What size tires can i go with? from my research it looks like i can fit 245's front and rear, but id like to fit something a little bigger if possible. Thanks for any input.

10mm in front should be more than enough. And nittos MAXIMUM reccomend wheel width with a 245 is 9.0"!

You won't need a spacer in the rear, and even 275s look stretched on a 17x10.5 wheel

I agree w/ the front numbers and think they might even be a bit on the agressive side, but (correct me if I'm wrong)...if you're not running much rear camber, this number can easily go up to 185+. I borrowed some wheels (18 x 9.5 +41) to get me around until I order new ones...this has a 7" (178mm) backspace and the tire (275/35/18) bulges another 5mm and I can still fit my hand in between the tire and coil with ease (another 10mm or so) which equates to roughly 190mm of backspace.

Just something to keep in mind....all factors need to be considered before running out and buying a set of wheels (camber, tire width, etc.)

What this thread really needs is more people posting up detailed specs (camber, tire sizes, what calipers, spacers?, how much of a roll, etc.), with detailed pictures of the inside and outside fitment and measurements of how much space is left. So far, you've probably contributed the most help (to me at least), but we need people with good setups to help out and get more visual evidence. I'll snap some pics of what's on the car now, but I'm still struggling with what sizes and widths to order from CCW.

[SicBastard]

My set up with the fat ohlins shock bodies in the rear would make contact at 187mm of true backspace. I'm sticking to the below quote from my build thread on the ultimate stock fendered s14 wheel:

"So lets call it a max frontspace of 115mm and a max backspace (only to the outertire edge, aka not true backspace) of 170mm would yield a wheel 285mm (11.22") wide. If you go any bigger you're going to have to do something drastic to your fenders. Also, to pull this off, your coils will probably have to sit higher than the tire.

I would really like to own the redline time-attack street class some day. The current rules only allow tires upto 285s, and forbid inboard/cantilevered dampers. I think that a 11.22" wheel would be perfect for 285/30/18 tires. Personally I'd order up four of them all with the same <7.362" backspace and just use whatever spacer and fenders are necessary in the front. 11.22" wheel would also be just fine for 315s"

thanks for the help, so would 255's for the front be a better choice or would i need wider front fenders as well? for the rears what tire size would you recommend me to go with untill i get rear overfenders installed?

black05srt-4 is rollin an s13 with 17x9+24 fronts and 17x10.5+27 rears:

In the front 255s fit, but will of course require a little more fender pulling. I have 255 falken 615s on the front, mounted on my 17x9s, and I hate to admit this in the maximum tire thread, but they look a little goofy with their bulge compared to my rears. I almost wish I had gone 245s. In the falkens, the 245s are easier to get, and also have the reinforced side walls unlike the 255s. The reason I went with the 255s originally was of course for MAX RUBBER!!!, but also because they are 40 series, while the 245s only come in 45 series. And while wider the 255s are actually a little shorter, which is good.

These are two of my favorite street tires right now. If you go with the R1R they actually make a 40 series 255! But they'll set you back at least $250 bucks more/set of 4 than the rt615s.

R1R:http://marktg.toyotires.com/file/30251.pdf

And if we were all serious, you can see that toyo says their 275/40/17 will even fit on a 17x9! Now that is MAXIMUM rubber. Sorry there really is no clear cut answer for the front. 235-275 will fit on your 17x9 wheel. Now it's just a matter of what brand tire you want, and how much new front fender/R+P/spacer you're willing to do. If you want to just keep it simple get the 245s, and when you wear them out in less than a year re-evaluate how much room you weren't using to upsize, then post back here for the benefit of all.

I'd stay with the 275s in the rear. If for no other reason than cost. It seams the second you go bigger than 275 the price of tires doubles.

[black05srt-4]

apreciate the help! I thought the 275's wouldnt fit under just a rolled\pulled rear fender? ill check those r1r's out as well.

They will in the rear, I have no idea in the front of an s13.

[black05srt-4]

ah ok thanks!

[flamebag16]

trying to find some pics of 18x9.5 +15 mb battles or any wheels really on stock s14 metal need to see how big of tire i can fit

[hondanissan]

i'm running 265/35/18's contisportcontact3 on the rear of my s14 on 18*10+15. im in the process of rolling and doing a lil pull. the question is, camber or no camber???...cuz tires are pretty expensive. anyone have pics that they wanna post with similar sizes and NO camber?

