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

A flat tire that’s not addressed can take a terrible toll on the rest of your car. Until you have it repaired or replaced, drive your LS400 as little as possible to reduce your risk of damage to the wheels and alignment – or further damage to that already struggling tire!

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

Temporary sealants will solve your problem… for a little bit. If you’ve seen temporary or emergency tire sealant before (it usually comes in a can), it can be tempting to turn to this as a solution for your flat tire. Keep in mind that these fixes could buy you some time to get to Firestone Complete Auto Care for a proper repair, but they could also cause some harm in the process (for example, damage to your TPMS). Plus, using a product like this could void your tire warranty.

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

Don't rely on your spare tire for too long. Your 1990 Lexus LS400 may come equipped with a compact spare tire. A spare is different than an everyday tire and is only designed to be driven a certain number of miles at lower speeds.

Who repairs Lexus LS400 tires?

Your nearest Firestone Complete Auto Care is equipped to handle most Lexus LS400 tire repairs, but it depends on how severe the damage is.

Why do my LS400 tires keep losing air?

Possible reasons for your LS400 tires continuously losing air include a leaking valve steam, wheel damage, and a puncture or hole in the rubber.

Is it necessary to replace all four Lexus LS400 tires at once?

Replacing all four tires on your LS400 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”.

Repairing Your Lexus LS400 Tire

City populations are exploding. Roads are expanding. Everywhere you look, it seems construction is in progress! 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 1990 Lexus LS400 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. We'll start by evaluating the state of wear, the location of damage, type of damage, and the size of the damage.

If a repair on your 1990 Lexus LS400 tire is feasible and safe, we'll follow three basic steps to repair it: (1) Take the tire off the wheel for easy inspection, (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 Lexus LS400

Unfortunately, some 1990 Lexus LS400 tire damage can’t be effectively 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). Tires with this tread depth or less are no longer safe, so it’s time to replace the damaged tire. If your tire is not yet worn down, there are other forms of damage that simply can’t be repaired, like a tire puncture with a diameter bigger than ¼ inch; a puncture in the tire sidewall (or anywhere else that’s not within 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.

When your damaged tire can’t be repaired, consult Lexus’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. 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.

Lexus LS400 Tire Inspection

Some tire issues can cause you to have a flat, but other damage isn't so noticeable right away. Tire damage can also show itself through subtle symptoms, like dents in your wheel rims, excessive noise coming from the exhaust system, bumps or bulges in tire sidewalls, or even leaks underneath the car. Stay ahead of potentially dangerous tire issues. Bring your 1990 Lexus LS400 in for a tire inspection.
