Changing the tire aspect ratio... Good or bad?

Whatever rating for load on your CURRENT tires, assuming drives is the rating you get new tire with....

DO NOT put different aspect, if you stack small short 60's with 80's the big 80 is going to feel cheated carrying all the load that the 60 wont do. If you stuck a 80 on with other 60's then that 80 must fail quickly due to too much loading.

Whatever all your drives aspect is at is what you buy. It has to match equally all around.

If not? Then your drives internals will not be happy and start wearing and overheating.

 

The ratio is the height of the sidewalls, 295 is the with of the tire, so 80 means the sidewalls are 80% of 295mm.
So if you get the 80 it's gonna be a little bit higher then the one you have now.
As long as you don't mismatch them on the same axle, you should be fine.

 

You’re buying a whole set? Well, the only thing that should happen is the higher side profile will give you a slightly taller gear ratio. Slightly lower rpm at the same speed...btw, your speedometer may be a bit slow. You will be rolling at a slightly higher speed than what the speedometer shows.

 

I thought he's talking about steer tires!?

 

H rated tires have more plies, hold more pressure, and come with a higher load rating than your G rated tires.

I wouldn't worry about the slight aspect ratio difference as long as you're doing both steer tires.

 

Got it. I was mislead by the ‘what will this change in my drive?’ question. Steers only...no changes.
