If my calculations are correct then the new -19 should be perfect. The numbers you are using are offset numbers, not backspacing. They don’t mean anything to most people, FYI. Backspacing is
the measurement in inches from the rear wheel mounting surface to a straightedge across the rear outside edge of the wheel.

What is the backspacing on a stock Jeep TJ wheel?
Factory Wrangler wheels are 17′′ diameter x 7′′ wide with
6.25′′

What is Jeep backspacing?
Backspacing is a little bit easier to explain, it’s
the measurement of the mounting face to the back edge of the wheel (inner lip)
. This measurement has a direct influence on whether or not the back of the wheel will make contact with the inner components of the Jeep (shocks, sway bar links, inner fenders, etc.).

What is the biggest size tire you can put on a stock Jeep Wrangler?
The largest tire you can fit on a stock Jeep Wrangler without lifting it is generally
33 inches
. However, keep in mind that, depending on the Wrangler model, a 33-inch tire may not function ideally, and it could do damage to your rig if you take it off-road.
How big of wheels can I put on my Jeep?
Depending on the model you have, most Jeeps need lifts for tires that are
33” or larger
. But, this doesn’t mean that your stock Jeep Wrangler Unlimited will be okay with 32” tires. If the tires are too wide, they will rub against the fenders.
What offset do I need for tires to stick out?
To have the inner portion of the 295 mm wide tire run in about the same location as the 265 mm wide tire did, the wider 8.5 inch wheel would need to have an offset of
-15 mm
. This would make the outer edge of the 295 mm wide tire stick out 30 mm (1.18 inches) more than the 265 mm wide tire.
What does 4 inch backspacing mean?
Here’s an explanation of what backspace and offset mean. Backspace is the distance from a wheel’s mounting surface to the back edge of the wheel in inches. By “back” we mean the brake side of the wheel. … Conversely, a 4-inch backspace would
make the offset negative
.
How much offset is a 2 inch spacer?
So for example, if you are using 2 inch wheel spacers on stock wheels with 60 mm offset, that will give you
+ 9 mm offset
(60 – 25.4 x 2 = 9.2).
Can you put 33 inch tires on 17 inch rims?
33
–
inch tires
work well with
rims
that measure 15 or 16
inches
in width, while 35-
inch tires
should only be used with
rims
that are at least
17
–
inches
wide. Larger
tires
require wider
rims
to maximize the tire profile and improve your Jeep’s maneuverability.
Will all Jeep rims fit all Jeeps?
Jeep Wrangler wheels are interchangeable with many other Jeep vehicles
. There’s also a lot of Wrangler wheel cross-compatibility between generations.
Is 10mm offset a big difference?
10mm isn’t a huge amount
. On some cars it makes little difference. Tough you say. But if you want exact fit…see if the dealer still make it right.
What sticks out more positive or negative offset?
Positive offset creates more backspace
, while negative offset reduces backspace. The example shown here is 6 inches wide with a 3 inch backspacing. This would be the equivalent to a zero offset wheels since the mounting surface aligns with the centerline of the wheel.
Is positive or negative offset better?
As a general rule of thumb,
most front wheel drive vehicles have a positive offset
. If you want to put wider wheels on your vehicle than OEM, you generally need to reduce the offset. By reducing the offset, you bring the wheel a bit more inward, so it doesn’t extend out too far and muck up the way the vehicle handles.
