Schwalbe Marathon Plus bumping along

Today I changed our my 700x28 Continental GP 4000 for a set of 700x32 Marathon Plus. I'm no great rider, but the 28's have good speed and with 80psi or less give a smooth ride of chip seal roads.

I had never used the Schwalbes until today. Anyway, I did a 15 mile ride today with the Schwalbes and coasting downhill on smooth road it was evident that something seems out of round. There was the rythmic bubump, bubump, bubump.

The wheels are XT hubs with Mavic A319 rims. The rims are rated to 80 psi, but I put 95 in the tires today to try and get rid of the bump...to no avail. I had this same problem with the Conti GP4000 tires until I once aired them to 110psi, then reverted back to 80 psi or so for regular riding. That seemed to sort it out and I had no more problems. Now, I change the tires in preparation for a week long tour in late November and the bubump comes back.

I might also add that I noticed a big different between pedaling the Conti and the Schwalbe tires. I suppose that is to be expected with a 1.3 pound per tire difference.

Anyone have any magic for putting the tires on right, the first time, so that they center perfectly on the wheel?

Schwalbe Marathon Plus have a very stiff sidewall. I usually pump them to 30 or 40 psi and then work around the tire while squeezing it. I've found that helps seating and centering problems.

Has anyone ever tried a soapy solution on the sidewalls/bead when you first put them on?

I tried for two days and couldnt even get the bloody tires on ! I gave up in the end and stuck with stock Bontragers on my trek 520. They're the most impossible tyres to put on ever!
