I have a 2005 Vulcan 1500 FI with wire wheels. I put Metzeler 880 Marathons on and discovered a "bulging" in the middle of the tire after 12,000 kilometers (approx. 8.000 miles) Metzeler's web site recommended front tire pressure of 38 psi front and 40 psi for the back tire. My Kawasaki manual recommends 28 psi for the front (which came with Bridgestone tires) but the dealers have said that's way too low. So now I've reduced the front to 32 psi (dealer recommended) does anyone have any idea what the right pressure should be?

I've experienced the same center of tread "bulging" on the front tires on my '09 1700 Nomad and '08 Yamaha FJR, both of which have Bridgestone tires. The bulge is caused by the center of the tread having a harder tread compound than the outside edges, therefore not wearing longer. Metzler is probably using the same multicompound tread, as are most other major tire manufacturers.

I think you meant to say you've increased the front psi from 28 (Kawasaki's spec) to 32, based on your dealer's advice. I'd be skeptical of any advice from a dealer that contradicts the factory recommendations, especially regarding tire pressures. 28 psi is the front tire psi spec for my 833 lb '09 Nomad and it handles just fine in all kinds of situations, including brisk cornering and carrying a passenger. Increasing air pressure above factory specs will probably have no significant effect on tread wear but it will change the handling of the bike. Be careful.

I put Metz's on the front and back and really like them. Especially if you ever ride on a grooved road!

It's my understanding that the pressure rating on the side of your tires are the MAX PSI that you should use. I am having a hard time buying that we should use the "factory" psi ratings on a diff brand tire than origanally came on the bike. Why would you use bridgestone specs on a metzler (or any other brand) tire? after all aren't the factory specs for "bridgestone" tires since that is what they come from the factory with?

max on the bridgestone is 41 PSI. I just put one on the back a couple of days ago.

I just bought a vulcan classic1500 with 25000 kms and have gotten a speed wobble 3 out of the 5 last rides, original tire size with dunlop tourings, the front tire is 28 psi, should I increase the pressure or decrease the pressure, everything checks ok on the bike and it was ok before the new tires other than the old front tire had some cupping from balance maybe, help, Kauctious, thought this was the bike, getting spooked,

The pressure info sticker is correct for any tire that goes on,not just the bridgestone.Thats there recommendation for the bike.

Metzeler recommends higher pressures for "improved mileage and customer satisfaction" than what the owner's manual suggests. They say that never should cold pressure be less than what the manual indicates.

Front Solo 36-38 2-Up 38-40 2-Up w/Load 40-42
Rear Solo 38-40 2-Up 40-42 2-Up w/Load 40-42

They also have guidlines for run-in for the first 200 miles and also a warmup of a few miles for every ride to get the best grip.
