so, I've looked for a while and haven't seen a definitive straight forward thread on solving this issue. i want smaller rims 15' or 16' id rather have 16' but im warming up to the 15s'. does one or the other have an order of magnitude difference in price/selection or tires? im exited about the prospect of getting super cheap name brand ultra high performance summers (extreme contacts, ps4s, etc.) what's the official replacement size for either to just maintain the overall wheel size as much as possible? i suppose i could go a little wider if they were cheaper. i looked around and couldn't see a huge difference in price but i definitely could in selection but don't have an official size to look for.
