are 265 s on front of r32 gtr to big?

[400kwgtr]

just got a r32 gtr which has 255/35/18s on it. was thinking about putting 265s on the back but am i going a bit overboard putting 265s on the front? i know they will fit but will the steering be heavier? should i just go for 245s on the front? cheers

you really should be keeping all 4 tyres the same size. if you want to go thinner then you would have to increase the profile of the tyre as the attessa computer will get stuffed readings due to the rolling diametre of the wheels being different. i have 265/35/18 on all 4 and i dont have any troubles with that.

cheers for that, i will go with the 265/35/18s .

you shouldnt have any problems with having differnt size tyres on your gtr, ive been driving with 286 rear and 265 fronts for almost 2 years now with no problems, casue the gtr isnt AWD it 4WD so the front only grip when the back slip which in most cases isnt offten uness you rev and dump and ive been doing that for ages with no worries.

[WLDCRD] - what size rims and offset are you running? have you rolled the guards / is there any scrubbing? cheers

As you say, the system isn't full time 4WD, however the ATTESSA computer compares the speed of the front and rear wheels and uses this information to decide if there is any slip present.

If you have different rolling diameters between front and rear axles, there will be a constant partial torque split to the front and hence a constant pressure in the transfer case.
