performance difference

you all know the factory tire size is 205/50/16 for the stock 16" rim. well i have a big question as to how much of a performance difference there is between stock and 205/55/16. performance as in power/acceleration, handling, and stopping?

Any differences would be a result of the manufacturer, tread pattern, tread compound, all season or not, etc. If you are speaking of the exact same tire but 55 series as compared to 50 then the differences will be little or none.

Actually, that's almost an inch (0.87") difference in diameter per this calculator...>>>Clicky
Yes, that will affect acceleration (you're going to be slower) by a measurable amount,
but I'm not sure of the exact numbers.
Same thing with handling, as that's almost a 1/2" taller sidewall.

What's your reasoning for going with the taller profile?
That size will certainly fit, and the ride will be smoother, I'm just curious.

You won't "lose" HP or TQ.

"When changing tire sizes, we recommend staying within 3% of the diameter of the original tire. Any more than this and you face the risk of brake failure."

Wow... never heard that before.

^^^Yep^^^
Bigger diameter = more rolling inertia to stop.
Though, a lighter wheel would certainly help the situation.
