I had summit racing balance them, and they did a fantastic job , they ride super smooth and very nice, definitely has alittle noise to them. My last set was the venom power Terra hunters and they balanced bad and had vibration and only got 28k out of them. so far I like the new mutant but only have about 1k on them so far.How you liking these? Just found these when searching on Kaltires website, and love the look and the price. Seen a review on YouTube though with a guy who had these on an F150 and started to get a crazy vibration after having these on for a bit. Comments on that video as well that others Have had issues getting them balanced properly
