Double check that you've entered the correct details e.g. entering letter O in place of a zero. Whilst we do have data for many Light Commercial Vehicles we can't always guarantee this. Unfortunately we do not currently offer motorcycle tyres, but there are other specialist fitting centres that can. Also, if you have recently transferred a personalised number plate it can take the DVLA a few weeks to update their database.
If your vehicle's details are substantially incorrect you should contact the DVLA.
Alternatively simply enter your tyre size e.g. 205 55 16 and speed rating for a full list of available tyres.
