Odd Question

Hey guys, I recently bought a 2010 base Toyota Tacoma 4x4. The truck came with 245/75/R16s. I recently bought new wheels and 265/70/R16s. While looking at both sides of the truck, I noticed there was more space between the rear tire and the top of the fender on the driver side opposed to the rear passenger side. Driver side is about 10 inches in between and about 9 inches in between the passenger. The suspension is completely stock. I looked around and can't find a solid answer. Has anyone had this problem before?

 

Didn't one of our female members have this problem too? Right rear fender sat lower than the left rear. And didn't she figure out that the bed was off-kilter for some reason? Might take a lot of reading and searching to find the answer. Seems like it was within the last 6 months.
