27540ZR19 for rear tires?
 

Got new tires the other day. Had to change the rear tires for there being a slit in the sidewall of my old rear tire. Got pirelli p zero Nero all season which is what my front tires are. Any thoughts on this size of tires for rear? I'm liking the feel of the drive on them so far

Unnecessarily tall. It's 27.7 inches, stock is 26.9

:iagree: Won't that much of a size difference confuse the ecu enough to cause problems?

I wonder why it'd cause ecu problems? When I got these tires all the 275 came in was 40r or 40zr at its lowest. I wanted to get 275/35 but I wanted to match the same brand and tread as my front tires & I didn't think this little size difference would make a difference?

The width is fine but a whole inch taller is more than a little difference.

Guys will run a 28" tire at the drag strip, but that's only 11 seconds at a time :)

i forget what the limit is but its not the tire height itself that will trigger an ECU issue, but the difference between front and rear tire height. So depends what you're running up front that determines if your speedo will go wonky

the bigger issue is . . . why would you want to go taller? looks worse, performs worse generally

drag guys run taller tires because they're specifically trying to get to a certain gearing (top speed!)

I just got this car recently and this is the size the previous owner had on it and I had to change the rear tires due to one of them having a slit in the outer wall. I wanted to match the tire brand and tread on my front so I had to get the same brand and in 275 that's the smallest height they came in :/ I blame the previous owner for this lol

Will I just be okay to run these until it's necessary to change them again? Or do yo guys recommend to change them right away

Oh and option zero I'm running 245/40zr19 up front

if ur dash isn't lighting up with error signals there's probably no issue

but FYI:
Pirelli*P Zero Nero All Season

Says this tire does not even come in 245/40/19 so u might wanna double check

also, 275 is the WIDTH not the HEIGHT

height is measured by taking the width, multiplying it by the aspect ratio, then . .. a, ****, the math is stupid. Just stick it into a Tire Height calculator. google it yourself


lastly

buying stuff then asking for advice is pretty dumb. research and ask questions AND THEN spend money


based on the sizes listed i wouldn't run that tire at all. i'd just get some bridgestone 04 in OEM sizes and be happy.

Option zero- I just checked my tires as I speak the fronts say 24540zr19 so I'm not sure if they're DC'd now or what but that's what I read. I'm not the one who got these tires in the first place since I bought the car used. And I'm very OCD about doing things properly when it comes to my cars. I tried researching on this forum if that tire size is okay.. couldn't find much. So I asked around to some people I know who know quite a bit about cars they told me I'd be okay..

And fronts also say P zero Nero all season

Get 285/35-19 if possible,the best match...275/40 can blunt the performance of the Car.

That specific tire doesn't have that size.. I might just need to return these I have on and just get a whole new set of tires... kinda ridiculous I need to do this after just getting this car. The dealership should have proper tires on the car from the start!!

Oh and I'm wondering how does this tire size affect performance?

Shorter tires will gear you lower & acceleration will be quicker through the gears

OCD,,,look in the door jamb & it will tell you what size came on the car...if it still has the factory wheels it came with.

And since when do you have to run same tires front and rear?

Yeah Ive checked that out already.

What sizes you gonna be running front and back? Those tires look beefy

I run 18's so subtract 5 off each sidewall for the equivalent in 19"

F: 275/40
R: 325/35

Have you ever rode in that set up before?

Put these tires to the test today, since it was a warmer day out today I figured it'd be a good day for it.. anyway, car seems to have fast acceleration and also didn't have any traction lights come on, abs lights, etc. I think I'll just keep these on until I have to get new tires again and next time around I'll get a different set up. Maybe 255/40/19 front and 285/35/19 in the back

With your 245,275/40/19 setup; this may be the most diameter differential I've seen without causing the Christmas Tree effect.
Around a 3.5% difference @ right at a full inch taller in rear.
Is your Z a Sport with 9/10 stagger or 9.5/10.5 Nismo stagger?

Yes I'm running different tires front and rear right now. It is the height you need to watch for not the width.

With that inch taller rear tire remember you are effectively changing your rear end ratio, which is a torque multiplier. Your speedometer will also be off now, as will the mileage you are putting on your odometer.

I have a touring

Yeah I know, that's why I'm not a huge fan of this set up. Like I said before it just sucks the previous owner had these tires on in the first place. That's why when I get some money saved up I'm just gonna get some nice summer tires for spring and summer and I'll just keep this all season set up for winter only when it's only used for a little bit.

RE-11, 245s up front 285s in the rear. Great summer tire setup that will get you a lot of miles. (40k on my last set) It does not get cold enough to be an issue here but I wouldn't leave them on (or any max performance summer tire) in the winter in Nebraska.

I'll look into those tires. My plan is to get new summer tires and new black aftermarket wheels when I get my tax return.. I am pretty excited for it! And since I live in the Nebraska my plan is for when the winter comes around I'll just put these pirelli all seasons on and swap them every winter/spring.

Putting my odometer to the test. I went to the gym this morning and looked up the miles to the gym and my odometer was right on the money. It's GTG so far. I'll keep doing tests on it

Did another odometer test from the gym to my work and it was perfect again.
