id prolly stick with 295/30/20 in the raer, 25 will be too small...

I doubt you could fit a 295/30/20. 285/30/20 is already 1/2" taller than OEM. 295/25/20 or 305/25/20 are common sizes for 20" wheels. The 305/25/20 would have to be a tire that does not have squared shoulders to fit on a lowered car.

The 265/30/20 in the front is the bigger issue. Again 255/30/20 is a common size and even that is tight on certain tires. 265/30/20 might be pushing it but I don't know if anyone has ever tried it. I'd like to know myself since I have the same dilemma.

this is driving me nuts

got the new PSS on my car for about a month or so, the tires just don't feel right....the ps2 were great, so i expected this to be better overall...

F 255/35/18, R 275/35/18 does this size look okay?

What about them doesn't feel right? Were the PS2's you had before the stock size?

when i had the ps2(stock 18), i was confident going fast thru corners/ramps cuz the car felt like it was glued to the ground....

with the PSS, i dont get that feeling at all!

It can take 500 or so miles for tires to come into their own as the release agent used to release them from the mold can permeate the rubber. Also, fresh rubber with all that tread will experience "tread wiggle". When a tire wears the tread starts to wear down decreasing tread wiggle increasing the tires turn in response and stability. There is a reason why racers shave tires down.

How many miles have you put on them so far? It might take a while for the tires' grip to come to its optimum point.
I've had my new PSS on my car for about a month now and they feel great! Though I haven't been driving very aggressively too often yet since putting them on.

I am running the same size as you and absolutely love the PSS over the PS2.

How many miles so far? They do need a few hundred miles to wear off the mold compound.

Moving from used tires to new tires can also have an effect, as the car is a bit more squirely on the taller thread blocks.

[richardbb85]

probably around 1500 miles already, very disappointed so far

So are they just lacking in traction, or more of a unstableness or squirmyness due to sidewall flex?

[Dodge2Dub]

Honestly, I have been extremely happy with my set. Turn in is better, traction is better and they seem to be holding up to aggressive canyon driving. My set has been a marked improvement from my previous PS2's.

Richard, you may want to talk with Michelin or the store that you bought the tires from because you should feel an immediate difference after 500 - 1,000 miles.

I have 265/35/18 & 285/35/18 on Eibachs & don't have an issue.

What wheels & offset?

I thought I was the only one! I've had my PSS on since mid march, about five thousand mile ago. And at 62K miles I have had two sets of PS2s and a winter set of Conti's DWS all seasons. These PSS lack the grip of the PS2s and does seem to break lose al lot easier than PS2s ever did. To me it seems to perform only on par of my Contis. I know about the release compound the he need for it to wear off, but after 5K miles there seems to be no appreciable difference since day one!

The Pilot Super Sport tire manufacturing facilities do not use mold release agents and all molds are either bare or coated with an industrial coating/not lubricant. This coating reduces friction, improves wear resistance and is used for non-stick applications. An example would be non-stick cookware (like DuPont's trademarked Teflon). All of the Pilot Super Sport molds (both in EU and the US) have these coated molds.

The PSS's have been shown to have better handling, braking, and wet performance than the PS2. They are a summer tires, has it been colder than normal in your area since you got them? Where your PS2's run-flats?

Your sizes seem off....by a good amount!!

Most people are running 255/35/19 and 275/35/19.

If you are going wih 18's, this would convert to 255/40/18 and 275/40/18

Better sizes on 18's would be 265/35 and 285/35.

I too thought it was me but I hate the feel of the PSS's- PS's were FAR superior to me- original size- I do not get it.

I have also noticed the same thing compared to the BMW PS2. I have PSS on the rear in oem dimensions, with BMW PS2s on the front. I am aware that it isn't advisable to mix the PSS and PS2 but I'm not prepared to waste a perfectly good set of front tyres, and I personally do not feel that there is an issue of safety unless the car is being pushed to its limits - I have separate wheels for performance use.

Back on topic, with PSS on the rears, the car's steering has been blunted and quick direction changes, especially at higher speeds, occurs a fraction of a second slower than steering input, with the car taking a bit longer to level out. This is due to the fact that the PSS has a significantly softer side wall than the BMW homologated PS2. My fix: raise the pressure appropriately.

This is not to say that the PSS is inferior, but rather that the tyres that came with the car from factory are custom made for the M3, therefore, will have certain characteristics that off-the-shelf tyres, of the same brand and model, will not.
