The CDF and \D0 collaborations have used recent data taken at the Tevatron to perform QCD tests with $$W$$ and $$Z$$ bosons decaying leptonically. \D0 measures the production cross section times branching ratio for $$W$$ and $$Z$$ bosons. This also gives an indirect measurement of the total width of the $$W$$ boson: $$\gw=2.126\pm0.092 GeV$$. CDF reports on a direct measurement of $$\gw=2.19\pm0.19 GeV$$, in good agreement with the indirect determination and Standard Model predictions. \D0's measurement of the differential $$d\sigma/dp_T$$ distribution for $$W$$ and $$Z$$ bosons decaying to electrons agrees with the combined QCD perturbative and resummation calculations. In addition, the $$d\sigma/dp_T$$ distribution for the $$Z$$ boson discriminates between different vector boson production models. Studies of $W+ Jet$ production at CDF find the NLO QCD prediction for the production rate of $$W+\ge1 Jet$$ events to be in good agreement with the data.
