I have no idea what offset once you go that width...If you don't mind me asking, what power are you putting down to want wheels that wide?

Umm isnt 205's for a 15x7 cause I really dont think thats going to be to safe at all. You might want to step up to maybe a 235 at the smallest and then I still think that might be unsafe. Now im not a tire guy so I could be wrong but yea I dont think you can stretch a tire 5" and still be safe.

You'd probably have to get into negative offsets, and wiiiiiiiiiiiiiiiiidebody. Don't do it for just 300hp. And 205s would look ******* ghey on a 12" rim.

So I don't understand are you going more towards performance or looks because your methods seem quite contradictory. You build power & get excessively wide wheels, then use tires that are made for stock size wheels/power. Dude seriously... if you care about traction, safety to yourself/car/others you should steer clear of that combo.

Actually, I want to see if those tires will even hold air @ the bead.

People do it all the time. But why would you bother with 15" rims? Thats just retarded. If its going to be a drift car, get some rims that are FD offset like 17x9 up front, 17x10 in back and stretch some 225s on there.

15 inch rims on a drift car... WTH is this world coming to...

Next thing I know, I'm gonna go to the track and see some caddy out there on 14" daytons sideways....

the only thing i can tell u is 16x12 with +10 offset u still have little clearance for the back with coilovers

15x12 will stuck outside of the stock fenders no matter how hard u can pull them thats a FACT

good luck with whatever else u are trying to do
