ADVICE NEEDED re; 245/40 versus 235/40

[07MPS6]

Hi Guys,

Since getting my rear arches rolled and fractionally pulled I reckon I can now easily get 245 x 40 tyres (on the rear only) to replace the 235 x 40 that I am currently running.

My question is this, will the very slight difference in overall diameter between front and rear wheels affect the AWD system in anyway at all, I know that you cannot run staggered fitments on an Impreza because it will wreck the centre diff, however you can run staggered on a Skyline with no problems at all.

If it helps these are the figures.

235 x 40 x 18 has an overall diameter of 25.4" or 645mm
245 x 40 x 18 has an overall diameter of 25.7" or 653mm

This equates to an 8mm overall difference OR only 1.24%

Any help/advice would be much appreciated

get the 245's mate. i havr 245's on all four corners of my ms6 and it handles so good

yeah some skylines are RWD only. thats the reason they can run staggered fitments. any kind of differences in tire size can effect the ride. i had a cracked rim and put 2 stockers on the front end of the car and my 4WD light was flashing after about 10 min of driving.

Im running 245/40s as well with my RX8 wheels on my ms6 with no problems and love them.
