I've just recently swapped Summer Tires/Rims for my Winter set on my own for the first time. As it should be an easy concept, I went to a "U-Wrench" type shop where you rent a stall with a lift/tools for fairly cheap. I swapped the tires quite easily, using a torque wrench to tighten my lugs after to the swap.
My wheels seem to be tight, and I can't seem to find any loose lugs, but now my steering-wheel wobbles randomly left to right (fast). This happens on new roads and older ones. Could I just be paranoid as I've done this for the first time on my own? Or could it be that my Summer tires are wider than my Winters and I'm just not used to them as of yet? (8.5" on my Summers compared to 7.5" on my Winters).
Any ideas on what this could be would be great. Or if someone could just re-assure that I'm being paranoid, that'd help also!
NOTE: My vehicle is a 2011 Mitsubishi RVR (Outlander Sport in the States) if that helps at all.
