Yes, you will have TMPS error if your do not have the sensors in your rims. No other problem related other than the display. I am running my friends wheels '06 on my '07 for the whole summer and had no problem other than the annoying light.
You might check on eBay or Amazon for TMPS sensors... at a price you can afford to buy four... and hopefully the guys here can give input as to what might work.
I was a little premature :squint: (in this case only) and went off and bought 4 on eBay for $20 each.
I plan on getting wheels for Christmas (Santa has my list) but won't put the tires on until spring... but I went ahead and pulled the trigger. Should have asked the Forum first, since I won't test them out for 5 or 6 months... but it wasn't a huge risk, and the reviews on the guy were good... so hope these work.
Here are pics and PN of the sensors which were said to be OEM...? Also see other mfgs on Amazon... If you can add for under $100, worth the effort.
