The EP500/600 have the same listed treadwear rating, but the tread depth is lower on the 500 IIRC. Having autocrossed both, I would be surprised if they're actually the same compound, because they don't act like it. The 600 is going to last longer on the street. As far as changing wheels goes, one jack, one jackpad.
Thanked: 132 Times. Re: Bridgestone Turanza - Very trust worthy! Completed 70k on my Swift Zdi with 195/60 R15 Turanza ER60. I guess they will do another 5k comfortably, but planning to change them in next few days. As per my tyre guy, AR20's have been discontinued and ER60's relaunched and available for 4900/- per tyre.
