You'll be happier if you bite the bullet and go ahead and replace the rubber stems with Steel stems.
You can buy them long enough to extend through the wheel covers and still have room for tire pressure sensors. I bought mine here: DL1SP13 Chrome Duallyvalve Kit
. Ask for Mike. He's sold a lot of these for Soleras and knows what you'll need. (I have no connection or interest in this company)
A set for the rear duals is $120. I bought a set for the front tires also. Total cost was less than $150. I paid my tire guy $8/ tire for installation and balancing. Took 4000 mile trip last month after installation... no problems, no pressure loss, pressure sensors functioned beautifully.
The metal stems will allow you to safely inflate the tires to a higher pressure for better fuel mileage, too.
