245/35 R18 price per tyre by brand tier and season
A premium-brand 245/35 R18 tyre costs 32% more than a mid-range one (£144.13 against £108.89 median).
Budget brands save a further £31.62 per tyre at the median.
That mid-range median is about the same as the 18-inch average across all sizes (£107.10).
A row appears only where at least three offers exist. Run-flat tyres are excluded here and measured separately below.
| Tier | Season | Median | Middle half | Offers |
|---|---|---|---|---|
| Premium | Summer | £144.13 | £133.58–£147.81 | 14 |
| Premium | All-season | £149.19 | £147.29–£155.89 | 3 |
| Mid-range | Summer | £108.89 | £103.30–£118.32 | 21 |
| Budget | Summer | £77.27 | £68.70–£81.74 | 24 |
Extra load (XL) and run-flat versions
67 of the 69 offers are XL (reinforced) and 7 are run-flat.
There are fewer than three like-for-like XL and standard pairs in this size, so no XL premium is given. Run-flat versions cost a median 35% more than the same tyre without run-flat construction (4 pairs), and cost more to fit.
Fit XL or run-flat tyres where the car came with them: the load index and construction are part of the approved specification.
Fitted cost of four 245/35 R18 tyres
73 Auto estimate: four times the median summer tyre price plus a typical per-tyre charge for fitting, balancing, valve and disposal at this rim size (£32.00 per tyre). Run-flat tyres and SUVs usually cost more to fit.
| Tier | Tyre median | Fitting per tyre | Set of four fitted |
|---|---|---|---|
| Premium | £144.13 | £32.00 | £705 |
| Mid-range | £108.89 | £32.00 | £564 |
| Budget | £77.27 | £32.00 | £437 |
