fuzion 245/45 or 245/50 16
 

Which ones are more correct to run in the rear?

245 45

225/50/16 (front)
245/45/16 (rear)

is the correct size, i have them on now, they're good cheap street tires

id def buy them again

if you put on 245/40/16 the wheel diameter would be too small, and you'd get a higher speed reading then correct

total tire diameter for 245/45/16 = 24.681

total tire diameter for 245/40/16 = 23.717

Cool. Thanks!

245/45 is the correct rear tire size...btw i have one for sale
