Tyre guide
How to check your tyre size before buying
Before you compare tyres, check the exact size, load index and speed rating on your current sidewall or vehicle placard so you avoid ordering the wrong fit.

Read the sidewall first
A tyre size code such as 245/45 R18 tells you three important things: the width, the profile and the rim diameter. But it does not tell you everything you need for a safe replacement. The load index and speed rating sit separately from the size code, so a tyre can match the dimensions and still be wrong for the vehicle if those markings do not line up. For van tyres especially, check the full marking on the current sidewall before comparing options such as the Dunlop Econodrive AS 185/75 R16 104/102R, 195/60 R16 99/97T or 195/65 R16 104/102T.
Check the vehicle placard as a second source
The same car model can use different tyre sizes depending on trim, wheel option and market, so the vehicle placard or handbook is a useful second check rather than a formality. If the sidewall and vehicle label do not agree, do not assume a near match will do. Confirm the approved size for your exact vehicle and wheel setup before ordering, because tyre size is not universal across every version of a model. That caution matters even more when you are choosing between similar-looking examples from the same brand family.
Use season and van markings as secondary filters
The three example tyres on this page are all Dunlop Econodrive AS all-season van tyres, with visible prices from £103.58 to £114.67. That makes them a comparison set rather than a winner list. Once fitment is confirmed, compare whether the all-season label suits your year-round driving and whether the load and speed markings match your van’s needs. Because no visible ratings or review counts are supplied for these examples, the safest approach is to compare size first, then load and speed, then price and the latest retailer details.
What the wider research shows
The page combines shortlist data, public topic research and retailer details so the advice is more than a generic buying guide. The strongest detail comes from product names, current prices, available variants and retailer-visible specifications. 3 public or retailer sources informed the page, and unsupported claims are left as things to verify rather than stated as facts. Use Econodrive AS 185/75 R16 104/102R All season (£111.06), Econodrive AS 195/60 R16 99/97T All season (£103.58), Econodrive AS 195/65 R16 104/102T All season (£114.67) as practical reference points before checking the latest retailer page.
How to turn the advice into a shortlist
The decision is less about finding a universal winner and more about matching price spread (£103.58-£114.67), tyre type (Van tyre), brand context (Dunlop) and tyre sizes and stock to the shopper's actual need. Compare Econodrive AS 185/75 R16 104/102R All season (£111.06), Econodrive AS 195/60 R16 99/97T All season (£103.58) first, then check whether a cheaper or dearer option changes the specification enough to matter. Before buying, verify live price, delivery cost, stock status and the details that matter for your use case.

Firmness questions
Can the same car model use different tyre sizes?
Yes. Trim, wheel size and market can change the correct tyre size, so the sidewall and the vehicle placard should be checked together before you buy. Never assume every version of the same model takes the same tyre.
What do the numbers and letters on a tyre sidewall mean?
A code such as 245/45 R18 shows width, profile and rim diameter. The load index and speed rating are separate markings, and they matter just as much when you are replacing tyres, especially on vans or heavily loaded vehicles.
Should I choose all-season tyres straight away?
Only after fitment is confirmed. All three example products here are Dunlop Econodrive AS all-season van tyres, so season is a useful second filter, but the exact size, load index and speed rating still have to match your vehicle first.
Why do load index and speed rating matter as much as tyre size?
Because size alone does not tell you whether the tyre is suitable for the vehicle’s intended use. The load index and speed rating are separate markings, and for vans they are particularly important alongside the size code.
How do I know if a van tyre has the right load rating?
Check the load index shown on the sidewall and compare it with the vehicle placard or handbook. If you are unsure, do not rely on the size code alone, because a van tyre needs the correct load marking as well as the correct diameter and profile.
