sparetires ain't for real men ... i run my rig also without sparetire ... sorry - couldn't stand to post a pic of a non hamb-approved vehicle here
on my O/t cars I used to build I carried a spare that was a little bigger than the front tires I used ( 6" wide vs the 4" wide ) and if needed could go on the rear to get the car on a flatbed or trailer or driven slowly home as the rear 14" were backset real deep and made it wobbly , and luckly never had to use it ever .
