Honestly, 17'' rims and tires will work out to about the same as just 19'' tires. Plus, if you use your stock rims, you are going to have to pay to have your tires re-mounted and re-balanced twice a year for the life of your car. Thats $24 - $30 per wheel! As for the TPMS... They are not necessary to have on your dodge Journey. Save yourself the $300 and buy a tire pressure guage. Or better yet, have nitrogen fill put in your tires. Major benefits to that. Just my thoughts.
