tyre pressure?

[Simonh]

for 15 inch alloys with 195/45/15 tyres what tyre pressure should i have...mine are too low but i dont know what to put them to

 

[Alienfish360]

Same as what it says on your door shut

 

[Simonh]

no because they are different alloys than what was originally on my car

 

[Alienfish360]

it's pressure not volume, a larger tyre will hold more air for the same pressure as a tyre with a smaller volume.

Keep your tyre pressures as specified by the manufacturer unless you have good reason to change them.

 

[Simonh]

oh right i didnt think it worked like that thanks alot

 

[Alienfish360]

The correct tyre pressure supports the weight of the car properly, naturally a larger tyre will take more air to achieve the same pressure, it's logical when you think about it

 

[jowley]

i found putting the fronts to 32psi and rears 30psi perfect

 

[Alexx117]

30 - 32 psi all round, i use 32psi saves fuel lol but your tyre manufacture should say the reccomended.

 

[Alienfish360]

Why would you want the same pressure in the rear than the front, when the rear has considerably less weight unless you regularly carry people in the back.

 

[Alexx117]

well i dont have any problems throwing it around corners

 

[burkey0013]

30psi

 

[Alienfish360]

Check your tyre wear after a few miles and see how even the wear is,

I've never ran my tyres to what it says on the door. 27psi i think it says, and all the garages etc used to charge them up to 32, front and rear.

Same Dont think anyone sticks to the recommended anymore :grinning:

A few miles? hehehe......nice one, (microscope anyone)

 

[James]

I run the correct pressures as according to my tyre placard - the ones for "110mph+" which is 35psi front, 33psi rear

 

[Alienfish360]

A few miles? hehehe......nice one, (microscope anyone)

few in comparison to the tyre life

 

[BG101]

I have mine at 33psi - I do regularly carry passengers but it also helps with handling

And what Alex said

yup!....I asked the tyre fitting center and I even rang up teh tyre manufactureres technical department when I first was upgrading.....neither of them knew any rule or formula...both said the same as Alienfish360)

for me stock tractor tytres wear perfect at 27, but when I went to brand new 195/45/14 (fronts) and 175/50/13 (rears) ....27 psi on these scuffed teh rubber rods offf the shoulders only....big rod-bumps still left in teh center for ages....


In the end I needed 31(ish) in the fronts and 30 in the rears for even wear (800Kg's worth of K10 and driver)....and the handling was miles better too
