Re: 95 540i w/ M5 Wheels - Recommended Tire Pressu (archive)

I've been having tirwear nearest to the inside and outside on the fronts and inside only on the rear, so i adjusted according to the tire pressures listed on the door. The door lists either 38 front/41 rear or 41 front/44 rear, which I am now trying the later of the two choices. Hopefully this will cause a little more wear in the middles that on the outsides.

Are you refering to the 1995 18" ///M parallels? If so, I run mine at 40psi all around.

Does anyone know the recommended tire pressures for the 95 M5 wheel & tire combination on the E34?

I have the ///M Parallel 18s and I run them according to the 2000 M5 pressure recommendation of 44/49. I figure the weight distribution and overall stance/design is similar to the E34 cars and it is a 18' rim tire combo. So far my Pirelli P7000SS have not show excessive wear on the outsides, but rather pretty even wear. The high pressure has not affected ride quality much, instead it has enhanced cornering stability and overall grip. I've read almost everywhere that its better to over inflate a tire than to underinflate them and run too low. Low pressures lead to increased wear and possible damage to the innards of the tire. The extra pressure also provides a better protection against potholes that may dent the rim, since the distance from rim to ground is increased slightly. Try out the 44/49 combo and see if you like it as much I do. The max pressure on my tires are 51psi, but I don't fear any rupture since Pirelli makes a great tire.
