Been re-thinking this. Since the front wheels are 9 inches wide I don't want to go wider than 265 up front. Now I am leaning towards:

Bridgestone RE-11 265/35/19 front
Nitto NT05 275/35/19 rear

Would like to go 285 in the rear but it would make the diameter front to rear 0.6" difference. I don't think I want to do that.

I don't think it would be wise to mix brands of tires from front to rear. Could cause traction/handling problems.

How so?

The fact that the two tires are different brands would suggest they may have different traction/handling capabilities. One may stick better than another causing one end to break loose sooner than the other. The tires may have different rubber compound and with changing temperatures, one compound may behave differently than another (eg, one gets harder and less sticky at cold temps sooner or may behave differently if driving hard).

You could probably get used to the driving characteristics, but you wouldn't have to worry about any potential differences if it was the same model tire.

Umm, stock tire sizes are very different front to rear anyways. 275's in the rear and 245's up front. Also as long as you get tires of similar performance it is fine. Would be bad to do all seasons up front with Extreme performance summer tires in the rear.

Running 265 extreme performance tires up front and 275 extreme performance tires in the rear will be more balanced than the stock 245/275 setup with max performance summer tires.

Remember....if you change the diameter, it will effect your speedometer........I did this on my 240Z and got stopped by a State Trooper that I knew was following me......and my "actual speed" was faster than what the speedometer was showing.....nice guy tho......he did not give me a ticket......just a thought....

Yup, I am taking that into account with my tire size choice.
