1QWIK7 on this forum is trying to convince me on offset issue
heres the deal

RIM 1

WIDTH- 9.5
OFFSET- 35-38mm
TIRE SIZE- 265

RIM 2

WIDTH- 9.5
OFFSET- 45mm
TIRE SIZE- 275

hes saying the a stock fd w REAR STOCK FENDERS, will fit better with a lower offset (38mm) RIM 1. i told him no that it will most likely rub the rear quarters. he said no. that that RIM2 WILL RUB MORE.

HERE IS THE AIM CONVO

StReEtDrEaMs5520 (8:39:43 PM): they r nice they will RUB though
TheGuy1224 (8:40:18 PM): nah, i had these offsets before, they didnt rub
TheGuy1224 (8:40:47 PM): remember my car isnt as lowered as yours lol
StReEtDrEaMs5520 (8:41:32 PM): with a streached toire
StReEtDrEaMs5520 (8:41:46 PM): but if u use the recommended 265
StReEtDrEaMs5520 (8:42:03 PM): most likely will rub
TheGuy1224 (8:42:18 PM): in the front or rear?
TheGuy1224 (8:42:32 PM): my 18s i had was a 275 with a 45 offset wheel
StReEtDrEaMs5520 (8:42:34 PM): i had shocks and sprins when i had 9 in rear with 38mm off
TheGuy1224 (8:42:40 PM): that was worse
StReEtDrEaMs5520 (8:42:42 PM): and the rubbed like crazy
TheGuy1224 (8:43:02 PM): a 265 on a 38 offset wheel wont be as bad
StReEtDrEaMs5520 (8:43:04 PM): im talking rear
StReEtDrEaMs5520 (8:43:20 PM): whhat wait ull see
StReEtDrEaMs5520 (8:43:34 PM): i did that was horrible
TheGuy1224 (8:44:06 PM): i had a 275 before on a 45 offset wheel, thats worse than a 265 on a 38
StReEtDrEaMs5520 (8:46:31 PM): in the rear?
TheGuy1224 (8:46:46 PM): yes
StReEtDrEaMs5520 (8:46:52 PM): impossible
StReEtDrEaMs5520 (8:47:03 PM): do u know offett well
StReEtDrEaMs5520 (8:47:04 PM): ?
TheGuy1224 (8:47:10 PM): yes i do
TheGuy1224 (8:47:14 PM): and its not impossible
StReEtDrEaMs5520 (8:47:26 PM): the lower the offset
TheGuy1224 (8:47:32 PM): guys run 285's on their ccw's with a 50 offset and no rubs
StReEtDrEaMs5520 (8:47:47 PM): because 50 ofset
TheGuy1224 (8:48:01 PM): i know that
TheGuy1224 (8:48:05 PM): so a 275 on a 45 isnt bad
StReEtDrEaMs5520 (8:48:18 PM): that 38 will eaat ur fender alive
StReEtDrEaMs5520 (8:48:38 PM): a 275 on 45 is good
TheGuy1224 (8:48:38 PM): lol how if i had a 275 on a 45 offset wheel before?
TheGuy1224 (8:48:41 PM): that was worse
StReEtDrEaMs5520 (8:49:03 PM): a 265 on 38 is bad
StReEtDrEaMs5520 (8:49:19 PM): worse
StReEtDrEaMs5520 (8:49:21 PM): ?
TheGuy1224 (8:49:25 PM): lol a 275 on a 45 is 3mm further out
StReEtDrEaMs5520 (8:49:30 PM): what do u mean by worse
TheGuy1224 (8:49:34 PM): than a 265 on a 38 offset
StReEtDrEaMs5520 (8:49:41 PM): nooooooooooooooooooooooo
StReEtDrEaMs5520 (8:49:48 PM): the lower the offset
StReEtDrEaMs5520 (8:49:57 PM): the FURTHER OUT THE RIM WILLBE
TheGuy1224 (8:50:04 PM): I KNOW lol
StReEtDrEaMs5520 (8:50:05 PM): U HAVE IT WRONG
TheGuy1224 (8:50:15 PM): thats why i said 275, 45 offset is further out
TheGuy1224 (8:50:21 PM): than a 265, 38 offset
TheGuy1224 (8:50:23 PM): think about it wan
StReEtDrEaMs5520 (8:50:46 PM): IM SORRY BUT u have some research to do
TheGuy1224 (8:51:04 PM): wan, 275, 45 offset is the SAME as a 265, 35 offset
StReEtDrEaMs5520 (8:51:04 PM): a 275 on a 45 is further in
TheGuy1224 (8:51:10 PM): wrong
TheGuy1224 (8:51:19 PM): 275 is 10mm wider than an 265
TheGuy1224 (8:51:25 PM): which compensates for offset
StReEtDrEaMs5520 (8:51:35 PM): no it doesnt
TheGuy1224 (8:51:42 PM): LOL omg
StReEtDrEaMs5520 (8:51:43 PM): ima post it up oin forum
TheGuy1224 (8:51:48 PM): why you think people put spacers?
TheGuy1224 (8:51:51 PM): to compensate
StReEtDrEaMs5520 (8:51:51 PM): cause ur not getting me

CAN SOMEONE PLEASE STATE THEIR OPINION
THANKS

Bottom line, for the peopel who wont read the entire aim convo.

ALL IM SAYING.

Is that when i had a 275 tire on a 45 offset wheel, it was WORSE than me running a 265 tire on a 38 offset wheel.

njstreetrx7 is saying its not worse. When in actuality, the 275, 45 offset wheel sticks out 3mm further than the 265, 38 offset wheel setup.

njstreetrx7

38mm sticks out 7mm more than a 45mm
1qwik7 also says that a

TheGuy1224 (9:14:15 PM): 275, 45 offset is the same as 265, 35 offset
StReEtDrEaMs5520 (9:14:30 PM): man u have alot to learn
StReEtDrEaMs5520 (9:14:32 PM): lol
TheGuy1224 (9:14:39 PM): omg lol
TheGuy1224 (9:14:41 PM): ok
TheGuy1224 (9:14:44 PM): i hope im wrong
TheGuy1224 (9:14:50 PM): cause then alot of people are wrong too

WHATTT?

1QWIK7

iTrader: (33)

Wan, you still dont get it.

38mm sticks out 7mm more than a 45 offset OBVIOUSLY.

But when you have a 275 over a 265 tire, thats a "10MM" difference in thickness.

Resulting in 3mm further out. A 265 tire with a 38 offset wheel is still further in than a 275, 45 offset wheel.

LOL cant believe you dont get this.

1QWIK7

iTrader: (33)

To make things simplier.

285 tire, 55 offset
275 tire, 45 offset
265 tire, 35 offset
255 tire, 25 offset
245 tire, 15 offset

They are all gonna result in teh same position when bolted on.

Well children wasn't that fun?

aznpoopy

uh, under the ideal illusory situation that the tire width is like a perfectly flat surface when installed, a tire that is 10mm wider overall will stick out 5mm more on one side and 5mm more on the other. not 10mm out more on one side only.

fitment doesn't really work quite like that. even if it did work the way you are imagining it, it wouldnt be 3mm more outwards. it'd be 2mm less.

1QWIK7

iTrader: (33)

Well thats what i mean, 10mm overall.

But even according to what i said earlier, wouldnt the wheel be in the same position whether you doing a 275, 45 offset or a 265, 35 offset? Like when you mount the wheel to the car, how it sits to the fender, wouldnt it be the same?

Thats the argument at hand.

ptrhahn

iTrader: (9)

Firstly, Rim 2 shouldn't rub. I'm running a 275 on a 10" +42.

In terms of what *actually* sticks out further, that's going to come down to the brand of tire, because not only are different brands different in terms of sidewall profile, they don't always vary the EXACT amount between sizes as the nominal size would suggest.

njstreetrx7

But In General Terms. Which Set Up Would Sit Closer To Fender The 38mm Or 45mm Rim

ptrhahn

iTrader: (9)

Rim #1 will stick out further in +35 or 38 (JUST THE RIM FACE)... the narrower tire may ultimately change the clearance though.

aznpoopy

no, because

shifting offset of the wheel 10mm positive makes the wheel sink 10mm in.
increasing the width of the tire (under that idealized situation) 10mm makes the outboard face of the tire extend only 5mm out.

so 10mm in and then 5mm out = overall change of more clearance by 5mm

in your idealized hypothetical, you'd have to increase the width of the tire 20mm to account for a oppositte change in offset of 10mm. in other words it'd be 275 45 255 35

as for what really happens in the real world, ptrhahn got it

njstreetrx7

thanks guy in general what would be a better fit for fd rim 1 or rim 2?

1QWIK7

iTrader: (33)

Its obvious the 38mm will sit closer but thats not what we were arguing.

I said i had a 275 tire on a 45 offset wheel before which I THINK is worse than me about to run a 265 tire with a 38 offset wheel.

njstreetrx7

tire will NEVER compensate for offset.... it will only compensate for clearance from fender

offset is offset


1qwik7 logic cant work because how will he know at WHAT where the fender lip is. if the fender lip is even with tire at a 45 offset a 38 WILL ONLY MAKE IT WORSE EVEN WITH A 265 TIRE

A RIM WITH A 35 OFFSET WILL NEVER FIT BETTER (CORRECTLY) THAN A RIM WITH A 45 OFFSET

1QWIK7

iTrader: (33)

So then why do they recommend that setup if it will rub against my fender?

What about guys with really LOW offset wheels? They run really narrow tires.

I think tires CAN compensate for offset depending how you calculate it.

After reading aznpoopy's and ptrhahn's posts, my calculations were a bit off.

I should be good with the 265 tire on a 38mm wheel.

1QWIK7

iTrader: (33)

lol thats what we're arguing.

You say a 35 offset will never fit better than a 45 offset wheel. Thats where you compensate for TIRE. Something you said thats impossible.

AND THATS what im arguing.

I know that a 35 offset is worse, cause it comes out further, thats why you then go with a narrow tire.

lol jeez

The problem is, there is no right or wrong. People's ideal's of "fit" differ. If you tell me that you can make a wheel "fit" by running a smaller tire which stretches the sidewall to help with clearance; I'd tell you that's not "fitting". However, that's because my idea of fitting differs from yours.

njstreetrx7

this is a rx7 with a 36 or 37mm offset with a 9.5
this is what u want and look how tire is under lip nd DONT FORGET UR CAR IS LOWERED.....and ur car is lowered
i speak from experience

i had a 9 inch rim in rear b4 my current rims. they had 38 offset with 275 tires fender lip art my tires until i ROLLED MY FENDERS THEN CLEARANCE GOT BETTER.

UR VERY FIRM IN WHAT U BELIEVE SO
CANT BEAT A DEAD HORSE SO IM DONE HERE

IVE BEEN WAITING FOR U TO POST. I AGREE WITH U 100%......I GUESS I HAVE TO RESPECT THE NEXT PERSONS IDEA

7syawedis

iTrader: (1)

i would tend to agree, tires can make or break it when it comes to fitting. 5mm difference in offset isnt going to make quite as much of a difference than the 10mm of tire width. also there will be just a slight sidewall difference in addition to width as they get wider. unless you went from a 265/40 to a 275/35.

i dont know why but as for rolling, do it! especially people who panic about fitment. you really do get a lot of clearance out of it and its not that big of a deal to do so i never saw what the problem is. you could fit either of the mentioned tire and offset combos with a roll just fine.

1QWIK7

iTrader: (33)

I am very firm in what i believe because a professional wheel site is recommending a 265 tire on their 38 offset wheel. Its their recommended package. Its not like i asked for this cause i want it to look the way i want it.

My car is lowered yes but remember its not as low as yours. You even told me my car sits high when i had those 18s on before remember?

The pic you showed me, what width tire he's running?

Either way, when i get these wheels, im gonna take a pic and show you its NOT an issue with rubbing.
