And would you put a 26 pound flywheel on a built SR or LS? No way, but that's how much extra rotating mass the Cobra wheels are adding over the RPF1s. I was presuming that someone who wants to run 315/35/17s has 400+rwhp with traction issues and therefore isn't a 16 year old using a paper route to fund his build. If one can afford a proper LS swap and wants traction, that person already knows you have to pay to play.

I think you will run into some issues trying to fit 275 on a 9+22 in back, but that's just imo.

I run 255 on a 9.5 +38 (s14 subframe so +33 effectively) and it's very close in the back. Despite the pic making it look like it has positive camber, i run about -1.5 in back.

I have 275/40/17 17x9.5 +38 rear with a roll and pull and they don't rub on the fender or inner fender well, but depending on the ride height and alignment I have had the rub on both the inner and outer fender well. It is not an easy fit, and Nitto NT05s run small.

Basically I am buying time until I can go +30mm widebody then switch to 17x10 +18 rear but I am at max tire right now for my fenders

[e1_griego]

Having owned both coupe and fb with all the same parts (literally) I think fb's fit a bit more tire in back.

The 255 rs3s run wide, though, too.

i get what your saying, but there is a big difference between rotating mass on your engine and your wheels rotating mass.....

[Seraphim38]

To your point, it's surprising how Mustang guys rush to spend 500 bucks on a lightweight driveline but roll with wheels that weigh a ton.

For my car I have observed that weight reduction $ have been worth it, as I can perceive a good amount of performance improvements with better weight balancing and less overall weight. I haven't run Cobra wheels and RPF1s back to back on my car to gauge the seat of the pants difference but 32 pounds of rotating mass for both back wheels has to amount to a material difference...

I am also looking at RPF1's in 17 x 9.5 +38 for the rear of my S13.

I am still looking into which 275 or 265 tire would be best for my 500 WHP LS3 setup.

Do you have a picture of how much clearance you have between hard parts (rim to shock, etc) in the fenderwell?

Doesn't seem like I can run a 275 up front so I can rotate tires.

What wheel size/offset do you have up front? Have any clearance issues with hard parts during turning lock to lock when susp is compressed? I know tire to harness clearance may be an issue.

[e1_griego]

17x9 +22 in front with 255.

I don't have clearance pics in the back -- but I know it doesn't rub anything, besides the fender if there isn't enough camber or if the car is too low.

[sean1]

anybody have any experience running battles on a s13 with decent tire sizes? all the ones i see are 215's or 225's

[jaysgottaredtop]

^ two local guys (one s13, one s14) are running 17x9.5 +15 battles with 235/40s. you could probably fit a 245 under there, or even a 255, depending how much you pull the fenders and/or camber in. for easier fitment of max rubber (i.e. 255/40s with little/no camber) you'll want a higher offset wheel, closer to +20ish.

i agree with the 275 on a 9" with a +22. I've picked up a set of 17x9 +35's and i still think fitting a 275 on the back is going to be tricky.

i would like to get 235s up front and like 265s in the back,maybe the 17x9 +30 would be better.
i have s14 flca's in the front and dont want to mess with the rear fenders that much just a roll. still trying to decide between battles and rpf1s lol

Rpf1's all the way over heavy ass knock-offs...

just as jay said, it really depends on offset, that how FD rx7 guys are running like 315's on stock rubber since the offset is like +4x lower the offset the wider you can run (stock body at least).

How much camber are you running f/r?
Im looking to run the same tire setup, if anything run 255 up front instead.

[CDD200]

315/35/17 on 17x10.5 cobra wheels @ .8 camber
not the best but will work for now, it is nice having traction now...

[Yellow4g63]

Whats the offset of those rear wheels?

[CDD200]

^they are 17x10.5 +27 on the rear

Any side pictures?

Id like to run 265 up front

On an s13 I presume?

What kind of driving do you do?

You really can't say that a certain width up front will automatically cause understeer.

If you keep tire widths within 20-30mm front to rear, then you shouldn't have any understeer unless you have huge disparities in swaybar size/ stiffness or spring rates.

[AndyG]

YOUR CHASSIS: s13

WHEELS: Mangels,15x8, negative offset

TIRES: Firestone Firehawk p235/60/r15

PURPOSE OF CAR: street/drift (need smaller tires) I got these rims and tires for free so when i eventually buy tires i think the will be 225/50/15s.

^ nice, get some 225/50s and have a ball

Uhhh, you know this is the max tire thread, right?

[JFoxx]

^^^agree..... both the 235/60 and 225/50 do not belong on this thread...... unless your trying to go for max sidewall.......lol

Stretched tires though?

[AndyG]

My bad, all I have to say is with the negative offset of those wheels they rub horribly, so I thought they were pretty big tires for an s13.

[jaysgottaredtop]

^ unfortunately, those tires are "max" in the wrong dimension, haha. like i said, 225/50, go. it still won't really qualify for this thread, but it'll be a hell of a lot more fun to drive (with the shorter effective gearing) and look way less like Grave Digger.

[F34R]

Hello, friend linked me here and I LOVE wide and meaty fitments. I thought my setup was meaty(from the BMW world), so rubber band tires and stupid poke/camber fitment is the normal. I think maybe I will be welcome here?

These are a week old, I am currently 1.5" lower in the front with -2 degrees of extra camber. I soloX this car, so that is the reason. I have zero rub and proper sized tires =)

Artec 17x8/9 et3 and 8
Tires: 215/40 235/35
Once these tires are done I am jumping to a 245/35 in the rear.



Rear fenders used to be flush but I would rub too much under too much hard cornering...function over form!
