What happens if I drive my GMC on a flat tire?

Driving on a flat tire is not a good idea. Your G1500 engine will keep running with a flat tire, but you could damage your wheel by continuing to drive on a flat.

Is temporary sealant bad for my GMC's tires?

A temporary sealant may be able to help you get to a repair location safely. But temporary or emergency sealants could possibly damage TPMS sensors, and in some cases may even void the warranty on your Bridgestone or Firestone tires. If your tire needs extensive repair, sealant can add time and labor costs to the process.

What’s the harm in using my spare tire for a while?

While this sounds great in theory, keep in mind that most spare tires are not designed for distance or speed. The compact spare tire that most likely sits inside your 1986 GMC G1500 is intended for only a few days of use, so don’t use it as a substitute for getting your tire repaired.

Where can I get my GMC G1500 tires repaired?

Your local Firestone Complete Auto Care can carry out most GMC G1500 tire repairs, but the extent of the damage will determine if we are able to help.

What is causing the tires on my G1500 to keep losing air?

Possible reasons for your G1500 tires continuously losing air include a leaking valve steam, wheel damage, and a puncture or hole in the rubber.

Do I have to replace all four GMC G1500 tires at the same time?

When replacing the tires on your G1500, it's best to err on the side of caution and replace them in pairs or all four at once. Worn tires can compromise your car's handling and braking, especially if they're paired with newer tires. Refer to your owner's manual to determine whether your vehicle requires all four tires to be replaced if there's a tread difference.

Get Your GMC G1500 Tire Repaired

Urban areas are booming. New roads and buildings are springing up. There's construction around every corner! Unfortunately, this can mean a higher chance of a flat or damaged tire caused by debris in the road. If your 1986 GMC G1500 is in need of a tire inspection or possible flat tire repair, Firestone Complete Auto Care has your back. In some cases, a tire doesn’t have to be replaced – it can be plugged and patched with a simple repair. Depending on the damage, though, a repair might not be the right move. Our technicians can determine which option is best for your situation. To start, we’ll consider the location of tire damage, the type of issue, the size and scope of the damage, and the amount of wear on your tires.

If a repair on your 1986 GMC G1500 tire is feasible and safe, we'll follow three basic steps to repair it: (1) Remove the tire from the wheel for inspection and repair, (2) fill the puncture to keep the moisture out, and (3) secure and seal the inner tire liner to ensure the tire is airtight.

Tire Replacement for Your GMC G1500

Unfortunately, some 1986 GMC G1500 tire damage can’t be effectively repaired. Tires with less than 2/32nd inch tread remaining can't be repaired, no matter how minor the damage. At this tread depth, the tire is worn out and must be replaced. Some tire issues are easy and straightforward to repair, but other kinds of tire damage can’t be properly repaired. Tire damage that can’t be repaired effectively include a tire with a puncture larger than ¼ inch in diameter; a tire with a puncture or damage outside the tread area; a tire with two or more punctures that are less than 16 inches away from each other; and a tire with tread separation or significant cuts.

When your damaged tire can’t be repaired, consult GMC’s recommendations for replacing one, two, or all four of your tires. For vehicles with AWD, manufacturers recommend replacing all four tires simultaneously. This is because the AWD system can only function optimally when all tires are uniform. However, this may not be necessary if your remaining three tires are new. You might be able to replace one tire as long as it's the same brand, type, and size as the other three. Your tire technician can help you decide how many tires to replace and the kind of tire to purchase.

Tire Inspection Services for Your GMC G1500

A flat tire? That’s pretty hard to ignore. But other tire damage? It’s not always obvious! Inconspicuous issues like bulging sidewalls, exhaust noise, leaks, or bent rims may indicate issues that need immediate attention. Stay ahead of potentially dangerous tire issues. Bring your 1986 GMC G1500 in for a tire inspection.
