I may have a small air leak on my rear inside tire ( will know for sure tomorrow:)). If I find I do, is there any special things I need to point out to a tire service tech about changing the tire on a Foretravel? How to jack it up?
Also - if I can't get the pressure to hold long enough for me to get to a service center, is it ok to drive with one tire flat a few miles?
No! Do not drive for any distance with one flat dually at anytime. Call your emergency Road service people to help you.
if you drive any distance at all, you risk sidewall damage which will ruin the tire, if you can't get it to hold air, have them come to you for a mobile service call.
They will need to place a jack under the axle to raise the wheels off the ground
One point that seems to never be mentioned when talking about a flat tire on a dual wheel arrangement is the stress put on the axle bearings, mainly the small bearing, its main purpose is to hold the assembly on the big bearing, the big bearing is what takes the weight etc, the design has the center of the wheel assembly centered on the large bearing, take a look some day. The is why it is so much larger. When one tire goes flat, naturally the center of the weight is now causing stress on the small bearing. Point is, drive it easy and slow a shorter distance as possible. Seems only gear heads are aware of this issue.
