19.5 tires running mixed brands and ratings
I've got 19.5 (225 70 R19.5) tires on my 2008 GMC 2500. I'm currently running Continental HSR in the front and HDR in the rear. Theses are H load range rated tires. I can get a fantastic deal on 2 Go...

It looks like you are running a 2WD. So, no problem fore to aft with keeping the loaded radius the same. Just keep the same (actual) tire diameter on each side of the axle. Also, remember that the load on the front axle does not change much with the addition of the TC. You seem well over-rated with wheels and tires, so I would put the G rated on the front and the H rated on the rear unless you want a more aggressive tread on the drive axle, then make that choice. It just doesn't matter. On a 2WD, almost every tire installer recommends having the best tires on the rear, for safety reasons. I had this go-round with 2 new tires I bought for my Chrysler 300M and wanted on the front. Costco said they would only mount them on the rear, not the drive axle. They were snow tires. Snow tires don't do much good on the non-drive axle.
The only other consideration is the wheel width. Some 19.5's do better with a narrower wheel; some are built with a wider wheel in mind. It's the way the bead fits to the inside of the rim and why any ".5" tire (16.5, 19.5) tends to walk off the rim at low pressure. Most mfgrs. post a range of recommended wheel widths with their tire stats, whether those wheels are actually available or not.
