Welcome to the site. Thank you for this heads up. I have a Canadian Sport (All American Sport) with aluminum wheels. I lost 1 wheel when it was new due to improper tq. Make sure you re-torqe your lugs 4 or 5 times or untill the stop turning when you retorqe. As far as tires I have Highway Troopers, I had 1 side wall fail and it was replaced under warrenty. I don't know what the rims are rated for, and I can't go look right now. Where did you find this spec? Can you post a pic of your rims?
