tire size options for my car/wheels

[tramp_drift240]

well ive got kind of a...semi-complex question that you and your infinite knowledge may be able to answer.

for my kais, and a stock s13 body, im pretty sure 225/40/18s are "best" for fitment.

but im wondering the MAX tread i could have on the rear, fitting the 18x9.5" +12, and a recommended overfender size to accommodate. perhaps spacers or whatever if needed.

i put a 295/35 on one of my wheels a few days ago, and it looked sick as hell. it made me start thinking about those Origin tatakidasi rear overs and some thicker front tires for some wide fenders.

keep in mind, this is for an s13 coupe.

damn dude, 295's are pretty thick dude, esp. for a 9.5"

Honestly, I'd just recommend going with like a 275/30... which would be a pretty square fit.

just to give some ideas on 275's...

heres a 10" on a 275

and Symond's KA-t 17x9" with 275's (rear)

but to fit those on a 9.5 +12, you're looking at possibly 50mm fenders. I'd want to say you might be able to squeeze in some 20mm's.... but it all depends on camber, and since you're going with wide tires, I'm assuming you don't want to run much.

also take into consideration, that with over fenders, you'll need to chop up your stock fenders.. ()

[sultan]

all tire sizes mentioned in this thread are too tall for s13, why don't you want to keep stock diameter?

[adrianfromthecastle]

^^ you're right. I meant 30 sidewall... I editted my original post.

[tramp_drift240]

yeah i know theyre too tall.

but what sizes are within the 24.2" diameter limit?

in all honesty, its kind of hard to find the right tire size, after trying to guesstimate stretch and whatever. i just figured, with a 9.5 inch wheel, i should have more than a 225 on the rear, y'know?

yeah 295 is wide, but the BFG competition radials look SOOOOO sick on cr kais, i guess.

and i think id like to stick with a 35 sidewall. 30 sounds weird, and is even smaller.

im not gonna lie though, a 295/35/18 on my wheel with some 50mm tatakidasi overfenders sounds pretty damn sexy.

ALSO

what size wheel and offset are the wheels on that hatchback with 275s?

im trying to establish what room ill be using, and what ill need to cover it.

and i know id have to cut my fenders to go overs, especially with the ride height im wanting ( )

but i AM gonna buy the PBM fender roller to try to work some magic before jumping up to a raped-quarterpanel with overfender, ya dig?

[adrianfromthecastle]

not sure... I wanna say like +25 or something

and i think id like to stick with a 35 sidewall. 30 sounds weird, and is even smaller.

dude, 275/35 is gonna have an od of like 25.6... I'm tellin you dude, go with 30

[tramp_drift240]

why did you quote that.

theres a 275 35 at work that ill try to mount on one of my wheels.

what size front should i go with if i end up going with wide front fenders?

and keep in mind, if i dont make up my mind about the tire size and stuff, ill just be getting 225/40/18 BFG g-force sports all around.

ALSO, the only overfenders that im really interested in are the tatakidasi, which are only made in 30mm and 50mm.

that is aimed towards Adrian saying 20mm.

[adrianfromthecastle]

well, this one was in one of the stikied FAQ http://www.csgnetwork.com/tireinfo4calc.html

but the miata one works faster and is easier to use http://www.miata.net/garage/tirecalcold.html

[tramp_drift240]

you realize to use that, i need to have a wheel size that is equal to the flushness with the stock quarterpanel so i can see how far out itll stick.

PLUS, those calculators dont apply the stretch factor, or the specific tire and wheel combo factor.

they just assume that if youre using a ______ tire size, you have the wheel that'll perfectly fit that...

[adrianfromthecastle]

huh? it doesn't have anything to do with offset, nor does it say.... that's all on your own knowledge

PLUS, those calculators dont apply the stretch factor, or the specific tire and wheel combo factor.

stretch factor, no..

but we're not talking about stretching here...

you're looking for fitting tires.

they just assume that if youre using a ______ tire size, you have the wheel that'll perfectly fit that...

dude, you put it stock tire specs. then you put in your tire spec, and it shows how much off OD you are. Of course when going with any other tire or wheel that isn't oe, its not gonna be perfect... but you wanna get it as close as you can.

[tramp_drift240]

adrian, youre being mean now.

ill try to figure the stuff out, i just thought that id be able to get some good info by posting in here.

i just know that itll be hard to find a good size thatll somewhat equate to the stock speedometer gearing.

i do have a cop in town who will go on a run with me to tell me how fast im going at __ speed. so thats good i suppose.

[adrianfromthecastle]

adrian, youre being mean now.

lolwtfbbq?

[tramp_drift240]

one last bit of info needed.

more of, an opinion or suggestion.

should i just stick with 225/40/18s so i can run it low, then later on when i have bukoo bucks to spend on other stuff, i can up the tire sizes and do the body mods?

itll be cheaper, and i can see how i actually like the 225/40 with stock fenders.

