hmm. that is tough.
It wouldn't look horrible on the 33s. esp if they are an aggressive tire. There was a guy on here who had a 6in on 33s that were just street tires and it looked kindy goofy. But wasn't as bad as I thought itd be.
I would save the headache and just go for the 6.5. Maybe you can find someone to sell the good condition 33s to and buy some 35s. It wont look awful.
