While useful, that is not all the information that you need to know. In this article, we will go over the Chevrolet Corvette C5 bolt pattern in more detail for each generation. We will also give you links for the exact lug nuts to use on your Chevrolet Corvette C5. Then, we will discuss the center bore and torque specs for each generation in detail.

Chevrolet Corvette C5 Bolt Pattern
Unlike a lot of the cars we cover on this website, the Corvette C5 does not have very many configuration options. This makes sense because the Corvette is definitely not an average vehicle. It’s a very specific vehicle that has a more purposeful default configuration than most vehicles.
With that being said, there is still a lot to learn about the subtle variations between Corvette C5 version.
|Year Range||Bolt Pattern||Center Bore||Lug Nuts||Thread Size||Torque Specification|
|1997 – 2004||5×4.75 inches(5×120.65mm)||2.77 inches(70.3 mm)||5||M12 x 1.5||100 ft lbs|
Chevrolet Corvette C5 Wheel Fitment Guide
If you are going to mount a wheel on your muscle car, you’re gonna need to know more than the center bore diameter, wheel tightening torque, lug nut size, and the thread size of the bolts. You will also need to know all of the tire and rim options that came with each engine configuration of each Chevrolet Corvette C5 generation.
1997 – 2004
All versions of the Corvette C5 for this range of years uses a massive 5.7 L V8 engine, but they all come in different power ratings and therefore use different tire sizes. If your C5 the 345 HP or 350 HP engine, it uses a tire size of 245/45ZR17 mounted on a 8.5Jx17 ET58 rim.
If, on the other hand, you use the significantly more powerful 405 HP engine, your C5 will use a tire size of 265/40ZR17 and a rim size of 9.5Jx17 ET54.
|Engine Size||Horse Power||Tire Sizes||Rim Sizes||Bolt Pattern|
|5.7L V8||345 HP||245/45ZR17||8.5Jx17 ET58||5×4.75 inches(5×120.65mm)|
|5.7L V8||350 HP||245/45ZR17||8.5Jx17 ET58||5×4.75 inches(5×120.65mm)|
|5.7L Z06 V8||405 HP||265/40ZR17||9.5Jx17 ET54||5×4.75 inches(5×120.65mm)|
Properly Tightening The Bolts
The Chevrolet Corvette C5 uses 5 lug nuts that need to be tightened in a specific, crisscross pattern. This information can of course be found in the Chevrolet Corvette C5 user manual, but it’s nice to have everything all in one place.
Please make sure to take the time to properly tighten your nuts. Remember, if you tighten them too much, it will end up damaging components and make the wheel nearly impossible to remove next time. In contrast, if you don’t tighten the lug nuts enough, well, I’m sure you can use your imagination with that one.
The first step is to tighten the lugs with a hand wrench. Make sure not to tighten the lug nuts down all the way just yet. If you do, it won’t be possible to get all of your lug nuts torqued down to their proper level. So, just tighten them down about half way at first to get them all on.
Then, you are gonna need a proper torque wrench so you can tighten your Chevrolet Corvette C5 lug nuts to the appropriate amount of pressure. For the C5, the lugs need to be tightened down with 100 ft lbs of pressure.
After that, we highly recommend that you perform a travel test on your Chevrolet Corvette C5 lug nuts. A travel test is easy and is good for safety. Doing this is easy. All you have to do is tighten your C5 lug nuts 100 ft lbs and then drive for around 30 miles or so.
Then, just check the torque on each of your lug nuts again. If any of them are loose, re-tighten them. Repeat the travel test and if any of your lug nuts are loose, then that means that the rim is warped and needs to be replaced.
When To Rotate Chevrolet Corvette C5 Tires
Tires generally last about 75,000 miles or 5 years, whichever comes first. I know it may seem counterintuitive that the age of your tires can affect their health. The unfortunate fact of the matter is that after a few years, tires will begin to dry rot. Once this process gets to a certain point, tires are no longer safe to drive on and need to be replaced.
It’s never a good day when tires have to be replaced. The good news is if you rotate your Chevrolet Corvette C5 tires at regular intervals, they are going to last way longer than they otherwise would have. The reason tires need to be rotated is because the wheels in a car are not mounted 100% perfectly straight and parallel to each other. Manufacturers try their absolute best to do this, but it’s basically impossible with today’s technology.
For your Chevrolet Corvette C5, make sure to rotate the tires every 7,500 mile. Doing this will ensure that your tires have the longest possible life. The process of rotating tires is not at all a difficult one. All that needs to be done is the rear tires have to be moved to the front and the front tires need to be moved to the back.
In the process, make sure to always swap the tires from left to right. That’s really all there is to rotating your tires.
