Feedback on P85+ with all four tires @ 245/35R21 ?

yea. drop down to 19s. you'll quadruple to octuple your tire life.

I'm considering swapping out my rear wheels/tires (265/25R21) on my P85+ with the same size as the front, (245/35R21).

That way I could use the much cheaper, and better Michelin Pilot Super Sport tires. They are rated better in wear life, handling, braking, and comfort compared to the Pilot Sport PS2s I'm using now.

Has anyone done this? Thoughts?

I'm currently in the midst of this experiment. I got 12K on my PS2s in the rear--the fronts are still at 7/32 after 19.5K. I put on the new PSS in 245/35 in the rear. After 7.5K miles, I'm at 7/32. 6 thousand of those miles were from a road trip, so not a lot of stop and go. I've found the performance fairly comparable. It's not super economical to rotate because the rims are different widths and swapping rubber can run $50/tire last place I went. I thought if I were unhappy, I'd push the PSS tires up front and get back in a stagger with a wider PSS--can't remember the exact fitment, but the diameter is very close. It was a 30 series--either 265 or 275, most likely.

I have the PSS on my rear and front and they have 28k miles and 5/32 still left.

I have no regrets. I haven't measured the tread depth.

Those of you that are doing this, did you mount the 245/35 tires on the wider P85+ rear wheels (9.0" I believe), or did you get wheels that match the front (8.5" I believe)?

On the original wider wheels.
