I've never done it "Hipari" style. I've put alot of 215/75's on 15x8's for S10's and I hate the look of it. Your tire changer will cuss you because it is a BITCH to get the tire to hold air, let alone bead up. Also you run a higher risk of rolling the tire off the bead if you let your air pressure drop. I'd check the air once a week and probably run max pressure in the tires for safety. This will make them balloon up and you'll wear the centers out of them fast.
I guess thats the price you'll pay to have "Hipari"

Can you say curb rash waiting to happen??
