Can I drive my GMC on a flat tire?

Driving on a flat tire is not a good idea. Your C1500 engine will keep running with a flat tire, but you could damage your wheel by continuing to drive on a flat.

Will a temporary sealant fix my GMC's flat tire?

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.

How long can I drive my GMC on a spare tire?

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 1985 GMC C1500 is intended for only a few days of use, so don’t use it as a substitute for getting your tire repaired.

Who can repair GMC C1500 tires?

Your nearest Firestone Complete Auto Care is equipped to handle most GMC C1500 tire repairs, but it depends on how severe the damage is.

What is causing the tires on my C1500 to keep losing air?

If your C1500 tires are always losing air, you may have a puncture, damaged wheel, or leaking valve stem.

Is it necessary to replace all four GMC C1500 tires at once?

Replacing all four tires on your C1500 is not always necessary. However, it is recommended that you replace tires in pairs or all four tires at the same time for safety and performance reasons. If you have two new tires and two worn tires, the worn tires may not grip the road as well as the new tires, which could cause your car to slide or lose control. Always refer to your vehicle owner’s manual since some vehicles require you to replace all four tires if there is a tread difference greater than 3/32”.

GMC C1500 Tire Repair

Cities are growing. New roads are being built, and old ones are getting a face lift. 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 the road has been rough on your 1985 GMC C1500 tires, Firestone Complete Auto Care can help. Our tire technicians can determine whether it's safe to plug and patch the tire, or whether it needs to be replaced. 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 we determine that your 1985 GMC C1500 tire can be safely repaired, the repair process is actually fairly simple: (1) Separate the tire from the vehicle wheel, (2) fill the puncture to keep the moisture out, and (3) secure and seal the inner tire liner to ensure the tire is airtight.

GMC C1500 Tire Replacement

Not all 1985 GMC C1500 tire damage can be repaired. Even if your tire damage is minor, if your tires have less than 2/32nd inch of tread remaining, a repair isn’t possible (or safe). At this tread depth, the tire is worn out and must be replaced. If your tire is not yet worn down, there are other forms of damage that simply can’t be repaired, like 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 major cuts or separated treads.

Depending on what GMC recommends for your car, you’ll want to consider purchasing one new tire, two new tires, or a new full set. For example, it’s usually recommended that you replace all four tires at the same time on AWD vehicles. Why? Because having four identical tires is vital for the AWD system to perform like it’s supposed to. But, if you’ve recently replaced your tires and they don’t have significant wear, a new set might not be needed. If you can replace your damaged tire with the same type, brand, and size as the others, you may be able to save costs and only purchase one replacement. Your tire technician can help you decide how many tires to replace and the kind of tire to purchase.

Do I Need a Tire Inspection for My GMC C1500?

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. Bring your 1985 GMC C1500 in for a tire inspection so we can assess the damage and help keep you safe on the road.
