Why should tires be your first stop before a long drive?
Whether you're heading down I-45 to Galveston, west on I-10 toward San Antonio, or northwest on US-290 to Austin, your tires take on extended highway speeds and summer heat that differ significantly from everyday city driving. Check tread depth with a quarter, inspect for uneven wear patterns, and confirm tire pressure matches the specification on your driver's door jamb, since underinflated tires are a leading cause of highway blowouts.
Don't forget to check your spare tire or inflator kit, and consider having any marginal tires replaced before the trip rather than risking a roadside tire failure on a high-speed stretch of highway far from home.
Which fluids need to be checked before a highway trip?
Engine oil, coolant, transmission fluid, brake fluid, and power steering fluid should all be inspected before extended highway driving, since sustained highway speeds generate more heat than typical city commuting. Low coolant is particularly risky on a hot drive through the Texas Hill Country toward Austin, where extended climbs can push engine temperatures higher than usual.
If your oil change is due within the next 1,000 miles, it's worth having it done before the trip rather than during it, since fresh oil provides better protection under the sustained high RPMs of highway driving.
What should you check on your brakes before a long drive?
Winding roads through the Hill Country on the way to Austin or San Antonio demand responsive, reliable brakes, and heavy traffic on I-45 near Galveston on weekends means frequent stop-and-go braking. Have your brake pads, rotors, and fluid inspected, listening for grinding or squealing noises and checking for a soft or spongy brake pedal that may indicate air in the lines or worn components.
If your brakes are nearing the end of their service life, it's far better to address it before a 200-plus mile trip than to discover the problem on the road.
Should you check the battery and belts before departure?
A battery that's marginal in city driving can fail outright under the combined stress of highway vibration, AC use, and summer heat on a long trip. Have the battery load tested, and visually inspect the serpentine belt for cracking or glazing, since a snapped belt on a remote stretch of highway between Houston and San Antonio can leave you stranded without power steering or a functioning alternator.
It's also worth checking hoses and belts under the hood for any soft spots, bulges, or fraying that indicate they're near the end of their service life.
What should be in your emergency kit for the drive?
Pack a basic emergency kit including a flashlight, jumper cables or a jump pack, a tire inflator or plug kit, drinking water, a phone charger, and a reflective triangle or flares, particularly important for trips that pass through more remote stretches between major Texas cities. Cell coverage can be spotty in parts of the Hill Country, so knowing your route and having a charged phone is essential.
It's also wise to save the number for a mobile mechanic service before you leave, so if something does go wrong, you can get help quickly rather than searching while stranded on the shoulder.

Frequently asked questions
How far in advance should I get a pre-trip inspection?
Ideally, schedule it two to three days before departure, giving enough time to order parts if a repair is needed.
What does a pre-trip inspection typically cost?
A thorough pre-trip inspection generally costs between $80 and $150, depending on the depth of the check and your vehicle type.
Is it necessary to check tire pressure if the tires look fine?
Yes, tires can look normal while still being significantly underinflated, which increases blowout risk at sustained highway speeds.
What if my car breaks down on a remote stretch of highway?
Call our 24/7 emergency roadside service, we can dispatch a technician to most locations within our Houston-area service radius.
