like it says i made an error ordering new tires will 245's 40 fit the stock tc rims?? im also on sportlines.

 

it should.

youll have a lilmore rubber

stock is 225/40

 

thanks thats what i was thinking what do you think about rubbing?

 

i dont believe ull have a problem until 255. and thats barely rubbing. if u drop it. a tine bit of rubbing on 245. nothing to worry aobut tho

 

thanks

 

i saw some 245's 2 days ago, they were close, on stock suspension

 

im rinning 245s on my SC. the TC shouldnt have a problem since the wheels are wider

 

245\40's will rub in tight turns....... I've tried this size already on stock springs... On sportlines... total no-go.... I do have a bigger tire in back for looks though, it's a 255\40 and since the rear stays put ( no turning) there's no rubbing... The continental contact 3's that come on the car stock can be ordered in a 255\35\18 which I'm doing to the rear..... and, a 245\35\18 front might not rub due to shorter sidewall height....... The conti contact 3's also avail in 245\35\18.......

On the contrary\wrong, wider means they'll rub on the fenderwell in turns......especially with a 40 aspect ratio sidewall... do a 245\35 and you'll be golden.... take my word for it... I've been here done this........

 

ive worked with many people and tires

my buddy is on coilovers with 245's and hes fine int he front

he said barely any rubbing. and its just plastic thats rubbing.

 

ah i didnt read that he was asking about a 245 40 , im running a 245/35

 

Going from 225/40 to 245/40 will throw that speedo out of whack some careful. I'd shorten the side wll to 35 unless you are doing some major track racing.

 

i just got them installed today and they fit perfect with no rubbing but i think if i went any wider they would rub. how would it throw my speedo off they are the same height other than they are wider?

 

It's an aspect ratio.

245 is in mm and 40 I believe is a % of the width.

So a 245/40 will have a slightly taller sidewall than a 225/40.

Man I want to get some wider tires now. In hopes that I can get some traction in 1st and 2nd.

Hope this helps in any way.

 

had that size on my t/c
have one azenis if you want to buy it sellin for dirt cheap

 

Huh, now this is wierd. I ran 245/40 18's on my dropped on Sportlines sedan and they never ever rubbed even once. I wonder why they'd rub on a stock hieght coupe.

 

question, any of you guys running wider tires experiencing sandblasting on the rocker panels and rear wheel well bulge? Mine is doing this on the stock tires.

 

Good point, I never put that into consideration!

 

so 245/40/R 18 's work?

good

btw 245 is the width

40 is the height

ur sensors for ur tires for the speedometer work off stock size tires. so when modified. it changes by like 1-2 MPH

 

Yes, they should, but if you are lowered it will be very close to rubbing. Stock height it should be no problem.

 

cool

just saw rissas car yesterday.

god 245 invos would look like sex on that car. lol

 

Do you need a towel now?

 

here are some pics of 245's on sportline's

 

very nice man

nah no towel until my car is done.

 

You said they looked like sex.
