    Some suspension tweaks
    Plug kit, portable compressor.
    And I'm weighing the option of leaving the spare at home. I could shed a few pounds that way.

    I have coach builder +3" and a full size 275/65r20 (34.1") spare with no issues. However I did hve to grind and cold chisel the rivets out of the brackets for the factory spare to allow this.

    You can't run different tire heights on the same axle without quickly damaging the differential.

    For 2wd's the front and back heights don't have to match and the left and right front tire heights don't have to match, but the rear tire heights have to be the same.

    For 4wd's all four tires must have the same height or you'll destroy the differentials within a few miles. Different levels of tread wear won't cause you any problems so long as you don't leave it that way for 100's of miles.

    AWD cars (subarus, audis, etc) are even more temperamental. If you ruin one tire you have to change all of them. Even the same size tire with different tread wear will ruin the center differential quickly.

    In the interest of not over-thinking it; Your truck came with a spare. Use it if you need it. An inch or two shorter tire won't hurt anything for the short time it takes you to get home or to a tire shop.

    You do realize that the 2007+ Tundras are open differentials right. Not true limited slip. That is taken care of with braking.
    You can run different size tires no problem to get home. Def don't over do it.
    You can always turn off traction control if your worried.

    Yep, 2nd and 3rd Gen Tundras have open differential carriers (much to my disappointment). That makes it less of a problem than if it were an LSD or locker, but don't kid yourself. Heat and stress are what destroy mechanical assemblies and mismatch tires will produce both.

    It's still a problem for open differentials because they are designed to allow wheel speed discrepancies occasionally for turns, but not continuously. During normal operation the only significant friction (heat) in a differential is between the pinion gear teeth and ring gear teeth and in the carrier bearings and pinion bearing. Because of the gear oil even that friction (heat) is pretty minimal with the gear teeth accounting for most of it. The spider gears in the center don't move at all unless you're turning.

    Since the friction (heat) is low most stock differentials don't have any special provision for getting rid of the heat. Add continuous spider gear movement from different tire heights and you get additional friction (heat) where the spider gears touch the carrier housing, the spider gear pin and where the each spider gears' teeth mesh with each other.

    Since the differential can't get rid of the extra heat the temperature inside increases until the gear oil starts to break down and then the friction and temperature increase rapidly as the oil stops lubricating parts. Next, things start breaking (usually the spider gears or the spider gear pin) and your day comes to a grinding halt. (Besides a degree in Automotive Engineering and growing up in my dad's mechanic shop ask me how I know that this is what happens :annoyed:)

    If you don't believe me check out this article: http://www.deseretnews.com/article/822940/Different-size-wheels-can-ruin-differential.html?pg=all

    Excuse the ignorance, but how would it be any different then most cars or SUV's now that have a donut spare?

    It's not. Donut spares have a warning. Most say to drive them less than 50 miles and under 45 mph. It's not because the tire itself is unsafe beyond 50 miles.

    Here's a temp solution, until you buy a good spare tire bed rack. Cut the tabs off that locate the spare tire, Trim off that 4 ft section of pipe that comes after the muffler box. Weld in locating fingers on the underside to accept the 35's and be done. Or, throw the spare in the bed.

    Having a tire smaller on one side than the other means that the smaller tire is turning faster than the larger tire which means your axles are spinning at two different speeds. End result, one side of your differential is now trying to fight the other side to go in a straight line because they are not turning at the same rate of speed. Which means bye bye diff. That's why you see guys toss the stock spare as soon as they go 2 inches or larger of the stock size tire.

    Use the same tire/wheel combo for your spare just deflated. Have on board air and you're good to go.

    Sure. I need to do the same. My plan is to wait till i need new tires and keep the best one of the bunch as the spare.
