Thoughts on a potential new wheel setup

Hey Guys
Considering purchasing some 18 x 9 Methods that are +18 offset. Currently have a 2.5" level up front and running 275/70/18's with 1.25" spidertrax spacers. How far will these poke out past the fender without the spacers? Any chance I could still run the spacers? I have bushwhackers that will be here the beginning of next week so I want them just inside the flares.

Also, whats everyone experience with the TPMS? I thought I read somewhere that the stock ones cant be used on aftermarket wheels? Is this true? I've always just swapped em over. Thanks!

 

Here are a couple of pictures from some years ago when I still had stock tires on. The wheels are 18x9, 18 mm offset and tires are 275/65/18. I have pocket style Bushwacker fender flares on.

The right side is almost flush and left side is a little tucked in.

 

Here are some comparison shots with 295/70/18 on on the same wheels.

You could see here the left side is basically flush and the right side pokes out a tiny bit.
