Currently have 235/40/18 all round, running 8.5" wide front and 9.5" wide rear. Looking at getting some more grip down and was thinking of putting 255/35/18 on the front but was seeing if anyone else had done this using the same rim width and if there was any bulge creating more of a disadvantage then an advantage etc? If I can run the 255 on the front I'll go 275/35/18 on the rear. If not I'll just stick with the 235/40/18 on the front and upgrade the rear to 255/35/18.
Any opinion/experiences would be appreciated!
