A tiny bit help please....

[roland82]

Hi guys, Im a student doing mechanical engineering. Part of my course was to design a product. I designed a tyre valve which displays if the tyre pressure is too low using springs and coloured plastic inside the valve.

Any way part of the project is a survey about tyres. Its 10 questions takes about 1 minute and really help me out.

Thanks guys

Done.

If possible, it may be worth amending the question about the cost of a set of tyres.
I can't imagine many people spending less than £400 on a set of tyres (on here at least!).

Done.

On the first question there is no way to say more than 300 miles, I think you need to add this in as I (and others I presume) don't fit into any of the buckets currently...

Done.

I spend over £400 on tyres on a car worth less than 2 grand.

Done the survey none the less

Think they already exist, don't know if that has any bearing on your project?

Doing the survey now though.

Done, however for your last question it could be taken a few different ways.

I would potentially spend a lot of money on an accurate tyre pressure monitor, however just something that says 'tyre pressure low' and doesn't provide a warning in the car doesn't really help me if that makes sense.

Done - but second the above, try to make sure there's an option for everyone, even if it seems ridiculous to you! A thousand miles a week is not extraordinary.

And neither is <100 miles a week in your own car, if you spend 10 hours a day in a bus or lorry.

Done, good luck

Am I not allowed to have spent under 200 on my tyres?

Oh, ok... mine were 200quid a corner.

Survey Done.

Maybe it would be better to make clear whether the cost of the device was per wheel/tyre or per set. I bet a transponder and display unit would be cheaper, more robust and easier develop than a mechy one, but I guess your project needs to be mechanical.

Remember very few people will want to add something that makes their car look silly, so however this set-up works it will have to be very compact.

Good luck with the project and your studies in general.

+1 to the post below WRT need for some level of quantitive accuracy, otherwise you might as well just look at the tyre and see if it "looks flat".;)

I'd argue that the last question is ambiguous. I might happily pay 50 quid for a device which magically sends a text message to my mobile phone with my tyre pressures in it when I want it to, but certainly wouldn't for a pressure gauge that you have to put onto the valve because you can get perfectly functional ones of them for about ten quid.

I also wouldn't want anything that adds significant unsprung mass to the car.

Sorry, that did come across a bit 'Billy big Balls' didn't it...!
I appreciate there are cars that will be cheaper than that, but even the modest sized ones on my MX-5 were £400 a set.

[mat13]

Done

The tyres on my landrover are probably worth more than the car

[JonnyFive]

My MX5 tyres are £38 a corner, for Yokohamas, not ditchfinders..

But, you say "More than £150" etc.. Shouldn't it be less than £150, as more than £150 opens you up to anything above £150.

[jonstable]

Done. I work in the wheel and tyre trade, so may be able to help if you have any queries

[Mike 820]

Done the survey.

I check my tyres twice a week which is way more than your questionaire goes up to. Does that make me crazy?

[omgus]

Done.
