:lol:

My digital pressure gauge is never more than 0.5 PSI out this is because it only measures in 0.5 PSI increments i.e. 28.5 > 29 > 29.5

I've also used gaffa tape on my winter tyres so they will grip better in the rain and snow

Great idea. I'm going to the hardware shop this morning.
Saw the forecast here and they're predicting 4 inches of snow and l have no chains.
The road clearing service is not good here, so using your idea, if l buy nails l can stick them through the tape and then wrap it around the tyres. I am using standard wheels and winter tyres.
So can anyone help me with how many nails l need to buy and what would be the most suitable length.

Or just put a few screws in there, only a few turns though

I got your message as l was buying the nails, so l took them back and brought some packs of these, hope they are long enough to see me throughout the hard German weather.

Just by way of interest, it's pretty cold here today. It got down to about -7/-8 here last night and hasn't gone above freezing all day. I took my wife's car out and, guess what, apparently all the tyres are under inflated according to the tyre pressure monitoring system. Reasonable evidence (to me anyway) that temperature can make quite a difference - more than 0.5 PSI I'd say. Foolishly, I also went for a 12 mile ride on my (pedal) bike. I wrapped up warm, but forgot to insulate my feet. Felt like they were going to drop off by the time I got home.

Just to play Devil's avocado, advocaat, whatever ( :P ), given that 0.5 PSI is actually a pretty small value, I do wonder if nlel's gauge is accurately calibrated. I mean, when it's reading 31.5, what is the actual pressure in the tyre? Has the gauge ever been compared against a reliable standard? If not, all this worrying about 0.5 PSI might be irrelevant. Unless it was very expensive, I wouldn't hold that much faith in a home-user gauge being 100% accurate to 0.5 PSI.

I guess the problem is how much does one need to spend to get an accurate gauge and who's to say it's accurate? Also does 0.5psi really matter for normal driving or are are some people paranoid? And pi** around too much

I've forgotten what tyre pressures are thanks to this thread. I should really go out and check them but it's damn cold and they look round.

Haven't checked mine in far too long. I normally run 34 front 32 rear. This is on 195/50 R15 Toyos though.

The issue is not so much being able to put an accurate value on the pressure reading - it is more about keeping the pressures the same across both tyres on the axle and looking for pressure loss (which of course indicates a leak).
