We predict the presence of several magnetic Feshbach resonances in selected Zeeman sublevels of the isotopic pairs 40K\mathrm\text\ensuremath-87Rb and 41K\mathrm\text\ensuremath-87Rb at magnetic fields up to 103 G. Positions and widths are determined combining a new measurement of the 40K\mathrm\text\ensuremath-87Rb inelastic cross section with recent experimental results on both isotopes. The possibility of driving a K-Rb mixture from the weak to the strong interacting regime tuning the applied field should allow one to achieve the optimal conditions for boson-induced Cooper pairing in a multicomponent 40K\mathrm\text\ensuremath-87Rb atomic gas and for the production of ultracold polar molecules.
