C load range spare


just noticed my spare tire is a "C" load range with a max weight of 2150 while both tires on my 19 footer are "D" range with a max weight of 2450. my question is this, should i have to use the spare while traveling will i be able to "mix and match?" my trailer is about 4500 lbs wet. i could empty the fresh water if i needed to. all other weight is carried in the back of my truck.

does the board think i would be okay using a "c" and a "d" rate at the same time?

The C-range tire will be close to maxing out with your weight, even considering the tongue weight but also considering the possibility of uneven side-to-side loading. If it were me, I'd keep the C as a spare-only...using it like you do the small doughnut spare in an, when needed to be installed as a spare, drive at slow speeds and short distances directly to the next flat-repair place.

Then, when I need to replace my tires, I'd buy three Ds.

Load range C & D tires have the same dimensions, so your trailer should run o.k. with the spare. The C tire is overloaded so travel slowly to the next tire store. If your surviving D tire is three or more years old, I would consider replacing it as well and using your surviving D tire as a spare. In hot weather, the risk of blowout on the overloaded tire is increased.
I have had three blowouts in one year with D rated tires on my 25 foot Safari. Trailer tires of any make don't seem to be very well made and are prone to blowouts in hot weather.

I wouldn't even use the C rated tire as a spare.

My 25FB (tandem axle) came with D's. We had three blowouts out west last summer. We replaced all our tires with Maxxis E's.

Depending on where you are and what day you need to use the spare, limping along at slow speed may not be a great option. Here in the Southwest the next tire shop could be several hundred miles away and the chances of finding an open tire shop on a Sunday or holiday weekend are pretty slim. Having a spare that will let you continue your travel at a normal pace with no worries about load rating or handling characteristics would be worth the price of a new spare to me.

Odd - my '97 25' Safari came with factory-spec'd C ranges - and says so on the tag. I'm surprised that David's 19 footer is maxing his tire.
