The 255/35/19s come in at 29lbs while the 285 are at 30 lbs.

PS2s come in at 25lbs and 26lbs, the OEM weights for a 19" PS2 245/35/19 and 265/35/19 are 24lbs and 25lbs. With the SO4s you are adding 20lbs of rotational mass. Yes you are adding width to the tire but a lot of weight as well. I would try to get the width without adding much to rotational mass.

The Invos come in at 25.5lbs and 27lbs for the 255/285 setup.

I've been contemplating the weight factor of Bridgestone SO4s considering these tires are heavier than the stock tires, independent of brand, that accompany the Competition Package ZCP wheels. However, when compared to the Pirelli PZero Corsa System installed on the GTS with weights of 25lbs front and 29lbs rear, the weight specifically for rear is more inline with 255/35/19 & 285/30/19 setup. I can't believe the front tires are 4lbs heavier at each corner than any other brand of OEM tires in the ZCP or GTS configuration. Is it possible this information is incorrect on the Tire Rack site?

Ideally, the best of all worlds would be the PSS in the GTS setup because Michelin always seems to make light weight tires in addition to their high performance standards, but as KennyPowers states it's about compromises. What is the right compromise? Which is the question that has me at the crossroads and I'm so desperately trying to make a decision.

Dave et al.... If you had to decide between the PSS in 255/35/19 & 275/35/19 or the S04 in 255/35/19 & 285/30/19. Which setup would you run on Morr VS8.2 wheels and why?

Additionally, Tire Rack also list the Continental ContiSportContact 5P in the M3 GTS 255/35/19 & 285/30/19 configuration, but the websiet doesn't site any testing of this tire. Does anyone know how it compares to the Michelin PSS or Bridgestone SO4? Ben?

You are right, Tireracks info is wrong...they are heavier. Bridgestone shows the rears at 31lbs for the 285/30/19 the front 255/35/19 is shown at 29lbs.

Here's the site..http://www.bridgestonetire.com/produ..._Pole_Position

You know I'm not a fan of a 275/35/19, I think its to tall. The 285/30/19 looks so much better IMHO and on a 10" wide wheel a 285 fits perfect. The new ContiSport 5s seem to be a good tire. Someone posted up a while back who is running this setup and he really liked them.

If I was to choose though between the PSS at 275/35/19 or the SO4s with the 285s...I don't know that would be a toss up for me. The SO4s really add to the harshness of the suspension but I like the sizing, but I think the pSS are a better all around tire.

BTW, you didn't say what the tire will be used for. Are you doing any DE's? Mainly street than I would go with the ContisDWs or the Nitto Invos or go with the Pirelli Pzeros that are OEM now on the M3 and they only weigh 23lbs and 26lbs for the Mercedes version of these tires. Also the Yoko Advans are a good tire as well.

Dave... the new tires would be mainly for daily driving and an occassional DE. My M3 is presenlty configured with Pirelli PZeros as they are the OEM tires delivered with the car. I was looking to do a different tire setup with the Morr VS8.2. I want a tire in the GTS configuration that has high performance standards and is a good all around tire like the Michelin PSS.

I believe I could get over the harshness and weight issue of the SO4s, if they have excellent dry and wet traction and cornering stability. However, the S04s do not perform well, the I would go with Michelin PSS, especially with all of the good press about them. Even Andy at Morr, recommended the PSS over the S04 with their respective different configurations of 275 vs 285. Although, he did mention when he ran the S04s it was on a 20" wheel and suggested I factor that in when making my decision.

Would you chose the ContiSportContact 5P over the Bridgestone S04s?

How about a set of Pirellis in the GTS sizes. The PZeros that come on the M3 now are an excellent tire and in line with the PS2 and possibly even the PSS. Between the ContiSport 5P or the Bridgestones I would take the 5Ps.

I think he meant 285/35/19. There is no 285/30/19 for AD08.

Sorry, the beer must've been flowing too well from the tap when I posted. I'm actually running 275/30 19 rears.

Anyone know why BMW decides to run a lower sidewall for the rear? 30 compare to the front 35.

ALSO why isn't anyone running Toyo T1R, they come in 285/30/19 sizing with very good reviews

if run 35 rear..u will rub...

What kind of miles are you getting with the factory Pirelli P-Zero 265/35/19 on your M3?

I think these tires wear quickly and are not a good value, comments?


Thanks

[LarThaL]

I've gone over all this tire stuff a million times, backwards and forwards. Rubbing vs. no rubbing. Weight, ride comfort, spacers vs. no spacers, etc, etc, etc. I came to the conclusion that the best solution to balance grip, weight, ride comfort, proper stagger.....everything, was to go to an 18" wheel and get 265/35/18 and 285/35/18. I do love my ZCP wheels and if there were a good selection of tires that came in 245/35/19 and 285/30/19, I would buy them and keep my ZCP wheels, but there just doesn't seem to be.

[slicer]

I think the best option for ZCP wheels is 255/35, 275/35. 285/30 increases the width stagger front to rear which is not a plus for handling. It's also a smaller diameter from the rear which is not consistent with BMW's design. The GTS may have those sizes but it was designed to have them. I'm sure that BMW made adjustments to the suspension and DSC for the change.

[spr]

They also make 255/30 and 275/30 in PSS to keep diameter ratios the same. I think I may do this. s04's are not available in the GTS sizes btw nor are t1r's per tirerack's website. WHY DOESN"T MICHELIN MAKE A 285/30/19!!! GRR.

They do in fact make the S04 in GTS sizes.
