New Tyre kills cruise control ??

[neilcharlton]

Just replaced the drivers side front tyre on my 1999 CLK due to a flat. It’s the same size tyre but different make etc.

On a drive up to Newcastle the cruise control refuses to engage in speeds over 80 mph.
Could this be down to the tyre change and the fact it wasn’t changed as a pair ?

Cheers

Hi Neil, this could well be the reason as the speed signal has to be accurate, and I suspect that at 80 mph it just goes out of spec for it to hold CC

Looks like a new tyre is in order ... there goes another 100 quid ! :-(

The new tyres should be fitted to the rear for the best safety, you could cruise at 70-75 and save your licence
