since Dan's too skeered.... I will HAPPILY speculate

Based on my own usage of the same tires... i would imagine probably 6-8 weekends of time left for an intermediate level driver.. .. assuming 4 - 30 minute sessions a day and two days per weekend. if the owner were to pay to flip the tires on the rim(s) after the first 4-5 weekends, they could likely last even longer. Dan is definitely correct... tire wear is greatly user dependent. Also.. what one feels acceptable to drive with regarding wear bears and low tread is also a personal decision.
