Smaller winter tires??

[freakstatus]

I will be putting winter tires on the MM soon. They are 225/60 R16's all around. I was just wondering how this would affect performance and driveability? Does anyone know how to adjust the speedometer to compensate with an XCal2??
Any help will be great! Thanks.

Thats what I am running on my car for winter tires. they are the same size as the stock fronts. For your 300a all you will need to adjust is the tire revolutions per mile. I will try to look it up in my file and see what I have it set at. I got mine spot on with my 2 gps's.

That's about the size I used back in the day. Before I had 4:10 gears it made the car act as if I had them, and after the gears it made it feel like 3:90's.

Crazy! Took a little getting used to, and avoid the rev limiter on wots.

Otherwise, fine for one winter season with Blizzacks.

I set my revolutions per mile at 781. its pretty darn close. less than 1mph off at 60

How did you do this? Was it with an Xcal2?

No. but still waiting to hear this one....

And without an Xcal what is the difference mphwise??

how do you do it? edit the settings in your xcal for your tune. Or ask your tuner for a .xtr file of your tune so you can load it with Extreme Tune and do it on your PC.

the settings are in there already, you just need to go in and change it
