anytime you alter ride height, tire size, wheel size/offset you need to have the alignment checked. Keeping in mind that stock alignment spec are a starting point and not the end all. I have 2 models of Jaguars at work, 03-07 Stype, and 04-08 XJ8 that if aligned to the original manufacture specs WILL wearout the inside of the front tires due to insufficient toe in. the Stype specs have been changed, the XJ8 have not. I look at what the tires tell me, and then look at the starting point of where the alignment is at and make adjustment based upon experience to correct what I see in tire wear. Now when you increase tire size(diameter) as you have done you alter the pivot point between the ground and suspension, this changes in many cases the alignment, not always but many times. The type tire you also use and many other variables come into play. I have seen(1 example) of a Kumho tire get chewed up inside with the specs(stock) that the Michelins before had no problem with, I increased the toe in for the 2nd set of front tires(Kumho) and they they wore great. So bottom line is dont be penny smart and dollar stupid, have the alignment checked, save the printout in you glove box, and get a tire tread depth tool to measure tread depth(couple $$ at autoparts store) and measure both the inside and outside tread blocks every couple thousand miles, youre looking for NO MORE than a 2/32nds difference between the 2 measurements, if theres more you need to go have the alignment checked and adjusted to FIX the wear ie if there's more wear inside of both fronts=more toe in need. If more wear outside edge wear then decrease toe in.
You have to ask yourself this "whats cheaper $50-90 alignment, or $600-800 for new tires?"