[racepar1]

With a decent roll and pull you can run 265's no problem.

[EndLeSS8]

S14 currently on KYB AGX + Tein Springs.
Planning to switch to KYB AGX + PDM springs (1.8" drop all around)

Wheels will be Work Emotion CR Kai
17x9 +17 front
18x9.5 +12 rear

Not planning to run spacers, just a fender roll + some neg camber, no pull (if unnecessary)

Will I have any tire rubbing issues/hitting the shock/fitment trouble if I run these size tires?
235/45/17 front
245/40/18 rear

Let me know. Thanks a lot in advance

If anyone else wants help/input on their fitment, how bout everyone start showing a modicum of respect to everyone's time, by at least calculating and posting your own frontspace and backspace relative to the tire as described earlier in the thread.

[SuicidnS13]

Im going to have to run 15mm spacers in the front to clear my brakes. Will this affect my handling alot? Or do I need to run 15mm spacers all around?

Wheel Specs currently are:
18 x 9.5 +24 all around

Tire Specs are:
F: 245/40/18
R: 275/35/18

Unfortunately I don't know my frontspace and backspace.
I went to the link for tire sizes/wheel sizes, but I'm not sure of my current offset.
I'm on the OEM S14 5 spoke 5-lug wheels right now
16x6.5 unknown offset
225/50/16 tires

If I guesstimate offset to 30, then I have 125mm of backspace
I have approx 0.75"-1" of frontspace on the front
I have approx 1"-1.5" of frontspace on the rear

[SicBastard]

I believe the stock wheels are actually +40.

[EndLeSS8]

Ok, with +40 I have 135mm (5.3") of backspace

235/45/17 front on 17x9 +17
245/40/18 rear on 18x9.5 +12

Backspace, I can fit, but frontspace is tight.
Any ideas if it will fit?

[cdlong]

those sizes are hardly pushing it. if you're willing to roll, you should be able to work them in there. just a tip, when someone criticizes you for wasting the time of other members on this board, it's probably not a good idea to come back with more questions that you could have answered yourself. and why are you calculating backspace for stock wheels?

suicidns13, wider track width generally leads to more grip at that end. if anything, just front spacers will reduce understeer. you could try just front spacers and see how it works and add rears later if needed. you'll probably notice the difference more visually than in handling though.

[EndLeSS8]

The reason why I was asking is because most people on Zilvia are running on coils, which leave more room than springs/shocks. I'm on springs/shocks and I plan on staying with them. I wasn't sure if it was going to fit. I couldn't of answered it myself. I'm calculating backspace for stock wheels because I'm currently on stock wheels.

Actually the stock dampers/springs usually offer a good amount more room than coilovers! Especially in front where the stock style lower spring perch is entirely above the wheel.

Ok, thanks for the info, much appreciated. Great to hear that they should fit.

[simmode1]

Ok... I've pored all over this thread and I think I've come up with my ideal wheel/tire setup. Let me know what you guys think! This would be for an s13 with stock fenders.

17x9+22 255/40/17
17x10+18 275/40/17

I'd like to go with brands known to run small, btw. Got any suggestions? Comments on the proposed setup? Will I be able to avoid massive rolling/pulling?

[Devens240]

are you going to run RPF1's? im guessing because of the +18. but you can get away with running a much higher offset in the back, like a +30 or +40, then you wont have to pull as much.

I'd go with 9.5 +18 up front over 9 +22.. but that's me

Yep! You guys are on the ball! I would love to run the 17x10+38 in the rear, but my fear is that the high offset in back would make the lower offset up front laterally wider, creating a kind of 'reverse stagger'. Am I wrong in this?

JRas, I would also love to run the 17x9.5+18 up front with 255 tires, but on an s13, I don't see how it could fit without destroying my pretty fenders trying to pull the hell out of them or ditching them for overfenders...

[INeedNewTires]

275/35-19's on a 19x10.5 +23 doooooont quite fit on rolled/pulled fenders this low...

[PoorMans180SX]

That is so perfect.
