+1, It's virtually impossible (maybe actually impossible, but I leave the possibility open) to wear out a front tire. In well over 100k riding over 4+ decades I've never worn a front through, and that includes tens of thousands of miles on light tubulars which don't start out with much. Not only have I never worn out a front, I don't know anybody who has.
I did come close recently, with the front tire of my commuter. After maybe 15,000 miles it looked like I was going to have a first, and I kept it on even though it was so ratty that I normally would chucked it. Of course it blew apart before that last .01mm of tread wore through. Close but still no cigar.
