I recently drove from Spain to Romania and back, which sounds wonderful when I talk about the places I visited and considerably less wonderful when I talk about what it did to my car… and my bank account.

There is a side to road trips that doesn’t feature quite so heavily in the Instagram posts. Thousands of kilometres mean tyres wear down, service intervals arrive far sooner than you’d like, and all those potholes, mountain roads and questionable surfaces eventually take their toll. I know this particularly well because I managed to wear through both of my front tyres much earlier than I should have.

The culprit, as I eventually discovered, was the tracking. My wheels weren’t properly aligned (thanks to a pothole), I hadn’t noticed, and by the time I did, the uneven wear meant both front tyres needed replacing. An expensive lesson, but a useful one: when you’re putting serious mileage on a car, small problems can become expensive ones surprisingly quickly.

The same applies whether you’re driving my car or an Audi A3. Drivers looking for dependable tyres for their Audi A3 often make Magowan Tyres their first stop. Regardless of where you buy your tyres, though, there are a few things I would now pay considerably more attention to before setting off on another big road trip.

How a Season of Road Trips Can Take Its Toll on Audi A3 Tyres

Long Road Trips Add Up Faster Than You Think

One long drive might not seem particularly significant, but a season of road trips can add thousands of kilometres to your mileage surprisingly quickly. My Spain-to-Romania trip made this painfully obvious. Not only did my tyres suffer, but my service intervals seemed to come around at a speed that neither I nor my bank account particularly appreciated.

Tyre wear is influenced by several factors, including driving style, vehicle load, tyre pressure, road surface and temperature. There isn’t a magic number of road-trip kilometres after which your tyres suddenly need replacing. But the more distance you’re covering, the more worthwhile regular checks become.

And looking at a tyre and thinking “that seems fine” isn’t really an inspection, something I have learned the expensive way. Tread depth can be measured, while cuts, bulges and other visible damage should be checked properly. If anything looks unusual or you’re unsure about the condition of a tyre, getting it inspected professionally is much better than discovering the problem several hundred kilometres from home.

Not All Road-Trip Roads Are Created Equal

Some of my favourite places have involved roads that were considerably less impressive than the destination. Get away from major towns and motorways and you can quickly find yourself dealing with broken tarmac, gravel, potholes and narrow rural roads where getting two cars past each other feels like an exercise in advanced spatial awareness.

Potholes are particularly easy to dismiss. You hit one, swear loudly, apologise to your car and carry on driving. But a sufficiently hard impact can affect wheels, tyres or alignment, and you might not immediately realise something has changed.

That brings me neatly back to my two prematurely deceased front tyres.

I hadn’t noticed that my tracking was out. The car was still driving, there hadn’t been one dramatic incident where I immediately thought something was wrong, and I carried on putting kilometres on it. Unfortunately, the tyres were wearing unevenly the entire time. By the time the problem became obvious, correcting the alignment wasn’t going to resurrect the rubber I’d already lost.

One thing worth checking, therefore, is whether the tread is wearing evenly across each tyre. Feathering, where one side of the tread blocks feels smoother and the other sharper, can sometimes be associated with alignment problems. Uneven wear can have several causes. So if you notice it, have the car checked rather than attempting to diagnose it yourself.

Had I done that earlier, I might have saved myself the cost of two tyres.

Check Your Tyre Pressure Before a Long Journey

This is where I’m supposed to tell you that checking your tyre pressures is a quick and easy job that everyone should routinely do.

Which it is.

I’m slightly less qualified to be smug about it because I once realised I’d left mine far too long, drove to a machine to finally sort them out and proceeded to use it incorrectly. Instead of putting air into my tyres, I managed to let air out.

Not my finest motoring moment. And yes, a man did have to come and rescue me which hurt more than I’d like to admit.

Once you’ve established which direction the air is supposed to be travelling, however, correct tyre pressure matters for handling, braking, tyre wear and fuel efficiency. It’s particularly important when you’re heading away with a car full of passengers and luggage. Under-inflated tyres can generate additional heat and wear, while incorrect pressures can also affect how the car handles.

Don’t assume the pressure you normally use is automatically correct when your car is fully loaded either. Audi’s recommended pressures can vary depending on the specific A3 model, tyre size and vehicle load, so check the information provided for your particular car, usually on the vehicle information label and in the owner’s manual.

And perhaps read the instructions on the air machine before enthusiastically attaching things to your tyres.

Give Your Tyres a Proper Check After a Busy Travel Season

We tend to think about preparing a car before a road trip, but I’ve become considerably more aware of what needs checking afterwards too. A big road trip doesn’t finish affecting your car simply because you’ve unpacked your suitcase.

After driving from Spain to Romania and back, I’d clocked up thousands of additional kilometres. That meant more tyre wear, but it also brought routine servicing around much sooner than I was used to. Nothing was necessarily “wrong” with the car; I’d simply asked it to do a lot of driving in a relatively short period.

Start with the basics. Check the tread depth across each tyre rather than in just one place, look for uneven wear and inspect the sidewalls for obvious cuts, cracking, bulges or other damage. If you’ve hit a particularly memorable pothole during your travels, it may also be worth having the wheel and alignment checked.

Pay attention to how the car feels as well. If it starts pulling to one side, the steering wheel sits differently when travelling straight or you notice a new vibration, don’t simply assume it is one of those things. Those changes are worth investigating before setting off on another substantial journey.

Tread Depth Matters Even Before You Reach the Legal Limit

There are really two different questions when looking at your tyres: Are these tyres legal? and Are these the tyres I want to start another enormous road trip with?

Those aren’t necessarily the same thing.

Legal minimum tread depths vary depending on where you’re driving, which becomes particularly relevant on a European road trip where you may cross several borders. You should always check the requirements for every country you’ll be driving through rather than assuming the rules at home apply everywhere.

Tyre performance also changes as tread wears. Wet-weather performance is particularly relevant because the tread needs to disperse water from beneath the tyre, and its ability to do that changes as the tyre becomes more worn.

That doesn’t mean there’s one universal tread depth at which every Audi A3 tyre should automatically be replaced. Tyre design, condition, age, driving conditions and the journey ahead all matter. If your tyres are approaching their limits and you’re planning another long trip, particularly somewhere where rain or difficult road conditions are likely, getting them professionally assessed makes much more sense than relying purely on whether they’re technically still legal.

Don’t Forget About Tyre Age

Mileage and tread depth aren’t the only things worth considering. Tyres also age, and rubber can deteriorate over time even if the car isn’t covering enormous distances. How quickly that happens depends on factors including storage, climate, usage and the tyre itself, which is another reason condition matters alongside tread depth.

You can find a tyre’s manufacturing date marked on its sidewall as part of its identification code. If you’re unsure how old your tyres are or whether their age is becoming a concern, a tyre professional can inspect them and advise based on their actual condition rather than simply assuming low mileage means they’re fine.

This can be particularly relevant if you’ve bought an older second-hand Audi A3. You might know exactly how many kilometres you’ve driven, but unless you have good records, you may know considerably less about the history of the tyres already fitted to it.

Before the Next Road Trip

I’d still rather spend my road-trip planning time finding interesting places to stop, local restaurants to try and unnecessary detours to add to the route than thinking about tyre pressures and wheel alignment. Unfortunately, my Spain-to-Romania road trip has taught me that ignoring the boring bits can become rather expensive.

So before the next big trip, I’ll be checking the pressures against the manufacturer’s recommendations, measuring the tread, looking for uneven wear and paying considerably more attention to the alignment. I’ll also be keeping an eye on how much mileage I’m adding and accepting that servicing a heavily travelled car is simply another cost of travelling this way.

And when I next use an air machine, I’ll make absolutely certain I’m putting air into the tyres.

We live and learn.
