1st timer

Just put on my wheels today and went for a ride with a friend and as soon as I went over medium size bumps the back wheels rub slightly and i'm on stock springs!!!
Gonna be dropping the back by .5" so it's gonna be rubbing alot more when dropped. What do you guys use to cut tabs?

How wide are your rims?

1st timer

7.5" wide.

Pics?

z3Ro

eh...that shouldnt rub...

jjashaa

iTrader: (23)

try going 225-45-17 or maybe even 225-40-17

i think 50 is a bit too thick.

1st timer

because 45-17 or 40-17 would affect the spedo.

^^ what he said, he would need 50 for a close ratio for speedo...thats weird that ur rubbing with that set up.....dremmel or a garden shear can cut the tabs....is it rubbing on the tabs only?

1st timer

It rubs very little,if I had an offset of 50-55,would've been perfect,gonna have to dremel the tabs a bit,no more than 1/4".

01tl4tl

dremel and then sand a nice edge on the cut
If it warms up a bit this weekend, I need to redo mine and roll the fender edge

I used a dremmel, but that setup shouldn't rub. hmm.

1st timer

You can see where it rubs,hopefully it won't rub more when I drop it.

No spacers, that sure doesn't look like 48 offset.

1st timer

That's what i thought, to answer your question,no spacers.

www.tirerack.com has a speedo calibration page- enter old and new tire size and it tells you how much the speedo change is
On my 01, going to bigger diameter rim with lower profile tire came out almost the same distance around the tire rotation, and corrected the slightly fast reading of my speedo!
many gen2 had a 5% fast speedo- has anyone checked their gen3 for actual mileage with a handheld gps compared to the speedo-odometer?

LeeDan00

i seriously can't see why that would rub...

1st timer

maybe my shocks are finished.

Lawaia

Hard to believe those are +48 offset based on those pics. Measure them yourself to be sure they are indeed what was advertised.

try 210-50-17

bibledriver

You sure they are 7.5 not 8.0?

bibledriver

not even an available tire size. if you jump to 225/45 you will lose a bit of sidewall height. I had them last set of tires. The sidewall was so small on the rim that I saw the GAP bigger ( no drop ) It took some getting used to.

1st timer

how do you measure offset?

Aman

how fast do you go over bumps? I can see how it kinda rubs though, the wheel is sticking out just a tiny bit, but enough to rub.

I thought with a +48 the wheel would be just a tiny bit tucked in

1st timer

stock 205/60/16
Stock tire width is 8.070
Stock tire thickness is 4.842
Stock tire diameter is 25.685

new size 225/50/17
New tire width is 8.858
New tire thickness is 4.429
New tire diameter is 25.858
When the speedo indicates 100KM/H,the actual speed is 100.67

02type-s

The tires look a little big. I would have gone with a 215

Calculating the offset of a wheel is a fairly easy mathematical equation. First, measure the overall width of the wheel (remember, just because a wheel is 18x7.5, does not mean that the OVERALL width is 7.5”. It means that the measurement between the outboard flange and the inboard flange is 7.5”). Next, divide that width of the wheel by two; this will give you the centerline of the wheel.


Overall width/2 = Centerline


After determining the centerline, measure from the hub-mounting surface of the hub to the edge of the inboard flange (if the wheel were laying flat on the ground – face up – your measurement would be from the ground to the hub-mounting surface). This is your back spacing.


Back Spacing - Centerline = Offset in Inches


Inches x 25.4 = Offset in mm

No way they are 18x7.5 + 48

Take the wheel off and look for stamps on the inside of the rim that say +48 7.5jj etc.

yea, just by the pic showing the front and rear, the dimensions of the wheel u told us looks way off

After determining the centerline, measure from the mounting pad to the edge of the inboard flange (if the wheel were laying flat on the ground – face up – your measurement would be from the ground to the mounting pad). This is your back spacing.

Centerline – Back Spacing = Offset in Inches

(Inches x 25.4 = Offset in mm)

fahoumh

Uh, yeah...that's what I already posted. And it should be Back Spacing - Centerline.

00 acura tl

im sure the its not +48 offset. try going with 215 50 17, cause the front rim is sticking out no?

Edward'TLS

Just trim off the plastic bumper wherever you see rub marks.

1st timer

I checked the back of the rim and I saw the 17x7.5 stamp,I contacted the supplier and he says it's indeed +48 offset.

1st timer

That's what i'll do.

1st timer

Yeah the front is sticking out a bit but I just got these tires and I can't get other ones!!Gives the car a wider stance wich I kinda like

bibledriver

Crazy. just trim tab like Edward said, sure looks like a 8" w/45 offset (that is what I'm running). I trimmed my tabs and no problems.

Edward'TLS

Judging from the pictures, there is no way that the rims (17x7.5) have a +48 offset. They look like a +42 to +45 to me. The supplier may not even realize what the shipping department has shipped to you. All they do is reading back to you the ordering info from your order form.

Usually the offset number is also stamped with the size info at the back of the rim. Do you see any numbers with "ET" next to it ? This is the offset number, and it won't lie to you about the true offset of the rim.

1st timer

did not look for the offset,will do on the weekend.

1st timer

trimmed the tabs today and there's no rubbing,I had to trim about 1/8".
