Tyres question

[lazybloke]

But to be fair if his mate hadn't been doing 90mph in a 45mph zone, that might have been less of an issue.

Quite, all this talk oversteer, old tyres being past their best, etc - might be of interest for those who drive like Senna.

Many of us prefer to drive at a speed where the dynamics of the car are tediously predictable even on old tyres.

It's a differential in grip F-R that's the danger, less so absolute grip in many respects.

Hitting standing water or suddenly coming off throttle /braking mid corner

You don't have to be driving like a tit

Never had that problem.
That sounds like driving into a corner too fast.


Re standing water, is that specifically a bald tyres thing? I allow mine to get quite low, but always replace them before they hit the legal minimum. It ain't rocket science to be careful in the rain, particularly if your treads are getting low.

I unfortunately had my fair share of driving like a bellend in a couple of hot hatches, but apparently with sufficient awareness of my (and the cars') limits because i never lost it on corners, snow, ice, mud standing water or anywhere else.

Four new tyres now fitted.

I'm now of the opinion that the old rear tyres were slowly losing pressure when the car was parked up for a period of weeks simply because they were old and no longer 100% airtight. Close examination revealed them to be very old and knackered looking.

You are wise.

I generally fit four tyres at once- you get 25% discount so only paying for 3 tyres. Always best to match tyres if possible

They don't have to be bald to lose it when hitting standing water but every mm will make a difference.

You could easily get caught out in a corner as no one has a crystal ball. What about driving at a sensible speed but then hitting a diesel spill or some mud/detritus on the road?

Go carefully for the first 100 miles on new tyres, and VERY carefully for the first mile. They need to scrub in a bit to achieve full grip, and brand new ones are usually slimy with mould release compound. I once had a set fitted and slid right into the first roundabout without stopping. Luckily everyone else did stop!

A bit late for that as I had them fitted a mile or so from home and naturally I drove like a loony after picking my car up.

But point noted.

Indeed. When a tyre has work to 3mm there is insifficent volume remaining in the treat to effectively accommodate the volume of water, and as water is incompressible it has nowhere to go and a car will begin to aquaplane. In short, despite legal limits etc car tyres are effetively scrap at 3mm.

Age expired tyres is what killed Paul Walker.

Was it road rage?

Yes, there are hazards on the road. Slow down.

Hopefully, the scenarios you list were theoretical for you, and not based on experience, but you did state the possibility of losing control simply from lifting off the throttle when cornering. Sounds like inappropriate speed to me!

I'm only stating reasons why someone fitting new tyres will put them on the rear and not front.

You don't have to be driving at an inappropriate speed for oversteer to happen given cirtain circumstances.

They shouldn't still be "slimy with mould release compound". That should be washed off before they are sent to the dealers (and not all manufacturers even use it any more). I think you were just unlucky with the set you had.
