Tire Size Question on stock 19" rims

Hi, my front tires require replacement and had a question on them.

Currently the front has 225/35/19 on 19x7.5 wheel which is stock.
The rear has 245/35/19 on 19x8 wheel...
The stock rear size is 245/30/19 but when my rears got busted, I couldn't source anything but only had to increase the profile...

So the question is... can I change my front tires to 225/40/19 and get away with it?
This would be 1.1% longer diameter compared to the rears, which I think I should be fine.

For those who wonder how I survived on 225/35/19 front and 245/35/19, I've been on xDelete so that I don't destroy my transfer case.


In a summary:
Current setup: 225/35/19 front and 245/35/19 rear
Stock setup: 225/35/19 front and 245/30/19 rear
Can I increase my front tire's profile to 225/40/19 and get away with it?

Clearance wise, this should work. I run 225/45-18 winter tyres compared with the stock 225/40-18 without any rubbing. From a speedometer perspective, you probably already have seen the larger rear tyres have changed the speed shown from above the actual speed for stock tyres to slightly below for the larger ones.
