I recently got wider tires and spacers on my wife's GLA45. I started with OEM contis 235/40/20 and 15mm in the rear and 18mm in the front. She needed new tires so I got her 245/40/20 Michelin A/S 3+ and bumped the front spacers down to 15mm.

Rears rub slightly on full compression with the 245/40 and 15mm spacer. They rub on the under inside of the grey fender flare which doesn't bother her all that much. Tires have a slightly taller sidewall and help to fill out the wheel wells and the A/Ss offer a much smoother ride than the Contis. They seem to do great in all conditions and no more skidding at full lock with the stock tires.

Went with H&R DR spacers 15mm from ECS part: 3655665SW:

Got some 64mm bolts from Amazon that fit both 15/18mm spacers: https://www.amazon.com/gp/product/B07R9WYN93/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1

I actually bought 69mm as well but didn't end up using them as the 64mm ones worked fine for both. With stock tires sizes the 18/15 looked better but again with wider tires don't need such wide spacers.

You have 20" rims, what width are they and what offset?

Not sure the spacer is needed, which would stop your rub. I run stock 19" AMG wheels, 245/45/19 and no rub. What is your spec on your tire height, it can't be any taller than mine?

For sure don’t need a spacer but I like wheels to be flush with the fenders on all my cars. They will clear without a spacer. A little rub is ok with me (wife too). 19 is a shorter wheel but a 45 is taller so who knows. All I know is there us less wheel gap with a 240/40 vs 235/40.

I just got the 245/45/19 tires installed yesterday and found they do rub under specific circumstances. For example, the front will rub when I am turning and going up a ramp. I need to reduce my speed more before I turn into a ramp to avoid the rub. It should be fine on a daily usage, but I would worry since I do take the car to the racetrack (I don't feel confident to take the curb anymore)
