Default What tire size? 19x8.5 19x10

I putting some wheels on my SC and its lowered on MKIV eibach springs w/ koni yellow shocks. The wheels are frt:19x8.5" rear: 19x10". What tires sizes should i go with, i will be getting the fenderes rolled and maybe pulled. the offset of the wheels are unknown..i was told maybe 27mm on the front and maybe 19mm on the rear....I want to run the least amount of negative camber as possible. I was thinking 245/35/19 and 285/30/19. Here are some quick pics...

Wheels:
19x8.5 +25mm
19x10+30mm /+35mm

245's up front should be good but the rear 285 with +19 might be a bit much. 265/30/19 BFG KDW's should be fine. You will need to run a little stretch with that offset out back.

i really dont want to try the stretched tire thing. So 275 would be right in between???. How can i figure out the offset?

I would measure the offsets before you do anything. I would avoid going lower than a 275 if you can fit it.

You need to first get your backspace measurement (mounting flange to outer most part of inner wheel lip). Place your wheel face down first on a soft surface. Lay a straight edge across the diameter of the wheel. Measure from mounting flange to straight edge = backspace.

Then find the center line of your wheel (wheel width divided in half). The difference between your backspace and center line measurements will be your offset.

In general, you add 1 inch to the overall width of a wheel to account for outer lips. Wheel widths are measured by inner lip to inner lip; therefore the difference in width specs.

Your 10" wheel will be roughly 11".

Example:

Backspace - 6.5 inch
Centerline - 5.5 inch
Difference - 1 inch = 25.4mm
The difference will be your offset ~ 25/26mm.

If your backspace is greater than your center line = positive offset.
Backspace less than your center line = negative offset.
Backspace equals your center line = 0 offset.

With that kind of offset fitting 285's on the rear (which imo is ideal for a 10" wheel) would be hard. You would definitely without a doubt need a roll at the very least.

i doubt those offsets are what you were told, the lips are too small lol,

they look more like in the 30 range, as for your question, are u looking for most traction or looks?

Those wheels in a 30 range offset should fit 285s perfectly, 295 possibly
