225-50-17 +48offset rubs!!!
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?

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

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?

Something is missing...my
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.

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

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

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

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

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

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.
