Tire Recommendation Needed

Obligatory Photo:


I recently got a set of Michelin Pilot Super Sports. My expectations were very high when I put these on. So, of course, I think these are amazing tires. Steering response is better, car has better road feel with better high-speed stability. Most impressively, these have DEATH-GRIP in dry as well as in dry.

I run an OEM staggered 18" setup with non-sports suspension. I WILL have coil-vers done soon, but I find these to have a rougher ride that I expected, especially on uneven surfaces. I know it's suppose to be improved road feel, but I feel like this is unnecessary jitters and vibrations that are coming through. Hard bumps and pot holes make me feel like I don't have any shocks under there. Also, though some people say these are quiet tires, I find these are louder on anything but super smooth surfaces. I think the stock Bridgestone's are way quieter. Then, there is too much grip for my taste. The car understeer like a font-wheel-drive car with these. I know this helps with high-speed stability, but cornering is less fun.

Can anyone recommend me a tire that is in this level of performance, but do better on above short comings?

I'm confused... You said there's a lot of grip and then lots of understeer? :S

If you have lots of grip up front there should be less understeer. What's the stagger difference between your front and rear tires? Understeer is bound to happen on rwd cars when the grip in the rear is far greater than up front.

Also have you gotten an alignment done lately?

Yea, I understand your confusion.

I have OEM 162's. 225 up front and 255 in the back. With stock tires, car was neutral to me. With PSS's I think there is too much grip in the back. Car leans and sways too much and promote understeer just like any FWD car back in the day.

My alignment is up to spec, done after tires were put on.

I think I need coil-overs with a stiffer rear sway bar in the back.

New suspension will likely help. Honestly though, for the price I don't know if you'll really find anything that's much of an improvement over the PSS. I'm kind of surprised that you would like to switch them out for something else.

Something doesn't sound right about your corner issues.


Regarding comfort, did you go from OEM run flats to PS run flats or standard?

pss is one of the best tires you can get out there before you start getting into things which are more street/track.
suggestions would be to upgrade your suspension like you mentioned or upgrade the front tires to something like 235s. also might look into running a bit more camber up front. the harsh ride might be due to higher tire pressure. what psi are you at?

also, if harsher ride is bothering you, might not be in your best interest to go coilovers

I run 36 front and 42 back PSI.

I want to get coilovers but want to stay near sports suspension height.

You need to check your pressure against the PSS arrows on the sidewall to properly determine the pressure for your car. Place a white wax mark next to the arrow, go for a drive and see if need to reduce or increase the pressure.

This is the first step. It is a very important step to ensure best handling and ride with the tire.

It is a small arrow.

seems like you just want to improve handling without lowering, i would start with things like the sway bars and bushings

Hmmm... can you elaborate on this technique, please? I have a set of PSS coming for my 2008 328i (with sport suspension), and I've never heard of checking tire pressure in this fashion.

Thanks.

Cheers!

I've never heard of this before. How will you determine if you should increase or decrease your pressure?

Basically, you draw a line through where the thread pattern ends and where the side wall begins (most tires are marked for with a triangle) with a chalk. You go drive around normally and check where the chalk has been faded. If the fade is towards the sidewall, pressure is too low, if the fade is towards the thread pattern, tire pressure is too high.

There is a write-up on this board for this somewhere.

My question is: PSS's don't have a triangle mark?

Hi Gary,

The PSS has a little arrow on the sidewall pointing with the tip pointing towards the tread. I never heard of this either. Learned about it from a fellow on this board.

Truthfully I learn lots of stuff about my car on this board and I loved this trick for the PSS because once I got it good, they are really good and I wrote it down.

Hmm, that's interesting. Never heard of this method before, but that's something I'd check out/consider.

Michelin is not answering my email. Could anyone confirm the arrow on PSS's?

I just got my brand new set of PSS tires today, and I went over the sidewalls with a fine toothed comb. No sign of an arrow. The closest thing I could see to that would be the Michelin Man pointing to the tread line:

Really? Got pics of the small guys? I can't see them on my tires.

I got the pic off from somewhere else online, but those little Michelin Men marks are all around the tire. Wonder if they mean anything. Wish someone can take a better pic...
