Excellent.

I bought a new Samsung TV on offer in Leclerc a few weeks ago and the girlie asked me if I wanted to buy extended warranty (as they always do) - I said exactly the same 'does it need it then' answer was "no" so then I won't have it was my reply

 

I can add my own personal experience with this. Granted, they weren't Yokos, but I had a set of Treadwrights put on a D1 back in 2007 at a Wal-Mart service center. During the install, the shop manager came and got me and asked what was so special about the tires. I told him they were standard retreads and there's nothing special about them. He headed back to the garage bays.

A few minutes later it sounded like a shotgun went off in the building. I just stepped into the work area when it happened and my ears were ringing. That was the sound of the bead seating at well over 100PSI. All four tires did that. It scared the new techs, but the guy mounting them said he's seen it happen on other Land Rovers, but didn't know if it was the tires or the rims that caused it.

My guess is LR wheels are on the large side of the tolerance window for the rim diameter and some tire manufacturers are on the small side of the tolerance for the rim diameters.

 

Could be the bead retaining ridge on the wheel. I think this caused damage to my old tires when they were REMOVED to install the Yokohama tires. I think my old tires were bridgestones.

 

I am going with wheel design. I have never had such difficulty removing a tire from a wheel as I have while dismounting on a professional tire machine. Getting them to bead was a bit of a chore also. I have a sneaking suspicion LR designed these wheels as to let tires be run at a lower pressure without as great a risk of unseating the bead. The crappy summer sport truck tires that were on it when I bought my Disco were torn to shreds when a "tire tech" unmounted them. I decided to do my own next time (it's nice having friends who own shops). Even with bead lube, the BFGs fought me coming off, and the Coopers fought me going on.

 

If you look at genuine LR wheels and measure them you'll note they are a tad larger diameter with a higher ridge which is effectively to bead lock the tires without any special locker. Often aftermarket wheels allow the tires to creep under extreme torques and sometimes damage the tire or the rim.

That's quite a story about the tire unseating and going off like a shot gun. 100 psi seems excessive to me at least based on any of the vehicles I've owned. I read a lot of horror stories about different tire shops doing this stuff wrong and causing real damage. I'm thinking the installers are more prone to human error than a tire and rim is likely to fail on it's own. Based on other's experience with the Yokohama tires, I'm guessing the Discount Tire memo is an indicator of their inconsistent abilities across all their stores and not an indication of the tire's quality.
