would 295-35-18's in the rear make an NA Z slower?
 

exactly as the title emplies. will having extremely wide rear tires, say 295's, make an NA Z slower?

yes

what would be a good size to run in the rear? considering i have 245's in the front. and would the slower acceleration be felt behind the wheel?

w/ 245's in the front and 295s in the rear, you'll have monster understeer

Next time i upgrade tires, im going for 265/35F 265/40R. That'll make it slightly oversteer on stock suspension. With upgraded suspension, depending on ur setup, it should be neutral or slightly oversteer. Wider isn't always better.. If you want higher grip, upgrade the tire, not the size.. I wish i would've known that when i first bought tires

i use a 275 tire with my 20s

run 275s

275/35 or 275/40, whatever matches up better

wider tire doesnt necessarily equate better...a 295...thats super overkill

its a 350z, not a ferrari or lambo ;)

just keepin it real

i run 285,35,18 in the rear, and i just got the falken fk452 and i like it.. it works for me

245/40 front, 275/40 rear

or 245/40 front 275/35 rear (what I run) are the most common setups

adam do you get any TCS errors w/ the 275/35 w/ the 40 in teh front?
Next time im either going to run 255/35F 275/35 or 245/40 265/40.

no problems on my car

275 is more than enough for NA.

If you get 295's you will need to pair the fronts with 265's or else... Hello understeer.

Also, here some info about proper stagger:

would 275's be good in the rear, considering i have 245's in the front. or should i just get 265's instead and save some money?

255/35 front 275/35 rear
do I get oversteer or understeer?

Unless you drive your car like you stole it, you won't notice a difference. But, next time i upgrade, thats the setupim going w/.

LOL I must be doing something wrong lol, Im running 255s in the front and ....... 305's in the rear OH YEA lol, but thats for daily and for the nice wheels. I have r comps on my stocks 265's all around for the track so maybe I dont count lol.

^wow, do you have any pics of the back of your car?

My dad has 315's on the Porsche and 325 or 335's on the bmw 4.8is but I've never seen 305's on a Z before.

what would you guys say for a 18x9 et22 front rim? a 245 or 255? and on a 18x10 et25 rear?

Thanks guys. Need tires BAD. :(

I am running 295s in the rear, and I haven't noticed any difference.
It all depends how heavy the wheel/tire is also.
