The thicker the sidewall of a tire, the more suited it is for wheeling. Deflating a 27 to 32 inch tire slightly will increase your Wrangler's footprint, giving a larger grip area to assist climbing rocks. The larger the tire, the larger surface area you can create. Don't get left behind on the trails! Ensure your Jeep's capability and upgrade your tires to accommodate your hobby! Not only do Wrangler 27 - 32 inch tires increase the functionality of your Wrangler, but they also add an aggressive, off-road look to your rig.
