According to P3 parts list they are 5.75 x 16 , 4 ply rating or 6 ply as an option. The 17" wheel had 5.50 x 17 tyres. I believe 5.75 x 16 are difficult to find so its either 5.50 or 6.00. I personally wouldn't fit radials as to maintain the correct rolling radius it would need to be a 185/80 x 16 , which are about 1.5 inches wider, but I have seen 175/80 x 16 Taxi tyres fitted which equates to 5.50 x 16 cross ply rolling radius. The wheels are designed for tubes.

Thank you roverp480 for your reply,i have 195/75r16 T/L on at the moment they are 8ply light truck tyres and the are too rough and harsh. as long as the tyres are close to the old size it really does not matter as i have replaced the original diff with an early model range rover diff. thanks again for your information best regards Derrick.Smith.

I know a number of people up the gearing by fitting higher ratio diffs, so fitting tyres with a slightly lower rolling ratio will not be a issue . Yes the 8 ply rating will give a harder ride , better to fit 4 ply which a normal radial car tyre will be equivalent. Trust you have tubes fitted as both Rover and Michelin strongly advise doing. The higher cornering loads possible with radials , especially with a violent emergency manoeuvre can unseat the bead with a wheel not designed for a radial tubeless application, and cause immediate deflation.
