fiddlehead Posted May 5, 2016 Share Posted May 5, 2016 I'm of the opinion that low tire pressure creates better friction, not less. Too much pressure can cause skidding easier than too little. Just my opinion. I must have missed the part saying his tire pressure was low. Link to comment Share on other sites More sharing options...
eisfeld Posted May 5, 2016 Share Posted May 5, 2016 Sorry just noticed she was the passenger.driver? Who knows but it looks like she never wore a seat belt. You seem to know everything. Well actually you know pretty much nothing it seems. Just trigger happy to senselessly rant a bit? Regarding the tire pressure: As mentioned by fiddlehead, low tire pressure actually increases friction and therefor grip due to the increased surface area of the tire that gets in contact with the asphalt. It increases tire wear though. Link to comment Share on other sites More sharing options...

Driving with low tyre pressures in no way increases grip, think about it, would a tyre manufacture produce a tyre that performed better at incorrect pressures.

Having seen many over here just keep pumping air into pickup tyres until they think it looks right or check it with a kick to the side wall I would say that anywhere near the proper pressure is probably considered low.

Driving with low tyre pressures in no way increases grip, think about it, would a tyre manufacture produce a tyre that performed better at incorrect pressures. There are disadvantages, like tyre life, heat etc., but in principle: lower tyre pressure increases grip. From the Michelin website. ROAD HOLDING With under- inflated tyres, the vehicle's steering is less precise. If a bend can be taken at 62 mph (100 km/h) at a tyre pressure of 29 psi (2.0 bar), this speed drops to 54 mph (87 km/h) at 15 psi (1.0 bar), or about 8 mph (13 km/h) less. Lower pressures = worse road holding AQUAPLANING If tyre pressures are 30% below the recommended pressure there is a sharp increase in the risk of aquaplaning. Lower pressures = higher risk of aquaplaning BRAKING In addition, tests show that braking distances from 56 mph (90 km/h) to 43 mph (70 km/h) are 40 metres at 29 psi (2.0 bar) but 45 metres at 15 psi (1.0 bar), that's 5m longer. 15 psi (1.0 bar) under inflation = 5m longer braking distance Link to comment Share on other sites More sharing options...

Guest Posted May 6, 2016 Share Posted May 6, 2016 It's good to remember that this time of the year the roads are very slippery when it rains. Lots of accumulated dirt and oil on the roads, which has not been washed out during the long dry period. Link to comment Share on other sites More sharing options...

richard_smith237 Posted May 6, 2016 Share Posted May 6, 2016 Got to love the tire pressure debate.... Adding to the mêlée.. If N2 is used would the pressure remain more consistent and last for longer or less ? (ok ok - don't go there... !)... On Topic: Speculation - this seems like a simple case of someone driving too fast in the wet !... Thats really it. We could go more into it - i.e. wet road, pickup, no weight in the back, rear wheel drive, greasy road due to fresh rain after a dry spell.... But really, its just poor driving... no real surprised there. Link to comment Share on other sites More sharing options...

This is obvious if you consider the extreme: a flat tire. But running just low pressure (a few psi under the rated value) increases traction. The examples from Michelin are 50% underinflated in two cases and 30% in one. That's HUGE. If you run way too low pressure then your vehicle will start wobbling around (road holding), have issues with big water patches (aquaplaning) or bad breaking. The tires might get also so hot that they drastically lose traction. The fact remains: a bit lower pressure increases traction under normal circumstances which is why amateur racedrivers usually underinflate the tires a bit. Rule of tump: try to always inflate tires to the manufacturers recommended values under normal circumstances. Note that there are pressure ranges under which tires can perform, not only one value. The pressure inside tires actually changes a lot during operation as the heat up. Link to comment Share on other sites More sharing options...
