Thanks for this info, Pad. We’ll see how my Angels hold up. I’ve run a few sets of PR4s (haven’t tried the 5s) yet and, initially, thought they were great. But, for me, they cupped something horrible, seemingly overnight, so that’s when I moved to the Angel GTs. But, like I said, I haven’t got enough miles on them yet so time will tell. But, so far, so good.Hi Tom!
You may not experience the same thing as I did, unless you have the same riding style as I do! The Angel GT is a dual-compound tire, just like all of the PR series and the new Road 5. The harder compound is in the center of the tire, while the softer (grippier) compound starts somewhere up away from the center. Getting slippage when leaned hard over means that I was 100% on the soft material of the Angel GT, and it isn't as good as the equivalent material of the PRs that I have had (PR2, PR3GT, PR4GT), or the Metzler Z8 that came from the factory on my '15 RT. There are other issues with the tire, and you should look at what I wrote in this recent thread, Post #22: https://www.bmwlt.com/forums/rt-series/185687-r1250rt-ready-new-tires.html
Initially, I thought that the Angel GT was going to be my all-time best tire, but that changed as the miles built up.
