Same issue I am having i was getting like 22-24 mpg, now 17-19 mpg with 265'sss. I might get some re-mapping done to bring my mpg's back.

Re: Some thoughts on owning an 08 Jeep GC diesel...

Re: Some thoughts on owning an 08 Jeep GC diesel...

I think I'm putting factory rep 20's on here asap and running 255-265s on them. I wonder if they will make things worse.

I am running Blizzaks in 75 degree LA weather... so I think the sticky tires aren't helping my mileage much...

How do I do a remapping in the US? I know you euros have great diesel resources...

Re: Some thoughts on owning an 08 Jeep GC diesel...

I am sure you know this already but snow tires are not supposed to be used in higher then 45* weather because they are too soft for the heat and will wear out super fast.
