Why not 275's up front?

personally i went 265/305 for the matching F and R diameters.

if you get too far apart in diamters you can possibly have the traction control light come on due to the sizes being too far off (different speeds) the car thinks they're spinning.

I guess for the record and others who find this thread, I haven't encountered that yet. About 3k miles since I went with 275/35 F and 305/30 R (Potenza S-04). I went on the recommendations I saw around the forum as being a good choice.

oh yea i agree with those sizes you shouldnt have any issues. i believe those are 26.6" in the front and depending on which 305's S-04's you got they are 26" and 26.3"

i was making a point for future reference that others should keep it in mind when swaping sizes away from oem. also brand to brand sometimes run slightly different widths even though they are the same at 305 or whatever you choose.

i just know the 265/35/19 and 305/30/19 RE-11s i run are 26.3" diameter all four corners.
