What I'm thinking now is that I'll just get a tire of the same (or very close) size to the 30's I have on it now. I know, they are "all terrain" and LRR is not a priority, but I feel too cheap to buy a nice shiny set of tires. Now, at least.
On a side note, my spare tire looks ridiculous compared to the "normal" big tires.
The offset is WAY in compared to the fancy-pants alloy rims (that were on it when I got the truck). That makes me think... if I got some skinny tires with rims that have less out-offset, I could make some wheel well skirts... hmmmm.
PS: close observers will note that the tire in question was the front tire. I rotated the back tire to the front and put the spare on the back. I had plenty of time, so I decided to mess with the front end as little as possible. Even though its alignment has only one adjustment, and a solid axle.
