Mobile Tyre Fitting Marazion TR17 — St Michael's Mount to A394

Marazion and St Michael's Mount — Tourist Traffic and Granite Roads

Marazion is one of the oldest market towns in England and the closest point on the mainland to St Michael's Mount. In summer the town's car parks — the main beach car park off the B3280 and the smaller overflow behind Market Square — fill with visitors, hire cars and touring caravans. The granite shingle track that leads to the Mount causeway is a reliable source of slow punctures: small chips of Cornish granite work into tyre treads during the walk across and only become apparent hours later. If your tyre warning light comes on in Marazion after a beach visit, call us and we will come to your car park space.

Away from the tourist car parks, the TR17 postcode covers a cluster of small villages between Marazion and Helston: Goldsithney, Rosudgeon, Perranuthnoe and St Hilary. The lanes connecting these villages are typically a single track wide with passing places cut into the granite hedgerows. Our van navigates most of them — if a lane is impassable we will park at the nearest junction and walk. Give us a farm name, a chapel or a road number when you call and we will find you.

The A394 — West Cornwall's Main East–West Route

The A394 runs from Penzance through Marazion and south-east toward Helston and Falmouth, carrying a mix of local traffic, agricultural vehicles and summer tourist coaches. The road surface on the Marazion stretch was relaid in 2022 but the section between Goldsithney and Ashton retains the older chipped granite bound macadam that causes elevated tyre wear rates — particularly on the front nearside, which takes the brunt of the crowned road camber on this stretch.

If you develop a tyre problem on the A394, the safest stopping points are the farm entrances on the south side of the road between Marazion and Goldsithney, or the lay-by near the St Hilary junction. We know the road well and our response time from Marazion to any point on the A394 between Penzance and Helston is typically 20–35 minutes depending on your exact location.

Puncture Repairs in TR17 — BS AU 159 in the Far South-West

Puncture repairs in the Marazion area cost £35–£40 for most passenger cars. The process follows BS AU 159:f3 exactly: tyre removal from the rim, full interior casing inspection under a work light, combination plug-patch repair applied from the inside, then refit and balance. We carry our compressor and balancer on the van so the repair is complete on the spot — no driving to a workshop, no second visit.

To be repairable under BS AU 159, the puncture must be in the central three-quarters of the tread and no larger than 6mm. Sidewall damage from scraping Cornish hedgerow granite is not repairable under the standard, and neither are run-flat tyres that have been driven on while flat. If your tyre needs replacing rather than repairing, we carry common passenger car sizes on the van and can source less common sizes same-day with prior notice.

Coverage from Penzance to the Lizard Peninsula

From our Marazion base we cover the TR17 postcode in full and extend into TR18 (Penzance), TR19 (St Just and Land's End), TR20 (Ludgvan and Long Rock) and the upper TR12 postcode toward Helston and the Lizard. Response times from Marazion to Penzance town centre run to 15–20 minutes; to Mousehole and Newlyn it is similar. For Helston (TR13) allow 25–30 minutes and for the far Lizard peninsula at Lizard village, allow 45–55 minutes from call to arrival on clear roads.

The B3315 coastal road from Newlyn to St Buryan and on to Land's End is one of the more demanding routes in our coverage area — the road narrows significantly beyond Treen and the cliff-edge verges offer no safe stopping point in places. If you break down on the B3315, roll forward to the nearest hamlet car park (Treen, Porthcurno or St Levan) before calling us.
