I ran an R32 GTR for 3 years as a daily driver, doing about 30,000km's per year. That included quite a lot of freeway driving and I never saw any issues in the driveline.
I had the same widths you have 9" front with a 235 and 10" rear with 255. It started because they were the tires that came with the rims.
I found the torque split to the front wheels happened a lot faster, making the car much easier to catch when the tail started kicking out. Plus making it better off the line, and just more traction every where. I did get some understeer, but I was replacing 235 all round so it was the same understeer I had before.
I used to have to replace tires once a year - Lack of rubber meant rotation wasn't much use.
The only advice I could get on the subject was all bad as well. "You'll destroy your transfer case" "no one else does it, so it must be bad"
So I'm really interested to hear someone else actually doing it and if there are any real world problems with setting it up this way. Or if it is just technical on paper behaviour and stats on wear rates, because I honestly never had any issues.
That's not to say my case was a fluke and I am totally wrong. Maybe I can be proven wrong, I certainly don't have an axe to grind on the subject and was recently thinking about buying another 32.
