I had a couple of Viva 2s a while back on a Camry, and they looked good but were lumpy.
When I need a couple of whitewall tires in my size for the Lincoln, I found that whitewalls aren't as easy to get as they used to be, at least not locally and for cheap. I reluctantly bought 2 more Viva 2s, telling myself if they were lumpy like the first ones I had previously I'd have Wal-Mart rectify the situation one way or the other (as I should have the first time.)
Happily, the Viva 2s on the Lincoln are as smooth as silk at all speeds, though they weren't even close on the balance at the time of initial installation. Second time was the charm.
