Does Cadillac CT5 Have A Spare Tire? (Explained)

It is impossible to predict when your tire may go flat, hence the need for a spare tire.

It always comes in handy. Some vehicles have spare tires while others don’t.

So, to prevent the extra cost of buying a spare, potential buyers may wonder if the Cadillac CT5 has a spare tire?

The classic Cadillac CT5 Sedan doesn’t come with a compact spare tire for emergencies. Instead, it features all-season run-flat or self-repair tires. These tires are deflation resistant and can carry on for 50 miles after a puncture.

Do Cadillacs Come With a Spare Tire

The reputable GM motors brand is famous for its numerous achievements. However, spare tires aren’t one of the famous properties of modern Cadillacs.

Therefore, since 2016, automobile makers have decided to diss spare tires like other automakers and give out other offers. 

The unavailability of spare tires lessens the weight of cars, thereby positively impacting fuel economy and mileage.

Thus, modern Cadillacs no longer offer spare tires. While some people may mourn the demise of a spare tire, there’s no need for that.

Cadillac won’t remove a feature without replacing it with an equally efficient or a better feature. 

So, Cadillac offers tire inflation kits and all-season run-flat tires to compensate for the lack of spare tires.

Interestingly, these are just as good as spare tires as they keep you on the road for a considerable amount of time before a fix. 

So, with the inflation kits, compressants, sealants, and all-season run-flat tires, you’re still good to go even after encountering punctures. 

Does Cadillac CT5 Have a Spare Tire?

No, CT5 doesn’t have a spare tire. Instead, the 2021 Cadillac CT5 has 19-inch run-flat or 18-inch self-repair wheels produced by Michelin.

These sport profile tires are comfortable & efficient and make for a nice ride. 

These run-flat tires have a steady, powerful grip. They are also highly resistant to air pressure. So, they are fit to serve the luxury, premium luxury, and Sports trims. 

You can drive a punctured Run-flat tire for 50 miles at a maximum speed of 55mph.

When driving with a run-flat tire, it is best to monitor the tire pressure with the TPM system. Consult the Cadillac owner manual for more details.

Cadillac CT5 Spare Tire Location 

Since we have established that the CT5 does not offer the luxury of spare tires, there is no designated space for one.

Therefore, in the aspect of space, priority was given to the interior more than the cargo. So, the trunk space is quite tight compared to that of other Sedans. 

What this means is that there is no cargo space for a spare tire. Normally, in Cadillacs with spare tires, the tires are usually located beneath the floor lid in the trunk. 

But with the Cadillac CT5, even if you lift the floor lid in the trunk, you still won’t find a spare tire. So instead, what you will find there is the re-inflation kit.

The components of the kit are an air compressor with power cables & built-in hoses alongside a sealant.

The efficiency of the kit is highly rated, and it will see you through most flat tire issues till you can get help. 

Although there is an inflation kit, it would be wise to take extra safety measures.

For example, you can invest in roadside assistance to ensure that you won’t be stranded in the middle of anywhere.

Uses of Spare Tire

A spare tire is a traditional way for manufacturers to provide it ahead of time for tire mishaps. You can never tell when your tire will run flat or encounter issues.

But, if it does, you can always stop and change it. 

However, manufacturers realized that not everybody has the manual knowledge of changing tires over time.

And for some, it may simply not be convenient. For example, if your tire runs flat when it’s raining, you wouldn’t appreciate getting down to change it.

So, due to this, a decision was made to upgrade or swap spare tires with run-flat tires.

Run-flat tires offer you all the convenience of spare tires without getting your hands dirty. 

The tires are made with materials that can resist deflation and keep you going for a couple of miles.

Also, the instructions for use are similar. They are just as useful and important as spare tires, and you should be glad to have them.

How Long Can You go on a Spare Tire?

A Cadillac compact spare tire is an emergency tire. Therefore, it’s not suitable for long distances. It can be driven between 50 to 70 miles per hour.

However, it shouldn’t exceed 70.

The more miles you go with a donut tire, the more the traction diminishes. For your donut tire to serve you, it has to be in good shape.

Therefore, ensure it is serviced whenever you go for tire maintenance.

Pros and Cons of Having a Spare Tire

A spare tire is a must-have, be it an OEM (Original Equipment Manufacturer) or an aftermarket spare.

A Cadillac CT5 having no spare tire provision doesn’t stop you from purchasing an aftermarket product.

If you’re still considering this, let me give you a rundown of the pros of having a spare tire.

  • Spare tires serve as a swift alternative for replacement in an emergency. They also offer more guarantees than sealants and inflation kits.
  • If you ever have a flat tire, all you need to do is switch to the spare and drive to a repair shop.
  • A compact spare ensures that the tread of the tire wears out in the same ratio as you have to change it to a full-size tire after certain miles.
  • The size of the compact tire lessens the weight of the car and enhances speed.

A spare tire is an anchor to keep you at bay from danger. However, this doesn’t mean there aren’t little inconveniences with using a spare tire. 

Here are the cons of spare tires:

  • You cannot continually use a compact spare tire as it is only meant for emergencies. Using it for a prolonged time puts you at risk.
  • The extra weight added to a vehicle by a spare tire slows your car down while driving.
  • It is smaller and narrower than a full-size tire and can thus cause instability or loss of traction if not maneuvered carefully.

I prefer having a run-flat tire to a spare tire. Why? There’s no need for me to face dirt and grit while changing tires with a spare tire kit.

So, it would be best if you were content with your CT5’s run-flat tires because they’ll come through for you any day, any time.
