I remember when all season tires became available. I put them on my car 10 or 15 years before they were common place or popular. Back when they were an expensive upgrade over a highway tire. Wow was I impressed. Now most car tires are all season.
I remember when studless Winter rated tires for year round use first became widely available. I now run these on my Buick and use them like an AT (since no AT are made in size for my car).
Look how far we've come since the days of HT vs MT. Now we have AS, AT, radial MT, and hybrid tires.
Now there are so many choices of AT that people can ask which AT, and argue about which AT, or which AS, or which radial MT, etc.
Warning: Sometimes I edit a post a few times to get it how I want it.
