Since I have a wider tyre on the back (much wider) it has more area to fill up, thus, 48 PSi from the front would be equivalent to around 41 in the rears. And I have a pretty heavy sound rig in mine, I WAS running 44Psi before my rig. Yes it is bone hard to ride on, but I could bet my tyres would outlast most Z's tyres.. 76% tread, and I've done 34,000. *dance*
That doesn't sound right, the measure of weight per square inch doesn't vary when the surface area increases. More air (liters) will be required to achieve the same pressure, but pressure is pressure...
Nooo, I'm saying it in a non-technical way.. The amount of air in the front tyre wouldn't suffice for the back one.. I'm finding it hard to explain cause I dropped out in year 10 and don't know any technical mathematic terms or anything.. >.<'
How can you test tyres for a living, when you have difficulty getting your head around the fact that "48 psi in the front tyres" is identical to "48 psi in the rear tyres"? The cubic volume of different sized tyres will naturally be different(one from the other)but once pressurized to a given value(48 psi as an example)then they are all equally inflated.
Because if you can read "in a non technical way" you'd understand what I was meaning. I was "dumbing it down". I know that the cubic volume is equal in any form of tyre if it's measured in Psi, Kpa, which ever. I just worded it wrong in the first comment, because I didn't think people would mind about not going into full technical terms. If you wanna have a dig at my professionalism then go ahead, I'm all ears / eyes, and willing to have a giggle.
No one is "having a go" at you, you're the one who claimed to have a lack of knowledge or ability due to "dropping out of school".
My guess (being a non professional in any field relating to tires must make this almost infallible right) the wider tires are getting the lower the profile to keep the same circumference. the lower the profile the higher the pressure suggested on the tire. well that seems to me the basic rules. reasoning I have no idea, but on any wheeled vehicle I have owned the lower the profile rating (no matter how wide) the higher the suggested operating pressure has been. example my wifes 215 50 17 are recommended at 40-45 my 225 60 16 are 35-40
Just bought 4 x Nexen 6000s $600 fitted 2 - 235 x 45 x 17 2 - 255 x 40 x 17 I've been happy with the 3000's, so I'll give the 6000's a go.
Pexzed you got them at a good price. CHILI, sometimes you go about typing things in an aggressive matter, take it out on the track, not on members. Stumagoo is pretty well on track.. But I have my reasons for running high pressures. I don't mind the hard feel. Like I said, if you find the perfect balance between comfort and safety, you're in the green zone. Comfort, safety and fuel econ? :thumbup: You'll notice a difference in tyre life and fuel econ with higher pressures.
If you want to persist with the "I've got a chip on my shoulder" attitude, then that's your choice. I should point out to you, that several people questioned your inaccurate advice/logic re tyre pressures, but if it makes you feel good to identify me as the "non-believer" go right ahead. I don't doubt your good intentions with regard to tyre comparisons, just your accuracy. Cheers Lloyd
