Tires are only part of the equation, other is road surface, our roads are in very poor condition, huge damage caused by the excessive use of road salt. And a government stealing our road tax dollars for whatever other uses. We could have gotten more mileage out of our Continentals, but one thing we didn't like about them is very poor winter road traction.
No tears were shed when we got rid of them, and consider our lives are far more important. Front tires will always wear out quicker even with careful driving with single wishbone suspension. Every time you hit a bump, plenty of those, camber varies, and worse yet get side scrubbing, tires can move in and out sideways by as much as 0.3 inches. Rotation equalizes that wear, but does not prevent it.
Being dumped on this planet earlier than most of the guys on this board, could bring up the subject of tube type tires. Major reason given was the tube would rub on the tire causing wear, if this was a problem, never was one of mine.
With tube type and a nail type flat, could remove the valve core, step on the side of the tire to break the bead, and with a couple of pry bars remove the tire, tube and patch it. Yes you always put a chalk mark on the tire by the valve stem to maintain balance.
This end with tubeless, has to be sealed to the rim with glue and takes a super powerful machine to break that bead, also stresses the hail out of the tire. On an 18" rim have darn near 10 feet of rim surface area that can leak and sure doesn't help with even more road salt. Never was a problem with tubes, is now.
Do remove the tubeless tire, should be soaped on both sides, both the upper and lower beads have to be broken, the rims and the beads of the tire have to be cleaned, and new sealant put on. Sure see guys take shortcuts in this respect.
First flat I had with tubeless, plugged it, that was a big mistake, hardly drive the car a couple of miles with a major blowout. That plug does more damage than good, since then, insisted on getting the tire removed and having a patch vulcanized on the inside.
Just saying, more problems with tubeless than with tubes from years of experience, and the government has a solution to this problem, make TPMS mandatory. With even a lot more expense to the consumer. Yet, another after the fact solution.
What happened to the full size spare? Ha, on cars like my 30 Olds and Ford, 33 Buick, and 37 Cadillac, had not one, but two full sized spare tires. Sure going backwards in this respect, and a spray can for a solution? You got to be kidding.
