I would appreciate any advice on where I can get black wheels & on off road tires. The choice is hard for the 18 inch wheels are only on the Limited. Really don't want a lift. Will the Wild peaks work ? Thanks for any help.
If you're going to change Wheels and Tires, No need to stick with the 18"s. You'll find a much better selection of Off Road tires in 17", and 17" rims will fit fine on a limited.
That will depend on your choice of tires, But even going up to the max you easily can without a lift (225x65r17) The change will be pretty small, My Speedo was roughly 3mph off (low) at 70 with that size.
