245/35-19 f
275/35-19 r

Depending on if you're lowered or not, you could go as high as 255/285 on 8.5/9.5 but you shouldn't, a little close to the upper range limit using 120% tire-to-wheel guidelines and you might have to roll the rear fender lips.

Look at the following tire height vis a vis OE ref size.

225 45% 18 25.97 Stock Reference Size
245 45% 18 26.68 Stock Reference Size

Suggested FRONT alternates - 19" Wheels
245 35% 19 25.75
255 35% 19 26.03

Suggested REAR alternates - 19" Wheels
275 35% 19 26.58
285 35% 19 26.85

Now compare with what you suggested.
Front 245 40% 19 26.72 +0.75" taller in front
Rear 275 35% 19 26.58 -0.10 negligible difference

As iideadeyeii said, difference in wheel speeds (from what ECU is expecting) will trigger VDC (if applicable) and/or TCS. If you have neither, you can run your combination but looks might be off a bit.

How is a 245/35 any different in width from a 245/40?? The aspect ratio is the descriptor for tire sidewall height (and overall diameter obviously). Width is width regardless of wheel size.

Annnnnnnd, the front and rear are NOT supposed to be the same height! Wheel speed sensors are set to measure the wheel speeds based on the factory staggered tire heights front and rear; and is expecting ~3% +/- ~0.3% delta, else it interprets a higher rear wheel speed (in your scenario) as rear wheel spin.

Get wider tires if you want a meatier look. If aesthetics is important you could go wider and look in the fat tire thread.

Otherwise I'd listen to the other bros who have already spoken.

Do what MicVelo said and call it a day bro. Again you didn't answer whether or not you are lowered because that changes the conversation
