Change options layout

I am lost.

I need to adjust the space between the product option field description and the option radio button/description.

See here for example:


The space between “Tire system”, “Wheel system” and the corresponding radio buttons is too wide causing unsightly text wrapping or even causing it to be partially obscured.

I tried to identify the CSS that dictates this spacing, but there is nothing that I can see. I also looked at “customer/views/products/components/product_options.tpl”, but there does not seem to be any formatting done in there.

Please help.
