Widest rear tires on a s14 chassis

[mmdb]

Anyone know the widest tires that'll fit on a s14 body (95-98) with minor cutting/bending of the wheel well? thanx in advance.

[Dousan_PG]

depends on wheel's width and offset
stock suspension? coilovers?
stock alignment?


be more specific

[sykikchimp]

I've seen 10.5's under the OEM fenders..

but like Aaron said.. depends on other factors

[The Mole]

what about widest tire size that will fit on stock SE five star style wheel?

ive heard 245's

[Jeff240sx]

245 would be a really nasty looking setup. I think 225 would be about the largest you'd want to put on them. Even 215 would make a large bulge.

i have a friend at a tire shop and he said he put 245s on another s14 and it was fine

Fine if you like an unresponsive car w/ balloons for wheels, bud

[The Mole]

i didnt mean anything by that "bud", i was still asking cause this is what i was told

[mmdb]

thanx for the replies. This wasn't suppose to be a physics question. Given the best conditions (coilovers, etc etc) that factor in suspension set ups. What's the widest size wheels that'll fit? thanx again in advance

[Evil S14]

it looks to me that 225-245 looks good for a 7.5-8 in wheel
255-275 for a 8.5 to in wheel
and then go nuts after that

That's huge!

But now that I think about it, some people like the way tire buldge looks some people dont'.


Mole: reread your post, there was no question stated. Don't take it to heart, I'm just not a fan of small wheels big tires.

[The Mole]

whatever:p

no biggie:D

[AKADriver]

It isn't even about looks... 245 is just plain unsafe on a 16x6.5. 225 will work, though. I dunno what crack your friend the tire guy was smoking... I don't even think a 245 would clear the suspension with the stock high-offset wheels.

[Red]

I'm guna do 245 all around. I'll flayer it later and go 265 all around next. Not always usefull.. But I don't care.

[boosteds14]

hmmm. i got a 9" rim in the back with a 265 tire.

its not that wide,

245 clears it bulges like crazy on stock SE wheels (had a pair on the back for a week waiting on a new set of 225s to come in) but clears everything... but Im running apexi world sports too... and I only had them on the back.

[Hubie]

Since were kinda on the subject. Is it safe to stretch 225 any brand and model tire on a 9" wheel or is it safer to do it with a more expensive tire. I'm looking at the FM901 and the ES100 or would I have to pick something like S03's. Thanks.

[AKADriver]

Maximum wheel width for a 225/45-17 is 8.5" for pretty much any brand. A few competition tires in that size will fit on a 9" wide wheel, but street tires won't. Silly idea anyway, just get 235's or 245's.

[Hubie]

Ok, thanks for the reply. I may be picking up a set of wheels 17x9 +18 so I guess I'll just play with the tire sizes and pull the fenders a little if needed.

I was just wondering if those tires would be able to take the loads on the sidewall if stretched.

[AKADriver]

well, they *might*. I'm just going by the tire manufacturer's recommendations which are a bit conservative.

[sykikchimp]

is 225 really that narrow? 8.5" - ~216mm I would think you could put 215's on an 8.5 in wide rim?...

[Infamous]

:o ..... whats the widest rim/tire set i could fit on a S13 chasis in rear? assuming its lowered no more than an inch, with everything pretty much stock:)

[the3SecondJerk]

I have 225s all the way around on my s13....it's fine.

[SicBastard]

If anyone else has something usefull, please post proof with pics!
Here's the images that I've stollen from all over the place in my research.

315! What! My rears are 17x10.5 +27, I don't know if that's enogh offset to run the 315s. Most guys that go 275 or bigger run +30, I wish I knew what this guys offset was. I'm going to start at 285s since that's the biggest that the Kumho MX comes in, and if it'll take more with my +27, then I'll upgrade to 315 Kds. If anyone knows this guy, find out his rear wheel size and off-set please!

This guy is running +0 in the back. Imagine what you could do with an extra 27mm+ or more of offset!
225/45/17x9 +0 stock s14 rolled w/ minus 3 camber

Here is why I will be running 17x9 +0 in front:

I personally know some autoXrs that fit 245s in the front of a s14 with no issues. But then again you'll never hear an autxr talk about "stretch". If grip is what you're really after, and you can't afford wider wheels, then the widest tire you can SAFELY fit will always give you faster lap times, even if it does cost you a little "feel". A skilled driver can compensate with the extra grip for the loss in feel.

[SicBastard]

From me:

Wheel size + 0-20-40mm usually gives you the perfect tire size for grip.

7 177.8
7.5 190.5
8 203.2
8.5 215.9

Wow, you should've just made your own thread, this one is 3 years old.

[mistert]

theres actually absolutely nothing wrong with a 225/45/17 or 225/40/17 on a 17x9 its not even a huge stretch, 215 would be a big stretch. i was in the tire shop yesterday (i had 235/45/17 dunlop fm901 mounted, im thinking about rotating them to the front and mounting a set of 255/40/17 pilot sports i have on the rear) there was one tire company's brochure that even listed 9" in the recommended size range for a 225 width tire. they also said you can mount a 295 on a 9". pretty far off from kuhmo's recommendations, i guess they recognize that some people get creative with tire fitments?

[SicBastard]

Falkon do you know of a thread that has better info then I already have? This was the closest I could find? I'm kinda new to the forums, will I get more hits if I post somewhere else? It probably doesn't matter now anyway. I'm pretty set on my 17x10.5s +27 in the rear, and I already have some 17x9 for the front that were specially made to clear 13" cobra brakes. Once they're mounted I'll make my own measurements b4 I get serious with some 3-piece wheels.

There's a rediculous amount of engineering that goes into tires. I don't think "experimentation" beyond the recommended parameters is a good idea.

Like with the broschure you mentioned though, engineers work in the engineering department, but it's the marketing dept. that makes broschures.

Go figure it out. .. .I've got 10's w/ a negative offset. .. .Pulled not rolled

[Nizzan4u2nv]

With 17x10.5 +27 you arent gonna be able to put that big of a tire. That size is equivalent to a 9 +8. You arent gonna be able to run 315s without a pull and some camber. 285 is gonna be pushing it also. I run 10 +7 with about -3* camber with a 235/45/17 and theres hardly any room with just rolled fenders.

BTW keep in mind that a +27 offset on a 9 vs 10 is different. I use this as a reference:
http://www.1010tires.com/WheelOffsetCalculator.asp

[brainfood]

215 or 225 stretch fine on 9's
I run 225's on 9's all day long with zero problems even air pressures below 20psi never de-beaded a tire. I have seen 205's on a 9 and I have personally mounted 225's on a 10" wheel for a customer and also 245/35-19 on a 10.5 so lots of people stretch with no problems. I think a lot more in japan also or check out '86 guys 185-195 on 8's and 8.5's or vw gti guys run crazy stretches. Lots of people do it with no problems but def. watch air pressure because when it gets low it will de-bead.

meh, who cares if this is an old thread. He added decent info with pics!
