Spare tire
« on: January 08, 2013, 07:07:49 PM »
I've been lugging a spare tire in my bus' basement for thousands of miles.  I suppose it's just taking up space and burning fuel -- that is, unless I have a flat.  I figure if I have a flat I'm not going to change it myself anyway. 

Question, is anyone else lugging a spare around?

For us it depends on the size. We had a cracked rim in boondocks Alberta (just a few hours from the NW territories border). Even with the logging trucks up there, they didn't have that size rim. We slapped the spare on and were on our way. Ours is fully ready to go, even though I doubt I would swap it out myself.

Bus didn't have one when we got it, couple of years later we got an unmounted tire, a year or two later i got a new wheel for it and got it mounted. Have the tools and the ability to change it myself. Don't want to have to rely on other people if at all possible.

Had our only blowout last year heading down to busconversions bus rally.  Tow truck driver from Good Sam had all the right equipment but no easy access to 12r22.5 tires.  So even though it was (at that time) on the wrong rim, the fact that we had the right tire saved us a lot of $$$ and wasted time trying to find the right tire for the bus on a weekend.  He swapped the tire on the spot & got us going in under an hour.  I was very glad we had the spare with us!  PS - we now have 6 new tires and the correct rim.   :D

Yes, I carry a spare.  It's a horrible "get off the road quick and change it later" spare but I don't have any faith in a mobile truck having access to a 12R-22.5 when I happen to need  one.  It's not as common a tire as say an 11R-22.5 would be.

As a newbie, we don't have any bad experience with tires yet.  We don't carry a spare, the front tire compartment on our MC-7 has an AC unit in it.  After reading this thread, I'm seriously considering carrying one.  We have a spare tire and rim, just need to get it mounted. Man, that's going to take up some space! New tires are in the plan but not for a couple of years.

No spare. But I carry all the tools to take a dually off and use it where needed. And I know the nuts will come off because I take the wheels off every winter for maintenance. We have Coach Net also.

My bus came with a spare wheel, jack and wrench - it's obviously intended that you can change it yourself, so it would never occur to me to 'phone someone else to do it for me. I've changed wheels on the bus in order to put new tyres on, but I've never had a flat so don't know if the extra jacking required then would make the job much harder - but I don't really see why it should.

A shameless plug for my business - visit for back issue magazines - thousands of titles covering cars, motorbikes, aircraft, railways, boats, modelling etc. You'll find lots of interest, although not much covering American buses sadly.

No extra jacking needed if you carry run-up block(s). If the flat is on the front, run the tire onto the block and jack normally. If it is the outside dual, run the inside tire onto the block and no jacking required. Inside dual, just jack normally. With the run-up block(s) you don't have to worry about clearance below the axle for the jack.

I carry a spare after getting raped on a used tire, when I had a blowout, when we first got the bus. I also have the tools to change a tire if the need arrises again. I will be getting different steer tires this spring, so all the tires will be within the recommended less than 7 years old.

Good luck, Sam

We do not carry a spare.  I have extra rims, so I would just need a used tire.  If we were to have a flat, a spare would obviously be more convenient than using one of the duals to limp along.  Our tires, however, are 11r 22.5 so we should not have trouble finding one most places.

Yep. We carry one. If you never remove it, you'll never even know how much space you're missing  ;)
