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:
  • Factory wheel size: 14 - 15 inches
  • Stud size: M12 x 1.6
  • Offset: 14 to 50 mm
  • Center bore: 70.3 mm
  • Wheel tightening torque: 129 Nm

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.

How to optimize your Chevy’s insurance coverage

Switching out the factory-issued wheels in your 1991 Chevy S10 for a better set of aftermarket rims is one of the
easiest vehicle modifications
you can make. However, any time you significantly upgrade your vehicle, you should also upgrade your Chevy car insurance policy. 
This is largely because modifying your Chevy increases both its value and its risk of theft. Going forward, make sure your policy has
comprehensive coverage
and inform your agent of any modifications. Now is also the perfect time to shop for a
