Tyre Valves

[Darren P4]

Does anybody know what tyre valve the rover P4 wheel needs, mine's a 62 100, I suspect it maybe a TR414 but if someone knows for sure.

They come in two lengths, TR414 48mm and TR418 61mm, for 11.5mm holes.

Thanks colnerov, The TR414 looks about the right length so I'll go with that.

Note the wheels on a P4 were designed for cross ply tyres and although can be fitted with tubeless cross plys they are not really designed for tubeless radials. There is a lot of debate on this subject but I was warned by Rover engineers when I worked there and Michelin engineers, that a tube should be used with radial ply tyres when fitting to P4 wheels.

 

[Darren P4]

I didn't know that, thanks for the heads up, food for thought indeed.

That may well be true, and I'm not arguing the point, however most radial tyres have ribbed inner faces (for greater pleasure) and they can chafe the tube and puncture it. So check what's being fitted.
