The Nissan Factory alloys are very sturdy, unlike the massive range of look good street crawler alloy rims or rims developed well before computer FEA was avail. I dont have any concerns about the structural integrity of the factory alloys, however the weight is a valid comment. Do you have a brand or style you know of that are well made? @MB, whats your spin on this - I know you dont like alloys, but what is the brand of steely's you use?
