a Defender or Series, they will also fit a Disco or RRC with a 2"lift.
Looking for ?250 for these, BFGs are well over ?100 each now. I have had nearly 100,000 miles from a set of these.
Pick up from Drymen G63
