First off. I have a set of tpms sensors. I had them installed in my summer rims and just dealt with the light. So with my new tire install I had them pulled and are now for sale. sensor on amazon http://www.amazon.com/gp/product/B0...&pf_rd_t=101&pf_rd_p=470938631&pf_rd_i=507846 $60 for the set of 4 I also have 1 used Hakka rsi in a 225/45/17. Tire is still in great shape, I just potholed one and couldn't get a replacement, so I have been selling off the rest. This will make a great spare or replacement. Freeeeee, just pick up Russ
You have to reprogram every time you swap. The stock system can only hold 4 sensors. That is why I am no longer using these as a second set. Russ
The install will need to remove/reinstall the tire since they go inside the rim. As for the reprogram, you would need to hit up Tonka to see what they charge for that. I think it was around $40 when I checked last time (2 summers ago). Russ
