Here are a few opinions for consideration.

If you're getting the 15 inch wheels with more than a 400 HP engine I'd seriously get a set of Mickey Thompson ET Street drag radials in the 275/60 15. The tires don't throw stones under normal driving conditions, they stick like glue and handle much better than the BFG radial TAs. Stay way back from cars in front of you and particularly when cars in front change lanes over the dividing lines which contain a great majority of road debris. Wet weather driving is like sand blasting your paint, so if you can avoid it that's good too. You'll keep the paint chip count down.

Your new TKO 600 trans will seem stiff at first. Break it in for 500 miles by not doing any higher RPM and make slow easy shifts. The trans will last much longer and work better after break in to shift like butter. Warm your engine carefully and drive it easy for break in too. Your car will be faster and smoother if you do these things. Resist high performance driving for 500 miles.

By the time you break in the car in Arizona's hot summer you'll be ready for the cooler winter. Your carb jetting will be up one size for winter starting after when days dip in the 80Fs. The car will be quite a bit faster in winter. Keep the wheel straight ahead before you mash the gas and you'll probably be ok. If it get's loose the Superformance corrects itself pretty good. Save room for stopping too. You'll be going really fast in just a few seconds.

You'll be fine.
