Update on the all terrains, one of my biggest fears with swapping tires was ruining how well this thing drives, and I hadn’t been all that happy with the the change. I was expecting some road noise, the lower speed parking lot rumbling/vibration, a bit harsher ride over small bumps, and a little more pulling/wandering, but it has felt like one of the tires was slightly out of round from 40-70 mph. It wasn’t horrible but it was annoying enough that I couldn’t deal with it on a long highway trip, it would have slowly driven me nuts.
I let them heat cycle, tried a bunch of different tire pressures, and finally went back to Discount a Tire after reading about road force balancing. Of course they talk to you like your an idiot, “yeah it’s going to ride worse,we road force balance all of our tires”, etc. They had also underinflated the front tires to the 33 psi on the door sticker, argued that I didn’t need more than that, and acted like I was wanting to run them at the pressure listed on the sidewall until I told them that was 80 psi.
I found 40 psi F, 45 psi R to handle the best, I didn’t notice much difference in ride quality throughout the whole range I tested. I called BF Goodrich to try to get the numbers they recommend based on what their website says to do, and after a bunch of back and forth and them doing hand calculations, the lady says “we recommend staying below 50 psi.” When I told them I was hoping for specific front and rear pressures, she hung up and eventually called back saying these tires were not recommended for this vehicle. Ok, whatever. They are on half the F-150’s in this town and the LR3 weighs a little more than that. Call it an F-150 with 800 lbs in the bed, probably distributed the same.
I’ve run BFG AT’s, 2 sets of KM2’s, 2 sets of Super Swampers, 2 sets of Ground Hawgs, Toyo AT’s and MT’s, and Nitto and Cooper AT’s, from 32” to 40”. This set of KO2’s was definitely in the worse riding half of those tires, although I don’t know that it would have been noticeable on a vehicle that didn’t drive as well.
They eventually road force balanced them again, and found that one was at 44# and another over 30#, despite them claiming to have done it the first time. They spun those two on the wheel and claim they are all under 8# now. Overall, it’s a MUCH better ride and I’m happy with my choice now.
