Front tire size suggestions for Stock V2 Nismo wheels on track
 

Anyone running stock V2 Nismo wheels on track? I ran with the stock 245/40 285/35 setup last year and there was some understeer. I want to get a wider front for the stock wheel. Thinking 255/40 or 275/35. I'm still a novice and don't want to tip the scale too much the other way.

I know there are many treads discussing tire sizes, but most end up being on 18" wheels. Couldn't find one specific to my query. If you do, that would be a great help too.

9.5" wide rim. Go with the 275/35-19 tire.

Yep, that's what I used, car will still have a tend to understeer though.

I'm running 265/35 on front Nismo wheel (V1 specs are the same) with 285/35's out back. stock suspension minus the Kino sports and the hotchkis front bar at full stiff. I don't find it overly pushy, yes i some scenarios like the hairpin at my local track (turn 10 NCM), otherwise feels pretty neutral. With stock lack of camber I hesitated to go any wider on the 9.5" I had pretty bad shoulder wear on 275's on a 9" wide wheel on my 350Z. so unless you have camber arms you may want to avoid squeezing the widest tire possible.

I have 285/35-19 on 9.5 theon front now. Think my next move will be 325/30-19 on 11's on the front to match my rear 345/30-19's. :driving:

Any issues with running 275s on a 9.5"? They are at the max recommended width for 9.5", so I was a little skeptical on going that wide.

Yeah, my concern exactly. I might end up going with the 265s

No problem running the 275's on the 9.5". I have 285's on 9.5 now.

I ran 285's on 9" fronts on my 350Z, they fit, but they are squeezed and in my case stock suspension means no camber and the outside shoulders wore badly.
