We’ve written extensively about Buick and the numerous questions you can have about this brand. Today, we will talk about the information you need to have to select the correct new tires or rims for any Buick. Specifically, we’ll look at the bolt pattern of each model and generation. Let’s start with a quick answer:
Buick makes use of four different bolt patterns in their cars. Recent generations have had a 6×4.72 inch (Enclave), 5×4.13 inch (Encore), 5×4.53 inch (Encore GX, LaCrosse, Regal), or 5×4.72 inch (Envision) bolt pattern.
However, that certainly doesn’t tell the whole story. Below we’ve outlined the bolt pattern in more detail for each generation. We also discuss what lugs/bolts are used precisely, the center bore hub’s diameter and the bolts’ torque specifications. Finally, we also have information about each engine type and its exact tire and rim size. You should know precisely what you can and cannot buy this way. Read on!

Buick Regal
Buick Regal, manufactured between 2009 – 2013 and 2018 -2020, have a bolt pattern of 5×4.53 inches (5x115mm), a center bore of 2.77 inches (70.3mm), and five lug nuts with a thread size of M14 x 1.5 (´09-´13) or M12 x 1.5 (´18-´20) that need to be tightened with 110 lb-ft (150Nm) of force.
Buick Regal, manufactured between 2014 – 2017, have a bolt pattern of 5×4.72 inches (5x120mm), a center bore of 2.77 inches (66.9mm), and five lug nuts with a thread size of M14 x 1.5 that need to be tightened with 110 lb-ft (150Nm) of force.
Retightening The Bolts
As said before, all Buick that we discussed have five lug nuts (except for the Enclave, which has six). When you mount the wheel to the car again, these need to be secured in a specific way. This information is stated in the owner’s manual, but we’ve gone through the effort of instructing you here. Buick advises you to bolt these nuts in the way shown below. You have to follow a crisscross pattern.
In the second round, you tighten them with the wheel wrench to the appropriate lbs-ft or Nm we stated earlier.
It’s expected that your wheel also have a center cap or cover. These need to be secured in the same pattern. Please tighten them first-hand snug with your hands. Then, use the wheel wrench to tighten them another one-quarter turn.
It’s also important to check if the lug nuts are still secured after 30 miles (48 kilometers). Please ensure they are all in place and tightened with the proper force. If not, tighten them again and recheck. If this keeps happening, you’ll need to replace the wheel.
When Or Why To Rotate/Change Tires
Suppose you’re changing your tire. You also need to know when to change or rotate it precisely. Let’s first talk about changing your tires. Tires usually last around 60,000 – 75,000 miles or 4-5 years. After this period, they need to be replaced. Sometimes this happens earlier, so it’s a good idea to keep an eye on the tread wear indicators. These are shown in the image below. These indicators show when the tires have only 1.6 mm (1/16 in) or less tread remaining.
Another occasion you’ll need to take off your tires is when you’re rotating them. In the owner’s manual of Buicks, it’s said that this needs to happen every 7,500 miles or 12,000 kilometers. It’s advised you rotate the tires in the exact way that’s shown below. The front tires are moved to the back, and the front tires move crisscross to the front.
