The Best Tyre Sizes to Always Keep in Stock (And Why They Matter)
🕒 Reading time: 4 minutes
If you’ve ever said “Sorry, I’ll have to order that in,” you already know this:
Stock = speed. Speed = more sales.
Whether you run a busy tyre shop, an MOT centre, or you’re a general mechanic who only fits tyres occasionally, having the right few sizes on your rack means you don’t lose time or money when someone’s in a rush.
This post breaks down the most common UK tyre sizes worth keeping in stock — and how to decide what makes sense for your garage.
📈 Why Bother Keeping Stock at All?
Even if you don’t do tyres every day, having a small batch of best-sellers on hand can:
- Help you win same-day jobs
- Make your garage look more professional
- Avoid delays or delivery costs
- Turn browsers into buyers
It’s not about having everything — it’s about having the right few.
🔟 The Most Common UK Tyre Sizes (As of 2024–2025)
Here are 10–15 car sizes that cover a large chunk of UK vehicles:
- 205/55R16
- 195/65R15
- 225/45R17
- 195/55R16
- 185/65R15
- 175/65R14
- 215/55R16
- 225/40R18
- 225/50R17
- 215/45R17
- 215/60R16
- 185/60R15
- 205/60R16
- 205/50R17
- 175/70R13
These sizes are commonly fitted to popular models like VW Golf, Ford Focus, Audi A3, BMW 1 Series, Nissan Qashqai, Vauxhall Corsa/Astra, and others.
Even keeping 1–2 tyres of each can cover a surprising number of jobs.
🚚 High-Demand Van Sizes (if you work with trades)
If you regularly serve builders, couriers, or small fleet vans, consider adding:
- 195/70R15C
- 215/65R16C
- 235/65R16C
- 225/70R15C
These are popular on vans like the Ford Transit, Mercedes Sprinter, Vauxhall Vivaro, etc.
Even MOT stations who don’t do a lot of vans may find it useful to keep one van size for emergencies.
❌ What to Avoid Unless You’re a Tyre-Focused Shop
If you’re tight on space or cash, you can skip:
- Run-flats (RFTs) — niche and expensive
- 20”+ sizes — for high-end or rare vehicles
- Oddball specs — like 165/70R14T XL or 235/55R19
- Winter tyres — unless you’re in a very cold or rural area
If you get asked, order them in — but don’t tie up space or money.
💡 If You Can’t Keep Stock, Do This Instead
Don’t want the hassle of stock? Still want to look sharp?
- Build a relationship with a fast local wholesaler (like us at Tyreroom)
- Keep a small display rack for show — even if most orders are same-day
- Use the phrase:
“We’ve got that size available for this afternoon — want to book it in now?”
It still feels fast and professional — without needing shelves full of rubber.
Final Thought
Having the right tyres in stock can make or break a sale.
You don’t need a warehouse. You just need a smart little selection.
Start with your 5–10 fastest sizes — and watch how many more jobs you say “yes” to.
