Tyre Pressures...

[travellingkiwi]

What pressue do people run their tyres at? I've got stock E30 brdgestones on my 06 3.0d (19" wheels). The fronts are at the recommended pressure (Worn tyres, a warning on the edge of one last week). But the rears (Brand New) have been pumped up to 40odd PSI by the guy who fitted them.
Thing is, the ride is a truckload better than the original tyres that were on there even with the way high pressure. The tyres themselves say max pressure 51PSI... So they're not OVER inflated... But the recommended pressure (32) seems way too low...

That number for the rear is ONLY if you're loaded to the max. 32/32 is still the recommended pressure for normal loading (1 or 2 passengers)...and adjust accordingly as you load up the car.

Check the drivers door/jam. There should be a sticker telling you what pressures you should have by wheel size and load.

OK, Cheers... I never run max load... And yes I did check the inside of the door, but the discrepencies between the max, sticker and current was just too large to believe without checking.

In 8 years of serious high speed trips, and usually hauling lots of stuff,
I find that 39 rear psi useful when loaded to the gunnels. Otherwise,
32-32ish, imo.

I've been running 32 for 8 years on mine since I'm not running max weight. The only other passengers are my 31 lb Boston Terrier Chester and girlfriends (notice the plural ).
