My V11 has Michelin Pilots what are some of you running front and back.

Lately I'm running 34/37, F/R, and weigh 175.

OK Friz, but what do you weigh? C'mon, give it up. And be honest now...

34F 36R on Avon Azzaros - 170lbs

36 and 40 on Avons. I'm 170 lb.

[Guest MikeC]

Thanks guys, but no fair your all lighter than I am. I'm a bit over 200 and working on bringing that down.

Mike, a reasonable range of pressures will be suitable. Variables such as temperature, riding style, weather, tire design & compound, and load will shift your optimum pressures within that range. Of course all those conditions can vary independently within the same trip, or even within a few miles... Just another opinion here, but I'd say for most conditions, you'd be just peachy at your weight (assuming you're carrying no gear) at 36F and 40R (+/- 1lb.), and of course - work on bringing that down accordingly with your waistband.

This question comes up at a good time since I am just returning my new/old 2004 LM to the road. I have virtually no miles on it and am still learning about the bike so checked the owner's manual to find recommended pressure fr- 32, rear- 35. Those seem really low since most other mfr recommendations are in the 36fr, 42 rear range.

So, what are you hefty boys in the 200-205 lb range running? Further, isn't there a rule of thumb about proper tire pressure being indicated by a 10% increase in tire temperature from cold to hot?

[Guest ratchethack]

Tx, my best guess is that Guzzi recommends a low-pressure bias toward traction and adhesion at the expense of tire mileage, and publishes standard tire pressure the same way they spring the suspension - for a very lightweight rider.

 

You're absolutely right on the 10% rule-of-thumb, but I've never actually heard of anyone outside of a racetrack take cold and warm pressures and apply the old 10% rule. Where conditions are relatively static (a track) this makes a lot of sense, and you really need to be spot-on. On the road you have to settle on a range due to the varying conditions I noted above. Come to think of it, it's not a bad idea to run a check to see if you're in the ballpark for the road, and this weekend will be a great opp for Yours Truly to ck it out. Will do, and will advise.

I'll do like-wise. This'll be a good use for the new IR thermometer... I'll start with 36-40 and see how close to 10% that yields from cold. Incidently, thanks for your advice during the inspection/lubrication project of the LM.
