those rims in the op are the std rims we get, they are 15x5" front and 15x6.5" rear and come with 175 front and 195 rear tyres, i have the rears on 195's all round and they are fantastic
i got mine from the mercedes dealer i got the car from took 3 weeks and were very reasonably priced considering they are an O.E rim, or basically about 1/4 the price of a stock O.E toyota rim in the same size...
cos me approx $220usd each and they are made by ronal, the same people who make the brabus rims for the smart, they are made in poland!
