Now I have found several sizes near to what I need but not spot on. I found some good part worn 225 60 14's......will these be okay or will I skid off the road as soon as it rains?? Personally I thought it'd prob be fine but

Also if the above is okay could I even fit 185's to the front (and wider at the rear)or are they too narrow for the rim (Magnums) ?
I know its not the best me for going for part worns but I'm not sure if I'm keeping these wheels and I'll never get through the tread on a new set with the small amount of miles I do so it's just a stop-gap so to speak

Advise much appreciated!!!!!!!
