I have tried different brands over the 10 years I have had my 6.9, but I come back to Michelin in 14s. I have X-ones on my bundts. I don't think they make that particular tire anymore. Long-wearing and straight-tracking they are. I had some uni-directional tires once and they seemed to pull to the right. Why that is I don't know, but it happened. A change back to omnidirectional solved it. It doesn't make sense. But that's how it was for me.

I bought a set of bundts with some cheapie tires that had a proper fit, but not a proper weight rating and they all failed with belt separations. Two tires failed in Wyoming while I was returning to Houston.

this was a bad thing. the belts separate and the insides try to come out forming a bulge. They make the car ride like you have a brick glued to the sidewall, the balance is so far off.
