I just got my MPSC's installed (nitrogen filled) and had an opportunity to try them out. They are BY FAR the best tires I have had on this baby. They blow away the PS2's...of course they are not meant for rain etc., but I don't drive in that stuff! I can't believe how they have transformed the handling of the car. Tom you were right! Thanks man!

 

What sizes did you mount? I was thinking about them as well. Can you fill us in on the benefits of nitrogen for inflation??

Nitrogen is a totally inert gas and does not expand or contract with temperature. The added bonus with Nitrogen is there is no moisture
in your tires.
Actually they just always use it so no big deal.

 

becareful if your using these on the streets!

not sure if the nitrogen is a good idea on the street as the cups take some heat to get them to optimum grip with just air.

they may feel great new, but as they cure and have a few heat cycles it will take some time to get them to heat up for optimum grip, if you aren't careful an heat them up they'll suddenly loose grip!

 

Thanks oak...I'll be careful I guess I'm just like a kid opening gifts on Xmas...all I can say is...awesome. They just feel so much more predictable than PS2s or Bridgestones.

 

hehe...I know how you feel! that enthusiasm can get you in trouble! ask me how I know..too many close calls. the cups can bit you in the *** on the streets if your not careful.

 

Still way better than the PS2s or SO2s IMHO!!!!!

 

predictable that's exactly right. just get used to the ice skating style rolling out of the neighborhood.

 

Congrats !!!what size wheel do you have , I am asking because for my 2001 TT i was told I could not fit 315 on....my track wheels are 18/11.5 in the rear...

 

HRE 8.5 front and 11 rear. 315 no problemo!

 

cool it has been so long now I can t remeber if I got 805 or 9's up front definatly 11.5 in the rear...

 

wross, glad to hear that!!! I have one set on the GT2 cup wheels which are 12's in the back!! My other set same size is like yours!! Love them!!

 

Actually Nitrogen expands and contracts with temperature just like any other gas. The only benefit is that it is dry.

 

and it cost a whopping 4 bucks so who cares!

Arling...the things rides on rails...cold!

Chris..Nitrogen is relatively inert.Contrary to some claims that nitrogen will diffuse more rapidly through rubber tires than air (and oxygen), nitrogen molecules are less likely to escape from the inside of a tire compared to the traditional air mixture used. Air consists mostly of nitrogen and oxygen. Nitrogen molecules are larger than oxygen molecules and therefore, all else being equal, larger molecules diffuse through porous substances slower than smaller molecules.

Tom, thanks again bud great advice...I love them!

 

man wross all the great stuff you have done to the car glad you are so excited about the tires!!!!
