    How the fuck do the tires even pick up the road at that point 😂

    Driving on the free way?? Christ on a bike

      Cars on race tracks use bald tyres for more contact with the road, which gives better grip. The tread is there to guide water out so the car doesn’t slide in the wet.

      Unfortunately it looks like the image is of a car with bald tyres in the wet (I’m assuming that’s why it’s shiny).

        I think the car might have been parked overnight because it looks like there’s a layer of ice coating the tire. Talk about hard mode, now every street is an ice level!

        Also worth noting though that the main reason race cars are able to get more grip with slick tires is because the tires are made to have a very low melting (?) point. So they heat up very quickly and also don’t last very long as a result. But that heating up allows them to literally stick to the ground. Normal car tires ain’t doing that for sure.

          Man I just went down a rabbit hole and no one can agree on car tyres. It seems you’re right about special racing tyres that melt and attach to the road (after warm up laps), but no one can agree on whether bald car tyres in the dry have more grip than treaded ones (in ideal conditions). For sure, wet, snow, sand, gravel, etc. You want the tread, which is pretty much every public road since they are not swept perfectly clean and smooth. But I could not find an answer to whether bald tyres grip the road better. People say they don’t, which is why racing cars use slicks, but that’s not proof, even if bald tyres grip better they would still use soft tyres for even better grip.

          I found reddit threads with engineers saying one thing and other engineers saying they are wrong. Racing forums with non-engineers saying the soft slicks are the reason for grip and bald regular car tyres have less grip. No one can back up their claims.

          It’s obvious that it’s a bad idea to drive on bald tyres because the road is always an imperfect surface, but I can’t even find a hypothetical answer to the question with any confidence.

          Using f1 as an example (Because every series will use a different tyre) across the five different compounds used 100-110°c seems to be the range for optimal grip.

          If you could get a normal road tyre to that temp it would just fall apart.

      The knobs on tires are so that water has a way to escape when a car drives over it. A completely flat Tyre has the most traction but can’t handle rain. Every day Tires have a mix to handle all conditions. I may be wrong but I remember hearing this in a youtube video
