Default Staggered wheel combos? Tire sizes?

Whats up Lexus fam, ive got michelin ps4s on my 350 at the moment (on 18in. Enkei’s), great tires, only thing is i regret is getting the same staggered tire sizes as what comes stock on the IS (225 front, 255 rear)
My front tires arent as beefy as the rear and it makes the front wheels look small.
I was thinking of doing 255’s all around (255/35ZR-18)
or maybe beefing up my rear wheels to a 265/275 and moving the 255’s up front.

What do you guys think? I want to stay on 18’s, 19’s are too big for my preference

thanks in advance!!

What are your wheel specs, and are you lowered on anything?

Fronts run 18x8
rear 18x8.5

No suspension mods yet, coilovers def in the future but not planning to stance at all. Only to level the car out bc stock suspension has the front raised higher, and for better handling ofc

You basically have factory size wheels and tires. I don't think wider tire will make your wheels look bigger I would keep those tire widths, and if you can upgrade the wheels to 19x9 and 19x9.5. Generally most people want smaller tires to make the wheels pop and provide better clearance.

I think i just need a different size in terms of the sidewalls for the front, and lower suspension to get rid of that nasty gap

The largest tire size I can get w/o rubbing is 225/50/18 front and 255/45/50 rear (car is not lowered or modded in any way). One size bigger and it rubs, especially if you have other people in the car. The ride is much smoother, mpg remains the same, and my clearance is 1.5 inches higher from the ground, which works great given the potholes and snow we get.

As an aside, I've never owned snow tires (live in PA), so a good set of all seasons has worked for the last 20+ years.

Honestly it sounds to me like you just need a drop. I'd use caution in increasing the overall tire diameter/aspect ratio of the tire, since this can make the speedometer wrong and reduce fuel economy and braking performance. Some on here, like ShrinkDoc, have been able to get away with increasing tire diameter, but it's not something you would want to do unless you have a good reason.
