Re: Vote to help me deside!

what about 19x8, with 40mm offset for the front (it will fit without spacer right?) 19x9.5 20mm for the rear with 5mm spacer. 245x35x19 tires upfront and 275x30x19 in the rear?

The tires are too different in diameter to work properly. Also the rear will want about 10mm more backspacing (30) to work

Not going to work. Your fronts are going to stick out 1/2 - 9/16 " . You need a 56mm offset to run those wheels. With a 30mm and a 1" spacer you've got a 5mm backspace

Read what Dave wrote this is where i am getting my info.

I would presonally do 4 18x9.5" with 30mm offset, buy a 1" spacer for the front. Your rear would be ideal the front sunken in less than 5mm ( which less than 1/4") and the ability to rotate your rims.

The larger offset spacers like the one I recommend have a hub that bolt to the factory hub and then use a different set of lugs to attach the rims. I know people who autocross Corvette with those spacers. I am sure it isn't ideal, but our truck aren't even going to come close to the stress of autocrossing Corvette. I would use a straight spacer with longer studs for 3/4" or higher.

Perhaps this will better illustrate what I mean

Your wheels will move OUTWARD 1" , not inward

With 40mm offset (9.5" rim)
Your new wheel will have the following chracteristics:
The clearance from stut housing to the inside of the wheel will be 16mm LESS
The outside edge of the wheel will EXTEND an extra 22mm

with 40mm offset and 1" spacer
Your new wheel will have the following chracteristics:
The clearance from stut housing to the inside of the wheel will be 9mm MORE
The outside edge of the wheel will EXTEND an extra 47mm

19x9.5 30mm with 30mm spacer= Your new wheel will have the following chracteristics:
The clearance from stut housing to the inside of the wheel will be 38mm LESS
The outside edge of the wheel will extend to THE SAME point as the stock wheel
I know i know if i use a 30mm spacer on a 30mm offset it will =0 that being said do i go with a 18x8.5 with 40mm offset?

stock wheels are 16x8 on a 42mm offset up front and a 13mm offset in rear. 18x8.5 will want about a 47mm offset to run flush, but if you can deal with the tires sticking out 3/16" then you can do that
