if i replace the stock rims (20's) with some aftermarket ones how do you deal with the TPMS warning. also what happens if you go with different tires that have lower tire pressures than recommended?

 

Just take the old sensors out of your stock rims and put them in the new ones. Also I don't think they operate on a set pressure. They sense a percent change in pressure, so once they're set it doesn't matter what it's set at, just the change.

 

can you buy aftermarket ones if i want to keep the my stocks as winter or spare tires?

 

Yes you can. Just check around for pricing, because when I checked the prices varied greatly. From $30 ea. to like $90 ea. Check ebay for mopar take offs as well.

 

got a set on ebay for 20 bucks, they got lost in the frikken mail, no insurance
