hey. i am lookin' at ditchin' my VH SLE rims in favour of fatter treads, but was wondering what sort of tyres will fit onto stock steelies with hub caps?

i was hoping for something around 245's for the rear, but am willing to be realistic.

there is a set on ebay which are 7" but will that go up to 245?

can you get steelies that will fit something that large?
