i think i'm gonna get the BF Goodrich G-Force T/A KDW, but still confused about sizing.

03MustangGT: why use a shorter tire in the rear?

nickthegenius: i've heard of using a skinier tire in the front to avoid "grabbing" the road with the front tires. do you have any problems with your car pulling into ruts in the road?

i'm thingking of
265/35/18 for the front
275/40/18 for the rear

is it a good idea to go to a shorter tire in the front and will the wheel to fender gap be larger or smaller because of this. thanks for the input.

by the way, the factory '00 cobra r uses the 18X9.5 wheel with 265/40/18 all around

thanks agin for the help

thanks wade, are you saying i should run the same size tire all around, or 285 in the rear and 275 in the front?

Yeah dude, wade nailed it. The reason I'd go with 245/40/18 front and 275/35/18 rear is because they are the exact diameter as the stock 245/45/17, which means the speedometer won't have to be recalibrated. If you went 265/35/18 all around, your speedo would be off by a little less than 1 mph. You would actually be going a little slower than your speedo is reading. Do a search on this, I can't remember where I found it, but somebody posted a link where you can type in the tire size you want vs the stock tire size, and the difference in speed as read by your speedo as well as wheel rotations per minute will be calculated.
