So I was wondering what size tires you guys are running on your 17s. This set of wheels I got have 205/40/17 tires and they make the wheels look like 15s. I was thinking about running 225/55/17 so my speedo isnt too far off. My old wheels have 225/60/16 on them. Let me know what size you guys are running. Thanks.

Are you sure you have 225/60. They are not the correct size so you speedo would be off with them. I believe you would have had 205/55=16 as an optional size

Sorry, I forgot to add they are on my Cutlass, not my GA.

Use 215/45-17. This is the best choice when plus-sizing to 17's on a 92-98 chassis.

Your old tires were the wrong size too. They should have been 205/55-16, so technically your speedometer has never been right.

Oh, well then this does not belong in the regular GA sections. Moved.

my 99 grand am has 225 50r16's so does that mean my speedometer is off.

I've got 215/45's on my 17's. I had 215/50's but that caused some rub when I was turning or the front was bouncing.
