My dads has the same problem, and small cracks in the tread, spoke to LR :they are not covered and speak direct to conti.
Someone came out from conti and explained that the wear is normal and to rotate tyres to get equal wear!
Small cracks could of been caused by running under inflated tyres so are not a claim, it's done 15k and tyre pressure is always checked and all 4 tyres have small cracks.

Replacements will be Michelin from Costco when the time comes.

I had Conti's on my old SC, slid all over the place in the snow and ice and even caused a slight Venture off road into a fence. I replaced them with Pirrelli Scorpions which have been great all year round. Currently have Scorpians on my TDV8 and they are still good and even after 48,000 miles! (Motorway driving mainly)

got conti's on mine with shoulder wear. had x2 lots of alignment and a front to back swap and plan to wear them out in the couple of months! have a set of scorpions in the garage ready to fit - cracking tyre on and off road 3.0 VSE - 2015MY
Corris with Black, RSE, 22 turbines, privacy, deployables

A new set of Scorpion Zeros fitted last week after 50200 miles on the previous set. They were down to 2mm on the front and 3mm on the back.

I had quotes ranging from £944.00 to £1600 for a set plus fitting etc. had them done at the local Kwick Fit for convenience at a cost of £1,054.00 after a bit of haggling. Current MY2020
Gone: 1 x L405 and 2 x L322's

My dad put them in his £600 from camskill and £50 fitting at ATS he's very happy with the improvement, conti was more of a road tyre that wore very badly
