I am at almost 21k now and will do 1 last rotation and they are done so I predict about 23-24k total. Dont freak out when you see them initially wear very fast because the second layer is a harder compound and will last much much longer then the first layer which was the softest.
If you dont drive like a **** head the car wont break and your tires will last, amazing isnt it. LOL. You race track a $23k car which by racing standards is cheap as hell then things start to break hence all the complaints some have and the negatives things said about the very same car I have which runs perfectly. I sort of treat this car as it is fun to drive fast here and there but dont try and launch it or get the bet 0-60 on weekends. I imagine if you did things all go south very fast.
Call me old or responsible but at 29 the car thing doesnt seem as fun as it used to be when I was 21. CAI and I am dont modding it and wait 3 years for another new toy.
