Just be aware that most 'car tires' have a Max Load somewhere up around 1000kgs when they are inflated to their Max (cold) pressure of about 50 psi, but a normal car only imposes a load on each tire of about 2/3rds of that, so the tire only needs about 2/3rds of the maximum of 50 psi (or about 32-33 psi) in it for the air in the tire to suitably carry the load.... extrapolate that to take into account the lower weight of your Spyders & the air pressure required is usually only about 16-18 psi!! And this is reflected in the Load/pressure tables most manufacturers produce, even if they don't publish them like they used to! :sour:
AND be very aware that your tires
NEED to heat up a little in order to do their job properly. The tire carcass needs to flex in order to keep the tread flat on the road surface and both it & the tread itself needs to flex a little in order to create that small heat build-up and let the tread compound grip the road in the manner designed/intended - this flexing also allows the tread blocks & sipes themselves flex a little (but not too much) letting them effectively act (in concert with the tread grooving) as little 'continuously acting pumps' that will help clear anything (water, air, road debris, etc.... ) that might otherwise get trapped in the tread grooves & contribute to things like hydroplaning! That's how modern radial tires avoid that water pressure/inflation pressure thing.
So your tires need to be inflated to a pressure that is low enough to let all this occur, but not so low that the tire overheats, and this is where
YOU monitoring your tire pressure comes in!! Tire pressures
ARE NOT a
'one size fits all' thing, nor are they a '
set and forget' thing!!
YOU need to check your tire pressures regularly and be aware of what pressures you are running and how much your tires heat up thru use, as evidenced by the air pressure increase. Any increase of
LESS than about a 4psi after an hour's use means your cold start tire pressure was
TOO HIGH & your tire's grip, ride, braking, and handling suffers while your steering might
feel 'more direct', but because the tire is bouncing off the road surface it actually is not... plus, your 'inflated too hard' tire is more prone to punctures, slow leaks, & the resulting catastrophic failure those can bring; while at the other end of the scale, any increase of
MORE than about 6-8 psi means your cold start pressure was
TOO LOW and while your ride might be soft & cushy, your steering will be indirect & spongy and the tire is risking catastrophic failure due to overheating &/or delamination. :shocked:
And with all that in mind, it really is all up to each & every one of us to make sure that we are doing the right thing by our tires each and every time we use a vehicle! :thumbup:
