is it 35mm offset the smallest before the wheels stick past the fender? or was it 38?

 

I hear 30mm. The G35 and Q45 rims that have 30mm offset supposedly fit without sticking out. At least that's what George said...

 

I have a set of 17X8 SSR Integrals with an offset of 32mm. Even at 32mm, they barely clear my Brembo GT kit (I blame it on the spoke design). I previously had a set of 17X8 GS400 wheels with an offset of 50mm and they cleared with a little washer around each wheel stud. At 32mm, the wheels do look like they stick out more, but it's nothing overdone. I like the look, especially with a front lip. I can take a pic if you like.

 

yes, take a pic.

 

pic especially the rears

 

I have 37 on an 8.5" wheel. I put on 5mm rear spacers and it rubbed like hell. I promptly took them off.

Also, 4th gens are different than 5th gens in this department if I am not mistaken....

 

I have 35mm on an 8" wheel with no problems rubbing. I also have Teins/GR2's

 

The offset will depend on the width of the rim. Can't talk about one without the other.

 

i think it's 34mm but i agree with Maximan you have to consider the width. you also have to keep in mind if the wheel is flat or does it have a deep lip to it.

i have 19x8 with 35mm offset and don't rub at all.

the biggest i seen was on the rear has been 18x10 on a 4th gen & i think some here has it done on a 5th gen but i think it was 20x10

 

I've got 17x7.5" Q45 wheels on my 4th gen, and I believe they are 32mm offset. They stick out maybe 3mm, just barely noticible. I'll take some pics today if I get out of work with some daylight left.

 

How bout a 18x7.5 wheel with 42mm offset?? (235/40/18)

 

Offset is 100% independant of rim width.

It just doesn't tell you how far it will stick out of the wheelwell unless you know the wheel width. Offset is measured in relation to the center of the wheel. Backspacing is probably what you are thinking of.

A 6" wide wheel and an 8" wide wheel can both have identical offsets, but the 8" one will stick out of the wheelwell 1" further and also intrude 1" deeper on the other side also.

the best thing for you to do is try the wheel on the car.

 

He is trying to say that how far it sticks out is dependent on BOTH wheel width AND offset. You are both correct.

 

all i'm saying is if you don't know about the wheel size or the offset or the lug pattern all you have to do is try 1 on.

if it don't stick out and it don't rub then your good if it does then don't buy them.

 

Hard to do when buying new or ordering online.

 

How are you supposed to check for rubbing with the car up on a lift? The suspension will be at full extension and you won't be able to see how it looks at rest or fully compressed....

Us 3rd Gen guys have this allowable offset and width thing down pretty pat, surely there must be similar info available for 4th and 5th Gens that you could at least use to extrapolate a guess from.

 

well i wonder how ppl now if 18x10 fit a 4th gen or how 21's fit a G35 and so on. the best thing to do is trying them on the car. it's stated on top that a 4th gen could use 45 to 34mm with out stickig out of the wheel wells but you have to keep in mind that the width of the wheel and style matters.

most aftermarket wheels that are 17x7 or 18x7.5 or 19x8 with a high offset of 45 is made for acuras, civics, accords and other cars that don't have big wheel wells.

most aftermarket wheels for front wheel drive cars come in 45, 40, 38mm offset.

most oem wheels have 40, 45, 50mm and sometimes higher because they come in 6" or 6.5" or 7" width (in other words the wheels are skinny just like our oem wheels).

for those that want to push out the wheels out more so the wheels are almost flush with the wheels wells use a lower offset 38, 35 or 34mm. any thing lower than 33mm might rub. most of all the 35 or 34mm offset wheels are 8" in width or more.

but with all this info you still have to consider if the wheel is flat or does it have a deep lip. you also have to consider the tire size.

for those of you that don't know about wheels, tires, offset, lug pattern go shop around, it's better than ordering wheels and paying for shipping and than the wheels don't fit.

a good place will make sure that every thing fits and nothing rubs before you even pay for them.

out of all the wheels i had only 2 set was order direct from the company and those where weld racing wheels & my axis hagens. i was told that i was the 1st to have 19" chrome hagens in 35mm offset on the east-coast. i took a chance and waited 5 weeks for my wheels not even axis knew if they where going to fit. what helped me was that i have been doing this for over 14yrs.

my next thing is to find out if a 255/35/19 will fit on the rear of my car and how will i do that? BY TRYING THEM ON and taking the car off the lift.

 

Isn't there the possibility that the combo fits fine on the ground and driving slowly, but will start rubbing when you start pushing things though? I remember reading some stories of things like that happening when people start experimenting with unusual combos outside the normal "accepted" range.

What I meant above was that surely someone must have documented the "ultimate" setup already to get the widest tire on a certain wheel width with a certain offset. Then you could use that info to at least "guestimate" whether or not combo-X would fit or not from how its dimensions compare. No?


Oh yes, a few months ago I also learned that a tire's section width changes 0.2" with every 1/2" of change in the wheel width. Might help in those really tight fitments.

 

The springs you are running also come into play.
