A 1991 Chevrolet S10 has a 5x4.76 or 5 on 4.76 bolt pattern, which means that all four wheels have five bolts each, arranged in a circle measuring 4.76 inches in diameter.
What the 1991 Chevrolet S10 lacks in fuel efficiency and carrying capacity, it makes up for in power and reliability, landing it a well-earned spot in the pantheon of classic Chevy pickup trucks. So while you may not need to make many intensive repairs, replacing the stock wheels with something a little more sturdy and stylish can't hurt.
1991 Chevrolet S10 bolt pattern
Every 1991 Chevrolet S10 has a 5x4.76 or 5 on 4.76 bolt pattern—of course, if you’re not particularly well-versed in vehicle lingo, that might not mean anything to you. If that’s the case, don’t fret—every lug pattern essentially indicates the following:
# of bolts x diameter of the circle they form
This means any vehicle with a 5x4.76 bolt pattern will have five bolts arranged in a 4.76-inch diameter circle securing each wheel.
That said, you’ll need to know more than just the lug pattern to replace your 1991 Chevy S10’s wheels, namely the wheel size, stud size, offset, center bore measurement, and the manufacturer’s torque specifications:
How to measure your Chevrolet S10’s bolt pattern
With the information listed above, you should have no problem switching out your Chevy S10’s wheels—but if you want to check the measurements for yourself, you can quickly figure out your vehicle’s lug pattern with a measuring tape or even just a ruler.
All you need to do is grab your measuring device, head out to your car, pick a bolt to start from (any will do), and measure from the lug hole’s outer edge to the center of the bolt on the opposite side. Since the 1991 Chevy S10 has an odd number of bolts, you’ll end up between two if you measure straight across, so you’ll have to measure to the center of either of the closest bolts.
Whatever number you end up with will be the circle’s diameter—put that together with the number of bolts, and you’ll have found your 1991 Chevrolet S10’s bolt pattern.
