Did you know that some tires can vary in dimensions slightly, even if they have the same nominal size? 99.9% of the time, the differences won't cause any problems (assuming you're buying a set of four tires), but it is good to know that these differences exist in some rare situations.
Take, for example, the following three tires in the size 285/75R16:
All three pictured below are the same size and in the order presented above:
The size differences you see are differences in section width and tread width. Remember, those tires pictured are all 285/75R16 tires! Here's the breakdown of specs so you can see some numbers to help better understand:
- Dick Cepek Fun Country - section width: 11.7" and tread width: 9.3"
- BFGoodrich All Terrain T/A KO2: section width: 11.2" and tread width: 9.0"
- Goodyear Wrangler DuraTrac: section width: 11.3" and tread width: 9.1"
While these may not seem like very large differences on paper, the appearance definitely shows the difference. If you're looking to beef up the appearance of your truck and 285/75R16 is the biggest size that will fit, then you can go with that Dick Cepek Fun Country to get an even beefier looking tire than the average 285/75R16 tire!
