Scion TC Bolt Pattern (2005 – 2016)

The Scion tC is a sporty compact car made by Toyota under its Scion brand. Legend has it that the tC stands for ‘Toyota Celica’. So, the Scion tC is supposedly the spiritual successor to that legendary vehicle. The tC was made in two generations spanning 2004 to 2010 and 2010 to 2016, respectively. Regardless of which generation you have, eventually, you are going to need to know the Scion TC bolt pattern.

If your Scion TC was made between 2005 and 2010, then it has a 5×3.94 inches (5×100mm) bolt pattern and a 2.12 inches (54.1 mm) center bore. If, on the other hand, your Scion TC was made between 2011 and 2016, then it has a 5×4.50 inches (5×114.3mm) bolt pattern and a 2.37 inches (60.1 mm) center bore. Both generations use 5 lug nuts that have a thread size of M12 x 1.25 and a tightening torque of 75 ft lbs. 

This is very useful, but it’s not everything that you need to know. There is a lot more info to learn in regards to the wheels and tires for the Scion Tc. 

In this article, we will outline the Scion Tc bolt pattern in extended detail. After that, we will go into what type of lug nuts need to be used for the TC. We will then cover things like the torque specifications of the bolts and the center bore. Finally, we will go over all the tire and rim options for each generation’s engine configurations.

Wheel Fitment Specifications Per Generation

If you are going to fit a wheel on your car, then you are going to need to know more than just the Scion TC bolt pattern. So, below we have taken the liberty to outline all the factors that you need to be aware of for each generation of this vehicle. This information includes the center bore diameter, the thread size of the bolts, and the lug nut tightening torque.

2005 – 2010

If your Scion Tc is equipped with a 160 HP 2.4L I4 engine it will use tire sizes of  215/45R17, 205/55R16, or 225/40R18 and a rim size of either 7Jx17 ET45, 6.5Jx16 ET45, or 7.5Jx18 ET42.

If your Scion Tc has the more powerful 200 HP 2.4L engine, then it uses a tire sizes of 225/40R18, 215/45R17, or 225/35R19 and rim sizes of 7.5Jx18 ET42, 7Jx17 ET45, or 8Jx19 ET38.

2011 – 2016

If you own a Scion Tc that has the 180 HP 2.5L engine, then it uses a tire size of 225/45R18 or 235/35R19 and rim size of 7.5Jx18 ET39 or 8Jx19 ET35. If, on the other hand, you’ve got a Scion Tc with the 179HP 2.5L engine, it’s going to use tire sizes of 225/45R18 or 235/35R19 and a rim sizes of either 7.5Jx18 ET39 or 8Jx19 ET35.

Properly Tightening The Bolts

All Scion TC sedans use 5 lug nuts that must be tightened in a specific criss-cross pattern and to a specific torque level. This information is readily available in the Scion TC user manual, but we put it here for you with the rest of the info.

First, tighten your Scion TC lug nuts with a basic hand wrench first. Make sure to not tighten them all the way, because if you do, you’re not going to be able to get them all tightened properly. Also, tightening them down in the wrong order could be dangerous as it could cause serious vibration and alignment issues.

After that, tighten them down with a torque wrench to the appropriate ft lbs. Make sure to do this in a criss cross pattern. The Scion TC lug torque is 75 ft lbs. Again, if you simply radially titan your lug nuts, you could run into serious issues later. 

Also, don’t just trust it! Make sure to perform a lug nut loosening test. This can be done by driving for around 30 miles and then checking the torque on all of your lug nuts. If any of them come loose, tighten them back down again and drive for another 30 miles or so. If any of your lug nuts are loose after the second test, then I have bad news for you. 

That means that your rim is warped and is no longer safe to drive on and needs to be replaced. Even just a slight warp in a rim can exacerbate itself over time. This can lead to a total loss of the rim and that is obviously a very dangerous thing. 

Rotating Scion TC Tires 

Generally speaking, tires last about 75 thousand miles or so. Now, keep in mind, that emate is with normal driving. The Scion TC is a sporty car, so there is a high chance that the owner is not going to be driving like a normal person. So, the tires on a Scion Tc might wear out faster than the national average. 

Time is something that wears out tires, too. Most people don’t realize it, but from the moment they are made, those rubber vulcanized tires are slowly breaking down. Eventually, air and moisture has its way with it and the tire needs to be replaced. So, if your tires are older than 5 years old, you should replace them regardless of how many miles are on them.

You should rotate your tires way before your tires need to be replaced. In fact, if you rotate your tires, they will last a lot longer than they otherwise would have been able to. 

For the Scion TC, it’s best to rotate its tires about every 7,500 miles (5000 miles if you drive like a crazy person). The good news is that rotating your tires is really easy to do. All you have to do is move the tires from the left side of the car to the right side of the car while also swapping them front to back. 

Conclusion

The Scion tC is a sporty car made by Toyota that is somewhat of a spiritual successor to the Toyota Celica. The tC was made in two generations spanning 2004 to 2010 and 2010 to 2016, respectively. No matter which generation of the popular car you have, you are going to eventually need to know the Scion TC bolt pattern.

If you have a Scion TC that was made between 2005 and 2010, it has a 5×3.94 inches (5×100mm) bolt pattern and a 2.12 inches (54.1 mm) center bore. If your Scion TC was made between 2011 and 2016, however, then it has a 5×4.50 inches (5×114.3mm) bolt pattern and a 2.37 inches (60.1 mm) center bore. Both generations of the Scion Tc use 5 lug nuts that have a thread size of M12 x 1.25 and a tightening torque of 75 ft lbs. 

We hope this article helped you learn everything that you needed to know about the Scion TC bolt pattern. Thanks for reading!
