tire size verses performance

i have a stock 1990 f150 4X4 larait with the big six. id like to level the truck and put 31/10.50s on it. how is this going to affect the performance. only mods ive done to the truc is a K&N filter. by the way, the truck has 106,000 miles on it, doesnt use any oil, and runs great.

The taller the tire, the more gutless it will feel,,, it will raise your gear ratio.

tire size verses performance

I have a 92 Ranger 4.0 V6, I put a 3'' body lift on and took off the 28'' tires to put 31 x 10.5 on. Didn't affect my lowend much, but instead of being able to go 120 on the highway is was cut down to 90... And I belive it has been putting more wear on my clutch, not sure how it would affect an automatic.

Your truck came stock with a 28.9" tire, we're only talking 2", it's not going to affect the gearing very much, the big six can handle it no problem. I put 32s on mine with little effect.

If you can, sure. That's what I did when I didn't have FTE. Buddy of mine has 32's on his bronco and I took two off and put them on the rear of my other truck to see what the gearing would be like.
