Advice on Wider Tire Setup

With this information, if someone runs 255/35/19 for fronts, shouldn't one be running something like a 295/30/19 in the rear? I'm running factory size tires on an aftermarket rim...9" front and 10.5" rear... I'm getting CRAZY wear in the front inside of my tires. Alignment is pretty much bang on and I get an alignment every 6 months (life time alignment program). Also running aftermarket lower control arm bushings from FIGS. I bought the FIGS bushings because I thought it would solve my tire wear issue.. I heard that if I went with wider tires in the front, it might improve the contact patch and therefore fix my excessive wear? But if I move the rear tires, currently 255/35/19 to the front....I think running anything other than a 295/30/19 would create a mismatch in the overall tire diameter front vs back....?????????
There are other variables as well if your modded and making over 400whp what type of driving you like to do? autocross, drag racing, DD, roadcousrse? How are road conditions where you live poor like in northeast and Midwest snow belt regions. Urban areas with heavy truck usage that causing ruts or crowning etc on roads. Driving a car with 295 on rear in areas like that will affect handling of car in negative way.
Once again you need to factor all of this when selecting tire size and type. Just because someone is using 285 or 295 rear tire where they live for type of driving that they do doesn't necessarily mean this will be the best tire for your use in your area.
For me my 255/275 S tires setup produces less understeer than my 245/285 A/S setup. My F is DD with occasional track days. Where I live there tons of back roads with some serious twisties on them so for me, I'm more concerned with controlling understeer and handling. But if I DD and lived in Texas, Arizona, Florida, New Mexico etc, place with great, long straight flat roads I would be looking to maximize grip.

No not necessarily if you look at the current RCF and M3/4 tire configurations you'll see they all come with 255/35/19F 275/35/19R setup. Can you go with larger rear tire setup absolutely 285 or even 295. But if your at stock hp going 285 or 295 imo is not necessary just go with stickier rear tire like 275. Mind you I'm FBO well over 400whp 255/275 setup works well for me.
