it's been 3 years now, only reason the fronts wore faster than the rears is a few parts wore down because of using EOC and hitting a speed bump at between 40 and 50 mph, not wanting to slow down. i kept them aired to 50. here's the miles i put on them:
they have an 80,000 mile wear rating so i think my money was well spent.
rears would still pass inspection so will be keeping them a little longer.
gathering parts to get the front back in shape.
CS4 has been replaced by Cooper CS5 Grand Touring 195/65R15 91T. cost is less than $70.00 each and wear rating is still 80,000. think i read that they are quieter. they helped me get a 59.6 lifetime mpg with 2 years since i started the fuel log.
