Got no dog in this hunt, what with our several-year-old and problem-free Duravis tires.
That said, and if it were me... That LTX/2 is looking good. It's from the world's premier tire maker. Still there are spotty complaints about LTX and it's a price-pointed OEM tire. On the other hand the XPS series enjoys a near-perfect resume and seems to be a much better long-term product.
If I could put the pennies together, I'd pay to upgrade to XPS series.
And I'd pony up for custom stems Tire-Man or Borg while I was doing it.
Buy a matching spare! Rotate Spare with the two Front Tires.
For $few100 you go from OEM to Gold Standard. Whale of a Deal!
