Need to replace the rears only and have come to the realization that Michelin no longer makes the PS2's in my exact size: 285/30/18 for my 18" carrera 5 spoke 10" wide wheels.

I really don't want to buy 4 new tires as my front tires are in great shape. Would any of the following PS2 sizes work for my rear rims?

275/35/18
295/30/18
295/35/18

any trade off to putting a different size than the OEM size?

Just make sure are within the 3% maximum deviation.

The 275/35 would be 3.3% which equates to 28 revs per mile (not good)
The 295/30 would be less than 1% (very good replacement if you have widen than a 10" rim)
The 295/35 is over 5% and your worst choice.

If you have the 10" rim go with either a 275/30 which is less than 1% or the 265/35 which is just over 2%.

Remember, 265/35 was the OEM size from 99-01 for the 18x10 rim. I have since moved from that to the 285/30 on my rims.

so the 295/30 will not fit on the 18x10 rear rim??? they unfotunately don't make the PS2 in 275/30

Don't hold me to it, but if I am not mistaken you need the 11" rim for that tire. It can probably fit but you will bill on the max limit. Why not get the PS Rib?

I have the PS2's on the front with loads of tread left. I have been warned against mixing & matching different tires even though they may be their "successors"

on the last atlanta drive, one of the ferrari 328's had pilot sport a/s. he said the performance was identical to the PS2's but they had a longer tread wear life. anybody ever heard of putting a/s on a 911???

they make a pilot sport a/s in 285/35/18 but then I'd have to get new fronts as well

As long as you don't have the C4 or C4S you will be fine in a 2WD. If I am not mistaken, the tread pattern is very similar b/t the PS2 and the PSRib.

am i correct in remembering though that some have tried the PS Ribs and NOT liked them for some reason or another?? i seem to recall this.....

LVDell

HMMMM, can't comment on that. I have only have the SO2 and Conti's.

Lizard1

problem solved - thanks for the help!

I think more people actually liked the PS Ribs better then the PS2. Just went through this decision process last fall. The main difference aside from tread pattern is the sidewall stiffness. I went for the PS2.

Why not on a C4? I was thinking seriously of replacing mine with new tires, and would like to go to the 285/30 on the rear and 225 in front? Forgive my stupidity if that is a lame *** question...
