i just bought new tires for 6mt coupe: Goodyear eagle f1 245/45/18 96W and i went to take a look at my car tires i realized its using 245/45/18 100Y.will 96w and 100y will make a big difference on the load and speed? please reason it, im noob at this.

 

No difference at all.

They both cover the max speed of the car. Google "Tire Speed Ratings" for more info.

 

+1 no difference

 

yep no diff
