I bought a little red Altima Coupe last Friday and decided that I wanted bigger wheels so I had the dealer install some chromed 18" Rims with Toyo’s. (my daughter says it’s a PHAT ride)
They of course did nothing about the 17" donut spare (I traded in my 17’s, they are gone). I could possibly find an 18" donut spare off of a Maxima SE but was wondering if I needed to. What would happen if I ran the 17" donut for a couple of miles? Would it damage the differential gears? I’ve driven on a flat/rim before and that didn’t seem to damage the car (just embarrassing). What if I drove with the 17" for 50 miles, would that be worse than a couple of blocks?
