Help Please ? OK I FOUND A NEW WHEEL ! MOUNTED A TIRE ON IT, HAD IT BALANCED TOO. PUT IT BEHIND THE DRIVERS SEAT (PASSENGER SEAT FOLDED BACK. WENT ON HOLIDAY. ALL WENT WELL !i have a 2004 Toyota Sienna XLE LTD AWD It came with RUN FLAT 225-60-R17 99H Tires. NO SPARE , but a jack ! I am trying to find a wheel for a full size spare tire that I have saved for the van. When I had two new ones put on the front . I found a black plain 17 " rim, 7 " wide, 5 hole bolt pattern, 4.5 " Pitch circle diam., offset 35 mm, backspace 5.38 ", Bore Diam. 72 mm. Does anyone know what this all means and will it fit my Van ? They say yes, but some buyers warn against their judgement. What to do ? Buy it and have my tire put on it or ? Thanks. I need to do this for our vacation trip soon.
