On a very rainy day last Fall we were traveling on the interstate in NC and decided to stop at a rest area for lunch. After lunch I exited the coach for the normal walk-around inspection before proceeding. Much to my surprise I discovered a flat tire in the left front of our Honda Pilot towed. I installed the Honda's compact spare tire and considered my options which were few. Obviously I needed a full size tire because of the speed/distance restrictions of the compact spare. I thought about leaving the towed at the rest area and searching for a tire in the coach, however I decided to proceed with the coach and towed to an exit twenty miles south where there was supposed to be several tire shops. It was very hard to limit the coach speed to 50 MPH which was the speed limit printed on the compact tire, and I felt very "at risk" of being rear-ended.
Long story short, about two hours later we had a new tire and we were back on the road. Needless to say I now have a full size spare tire which I hope I'll never need. I'm posting this as a heads-up to other who might be towing a vehicle with a compact spare, please do yourself a favor and get a full size spare before you need it.
Warning for those who tow vehicles with AWD, you'll need a full size spare that matches your other tires exactly. Tire diameter is critical and if it is incorrect the vehicle will interpret the difference as wheel slippage and engage AWD.
OHH! Never thought of that! Thanks for the head's up.
