Avon Tire Pressures - From Avon USA

[AKRefugee]

I know that there have been several threads on this but I did not want this information to be buried.

 

I wrote an email to Avon questioning them about the optimum tire pressures based

on different weight configurations of the bike. Below is my query and the response.

I removed the reps name and extension number because I did not ask for his approval

to use his name.

 

I always carry a toolkit for both metric and standard (which by the way I have only had

to use twice and both times was for Harley's . . . just the facts ma'am) so that is why

the extra weight for the tool kit.

 

Anyway here is the information. Note that they did not provide me with a formula:

QUERY

 

Dear Sir or Madam,

 

I own a 2006 Yamaha Venture (Model XVZ13) I recently purchased the Venom rear tire for this bike.

I am on a very active forum for this bike and there has been much discussion about the appropriate

tire pressure. I would like to assure that I am using the correct information for setting my tire pressures.

 

The following are the weights applicable for my operation of this bike

 

Bike - XVZ 1300 Royal Star, Venture, Classic, Tour Deluxe

Tire Model - Venom

Tire Size - Front - 150/80-16 71H

Tire Size - Rear - 150/90B15 80H

Tool Kit - 15 Lbs

Rider Weight - 200 Lbs

Passenger Weight - 150 Lbs

Baggage Weight - 50 Lbs

 

 

It is my understanding that different weights will change the optimum tire pressure.

Can you please advise the optimum tire pressure for the following configurations as

well as if there is a formula I can use to determine the optimum tire pressure

based on load weight?

 

Configuration 1 - Tool Kit, Rider 36 front 42 rear

Configuration 2 - Tool Kit, Rider, Passenger 37 front 44 rear

Configuration 3 - Tool Kit, Rider, Passenger,Baggage weight 38 front 45 rear

 

Just thought that you might be able to use this information.

Do the cold pressures that seem to be recommended by Avon exceed the tire's max cold pressure on the sidewall?

[Wanderer]

Based on the information provided I would recommend everyone run 38 and 45 respectively.

If I were to come up with a formula for myself, wife(passenger), dog(passenger), and trailer I would have to inflate the tires to their rupture point or beyond. I'm thinking 59 front and 65 rear.

Oh well, good info none the less.

I wore a Avon out in less than 5k. It was bald!! I ran 38 to 40 in it most of the time and ride one up with a lot of junk in bags. Avon rep told me it was underinflated was reason it wore so quick. I didn't mention the twitch I have...
