It's probably too early to tell what type of mileage hit you're going to take. I'm thinking it's going to be about 2 MPG.
I've read a lot of reviews on the Recon Grapplers and it seems they are a fairly loud tire. Louder than the Ridge Grapplers, which seems bass ackwards.
Those tires look great on your truck. I was looking at those too, but I just didn't want a heavy, E rated tire.
It wouldn’t surprise me. I’m going to get my speedo recalibrated Tuesday at the dealer. Speedo is off about 2-3 mph depending on the speed. Tested it with a GPS app with the phone 100% disconnected from the truck for accuracy. I have a 33” recal on it already, but since these are 34.6”ish, it’s thrown off again, but closer than it would have been on stock tires.
It’s odd, you’d think the Recons would be the quieter tire than the Ridges, I haven’t ever tried the Ridges. This was the first A/T tire I’ve ever had. They weren’t bad, my wife noticed a difference and mentioned It one time, but that’s about it. It wasn’t obtrusive, turn up the music a tad and it’s not noticeable, but noticeable vs. a highway tire. I just couldn’t believe these Baja’s were quieter, I would have expected about the same as the Recons.
