Thanks in Advance,

245/40/18.

I'm run'n 225/45/18. it depends if your planning on dropping it...if you are than run 40's

A drop doesn't have too much to do with the difference between 225/45/18 and 245/40/18 bc I think they're a similar diameter. The g35 18s are an 8" rim so I personally think 245s look better than 225s and wider is better...

I guess? All I know is the 245/45/18's I ran, rubbed in the back.
Then I switched to 225's and it's all good!

I am running 255/35/18 on my 5.5gen with a 2" drop.

i had 245/40/18 on my Gs when i had em, loved em...next set i got was 235/40/18..had a stretched look...i hated em, ended up trading for the wheels i have today

When i had the 245/45 they rubbed too, that's why I went to 245/40s....

225-40-18 tires are the cheapest, but that size will throw off your speedo but only a little bit like 1-2 mph
235-40-18 is best if you don't want to throw off your speedometer
245 is too wide IMO

I went with the 45's. We have alot of potholes and such in chicago. I like having a little more sidewall on my tires. That way I'm not blowing tires. And a 45 is still a very low profile.

So, I guess the answer is...there is alot of different sizes you can run. Lol

Its all preference?? ;)

No 235/45/18 is ideal because it retains the closest diameter/circumference to OEM tire/rim combo. These tires are also expensive.

225/45/18 all around if you wanna be cheap and save money on these specific rims.


245/40/18 all around if you wanna be cheap and save money & are running a staggered for example (i.e 8.5 in the back).

Sounds good to me. But, my tires ur not cheap? Plus, I think the tire rack calls for a 235/40/18 as recommended and no one mentioned that yet??

I spent 190 a tire. And I think the 40's were only 30 bucks more a tire.

Sounds like he has some options....

Stock:
225/50/17 = 25.9" diameter

Options for G35 18":
225/45/18 = 26"
245/40/18 = 25.7"
235/45/18 = 26.3"

There you have it OP, they are 18x8" rims so you can run anywhere from a 225-255 width. Its up to you want you want...its not about being cheap either.

Yea, I'm not cheap! ;) lol

The answer COMPLETELY depends on what you want from the car. Are you gonna slam it so you tuck rubber? are you trying to track it at an auto X event? are you looking to negate the fact that the wheels are staggered? Are you worried about retaining accuracy in the Speedo? ALL these questions need to be answered before anyone can give you the "BEST" answer.....anyone that tells you different is either lying or doesn't know any better.


an example is my wifes I35 in my sig has 225/40/19 on a 9" wide front wheel but she tucks rubber and doesn't rub at all? but she doesn't auto-x and could care less about the speedo being dead on. Oh and she ran the anniversarry edition Z wheels for awhile on hers too but we stuck with the stock rubber sizes.

All,

Thanks for the responses.

SOme additional info

I dont plan on lowering the car, I dont want any rubbing issues, I want a clean look with some wall but no bloons,

TIA,

DC

I went with 235/40/18. I'm pleased with the look at the performance. . .

245/40/18 Rear
225/40/18 Front
I'm lowered 1.8F and 1.6R on Megan springs. When I get coilovers and max them out ill just get my rear fenders rolled or pulled

I love your wifes I35. Looks awesome! Kudos!

^Thanks, I think she did a nice job of putting it all together style wise.


there are a few options because you should have any issues with rubbing etc at stock height or even near stock height. I personally would run a 215/45 or maybe even a 215/50 depending on the actual stretch because you would fill the gap some more but not get a ballon effect on the sidewall and still have a nice turn in with the stiffer side wall from being stretched. I would not run the 245/40 up front as it will have a slight balloon and be sloppy compared to the rears. if you want a very stock feel and still a bigger look you may just want to run a 235/40 but they aren't cheap...hope this helps some.


And here is the sickest calculator ever. (not all tires manufacturers products stretch the same so the calculations on stretched tires may be slightly different but they are damn close)

^ I agree with you. You can run anything you want, from 215 to 255.

Can you go with stretch? Sure. Does it run the risk of bending your rim over pot holes now. Yep.

Can you go with a fat side wall? Sure. Do you wanna rub on the loose stock suspension, or if you're dropped? Up to you.

With that said, my post was based on speedo accuracy/matching up the diameter/circumference CLOSEST to OEM tire specs (215/55/17, for i35 for example). Your link, as well as http://www.miata.net/garage/tirecalc.html can explain further why (to those that dont understand).


On my second point, and as a general rule of thumb, 225/45's and 245/40's are comparatively cheaper to buy than 235/45. If you need more proof on that, price out on tire rack.

I have rolled fenders, realigned my rear beam after a 1 finger gap drop all around (not pictured in sig), with a very stiff preload and dampening, still occasionally have a very slight rub on 245/40s on my track edition wheels. 18X8.5 +33.

Well, just wanted to update; I ended up getting some lightly used michelin 245 40 18's for a deal. I love the way the wheels look on my I30; much more agressive IMHO and the steering feels much stiffer.

Thanks for the recommendation guys!

MERRY CHRISTMAS!!!:santa:

Have pics? Would love to see the stance.

Better late than never I guess
 

Here is a pic with the wheels,

I'm overall satisfied. Thanks guys:D

Looks good. A moderate drop would set it off. You wouldnt rub either. Noticed that you didnt wanna drop because of rubbing issues....

Looks good! Looks like my ride in black..

Yeah, I saw yours posted in the audio forum awhile back(think it was audio, after you upgraded the bose). Clean car.

Thanks for the compliment.

Welcome buddy! Hey, just my opinion....you should lose the pin strip!?!

Wow didnt even see it till you mentioned it! :sprint:

Yeah, bought it like that from the original owner, old Judge from DFW area, all wor done at Sewell Dealership. I guess I was willing to deal with it for a low miles clean car; Plus I love black on black. Its not a decal, its some sort of light paint that would need to be wetsanded and buffed out.

Ooo, never mind then. ;)

CustomLowz, now that's what I'm talking about...wide and low...but not too low. Anyone else running 255/35/18...on an I? (pics please) Facing slight dilemma w/my 02 I35. About to throw on some GR-2's and Megan springs (1.8f, 1.6r I think) with 06 M35 18's (haven't seen these used much but they're hot to me). Maxima bodywork is quite sporting compared to I30/35 so its hard to tell if suspension/wheel/tire set-ups translate equally. Seems like many dig the 245/40 but I'd like a little less side-wall with that wide look...of course I'd like the tires to fill the wheel wells also. After calculating it all 265/35 is closest, but that may look silly on 8" rim. Think I'm gonna drive the tire shop crazy trying on 4 or 5 different sizes LOL:D

not bad but imho it would look better if you dropped it a bit.
