245 vs 265 fronts

Apoc370z · 12-10-2013, 05:32 PM

Is the any benefit to a wider front tire? comparing the 245 stock size and the recommended 265 by a lot of people?

only thing i can think of is better grip but wider/heavier front tires = under steer?

can anyone shed some light on this?

I am running a 255/305 setup right now. I will probably be going 265 on my next set of fronts though. Would love to hear from someone who has ran both.

i'm running 265/285 RE-11's right now. i'd probably go 285 up front with a square setup. 245 is too small. not enough grip.

likewise, i just ordered a set of 245, now i am not sure i should change it to 265 instead. Anything wrong with the 255? i know your car has the power to support wider tires for sure

i dont know if i will ever go that high on the front, but 265 would be my max as a DD

You will obviously add a little more weight but it will look better and corner a little better I bet IMO. Are you running 285s in the rear?

The Z is lacking front grip big time. 265 is fine (I have a set of 265/285 front/rear waiting for spring) and will not increase understeer... in fact, it will help to decrease it.

I went with 265 front and 305 rears....there is more grip which makes it seem like there is less under steer. I know there are some running 275 up front, but that seems a little extreme. I was contemplating going smaller in the back to square it up a little more, but I think being turbo charged, moe back tire, moe better!!! Also that combo looks sweet on the car.

You will definitely want those 305s in the rear!

275/305
Go big or go home!

The smaller the difference between your front and rear tire widths, the less your car will understeer.

TerribleONE · 12-11-2013, 02:39 AM

You guys running 275s, how much camber? Do you rub?
