Darn, my rear 19" Tires are bald on the inside (about 1.5 inches towards centre of tire)but no wires exposed, would you recommend I get the wheels aligned and then and then hope for the best?do I need to align the front at the same time?and does anyone have the optimum measurements for 19" turnanzas?

I noticed the rear wheels were toed in but thought it normal, pretty dum cos I should have realised that all the traction was being focused on the areas of the tires that is now worn....
