Most of you probably know this already but my DC Limited came with 20" wheels and the spare is 18". In addition to having a crappy steel rim without the TPMS sensors it is also a smaller and cheaper tire. This is disappointing considering how much I paid for the truck, especially paying extra for the wheel upgrade, and I suspect it may be unsafe for the following reasons:
Now I realize that spare tires are just supposed to get you to the nearest repair location but in some states that could be 50 miles or further. With my luck I would get a flat in the rain or snow, while towing or hauling a heavy load, or while using 4x4 mode to do some off-road driving. So it seems entirely inappropriate to me for Toyota to save roughly $20 per vehicle and stick us with this junk. I would have been glad to spend a little extra to make the spare tire match. It's not like this is a 4-cylinder Corolla where you can limp around on a donut, this is the TUNDRA we are talking about! King of the 1/2 ton trucks but with a wimpy and lame spare tire. Guess I need to add a new tire to my list of future upgrades... grrr...
- The manual says to always use the same make and model tires on all 4 wheels and to replace them at the same time.
- The truck could be in 4x4 mode which would lock the wheels and make the smaller wheel spin faster.
- The truck may not handle a load or trailer safely with the smaller tire installed.
- The different tread pattern and size might make the truck pull to one side.
