Quick verdict

This MICHELIN Pilot Sport 4 SUV in 255/40 R21 102Y is best treated as a shortlist for shoppers who need the exact size and want a sporty, road-focused SUV tyre. The wider product positioning points more toward premium SUV summer or performance use than a true off-road or general all-terrain tyre, so it suits the right vehicle and driving style rather than every SUV owner. Because the retailer page could not be fully checked, verify the latest price, stock status and delivery charge before ordering.

Available tyre sizes and prices

Pilot Sport 4 SUV 255/40 R21 102Y All terrain is listed with 5 tyre size options from £278.15-£340.65. The visible tyre sizes include 255/40 R21 102Y, so use the table to compare the option that matches the exact size, colour, format or specification you want. Always confirm the final checkout price, delivery charge and stock status on the retailer page.

Key product details

These are the retailer details worth checking first for Pilot Sport 4 SUV 255/40 R21 102Y All terrain: Brand: MICHELIN; Type: SUV tyre; Season: All terrain; Tyre Sizes tracked: 255/40 R21 102Y. Treat them as a quick fact sheet, then use the retailer page to verify any installation, warranty, delivery or model-number details before buying.

What the product page evidence shows

The tracked product details confirm the brand as MICHELIN, the product type as SUV tyre, the tyre size as 255/40 R21 102Y and a tracked price band of £278.15 to £340.65 across 5 variants. During checking, the retailer page returned a 403 / “Just a moment...” response, so live listing details such as labels, delivery and final availability should be rechecked on the retailer page. On that basis, the safest approach is to rely only on the confirmed listing facts and not assume fitment, label values or stock beyond what is visible at checkout.

What the wider research suggests

Public product context places Pilot Sport 4 SUV as a premium SUV performance summer tyre, not a general all-terrain option, even though the tracked listing label says all terrain. That matters because it changes the buying question: this is more about road grip, sporty response and everyday SUV use than mud, gravel or mixed-terrain driving. No exact independent review was found for this Tyres.net SKU, so the review evidence here supports the product family only; treat the exact size as unverified until you confirm the vehicle placard and the live retailer page.

Buyer trade-offs to weigh before buying

The main trade-off is between exact fitment confidence and price. At 255/40 R21 102Y, this is a very specific SUV fitment, so the first check should be whether your current sidewall or vehicle placard matches that size, load index and speed rating exactly. Load index and speed rating matter here because they tell you whether the tyre is rated for the vehicle’s weight and the speeds it is designed to carry, so a mismatch is a fitment issue rather than a style choice. If you are comparing nearby alternatives, focus on whether another MICHELIN SUV option changes the tyre purpose, size or rating in a way that better matches your vehicle, rather than comparing brand name alone.

Price and value benchmark

At £278.15 to £340.65, this sits above the comparable-product median of £177.19, so it is not priced as a low-cost fallback. The broader product set also shows 5 tracked variants here versus a median of 1, which can be helpful if you are comparing different shopping routes or stock positions. Value therefore depends on whether the exact 255/40 R21 102Y fitment and road-focused SUV positioning are what you need; otherwise, compare alternatives before committing.

How it compares with nearby alternatives

The closest comparable options include MICHELIN Pilot Sport 4 SUV 255/45 R20 105W, MICHELIN Pilot Sport 4 SUV 245/45 R20 103V and MICHELIN Pilot Alpin 5 255/45 R20 105V. These are relevant because they differ by size, and the Pilot Alpin 5 also points to a different seasonal intent, so they are not direct substitutes unless your vehicle can accept them. If your vehicle can only take 255/40 R21 102Y, the comparison is really about whether this exact MICHELIN specification is the right balance of sporty road use, load/speed rating and spend.

How to read the review evidence

Owner-review evidence is thin here, with no meaningful review count visible and no exact independent review found for the 255/40R21 102Y Tyres.net SKU. That means you should not treat the available rating context as a strong verdict on this exact listing. The most reliable shopper signals are the confirmed size, the premium SUV road tyre positioning and the current retailer price and stock information, which should all be verified again before purchase.

Who it suits

This tyre suits drivers looking for a MICHELIN SUV tyre in the exact 255/40 R21 102Y size, especially where sporty handling and road use matter more than rough-terrain capability. It is also a reasonable shortlist if you want to stay within the Pilot Sport 4 SUV family and compare variant coverage across the retailer’s 5 tracked options. As always, confirm the size against your vehicle placard or current sidewall before buying.

Who should avoid it

Skip this one if you need a different season, a different load index or speed rating, or a tyre that is genuinely intended for off-road or mixed-terrain work. The retailer’s all-terrain wording should not be taken as proof that this is a true general all-terrain tyre, because wider public positioning points to premium SUV summer/performance use. If your vehicle does not call for 255/40 R21 102Y exactly, look for a closer match instead of assuming near-size compatibility.

Comfort, grip and efficiency checks

If the live listing shows labels for the MICHELIN Pilot Sport 4 SUV 255/40 R21 102Y, compare wet grip, fuel efficiency and road noise alongside the price band of £278.15 to £340.65. Those figures are especially useful on a premium SUV tyre like this because they help separate a sporty road choice from a comfort-first or economy-led alternative. If the labels are not visible on the retailer page, ask the shopper to verify them there rather than guessing from the product family alone.

Value check

Value here is less about chasing the cheapest tyre and more about paying for the right size, the right use case and the right rating. With a tracked range of £278.15 to £340.65 and live-page details not fully accessible during checking, the sensible move is to compare current price, delivery charge and stock status before deciding. If another option gives you the same fitment for less, or a better-matched season/specification for similar money, that may be the stronger buy.

Good alternatives to compare

The closest alternatives to compare with Pilot Sport 4 SUV 255/40 R21 102Y All terrain include Pilot Alpin 5 255/45 R20 105V All terrain, Pilot Sport 4 SUV 255/45 R20 105W All terrain, Pilot Sport 4 SUV 245/45 R20 103V All terrain. Use these cards to check whether a nearby model gives you a better price, a more suitable specification or a clearer match for your space and budget.
