18's on a accord

[MarioBurke]

mario, the second link is clearly explained and has pics to it. See the second post in that thread. Also lemme just explain.

a positive offset is used for wider rims. this keeps the center of the rim closer to the hub to get more clearance on the inside of the wheel-well to clear the box frame under lock to lock turns.

A negative offset is used for skinnier rims or Deep dish rims, to keep the center of the rim close to the hub. and usually done to non moving axle as in the RWD cars.

The point being of choosing the right amount of offset is to keep the clearance in mind and importantly the center of the wheel closer to the hub, to reduce sprung weight. cause the father the center of the rim (mass center) the greater is the moment arm. and u dont want that.

there is also a solution to use precicly machined wheel spacers. if i am right, u can be able to grab one for 10mm - 15mm aluminum spacers to get the right offset u want. But i for one, dont recommend using that. Just too much weight on the 4 corners.

IMPORTANT: Always keep in mind to use the right size rim for the right size tire.

Jesus SMUF, I read the fucking link!! Goddam, I know i get upset easily but if someone would READ my question and then answer me I wouldnt get upset. (hold on while I go break some shit)

ok....

I read the second link and saw the pictures already, but it did not answer my question. because that link only describes Positive, negative, and center offset, but it did not explain what the numerical offsets were. 38,40,45. so if my rim is considered a positive offset rim, what would that make it? 40, 45 offseet

[smufguy]

but now u get it right?

FOr example, a 13 X 4 size rim can use 185 rubber with 40mm offset, but a 16 X 7 rim which can use a 215 or 225 rubber needs to have 45mm offset or greaterr.

no that still doesnt help me figure out what offset is. I will repeat the question....maybe someone can actually answer it. DOES a 38 offset bring the Center of the rim closer or further away from the hub? IS 38 CLOSER AND 45 FURTHER AWAY?? OR IS 38 FURTHER AND 45 CLOSER?? AGAIN HOW CAN I TELL THE OFFSET OF MY RIM?? I KNOW I NEED TO RUNA 40MM OFFSET, BUT WHY???

Farther out (away from the hub) is positive offset.

The cross section of the wheel below show offset in blue. On the left is a wheel with a larger positive offset around 40 mm. The right wheel has a smaller offset around 15 mm.

mario, you dont seem to understand what the numbers mean. The numbers are the distances between the center of the rim to the mating surface of the hub on the knuckle. I dont know how else to explain this to you when the picture clearly has the centerline of the wheel and the distance pointing to the hub. you want the center of the rim to be close or right on the line of the hub.



using the above picture as an example, lemme tell u something simple. Lets say u wanna run 215 or 225 tires like me. So u choose either 7 or 7.5" wide rims. So with this u choose a 38mm offset rim and a 45mm offset rim. U use the 38mm rim, u will not be able to install it correctly and even if u manage to put it on the hub, under wheel turn, u will rub inside the wheel well. this is because the center of the rim is inside towards the car so there is more rim towards the inside of the car than outside.

On the other hand u use the 45mm rim, u will be correclty installed and under turn u wont rum on the inside of the wheelwell. And u will have the center of the rim pretty close or even right on the axis of the hub which is what u wanna achieve. NOTE: Running this wide of a rim will have u do some fender work and rolling up the fender might just not be enough and it all depends on how much the car is lowered and also how much camber you got.
So a 45mm offset is used for wider rims and 38 for narrower. offset does not push or pull the rim in or out of the fender. Its the number used to CORRECTLY FIT the size of rim whose width is LARGER than stock.

the rim's offset is stamped on the inside mating surface of the it and also is posted on the spec sheet that comes with it or if u go to the main manufacturer website of the rim, they are always listed there or u can all the tech dept and make sure u can get the desired rim in that size.
Get it man?

HOLY SHIT!! THANK YOU MIKE!! couldnt have made it more simple than that.

[MrBen]

Straight and to the point. Doesn't get any better

your info helped but he got the question. so you say, the offset is actually stamped on the rim iteslf?

.....the rim's offset is stamped on the inside mating surface of the it and also is posted on the spec sheet that comes with it or if u go to the main manufacturer website of the rim, they are always listed there or u can all the tech dept and make sure u can get the desired rim in that size......


well I searched the website for quite some time already and i didnt find anything. ADR racing or whatever it is. all they have is the new line of rims. I think this one is a bit older. a year or so. and I got the rims from a friend so i didnt get any paper work from him. if get the chance to call them I will try that. most of the time i just work too much. Next question is you said its also stamped on the inside mating surface?? do you mean I have to demount the tire to check for the offset, or is it visable in plain view?

by the way thanks for being patient. lol

[smufguy]

aftermarket rims are stamped in the back. So yeah u gotta take the rim to look at it. I have seen three aftermarket rims (one on the car and two on the shelf and they had them). stock Alloy rims have it stamped on the outside lip of the rim.

so yeah if you could not find it on the site, give them a call and see if u can find the specs.

No prob man, i thought it was clearly obvious from the pictures, but i guess i did not put myself in your position to look at it. ALways here to help .......... in a very complicated way

[Neuspeed87lx]

yes they will, but you won't have the tire on it. the max rim you can fit and still have enough rubber around it is 17".
next time do the search before asking.

i duuno why u say the max rim you can fit is 17inch and have enough rubber... had an 89 accord with 19s on it .... lowered a bit too .... and never rubbed ....never ....and had plenty of rubber
