0hcanada yeah, I know it's a wheel & tire discussion, but would also love to know the year of Grand Cherokee and the make & model of the roof racks/carrier.

Currently at close to 75k miles on my original Goodyears that I have kept in a 5 tire rotation.

Oh, and it's a 2015 black Altitude 2WD

Alright, pulled the trigger on the 9" 265 combo

I went with 5 20x9 TrackHawk replicas with 265/50 Pirelli Scorpion Verde All Season Plus IIs

Ordered from Discount Tire Direct so I'll post before/after pics once they arrive and I get them installed.

I’m currently running 20x9 trackhawk replicas from eBay and 285/50 pirelli and love the look and fit. I dropped the suspension slightly as well to reduce some wheel gap on my trailhawk. I can’t say I have any experience with the Michelin but I do like the PIrelli ride.

Also taking your advice and ordering Michelin Defenders which fit my driving habits and the sale price is right.
Yeah, my 2002 Town and Country Limited had them before it was mandated. They lasted over 10 years, one was still working after 13 years, 130K miles. What my personal recommendation would be is, if 1 fails, replace it, if 2nd one fails, replace it, and plan on ordering 2 more for the rest at your convenience within 6-12 months.

ColdCase The WK2 sensors transmit pressure and ID about once every minute at speeds over 15 mph only. They don't transmit otherwise unless forced by a tester.

JackB1 Just thought I would post the following info regarding TPMS life;
The estimated life expectancy of an OE TPMS sensor is 5 to 12 years, with the average lifespan being 7 years. TPMS life expectancy is directly related to the number of radio frequency transmissions the sensors make. Driving habits greatly influence the number of RF transmissions a sensor makes in its lifetime. For example: sensors usually transmit when the vehicle is stopped and transmit more often when in motion. Maintaining a constant speed, such as when you're on a highway, reduces the demand on TPMS sensors and allow the sensors to transmit less often. Drivers who often find themselves driving in start-and-stop type traffic will have a greater impact on the vehicles tire pressure monitoring sensors. Weather can also have an impact on tire pressure sensor battery life. Cold conditions allow batteries to last longer. Warmer conditions take more of a toll on TPMS battery life. These remind me of the EZ Pass senders in our cars which have about a 10 year life, something I learned the hard way.

Lastsummer Really great info here gents.
For my S4, I can tell you all of the offsets, tires sizes and wheels that will work and how flush to the fender they will come.
Whole new ball game with fitments here.
I think I might take the gamble and give it a go.
If anything it forces me to do the leveling kit and start the modding process. WIN WIN I guess...

Longer metal ones have a tendency to break off where rubber is more flexible. Metal valves can be shorter, however, more stylish, less likely to leak. Metal valves seem to last longer, but then its the battery that limits life anyway. Rubber ones are cheaper to make/sell and thats what the OEMs are.

Make sure you get the correct frequency for your year when looking, which is what ColdCase is referencing, I believe.

Any feedback?
The lug pattern is the same, so technically, they will fit. The backspacing is a little less, so the will push out toward the fender more. If you have the HD brakes, they will NOT fit w/o spacers. Rear vented brakes is the easiest way to tell, if you aren’t sure.

Most people upsize they’re tires, anyway. I’m running 265/65r18 Ridge Grapplers and my speedo is off ~2mph @ 70. Alfa OBD or others can correct tire size changes.

I think the sensors should work, but 2017 was a transition year so they may not. If you have SD brakes, there should be no issue. There are large production variances and not much clearance, so one set of Rubicons work, while another one interferes and needs spacers. I think the so called Sahara wheels fit more reliably, but the fitment report thread is full of JK wheels needing spacers to clear the calipers. One never knows until you try them, But they Do fit better with worn brake pads. Fresh pads may be an issue.

There are sensors in the MOPAR supply chain and there are those that bypass them. Early models were made by lucas in the UK, and you would often find a set of 4 for like $40 on ebay, now they are less. I put a set in my winter tires 9 years ago and they are still working. I rarely hear of any issue on these so called cheap sensors. They are the OEM sensors without the MOPAR overhead, like those roof cross bars out of china.
