255/60 R20 Tyres

The current range of Pirelli Scorpion ms tyres do not appear to be fit for purpose! I have had several punctures over the past three years all of which have been a small piece of road gravel piercing the centre of the tyres.
On each occasion the gravel has gone through the rubber, canvas and even the metal gauze.
Unfortunately after 30 using Pirelli I think I will be changing manufacturer.
All of my cars on this period have been new Land Rovers/Range Rovers with tyres fitted as original equipment

I have just under 50K miles on this set of OEM tires, and there is significant wear - especially the front tires. Most of the miles are highway miles in west-central Minnesota. I drive 50 miles to work 3 days per week from a rural lake location - about 10 miles on back roads, the rest on well maintained 4-lane roads. They are decent in snow, but slush and ice are a challenge. They hydroplane easily on wet roads. They work fine for light off-roading.

Have those Goodyear's on my LandRover Defender P400 SE X- Dynamic!
