Stock style wheels question

[memphisrain]

I was wondering if there were any wheels (factory or aftermarket) that would allow me to use the stock center caps, but are wider to accommodate bigger tires?

I was really digging the look of this truck:



but would like to run some bigger meats. Will that center cover work on a rally wheel from a new truck or am I looking at having to have the wheel widened?

Thanks,
