Has anyone tried to run them? I remember a Guy a while ago running nt-05 tires in that size but don't remember if they rubbed or not. Got an awesome deal on some Mickey's.

 

I'm running 245 40 18 nt555s and lowered on ksport springs and after settling I scrape going around turns at speed and turned onto hills

 

One guy ran some 285's for his track set up.

 

I'm running your exact same setup with no problems at all

 

Ive seen some 255s posted on here.

Heres a link to a guy that ran 255s on 17's....

But if you want a good answer from one of the best people when it comes to deltas hit up the op in this thead. This guy he should have a good answer for you. He also makes some very nice parts for these cars! .

powells car is 5x114.3

 

Yes I know. PF01s arent available in a 9.5 on a 110 bolt pattern. However powell will know best just from his experience.

 

245/40/18 will rub on with certain tires on a 18x9. all depends on the sidewall design and your ride height. stock ride height or a slight drop will be fine but too low you will need body work to tuck them enough. 18x9.5 is big and will require some body work. the redlines are a lot more forgiving then the cobalts and johns fenders and quarters are rolled.

 

True. I have 235/40/18 kumhos and they seem to run a bit on the small side.
Im not sure of a cobalt running an 18x9.5 currently.

think most are on 18x8's. But john will be able to advise him.

 

john and i have dicussed this indept.....unless you do body work your not getting 9.5" rim in there period. a 18x9" rim witha 35mm offset is doable with rolled lips and 245s which will have a very slight stretch

when i had h&r springs on there(looks only) i rubbed with both the continentals and the re-11s. with the stance coilovers i still rubbed but i was at almost the same ride height. both 225/40/18.

 

i mean op... are you looking just to drag race these and have a seperate set of tires for the streets?

 

Yeah and I wouldnt go over a 235 on SS/TC wheels either. I know plenty of people have gone 245 though.

 

Probably drag racing is my bet but will probably want to run them on the street

 

they can be ran at stock ride height. might want to put some drag bags out back and make them real stiff to avoid rubbing.

 

he's on ksport springs and sits fairly low.

 

more then likely going to rub. especially if hes on a 18x8 he will have a more protruded sidewall as 245s are ment for a larger width rim.

 

Good question. I'm running 18x7.5's on 225/40/18 and about to trade for some 245/40/18..Will they rub?

 

it really depends....the sidewall comes into play some dont some do...ones i know do are the star specs and re11s for sure. what are you dropped on? i wouldnt put 245s on a 7.5" rim though.

 

Dropped on H&R's..I've had 245's before but they were on 16" rims..

 

i rubbed with 225 40 18s on h&r springs on a 18x8s....pretty sure you will rub

 

I have 245/40/18 NT-05's on my sedan.... no issues at all other than actually having traction.

 

will not work on the stock 8in wide rim.....
for a drag set up 265 is as high as id go but you wont be able to turn for crap!!

street and daily drivability id stick with no bigger than a 235/40

 

exactly different sidewalls...... i know if i had 245 re11s i would rub

 

SS/TC wheels arent 8 inches they are 7.5 so 245 is a bit too wide for them.

Yeah the tires will fit its just a bit too wide on the wheel to be optimal but it works and looks good.
