About to replace my rear tires on my '04 6MT Coupe with OEM 18's, and looking at the Michelin Pilot Sport PS2, as I would like to switch to these on all four corners when my fronts wear out. Any issue with putting PS2's on the rear and running the PS's on the fronts? Fronts have at least 5/32 left.

 

JMO, but I'd run off another set of PS then get PS2s on all four.
You can get some pretty weird handling by mixing.

 

Thanks for the feedback. Yes, this probably makes the most sense, given the wear rate of 2:1 rears to fronts. Discount Tire folks agree as well. Pilot Sports it is.

 

if you have tpms, it could throw it off... i would do as others suggested so u get the PS2 on all fours... I had nittos on my rears with michilens PS in the fronts and i didnt have a problem but it was only for 2 weeks.
