Mounting slicks on rims

[turboost]

When do you need to put screws and/or a tube in. I plan on running some 28x10.5 on some 15x8 rims. I do plan getting a 3000 stall converter and a bigger turbo for some 10lb launches.

BTW what kind of backspacing should I have on these rims?
any other suggestions are welcomed

3.5 backspace would be good

you can try no tubes.....just check and see if the tires rotate on the rim...if not, you are good to go....just keep 'em aired up

if you use tubes, by all means use screws

if you run 1.5x 60's....tubes & screws
