Biggest Radial Tire On The Biggest Beadlock Available

This magazine was literally shipping to the printing press and the rubber was still curing when we got our hands on the first 41.5-inch radial Rocker tires from Pit Bull and mounted them on the biggest beadlock wheels available from Trailready. The package is so new, in fact, that we didn’t even have two hours go test ’em, so be sure to look for a lot more on the newest offerings from Pit Bull and Trailready, as we’re sticking this set on our project Blazer that is busy getting revamped at SMP Fabworks right now.

The Rocker is now the biggest light-truck radial tire offered (when measured from the ground to the top of the tire’s tread). Though it’s not a new design, the 41.5-inch size is brand new, and should be available to purchase by the time you read this. We mounted them on TrailReady’s new 20-inch HD beadlock wheels because it’s the most heavy-duty and biggest beadlock-ringed wheel available. The HD Series isn’t some production wheel with a cut-off bead lip; it’s a cast-aluminum wheel with no welds that was meant to be a beadlock wheel from day one.

Why run a 20-inch wheel? It is true that we typically preach to run the smallest wheel you can for the brake package your vehicle has. Sometimes, a tire is so big that you can have too much sidewall flex for certain driving conditions, and increasing the wheel size can actually improve the handling of your vehicle. Generally, bigger wheels are acceptable as long as they’re half the diameter of the tire, making these 41.5-inch Rockers mounted on 20-inch HD beadlocks a perfect package!
