Heavy-Duty Trailer Security
The Bulldog TC250 Trailclamp is particularly suited to valuable car transporter and heavy-duty trailers where strong wheel security is required.
 
Its rolled-edge steel construction creates a robust physical barrier around the wheel, while the large front protection disc covers the wheel nuts to restrict access and help prevent unauthorised wheel removal.
 
Designed for Wider 155/70 R12 Tyres
The TC250 is specifically designed for the wider 155/70 R12 tyre configuration measuring approximately 170mm across the tyre.
This is an important distinction, as other Bulldog wheel clamps are designed for narrower 155/70 R12 tyres.

• 155/70 R12 tyres
