R32 Gtr Tyres

[ryan.gtr.250]

On a r32 gtr do u have to have the same size tyre profile all round or can it b different? Because i have 255/35r18 on the front and i just put 245/45r18 on the rear is that ok or dose it have to b the same all round? If not can i just leave it in rear wheel drive?

You should have the same size all round but those sizes have a pretty similar rolling diameters so you should be right.

Ok cool thank u and so that should b ok with the four wheel stearing?

I think it is more so the middle numbers...

The Aspect Ratio or also know as the Tyre Sidewall Size.

So your Aspect Ratios are out as the fronts are 55 and the rears are 45...

GTR's should run the same all round.

Since it's not out by much, you should be ok...

You have wider tyres on the front than on the rear. Which bozo came up with that idea? Asking for trouble, I feel.

The aspect ratios are 35 front, 45 rear. The problem you are likely to have is with ATTESSA (4WD), not with HICAS (4WS). The width / aspect will be ok as far as ATTESSA is concerned, but really....

Some people don't deserve to own a good car.

I ended up having 245/40/17 on the front and 245/45/17 on the rear at one stage(had to replace rear tyres due to punture).

Every bump I hit caused the front tyres to get drive. Now my ATTESSA needs a good bleed (have same size all round, works fine when it doesn't crap out).

Run the same size tyres all round. You will risk wearing the ATTESSA out. Note since your rear tyres will be spinning quicker than the front, I'm guessing the car will be sending torque to the front wheels a lot more than what I experienced.
