Ok on your tires I would buy what fits your driving habbits. If that is more of an all season tire then go with it. If you drive hard and corner hard then be honest with yourself and go that route. Now I have alway's used a good allseason tire on my wifes jeep and then have them siped for better traction and cooling makes the tires last longer too. If a larger tire in width or and in height is how you to get the tire that best suits your driving and driving habits then go with it. If you do go with a bigger tire then get back to me and I will see if there is a simple way to recalibrate you speedometer. Thanks and good day.

Ok if you want to replace the rims then the tire place should know what fit and will not interfer with the brake calipers and such. I would replace the rims only if the tread width is larger then the rim width you have now. Meaning for example if you buy a tire with an 8 inche tread pattern and you wheels have a 6 inch width then yes I would replace the rims to get as much contact to the road that I can. Is that more of what you were looking for? If not then get back to me with what you are realling wanting to know and I will try to better answer. Now if you go with the bigger tire find out if the height is much different and if it is then get back to me on that too and I will try to get you the calibration procedure so you speedo will be acurate. Thanks again.
