What's the worst case scenario for running the same size tire all around?
I know that the stock Z setup has a staggered set up 235 50 17 in the rear and 225 50 17 up front, and with varying degrees for the 18 inch and 19 inch stock wheel versions. Will I do damage to the car running 245 45 17 all around?

Sport Compact Car ran the same size tire on all 4 corners on an 18x9.5 rim. I think they were 265/45/18 at all four corners and that helped them achieve over 1g handling. I plan on running 245/45wr17 on my stock Enthusiast rims and dont have any worries.....i think you would be fine other than it messing with VDC if you have it..........

When this was last asked on several boards, the consensus was that the VDC didn't like it, and neither did the TCS. However - the results were not the same for everyone; some reported big issues, others said no problems. There is some risk, no question. But I don't really think that your car will stall on the freeway because of it......
BTW, the Sport Compact Car article stated their didn't have VDC, and it would have been no problem for them to turn off the TCS during their limited testing. The article was about getting 1.0 g on the skidpad, not about real world driveability.

At worst you will need to turn off VDC because it will apply brakes for you going around corners slow thinking your slipping-I have experienced this and it sucks, its so obtrusive it can actually take you out of your line. So if you can live with driving with VDC off, then go for it.

You are correct, I forgot about that. I ALWAYS drive with TCS off so I shouldn't have any problems but I guess with VDC and TCS it could play a factor in messing with those two.
I understand why it would mess with VDC but I don't really understand why it would mess with TCS? Can someone explain just so I know for future reference?
Thanks...

I am running 35 series on 19's all around...
why it would mess with TCS?
Now lets say you have put four equal size tires on, in that same straight line, all four hubs are turning the same speed. The faster you go, the computer still expects to see a growing difference but it does not. This is why high speeds can cause SLIP to come on solid. The computer thinks the back are slipping because they are going faster than they should compared to the front tires.
In cornering, the inside tires spin slower than the outside tires because of the greater distance they travel in the same corner, so if the computer is comparing the inside front to the outside rear, it would see an even great difference and that might cause the SLIP to come on at lower speed than it would in a straight line.

guys you're blowing this out of proportion
i have performance winters on my Z right now, same size all around... when the weather was nicer up here and the roads were dry, I was driving at close to 100 mph on the freeway with no problems at all (w rated winters)... this is WITH VDC ON and NO SLIP whatsoever
VDC needs a whole lot more than 1 or 2 extra revolutions every 10 seconds to detect a loss of control situation under street driving conditions
but if the poster is only interested in daily drivability and plans on turning VDC off @ the track, then there's no problem whatsoever imo

I've had the occasional slip light come on at 40mph as mentioned above. But at the time I was running 245 45 17 in the rear and 225 50 17 in the front.
Has anyone else running same size tire all around had that stall at 70mph that was mentioned?
I'd like to be able to rotate my tires, that's pretty much why I asked.
Thanks
