Weight distribution is different, but down force equates to weight. The tar wear should be similar.
That said, some teams ran three sets of rights to one left with all the wear being on the right side. I’m sure the Indy cars are using all four to hold the track, not just the right sides.
One of the discussions said the drivers at the test thought the ones GY brought were too hard and they wanted softer. Wonder if they changed compounds without even testing?
” I’m sure the Indy cars are using all four to hold the track, not just the right sides.”
Not sure but looking at Indy cars I could see how that wing helps them turn. The Cup car has more inertia. Down force puts the indy cars tight to the track, the cup cars are designed to slide. It is the sliding (across the cuts) that kills the tars. Try it with a bastard file: going with the grain you can push as hard as you want and no problem; even light pressure across the file rips the skin.
I’m not defending Goodyear in general, but this track is wrong for Cup cars.
