Another unexpected bonus is that you will know for sure that you have the locking wheel nut doodad - and that it’s the right one, and that it works - before it’s 100 miles away in the back of the previous owner’s kitchen drawer!
When I got my NC it had cheapo no-name tyres on it that were checked/cracked all around despite only being about 4 years old. My local garage didn’t think it was a big deal, but a set of Kumho PS71s have made quite a difference to the ride - and I don’t have to worry about an abrupt tyre failure. I had that happen to me once many years ago and although I kept it out of the ditch - just - I certainly don’t recommend the experience.
Enjoy the ride home - hope the weather holds up for you!
I don’t approve of driving on dodgy tyres but years ago we all drove round in cars with no airbags,abs or any safety features on crossplys or even remoulds . Commercials run round on recut tyres down to 1mm dragging 40 odd tons , maybe sometimes we overthink things ? Personally I’d drive home on em no problems
I had similar cracks on the front tyres on my NC. It’s a second car, so limited use, especially in lockdown. So, two new tyres fitted ,pronto. Noticed an immediate improvement in steering response…
Had a MOT advisory for all 4 tires on my Nissan ‘damaged / cracking or perishing’ , 3 were 5 year old and one 4 years old (all Bridgestone’s). None of the tires looked anywhere near as bad as the one in the photo !
When I hit a brick sized rock at 70 on the motorway and buckled my alloy, the tyre held up but ended up with a 3" long tear in the same area as the cracks shown on the OP, and much deeper than them. The shreaded compound was hanging off, so I removed it. Yet I was told by the testing centre Black Circles sent me to that it wasn’t an mot failure. I was surprised.
