Yes Sir, 4 matched tires . I had stock size highway tires , Now, I have slightly oversized off-road tires . I get the same result with either set off tires . Full lock around 100mph . I've done multiple pulls up to 100 and let off , then accelerated again back up , and every time it switches to an even split at around 100. I'm not sure exactly what speed it happens at, but I do know that it's north of 95mph.
