Wheel Lug Nut Torque

I know this sounds ridiculous, but everywhere I look I get a different answer re: lug nut torque for my 2015 High Altitude. Owners Manual gives different spec than service manual. Goodyear is different than Firestone. I see everything from 85ft lbs to 150. Does anyone really know what is correct???

100 ft lbs is a good baseline for 90% of all passenger vehicles. 150 is too much for most, except for heavy duty types.

Re: Wheel Lug Nut Torque

'14 FSM says 100+-15 ft-lb.. I don't imagine '15 is different, but I don't know.

Re: Wheel Lug Nut Torque

Page 201 of my '15 owners manual states 130 ft/lbs, except the SRT, for which they call out 100 ft/lbs...........

Re: Wheel Lug Nut Torque

I know what the manual says. Service manual states 100. Local tire shop says 85. Now you can see how confused I am.

Did the local tire shop build the vehicle?... there's your answer.

I personally choose 105 ft lbs on my SRT.

Re: Wheel Lug Nut Torque

The bulk of my past experience was with GM cars, and a couple of the compact GM pick-ups. Their torque spec, after they pretty much went "all-in" with aluminum wheels, was 100 ft/lbs. HOWEVER those vehicles all had 7/16" lug studs. I believe the Jeep GC has 1/2" studs, so I could understand the higher torque spec.

Re: Wheel Lug Nut Torque

I was just checking the service manual which states 100 15 which is what I'm used to seeing. 130 lbs that the owmers manual states sounds a little high on alloy wheels. Id stick with what the service manual says that owners manual is often riddled with errors, the 2014 is on its 8th edition. it had the 2014 5.7L spark plug change at 30k for the first few editions when its supposed to be a 100k I bet a lot of folks that are sitting on old editions are putting a lot of money into plug changes that don't need to. that 130lbs is probably a few decades old and just one of the many things that the editor that creates 8 editions of an owners manual in one year never bothered to check. and don't listen to a tire shop whatever they say they will often just use a general standard. Id stay at the service manual 100-115lbs, set them at 110 and be done. just my opinion
