Ok, everyone running oversize tires; what do you do about your spare tire?
Are you running a matching spare, or a factory spare? If your running a matching spare, dose it fit under the bed? I ask this question because i notice a common tire upgrade to be a 33 or 35 (or equivalent), but I have not seen or heard of any mention about a spare. If your running a 33, and have to use your factory spare, wouldnt that be he11 on your axles? I realize a spare is just that, just to get you home, or to the shop (point A to B). However sometimes that can be quite the drive! It's been to known to me (and it makes sence) that if you have one size tire on one side, and a different size on the other, the axle will be trying to turn at 2 different ratio's. Again, Im just currious, cuz Im lookin at a tire upgrade come spring time, and I dont know about this issue, or if there is one!
Thanks

 

If you have a flat, you'll just have to make sure the spare is in the front. If you have a 4x4 you better not have the front axle engaged, or your right, you'll be looking for a rear end shop.

 

good question but how about use some kind of fixed flat rattle can? no need to change..

Or buy some plug w/ stick sticky and air compressor.

IF nothing above..try air down all 3 tires down to 25psi it might almost same height as spare tire like 275/65/18 then drive slow to local for fix a tire (plug in stick sticky, air it up and go!)

YOMAN!

 

I've had to help people with badly mismatched spares lots of times.
If you have an open rear you can drive a LOT of miles with mismatched sizes.
On the front, as has been stated, you will have no real problem, besides the funky handling and the truck leaning over...

Even with a limited slip you can certainly drive 20-50 miles at low speed with mismatched tires.
You might get some ratcheting, or you might not.

I live in one of the biggest off road areas and you are always seeing someone break a rim, tear up a tire, etc. and have to limp them back into the city.

I never saw anyone blow a rear end, much less a front end, from even badly mismatched tires.
Of course I never saw anyone going 75 mph that way...

The only real danger is that you will put it on and just leave it there. Now that will eventually bite you.

 

While I sold the fix-a-flat and its thousands of clones for years, I really, really, wouldn't recommend using it on our trucks unless it was life or death.

It can destroy the balance on tire and these trucks are Very sensitive to balance.

Lots of places won't even try to fix a flat after you use that stuff. It may be different in your location but in Southern California it is rare to find anyone that will attempt to fix a 'glopped' tire.

Lowering the tire pressure does almost zero to changing the rolling diameter of the tire. You merely create the illusion that the tire is smaller. It is still the same distance around when you rotate it. And it's not the sitting height but the rolling diameter that matters.

Carrying a tire plug kit and an air supply like Yoman suggested is the best cure.
If you do serious off roading an air compressor is very handy for re-airing your tires after good sand run anyway.

Have you ever been driving down a large higway and notice some moron in an old Caprice running like 90mph on a dinky little spare?

I see that just about every day, but I live somewhere near Philadelphia... High population of morons in Philly...

 

Yep, I have seen that, more times than I want to admit, but never on trucks.. well, almost never.

God must love idiots. He made a lot of em...

There's also the very nice side effect of the propellent used in some of these flat fixers being extremely flammable. Not fun for the guy that might have to fix your tire afterwards.

 

A 35/12.5/18 will fit under the bed of an f150 with a hidden hitch. I have it under their right now.

 

That's good to know...then a 35/13.5/18 should fit too, that's what I have.

Anyway, all I ever had is a lifted truck. Everytime I had a flat I just put the stock spare on and drive slow to the nearest shop. In SoCal thers a shop every other block or so, not a problem.

 

WOW learned something new!! Good thing i never used it.. thanks! YOMAN!

 

I want to add something about air compressor since i have 2 of them !

I HIGHLY recommend this one air compressor.. its CHEAP and only $50 bucks unless you can find much cheaper than $50.
Heres the link http://www.dv-innovations.com/products/mf_50.htm

Its the SAME air compressor with 2 different model number at some store MV-50 or MF 1050.

I know that Pep boy, Wal mart and few auto stores carry it..

Ebay- surprised me its $75ish.. http://cgi.ebay.com/ebaymotors/TSUNA...QQcmdZViewItem

Its much better than ARB air compressor and Vair (low model) air compressor.

Heres some cool to read. http://www.zookpower.ca/forums/showthread.php?t=2628

From 15psi to 30psi (after beach 4x4) all 4 tires it only took about 10-15 min!

I used it pretty often and has zero problem.. it has bag to carry it etc its cool!

YOMAN!

 

That all steel little compressor looks like a very handy one.

I used to sell a half dozen plug in compressors, all of which were about useless on a truck like ours. They were all plastic, and if they worked at all on a big tire, they burned up the wires to the lighter...

For my beach use I have one of the 100 buck A/C powered compressors, very small and light. It works great but must weigh twenty pounds.
I got it to carry in the motorhome and have been saved by it on occasion.
I have a genny in the mh, of course.
When I have carried it in the F150 I also carry a 900 watt converter that clips straight to the battery.
I've used it two or three times but only on other guys trucks... Like jumper cables or a tow strap, it's something to help others more than yourself.

hey thanks for all the info guys! Im going to pep boys later this afternoon, think i might just have to pick up one of those compressor YOMAN is talking about!
Its also good to know that a 35 tire will fit under the bed, thanks powerage.

 

who needs a spare when you have a cell phone??? I will call somebody to bring me one!!
