BartJJ please take time to fill in your profile for us to help you better. With the auto in the 07, and if you run 35s (with all the items listed above) and regear to 5.13 (the recommendation for an auto with 35s) you will be running high rpms at 85 IMO. You can check the Gear Chart found in the FAQs 85mph is about 20% higher than 70mph so, doing the math you would be turning about 3500 rpms....a tad high for me. Then again I would never drive on 35s at 85....I stick to 75 max in Colorado.

I do not consider myself a smartass. I point out the obvious, search for the truth, and speak fluent sarcasm. I am, by experience, an accomplished curmudgeon.
