Have you changed your gearing to match the tire size? Is she auto or manual? Other chages/repairs recently? (since bigger tires) Need some background here..

Ummm...exactly what you're getting now. Sticking mongo tires (larger overall diameter) on your ride and *not* regearing the rear axle will effectively raise your final drive ratio....this in turn will make your once half spritely XJ turn into a stone. Raisng the final drive ratio means the engine is working against taller gears. You will also screw up your speedo; it will read lower than what you're actually doing...so beware the speed traps. You're mileage (MPG), which is not a strong suit of the XJ to begin with, will really fall into the crapper. Regearing the rear end is a little tricky; it requires care, skill and patience to do it right so make sure whoever is gonna do it does this sort of thing often.

With 32s and stock gearing, some people just never use the D position in their automatic. They just drive it in 3.

Or you could manually shift it. Which is what I would do.
