Need advice, best tire size for 9.5 front 10.5 rear wheels?

[mediumrare]

Hey guys I plan on ordering a new set of wheels and tires for my 2019 mustang gt pp1 magneride, I am going with vossen hf5 20's and from what I have seen 9.5 front and 10.5 rear should fit perfect for a flush fit, however I am not sure what tire size I need so I need some help. Should I go with a 275 front/295 rear, or 275 front/305 rear? I'd like to go as wide as possible without having to do any modifications and want to have the option to lower the car later without rubbing. I like the sound of 305 rears, would that size on 10.5 wheels create any issues? Do any of these tire sizes require any camber adjustment?

I am completely new to ordering aftermarket wheel/tires sizes and know very little about this topic so any help is appreciated as far as the implications of these sizes, I just want to go as wide as possible without creating any weird issues, the car is a daily driver.
This is the fitment I am referencing:

I got Michelin PS4S in 275 and 295 and there's plenty of rim protection and no stretch. Both were 35 sidewalls. I have heard that different tyres have different sidewalls which can impact rim protection and ride.

EDIT: On 20s in 9.5 and 10.5.

I would say 275/295 is best w those widths. Also eibach springs are the lowest out there so maybe not the most daily driver friendly.

Also since you have 20’s you may have rubbing issues if you go 35 sidewall with eibachs but I’m not certain on that.

shouldn’t need any camber adjustments. What are the wheel offsets?

I am planning on getting Michelin ps4s, the offset according to the manufacturer is +25 front, +45 rear. If I do lower the car it would be the steeda magneride compatible springs which are only 1" lower, not sure how that compares to the eibach's. At what point is a camber adjustment needed? Could I do 305 rear without a camber adjustment?

if you’re set on 305’s I would recommend getting a larger 11” wheel for optimal fit and performance. Otherwise, the 305’s on 10.5 would work just fine with only the slightest amount of bulge. However, a 35 sidewall would be preferred in that case versus a 30 to minimize that.

I don’t believe you’re in the territory of needing a camber adjustment and that’s with the drop.

I just mounted some 305s on my 17X10 drag wheels and they fit perfectly; no ballooning. Here are a few pics for reference.

Have 305/30/20 rear on 10s and 255/35/20 on 8.5s.....obviously not a track car. Lowered on Sportlines, no rubbing, no issues. The 305s on a 10 inch rim do not look funny or bulge etc whatsoever...I will post pics if you would like to see.

sure send a pic if you have a chance, but I would think the rubbing issue would come a combination of a certain offset

I am staggered but I am Front: 19x9.5 275/40/19….Rear: 20x11 305/30/20.
