[b3master]

the guy i baught this car from had 225 60 16 all arround now i wanna change the tires, maybe 245 50 16, but my fear is i dont want the car to get more sluggish take off. right now it takes off nicly but 2nd gear hardly gets to 60 mph (like its gonna explode) but with taller tires i think it will get there easier; but i dont want it to feel sluggish... would it?

You are talking about a 1 inch difference in diameter. You will probably not even notice the difference. I'd be surprised if you did. The 245 50 is a lower profile. You'll actually get more leverage against the tire than the 225 60.

What year car? What engine? What transmission? What rear axle gears? Really hard to answer your question without that basic info.

A 225/60-16 has a 26.6" outside diameter, and is actaully larger in diameter than the 245/50-16, which is 25.6" diameter. The smaller diameter 245/50 will have the effect of increasing torque at the rear wheels by almost 4%. It will also cause your speedo to read almost 4% higher than actual speed, if the computer is programmed for the 225/60's.
