Thanks. Guess I'll just experiment with an extra a pound or two in each tire and see how it feels.

From my 2007 Suzuki C50 Owners Manual recommends different tire pressure dependent on if you are using their OEM windshield or not. They recommend the same tire pressure with minimal or full load something that surprised me. The only change for conditions they consistantly recommend is for with or without a OEM shield.

NO SHIELD 29psi FRONT 36psi REAR

WITH SHIELD 33psi FRONT 36psi REAR


The above recommendations are with the Stock Tires if you run another Brand of tire follow their recommendations for using on a Suzuki C50.
If they don't have a Suzuki C50 recommendation try the above numbers.

General Guideline: Front tire less than rear tire with more pressure in the front with a cruising shield over a naked bike do to the increased air force on the front tire when running at speed.

When I added an OEM shield to my bike I changed to the higher 33psi front pressure recommended by Suzuki for bikes with full size shields. my Bike with cruiser shield handles better with the higher 33 psi front tire pressure.

Different brands of tire require different pressure to give the tire proper handling properties when mounted on different Motorcycles. Motorcycle tire manufacturers will often recommend different pressure dependent on the bike and configuration. Some low sidewall strength bike tires need 40 psi to hold their shape on the road and others with stiffer side walls are best run with lower pressures in the 30s. The better manufactures of tires may be your best source for proper tire pressure for your specific bike when you substitute tires.

I have found with several bikes and lots of tires, that I prefer 38-40 psi front and rear. The bikes handle well, and tire life is better. Too low of pressures lead to more sidewall flex which increases heat. But the manufacturers certainly give good recommendations as a mix for handlng and comfort, and there is nothing wrong with sticking with what Suzuki recommends if it works for you.

Is adding a few pounds to the front if using a shield a rule of thumb? My OM does not specify a different PSI if using a shield.

The extra load makes sense to me - at this point - unless someone can come up with a better explanation.

I think that if there were a critical factor it would be in a competition mode where the factors would be calculated and compensated for.

OEM recommedations generally take into consideration both handling and comfort under 'normal' riding conditions, with comfort being primary for customer relations reasons..... so I don't feel bad adding a couple of psi to the pressures given in the manual.

'Normal' riding conditions, as I understand them, would be 1 rider 0 luggage and speeds under 70mph on a average spring/fall day..... YMMV

I would think its the additional weight and the air pressure the shield represents that is weighing down the front suspension and the recommendation of additional tire pressure.

My take on the 'windshield situation' is that the slant and the area of the shield are a source for down force loading of the front end due to wind resistance... That down force wouldn't exist with just the rider.

Im running the kenda kruz tires the max.psi is 40 so ive just been running the recomended 29f 36r. Looks like there wearing great at this pressure.

GrapeApe

The manual for the 2009 shows 29psi for the C50, and 33psi for the C50T or C50C (solo riding). I'm guessing this is due to the shield.

I'm running a batwing so I guess I'll need to up the pressure from now on.

Thunderhoof

This is what I'm doing too. And mine are wearing great too. But maybe I'll add a few pounds to the front trie since I'm using my larger "winter shield" these days and see if I notice a difference.