[tramp_drift240]

for some reason im still really bothered by putting a 225 on a 9.5

anyone think that, with stretching involved, a 235/40/18 would fit alright after some rolling and pulling of the front and rears?

AND, A-symmetrical > directional?

i think you should just do that. you might realize it was a bad decision to just go ahead and buy overfenders/expensive tires.

see how the 225/40 or 235/40 fit before throwing out so much cash

dude, 40's are huge. I'm thinking about going 235/40... but I'm on 17" lol.

but seriously, 225's on a 9.5 isn't that bad of a stretch, but go 235's I think you'll like it. I really recommend you go down a notch on the sidewalls. Like 235/35. 235mm's is about 9.25 inches width anyways, so you can imagine, the stretch would be very subtle.

[tramp_drift240]

as far as i can find, there are only 2 tires available in a 235 35 18.

and theyre both really expensive.

[240lookis]

these may be helpful. i ofund these in the wheel fitment whore thread on zilvia. he's running 18x9.5 +12 cr kais so same as you. tires are 225/40 all around.

[tramp_drift240]

i certainly hope you dont think that ive never seen those before.

ive a picture of that car as the background on my phone. and on my computer monitor.

i know those are 225/40s, but it just seems like there could be more tread on a 9.5 inch rim.

[adrianfromthecastle]

yup... 40's sidewall compensates for that stretch... thus why I recommended 235/35. The profile will look very similar man... I mean, you're asking for a stretch.

oh and btw 240lookis, I moved your thread linking that zilvia thread... c'mon man, you know that won't fly with the admins/mods here...

lol... dude, what do you expect? You're rocking 18" wheels, everythings gonna be expensive.

but yea, I check the federal site, and theres no 235/35

[240lookis]

to tramp: just trying to help

to adrian: sorry man. they just have a really good fitment thread. trying to help some people out.

to adrian: sorry man. they just have a really good fitment thread. trying to help some people out.

no worries man.

lol... go on zilvia and link a nico thread on there and see what happens. you're lucky they removed the rep function, lol

[tramp_drift240]

^ LOL

yeah man, im pretty sure i can only get PS2's or those BFG KDWs in a 235/35 and theyre both a good bit over 250 each iirc.

i guess a 225/40 wouldnt be that bad. for the time being anyway, i can always do body mods and up the tire size later on.

should i go Asymmetrical or directional though?

[Speckid14]

If I have rolled fenders/overfenders will that increase that 24.2" maximum diameter??? Accomadating for a bigger tire. Unfortunately there are not a whole lot of options when it comes to 275/35/18, Nitto makes there NT01 in that size however it has an overall inflated diameter of 25.55", Too big. Sorry for the thread jack, it is closely related though.

Also is the maximum diameter different on the S14?

I would go with directional, I have had good experience with them in the past. Its personal preferance though.

Speckid

[tramp_drift240]

directional tires chop easier than asymmetrical tires, from what ive seen at work. plus, if necessary, i can move them from drivers to passenger side.

the fenders and overfenders have nothing to do with the expected diameter of the wheel, the OD is used to get the speedometer to read as closely to factory as possible.

stock tires on an s14 are 195/60/16 or something, so theyre a little bigger overall than an s13. they can have larger wheels with less problems.

i think ill just go 225 all around for now, and when im able to afford body mods, ill up the tire size and fit them.

probably asymmetrical, too. ive been looking at the goodyear Eagle GT's, and falken azenis, i just dont want the tires to run out way faster than i want.

You totally misunderstood me. I didn't mean the OD in relation to the speedo, just in the relation to fitment. (ground to fender). I also didn't mean the expected diameter of the wheel (not sure where you got that) I meant the overall diameter Tire to Tire with rim in the middle. I got my measurements off of Nitto website. Those numbers included wheel size. Sorry for the confusing sentences.

I don't care if the S14 tires are a little bigger overall, that doesn't change the maximum capacity of the wheel well (ground to fender). I am curious if I can fit a 25.55" OD (tire to tire with rim in middle) on my S14. I have overfenders 30mm in rear and 20mm in front (only going to run a 245 in front).So will these Nitto's fit?

This is what Broadfield rocks on an S13 coupe, this is identical to my S14 except for I have 9.5" wide all the way around, and my offsets are +12 rear and +22 front.

Sorry, I dont mean to be rude, just want my question answered. Again, sorry for the confusing sentences. I need to pay more attention in my composition class I guess .

Thanks, Speckid

[tramp_drift240]

totally jacking my thread.

and my wheels are 18x9/5 +12 all around.

[Speckid14]

haha my bad, do you think it is possible though, we kinda got the same problem, except I for sure want to run a 275 on the rear.

[tramp_drift240]

dont get me wrong, i can run as huge of a tire as i want, i just want to stay near the stock OD.

if you dont, thats straight. run whatever you want, and itll be easier since the s14's stock OD is slightly larger than an s13.

you should be straight.
