When you say sub40, what exactly does that mean? Is the 40 combined total of both wheels? In other words, referring to 20mm each side? Sorry, I'm new to the slang and lingo. So maybe 15mm is the way to go? I'd be open to rolling the rear fenders. What would you recommend on the front, 5mm or 10mm? thanks.
I wouldn't go below et40 (sub40), but that's just me. Best for you to try fitting spacers. Start w/ 5mm & go thicker til you get the stance you desire.

Im thinking of getting either

18x9.5 et45 with 215/45/18 using stock suspension
or
18x9 et 35 with 215/45/18 using stock suspension.

Will I encounter rub during full load?
Any gurus please advice.
Thanks in advance

On stock suspension, you'll be fine.

Sorry to disappoint you but you will definitely rub with both 18x9.5 et45 and 18x9 et35.

Just showing you an example with 18x9 et35 with 3 adults in the car (which is like 60% of full load). It needed at least 18mm (0.7 inch) additional clearence in order not to rub. Even with 18x9.5 et45 (which is 6.35mm less poke) you would need additional 11.65mm (0.46 inch) clearance compared to 18x9 et35.

For that you'll need an aftermarket control arms and roll the fenders to properly fit it, or just roll the fenders A LOT in the rear or go for hellaflush. Conclusion: you cannot just fit them without additional modifications. According to my heavy calculations and tests with everything stock you can safely go at most with 18x8 et40 or 18x8.5 et45 or 18x9 et50. If you're alone in the car or only 2 adults on the front seats you would probably not rub with anything, but you asked about full load and my calculations are done considering the shock absorber goes 80% of the travel, and with full load it would go so far or even more on curves or speed bumps or bumpy roads.

Up front, some makes & models share common camber bolts...but front camber plates & rear camber arms are model specific.

You appear to have left out a very important piece of information. What size tires you are on. Those appear to be SUV equipment tires. No kidding they roll rub.

Put proper tire sizes on, and you'll be fine.

But hey, what do I know?

18x7.5 et48 won't rub.
Sg roads are perfect to go 19s. RPF1s tend to look smaller than they are. The 19s will look perfect. 19x8 et48 19lbs wrapped w/ 225/40/19s. Absolutely no rub.:)

Are you kidding me? The specific tires in the picture are Hankook Ventus V12 evo2 - 225/45R18 and the only difference in rubbing between these and Toyo's T1R 215/45R18 and Continental ContiSportContact 3 - 225/40R18 was 1 adult. So all of these did rub with 18x9 et35. I'm not sure what's unclear?

Do they still look to you as SUV tires?
