I put on 35" Nittos and am getting low- to mid-17s on local street driving, but luckily still in the 19+MPG range on freeways. As others have written, invest in some type of app or module to check your settings - I recently did the Tazer Mini and finally got everything calibrated correctly. It's...
$100 - tires only, with ~8,600 miles on them. Had them on Craigslist for quite a while, and honestly I was just happy to get rid of them. They weren't in terrible shape but they definitely showed signs of being out in the desert.
Yup - same here as the OP. Some sluggishness when I went Nitto Ridge Grappler 285/75/18s on the OEM Overland wheel, and some hunting between 7th and 8th gears. Have since calibrated with my Tazer Mini (took a few tries to find the right tire-to-speed ratio/size) and the MPG and shifting is doing...
Just got the Tazer Mini calibrated this week - I received it a while back, but have been playing with it since in order to get the settings right. So far, the hit appears to be 2-3 MPG on local streets (was in low-20s before, am now in the low-17s) - reminder, Phoenix is VERY flat. Not very much...
Update - now that I've put it on and off SEVERAL times, it is definitely fitting much better, AND is easier to install/take off. In short, much better fit now that it's broken in and shaped to the cab.
Like many things in life, there's just a bit of room for improvement - I've only put it on a few times, so maybe it needs a little breaking in. The top fitment could be a bit more taut (in case of rain) and the windshield portion isn't completely flush - maybe with time it'll relax a bit...
Put on the Mopar cab cover - weather this week in AZ is perfect for having the top off, so the Overland is getting tucked in with its new cover nightly.
Just bought 4 Nitto Ridge Grapplers (285/75/18) at $322 apiece, so yes - I absolutely bought the certificates. I've been in too many situations where tire shops (plural, not one in particular) basically say a tire is not fixable, so a new replacement tire has to be purchased. This happened once...
I would have held down the horn and scared the F*ck out of him as best I could. I had a similar situation a few weeks back - no kicking of tires, but an older guy (older than me, at least) walking around my Overland admiring it - said he hadn't seen one in person, but had read a bit about them...
Mine wanders, as various others have noted, and I have to give continual input to the steering wheel to stay between the lines. I've unfortunately grown used to it, but will definitely contact the dealership to get the TSB process rolling. I say I've gotten used to it because I occasionally...
I am not an engineer, nor do I hunt, but I am definitely going to monitor this thread for results - and for the OP, we NEEED PICs should your hunt prove meatful (not fruitful). :rock:
