Everyone budgets for fuel, tolls and hotels, but almost nobody budgets properly for the four things actually touching the road, and on a European road trip, that’s the mistake that finds you.
Ask a first-time European road tripper what they have budgeted for and you will likely get the same list every time: fuel, tolls, hotels, maybe a breakdown policy if they’ve been reading this newsletter for a while. Tyres rarely make the list, and yet they are the one component with total responsibility for the contact patch between your car and the road, doing it across a thousand miles of conditions a UK MOT test never comes close to replicating, across different surfaces, temperatures, and carrying different weighted loads. Few components are more important than tyres.
This isn’t a piece about tyre brands and which one is best (spoiler: it depends!). It’s about three things worth taking seriously before you leave: 1) what winter tyre law actually requires if you’re touring in ‘shoulder’ or winter season, 2) why I don’t think budget tyres belong on a car doing serious European miles, and 3) what to check beyond the tread depth gauge that (hopefully) everyone already owns).
What winter tyres actually require
The rules in Europe are more specific than “get some winter tyres,” and they differ by country in ways that catch people out.
France — Loi Montagne II
A large number of mountain communes require winter or all-season tyres fitted, or chains carried as the alternative, through the winter period. The detail that trips people up: the familiar M+S marking alone is no longer sufficient. What’s actually required is the three-peak-mountain-snowflake symbol (3PMSF). This is a small pictorial mark on the sidewall, distinct from M+S. A lot of “all-season” tyres sold in the UK carry M+S only, look perfectly compliant to their owner, and aren’t. It is very important to know what your are buying and the rules in the countries you are visiting.
Italy
An obligation applies over a defined winter window on many roads: winter tyres fitted, or chains carried as the alternative. Signage marks the affected sections, but it is easy to miss if you’re not looking for it.
Austria
A mixed situational-and-calendar obligation applies through the winter months in Austria, broadly, if conditions are wintry within the calendar window, you need to be equipped for it.
Germany
Purely situational. The obligation triggers on the conditions on the road in front of you, not the date on the calendar. Driving on summer tyres in snow is an offence in April as much as January, and it also hands your insurer a genuine argument if you have an accident while under-equipped.
Check Before You Travel
Exact dates, affected departments and regions, and the precise marking requirements shift most autumns. Treat everything above as the shape of the rule, not the specific current detail – confirm against each country’s official road authority before you travel, not against another blog.
Why I don’t rate budget tyres for a road trip
This is a personal view, and I’ll say it openly: I don’t think budget tyres belong on a car doing serious European miles, and I’d say that more strongly again for anything classic or performance-oriented.
The reasons aren’t really about outright grip on a dry Tuesday commute, where a budget tyre can be perfectly adequate, if that is your preference. It is what happens at the edges, at the extremes, and a road trip lives at those outer boundaries. A wet Alpine hairpin, a long descent that’s built real heat into the compound over twenty minutes of braking. A fully loaded car with four people and luggage aboard, rather than the near-empty test conditions most reviews are based on. Or what about, as we have had in 2026, a raging hot summer with tyres making contact with hot tarmac for 8 hours straight.
Cheaper compounds tend to lose consistency faster as they heat up and wear, and that’s exactly the margin you’re spending against on a mountain road you’ve never driven before.
Braking distances in the wet open up more than the marketing suggests once you’re outside laboratory conditions and as rubber ages. This matters on a car whose handling characteristics you already know intimately and have tuned your own driving around. A budget tyre quietly changes that relationship, and it only shows up when you actually need to work at the margins of what the tyre can do.
The practical argument is simpler still. You’re planning a two-week trip covering potentially thousands of miles, very possibly in a car worth considerably more than a full set of tyres. Spread across the life of the tyre, the cost difference between a budget and a premium set is genuinely small money set against everything else the trip costs – for the one component that has no backup if it fails.
What to check before you go – beyond tread depth
Tread depth is the obvious check, and most people do it. Two things get missed far more often, and both matter more than a lot of drivers realise.
Sidewall cracking
UV exposure and ozone degrade rubber over time, regardless of tread depth and regardless of how few miles the tyre has actually covered. Look for fine hairline cracks in the sidewall, particularly near the tread shoulder – things like a spider-web pattern rather than a single split. This is a sign of ageing rubber that can fail under load, and heat, speed and a fully loaded car all make the risk worse. It catches out classics and weekend cars especially, since they often do very few miles a year but sit outside, or even just in a garage, ageing the entire time regardless of use. A tyre doesn’t need to be driven to get old.
The date code – on all four tyres, as well as the spare
Every tyre carries a DOT date code on the sidewall: a four-digit number, usually inside an oval, reading as week / year. For example, a tyre marked 2523 was made in the 25th week of 2023. It’s easy to read once you know to look for it.
A tyre with plenty of tread remaining can still be old enough to be a genuine risk. Most independent guidance treats 6 years as the point to start inspecting seriously, and 10 years as an outer limit regardless of how the tread looks. This is a slightly different point to checking your spare’s date code, which is worth doing too. This is about the four tyres actually doing the work, the ones you’re trusting on a wet hairpin 2,000 miles from home. The other reason this is important is lead times. If you need a tyre and you happen to be in rural France at the time, don’t be surprised if a) it isn’t in stock and b) it takes a couple of days at least, to get there. A one week road trip can suddenly become a lot longer!
Before you go – the tyre checklist
- Check tread depth on all four tyres, plus the spare (if you have one)
- Run your hand over each sidewall, not just a glance – cracking is often easier to feel than see
- Read the DOT date code on all four tyres and the spare
- If touring shoulder season or into the mountains, confirm the 3PMSF marking is present, not just M+S
- Check current chain/winter tyre law for every country on your route, not just the one you’ll spend most time in
- Set pressures cold, in the morning, before a long driving day – not after the car’s been sitting in the sun
None of this is complicated, once you know how it works. It’s just the kind of thing that’s easy to skip because a tyre still looks fine, and the whole point of checking properly is that “still looks fine” and “still safe” aren’t always the same claim. Use the experience of many road trips; do not skimp on tyres.
