B2BFAB's guide for calculating and comparing your own tire sizes
The Golden Rule to remember - The wider you go in tire size or the lower the offset of your wheels, the smaller your overall tire diameter has to be to maintain the same clearance.
Tool #1 -> Tire Size Calculator
Normally, we suggest entering your OEM tire size then comparing different upgraded sizes to find what fits your goals, needs, look, etc. This handy tool gives you a visual interpretation of how width and aspect ratio both affect overall diameter.
Tool #2 -> Tire Rack
Enter your desired size, and check to see what's available. Always remember, just because you've found the perfect tire size, that doesn't mean there will be many or any All-Terrain options available.
Using the filter on the left hand side narrow down options. Normally, we are looking for On Road All-Terrain or Off Road All-Terrain options, but some sizes might have even more aggressive tire categories that you might want to explore.
Hopefully, this guide has been helpful in navigating the complex but rewarding process of finding the perfect fitment for your B2BFAB equipped vehicle.
Please also reference our B2BFAB Builds section to see the upgrades that we have paired with these sizes to get the look and performance dialed in on our builds.
