I have a 1990 F150 and I was wondering if I would be able to fit 33x12.50x15 tires on the stock wheels. I believe they are 15x7 but I have not actually measured them. I realise there is a greater chance of increased tread wear and I might have to run them at a lower psi. The reason I ask this is because I can afford new tires, but not with new wheels just yet. I'm 17, in high school and working at a gas station to make money. I've scrounged up enough for a 3" lift but the stock 235's look pretty stupid at that height. If the tires will fit I can make due till I get enough for some new wheels, I just need to know if they will fit. Thanks
