If I go from the stock 33's on the Adventure Pkg to 35's, how will this affect the all-wheel/4 wheel drive, speedometer, etc (if at all)?

According to the tire calculator I use going from 33" to 35" tires you be going 5% faster than the speedo shows and 7% from the stock 32"tires to 35" tires. Steve

I thought the same thing but i test mine on radar and those street signs telling you how fast your going my speedo read the same as those.
Then i tested it with another car to see if the sign where right.

why would you be going faster the bigger the tire you should be going slower.

Hmmm, I think that I'll respectfully disagree with this; the larger the tire (greater diameter), the more ground that will be covered by one rotation of the axle. If you have two same sized rims that are spinning at the same rpm, one is a 33" and the other is a 35", the 35 will be covering more ground. Hence, faster. (I'm not trying to patronize here)

I think you guys are talking about the same thing.

The speedometer will report slower than the vehicle is moving.

The vehicle will be moving faster than the speedometer is reporting.

according to my gps, my speedo is off by 7 mph with the 35's, but I also went from 32's to 35's, I'd say you would be off around 5 mph.....BUT...this is the all time best method of getting out of 10 mph over the limit speeding tickets...officer I just put the tires on, my speedo said I was going 4 mph over the limt...not 15!!! I have gotten out of 5 tickets so far with my lifted trucks using this line

BTW, I was talking to a guy with an h3 the other night he had 35's, 3 turns on the t-bar and has put on close to 30,000 miles with it like this. He has had NO problems at all with anything.

Just a thought..But if you get your PCM tuned by Alvin (PCM for less) I think they can program the size of tires you're using to callibrate the speedo for you...
