Ok i have picked a brand Michelin PS2 for my already ordered HRE P40 rims 9x20 & 12x20, going on a Porsche 07 997tt,car will also be lowered ,now i need to make sure i have the correct tire size,is it 245 30 20 and 325 25 20 .Also does it matter if you get them from two different locations,i can get the fronts for $311.00 at my local Americas Tire but they don't carry the rears i found those online from discount wheel for
$473.00 each,thanks in advance for any help.What about the Pirelli Pzero's compared to the PS2's they are an even better price at Tire Rack,
use is going to be only on the street but i do want some great traction as i love the curves.

 

Great car and great choice of wheels. Take solme pics when you get a chance.

 

Sizing is correct. Give me a call if you would like to order!

Thanks.
