Threadwear?

Noite Escura

The unpredictable
I recently changed 2 Continental tires to Goodyear ones. I noticed the new have stamped "Threadwear: 240, Temperature A", while the old tires had Threadwear: 280. Is this a good thing or no. Did anyone knows what Threadwear stands for?

I'm sure things are different under Brazilian law than US law, but in the US it's "treadwear" and the number is how long the tire lasts before it wears out compared to the "index" tire with a rating of 100. A typical all-season tire sold in the US will have a rating of 400-450, whereas a performance tire will often have a rating of 200 or less. That means the all-season tire would last twice as long as the performance tire and four times as long as the "reference" tire.

I don't know what the reference tire is rated at in Brazil, but generally you can expect your Goodyears to last a few thousand km less than your old Continentals would have, but not really a whole lot less.

Ok, it's treadwear, I got it from memory. They said the Goodyear should last 60.000 km, which means the Conti should do 70.000. That is surely overrated as they were almost 'slick'' by 45.000...

It also depends on driving conditions. For example, how often do you check the air pressure? How often do you peel out? Is your car kept in proper alignment?
