Re: tire pressures for avons

I run 42/48 regardless of loading. Hit the scales @1450 lbs one time, I stay away from the scales now
Ran loaded like that on Hwy1 to the Bay area and back with no issues.
Works just fine.

Re: tire pressures for avons

Look on the side of the tire and it will tell you the max pressure to run. Run the max pressure.................

Re: tire pressures for avons

I run 38/42 one up exclusively. My LT is setup for 230 LBS rider and luggage.

I am ready to replace this set (will be my third) and I have just over 12K with a little more to the wear indicators. I came upon this pressure by monitoring the tire temps using my Smartire TPS. I used Stones after my first tire change and I never had both tires wear to replacement at the same time. So this is a first.

Re: tire pressures for avons

I've run probably at least 10 sets of Avon S2 Ultras on my '05 LT, and the max pressure posted on both tires is 42. I stay with that, sometimes a lb over. Nice, smooth running tire compared to the bias ply Metz.

Re: tire pressures for avons

Wow. so many different pressures!
I spoke directly with Avon Tech on this issue and was told this. Start at 40F and 44R and adjust according to peak pressure at operating temp. He said you want the tire to increase 10% when it is fully hot. If it is too low the pressure will increase more and if it is to high it will be lower than 10%
He said to ignore the max pressure on the side. Its for chumps

I've gotten the same info from an avon tech rep, minus the "chumps" part. In fact some of his exact words were " there are 10 things that effect the life of the tire. The first is pressure. the second is pressure. the third is pressure, the fourth is pressure. want me to keep going?"
I got the point! Steve

Re: tire pressures for avons

Avon rep and a bridgestone rep told me same thing. i run avons now for last forever. 10+ sets
Just use the 10% rule and ignore the side pressure.
Mine seem to be at 43/48.

45 years riding and still more places to see.
