What must be done after larger wheels and tires have been mounted?

I have just mounted 22" wheels and tires on a 2007 Chrysler 300. The stock wheel is a 17" wheel. I realize the performance and ride quality will diminish, but should I be taking it into the dealership to reconfigure the onboard computer system due to the larger tire diameter? The speedometer and odometer are all controlled by the computer I think... Are there any other steps I should be taking? Thanks.|||we install wheel/tire pkg's daily at the FIRESTONE where I am the service mgr and the most important thing to check is if your combo will turn on the ABS warning light due to a change in tire revolutions per mile,then we check the computer to see if any codes were set because the cars engine mgment sys also monitors these items.sometimes we send our customers to TACOMA speedometer for recalibration-hope this helps|||In addition to speedometer/odometer adjustments, you might consider changes in breaks, since your wheel/tire is much bigger than the original, your braking will suffer dramatically.


It may be worth it to invest in bigger calipers and rotors.|||My first question is why did you do this? For appearance? With that big a change, yes, your performance and ride will suffer, your mileage and speed will not be correctly portrayed, and the car may bottom out in the wheel wells. Is there sufficient room in the wheel wells for the bigger wheel/tire combination? About the speed: be very careful about the speed limits - if you don't get your speedometer changed to indicate the correct speed, you could easily get pulled over for going faster than you think you're going.|||The first thing you might want to do is figure out how much more tire circumference you have with the 22 inch tires. If the tire/wheel exchange was done correctly, you might not need a speedometer correction. Figure out the revolutions per mile of both tire sizes and avoid the speedometer recalibration if the answers are within 5% of 900 REVs/mile. The original speedometer measurements are normally over-optomistic.
