sorry guys scratch that, just called tire rack to order them ant to talk to someone who knows a lot about it and it seems those tires are worthless..
they may be 305 from sidewall to sidewall but the tread width/contact pach is less then that of a 285.
they were designed for domestic retardizm... basically only for looks with slim contact patch and big puffy round sidewall for a more aggresssive muscle car look.
now they are taller if u want they would be a great drag/dig launching trackion tire but if that's what ur looking for there are MUCH better options then this.

just go get 305 RE-11s :tiphat:

I'm going with the re-11 but not in 305, the 285/35/19 is better for what I'm looking for. I don't want to loose the overall diameter (longer contact patch) going to the 305/30. I don't track an if I do it will be 1-2 times a year so a wider shorter contact patch of the 305 will actually loose traction from dig or strait line.
that's just me tho, if I could afford it I would get the ad08r but I'd go through them to fast and it's not to cost effective for me..

if all you want is straight line dig traction then just get a spare set or rear wheel and drag radials for when you do that.

that is my plan for next year. just a drag setup to play with.

yeah thanks man I'm probably gonna do that, then for the street I'll go with the in between 295/35. it's actualy a 302 wide tire too

Go with the RE-11's. Your a stock Nismo right? If so, 285/35/19's for the front and 325/30/19's for the back. You won't regret it. Thread on here about this setup.


Now this is a meaty tire thread.

that is definitely beast mode

Ah Noop, Big Booty Trudy mode. Come join the club.

Needless to say I have been in the market for tires for about a month, tires were bald, almost at wire and didn't feel safe driving, as the Z is my DD, so had to do some budgeting as a new addition will be coming to our family soon, decided to go with V12's 285/45s and 325/30s on Nismo stockers, (aesthetics - I love the way it looks) I did beast mode big booty Trudy, I must say it is a pretty sweet setup, thanks to Vince-repped,:tup:

looks really good man, maybe next time.
I went with 295/35

Just ordered this setup with RE-11 for my 2015 nismo
Does anyone know the old nismo wheel offsets compared to the new nismo wheel offsets?

Can someone enlighten me on the tire height debate? I have a set of 285/35/19 kumho xs fronts under my house and want 305/30/19 kumho v720's but I am not knowledgeable enough to know if these heights will mess with the sensors, I'm not worried about the speedometer but more along the line the difference in height messing with the traction control or stability sensors

Seems fine to me, but I am no expert by any means. Traction is on point with this setup

btw everyone should read this, this is what I've been talking about with wide tires not being the best options aside from sexy looks. TALLER and tire compound= more traction.

the pss 335/30/19 is pretty tall tho but also adds ALOT of outer wheel edge rotational wheel weight/mass!!!

so many variables

tire physics

Mechanisms of Tire grip. Friction Mechanical Keying Adhesion As they are made from deformable rubber, tires dont exactly follow basic friction theory. So to just say that F=mu*r is strictly wrong. Although it basically does floow this during the elastic range. Tires only give grip when they are at the correct temperature. this is the most important thing you can remember about tires . Now on to business. Tires are the most important part of the suspension, either they are designed to fit it, or the suspension is designed around the tire. People who say wider tires make more grip because ;''there is more rubber on the road' are wrong. They are both wrong that it makes mroe grip and that there is more rubber on the road. When you make a tire wider, you alter the contact patch to be wider , but it reduces in length. So depending on sidewall stiffness, a wider tire can actually give less rubber on the road. The main reason for tires being the size they are is actually heat management. Wider, low sidewall tires will cool better than narrow tall tires. If you can;'t get a tire up to temperatie it will give no grip, if you get it too high you will cook the rubber and ruin the set of tires. Back to contact patch, you can safely assume that contact patch stays roughly the same area with wide or narrow tires (as long as the load stsys the same). Narrow will have longer contact patches and wide tires will have shorter. The reason why F1 tires are wide is primarily so that they dont cook (remember they arent just wide, they are fairly high sidewalled), but they ten to have wider contact patches because they will give better grip going round corners. A wide tire will generate more lateral force per slip angle making cornering better. F1 cars DO NOT have wide tires for linear acceleration. Conversely drag racers acutally use the tires not becuase of the width, but the tallness. As we know a wider contact patch gives better cornering performance, a narrow but long contact patch is what you want for linear acceleration. so strangely, drag racers will actually be better with narrow tires. So why do they use wide tires? (remember the most important grip aspect of tires) Temperature! They want as longer contact patch as they can get, but need the width for cooling. (with 4000+ horsepower you do kind of build temp rather well) But if you look at the contact patch shape between say, an F1 car or drag racer. (both are considered to use wide tires). The F1 patch will be wider and shorter for good cornering, the drag patch will be longer and narrower (relatively) for good linear acceleration. So to sum up: Wider tires are not always better. They dont always give better traction. It depends on the car, the situation, the conditions. Eg. Rally cars use wider tires when on tarmac rallys, and use (surprisingly) very thin tires on ice rallys. F1 cars used to use narrow tires until aero began to be used in the 60's. Drag racers acutally want tall tires, width is there to stop the tire being destroyed. TEMPERATURE!!!!!! rawr. As example I can think of is formula student cars, they used to use 8inch tires but couldnt get them up to temperature. They switched to 6.5inch and got more grip because they can get them up to temp. holy beep thats the longest post i've ever done. I should do a summary.

Statement by RBfastback is True; at the strip,a narrower tire w/more sidewall will bite better....more psi on the tire. & look how fast cars are going on 275's.
My reasoning for going wider,would be strictly for looks & on the street....but at the track-everyone has their own little details (not necessarily published) to help them along.
Example.....My ~Z~ went 1.95 in 60' w/275 all weather tires on 18's w/open diff 3.359 gearing......
some will say WTF....but planning to go 1.60's this spring N/A
Good Imfo RB!
